1 BOLDStone Garage Floor Application Information 2010 Applying BOLDStone products over concrete is not difficult, but there is more to it than simply painting the garage floor. This guide will take you through the steps: 1) Deciding which BOLDStone coating products will best provide the desired results, 2) Measuring the area and calculating how much material (and other products) will be needed, 3) Preparing the concrete surface, 4) Applying the material, 5) Cleaning up, and 6) Maintaining the floor. Decisions will need to be made concerning the desired look of the floor and the costs vs. durability. This is not an easy task. You may desire a certain look and it may be impractical for the use of the space. Or, the cost may be low, but the maintenance could become a nightmare. I. Selecting BOLDStone Floor Coating Products This guide addresses issues applying BOLDStone on a horizontal concrete substrate only. (Much of this information also applies to the application of BOLDStone on vertical or inclined concrete surfaces, but there are differences. If you need to coat walls, columns, supports, or other vertical surfaces, consult BOLDStone s Application Instructions for Vertical Surfaces information. BOLDStone also carries a complete line of primers for application on other substrates such as asphalt, wood, metal, and previously coated surfaces). After taking into account what type of substrate is to be coated, the next consideration is the environment of the area to be coated. Whether you are a homeowner and want to "paint your garage floor", or you are coating a large commercial automotive service area, there is a BOLDStone Coatings product to fit your need. 1

2 Finish texture must be taken into account. Floors which must stand up to high traffic, high impact, extreme temperatures, acids, or other chemicals need special consideration. There are special formulations for extreme temperatures, (such as refrigeration or freezer floors), coatings for high-impact floors (such as industrial or manufacturing environments), special formulations for food handling areas, coatings for automotive service areas, and coatings for acid or other chemical handling areas. Be assured that BOLDStone offers a complete line of residential, commercial, and industrial coating products. NOTE: Since many customers have requested information about the traditional residential 2-car garage, the rest of this application guide will be dedicated to the use of BOLDStone products applied to this type of application. (The procedures can easily be adapted to other types of concrete applications). For a standard residential 2-car garage floor project, BOLDStone recommends using our 1) BOLDPrimer, which is a primer and sealer for concrete, 2) BOLDGranite body/texture coat with BOLDFloor Hardener 100 as an additive, and 3) BOLDFloor Commercial Duty Topcoat, which is our clear, solvent based, Polyurea/Polyaspartic hybrid material (high gloss, 92% solids, "two part"/"a-b" mix) II - Measuring the area and calculating for materials One of the first questions customers ask is, "How much material will I need?" To calculate how much material to order, you will need to measure the length and width of the area in inches or feet. Now multiply the length times the width. If your measurements are in inches divide by 144. This will give you the size of the area in square feet. If your measurements are in feet, then the product of the measurements will already be in square feet. In our traditional 2-car garage example above, the length and the width of our floor is 24'. So, the square footage of our project would be 24 x 24', or 576 square feet. When estimating how much material you will need, always round your figures up. It is better to have a small amount of material left over than to run short while applying the coatings. 2

3 1) BOLDPrimer is supplied in a 5-gal pail that can cover up to a 1600 sq ft area. Therefore, in our example above, only one pail is needed for this project. 2) BOLDStone Body/Texture Coats are supplied in 5-gal pails. A. BOLDGranite can cover 100 sq 1/16 th inch in thickness. Therefore, take the total square footage of the project, 576, and divide by the square footage each pail of material can cover, 100 sq ft. This means we will divide 576 by 100, which equals 5.76 pails. You would need to order 6 pails of BOLDGranite for this project. B. If BOLDFinestone was to be used on this project, divide the total square footage of the floor, 576 sq ft, by the square foot coverage per pail of BOLDFinestone, (BOLDFinestone coverage is 110 sq 1/16 th inch in thickness). Therefore, divide 576 by 110, which equals 5.24 pails. Again, you would need 6 pails of product for this project. 3) BOLDFloor Topcoats are a little different to figure out. First, decide what BOLDFloor Topcoat to use. Either 1) BOLDFloor Heavy Traffic Topcoat, which is our clear or satin, water based, high solids, "two part" ("A-B" mix), aliphatic polyurethane, or the BOLDFloor Commercial Duty Topcoat which is our clear, solvent based, 92% Solids, "two part" ("A-B" mix) aliphatic polyurea/polyaspartic hybrid material, or 2) BOLDFloor High Build, which is our clear, high gloss, 100% Solids, "two part" ("A-B" mix), epoxy. Once you have calculated the project area, calculate how many coats of the BOLDFloor Topcoat needs to be applied to achieve the desired look or thickness (which is measured in "mils"). A. BOLDFloor Heavy Traffic Topcoat has been developed as a high performance finish coat for various seamless flooring, coating, and architectural concrete applications where odor cannot be tolerated. It is the ideal topcoat for areas that require maximum sheen retention, ease of cleaning, and resistance to heavy foot traffic. Typical areas of application would include clean rooms, hospitals, concrete counter tops, and high traffic retail areas. BOLDFloor Heavy-Traffic is also suitable for aircraft hangars, automotive repair facilities, and garage floors. It is available in gloss and satin finishes. This product is sold in a kit. Each kit contains two parts ("A-B" mix). When part A and B are mixed together they make 1.5 gals of product. This mix (1.5 gals) will cover approximately 400 square 3 mils thick. (DO NOT APPLY ANY THICKER THAN 5 MILS IN ONE COAT). Multiple coats can achieve a smoother finish, however, the first coat needs to be tacky before a second coat is applied. If the desired look is closer to a polished floor, then use our Commercial Duty or High Build products (see below). To figure out how much material to order for our 2-car garage project above, take the total square footage of the garage, 576, and divide by 400 sq ft. This equals 1.44 kits. You would need to order 2 kits for this 3 mils thick. If the desired look requires two coats, then multiple 1.44 kits times two, which is You would need to order 3 kits for this 6 mils thick. B. BOLDFloor Commercial Duty Topcoat is the hardest and most durable Topcoat BOLDStone sells. This is the product that we recommend for garage floor projects. This product is sold in a kit. Each kit contains two parts ("A-B" mix). When part A and B are mixed together they make 1.25 gals of product. This mix will cover approximately 250 square 8 mils thick. (DO NOT APPLY ANY THICKER THAN 16 MILS IN ONE COAT). Multiple coats can achieve a smoother finish, however, the first coat needs to be tacky before a second coat is applied. If the desired 3

4 look is closer to a polished floor, then either apply several coats of the Commercial Duty topcoat, or use our High Build product (see below). To figure out how much material to order for our 2-car garage project above, take the total square footage of the garage, 576, and divide by 250 sq ft. This equals 2.3 kits. You would need to order 3 kits for this 8 mils thick. If the desired look requires two coats then multiple 2.3 kits times two, which is 4.6. You would need to order 5 kits for this 16 mils thick. C. BOLDFloor High Build Topcoat is the product to use if a smooth polished floor look with a quick application is desired. (Caution: This type of floor is soft and can be indented fairly easily. It can be very slick with a very low co-efficient of friction. This is similar to all epoxy floor coatings without the aluminum oxide chip topping.) This product is sold in a kit. Each kit contains two parts ("A-B" mix). When part A and B are mixed together they make 2.95 gals of product. This mix will cover approximately 150 square 32 mils thick. Multiple coats can achieve a smoother finish if desired. To figure out how much material to order for our 2-car garage project above, take the total square footage of the garage, 576, and divide by 150 sq ft. This equals 3.84 kits. You would need to order 4 kits for this 32 mils thick. If the desired look requires two coats then multiple 3.84 kits times two, which is You would need to order 8 kits for this 64 mils thick. NOTE: BOLDFloor High Build Topcoat is not recommended for this type of garage floor application because the heat and weight of vehicles and equipment could indent the topcoat, if the topcoat is applied thicker than 16 mils. III Concrete Surface Preparation (For complete detailed information, see our separate technical sheet called Guideline Instructions for Concrete Surface Preparation ) Proper concrete surface preparation is essential to obtain the best results for coating garage floors with BOLDStone coating products. Concrete is a mix of Portland cement, sand, stones ("aggregate"), and water. Concrete floors, in different situations, require different preparation before BOLDStone coatings are applied. Concrete may be a new pour, (concrete which was recently poured), or it may be an older concrete floor and be dirty, stained, cracked or crumbling. The floor may have been previously coated or painted. 4

5 Is the concrete that you want to coat a new pour? It is suggested that you wait a minimum of 28 days if applying BOLDStone coatings over a new pour. For concrete over 4" or 5" thick, it is suggested that you allow even longer for the concrete to cure. To test if concrete is fully cured (or if there is still moisture present), tape a 4' x 4' sheet of clear plastic in middle of the floor and leave it in place for 24 hours. If the concrete is not fully cured, moisture will be trapped beneath the plastic sheeting and the surface of the concrete will appear dark or wet in that area. Remove the plastic and allow the concrete to fully cure. Repeat the test once every 3-5 days until there is no noticeable difference in concrete appearance beneath, and around, the plastic sheet. NOTE: If several weeks go by and moisture is still present, it may be due to hydrostatic pressure from the earth below the concrete. (It is possible that no moisture barrier was installed under the slab.) If the concrete floor you want to coat with BOLDStone coatings is in fairly good condition (no heavy oil staining, no crumbling and concrete was not previously coated or painted), you will still want to thoroughly clean and etch the surface to insure a good bond between the concrete substrate and the floor coating. Does the concrete show signs of efflorescence? The surface of freshly cured concrete may sometimes have a milky-white residue. This is called concrete efflorescence, and must be removed prior to the BOLDStone coating application. Efflorescence is the deposit of salts (calcium, sodium, potassium, magnesium, chlorides and sulfates), which rise to the surface of concrete. Heavy accumulation of the efflorescence can be removed with a stiff brush. Residual salts can be removed by washing with clear water. On older concrete floors where efflorescence salts have formed into calcium carbonate or magnesium carbonate deposits, removal with a chemical cleaner or acid may be necessary. NOTE: Efflorescence salts clog the pores of concrete and may cause bonding problems between the BOLDStone products and the concrete. 1) Cleaning Concrete Floors Begin by sweeping and/or blowing away any heavy accumulations of dirt or loose debris. Be sure to blow or sweep away any leaves, dirt, and debris from the surrounding area that could blow in through the garage door (a pressure washer can be used for this if you don't have a blower). 5

6 When using a pressure washer, thoroughly wash every inch of surface to be coated. (If you do not own a pressure washer, they are available at most tool rental centers. We suggest using a pressure washer with between 2500 and 3500psi). Be careful! The force of water can be very powerful and a high-powered pressure washer can actually cut into concrete. Note any area where water appears to bead or is repelled. This is an indication that there may be wax, grease, motor oil, transmission fluid, or other oily residue in the substrate. If this is the case, use TSP (Tri-sodium-phosphate) or other degreaser and scrub the area until water will penetrate the surface. Wash again with the pressure washer after using any degreasing agents or cleaners. After pressure washing, examine the surface closely. You may find cracks, low or high spots, or other defects in the surface, which should be repaired to achieve the best finish possible. BOLDStone coatings may fill and bond very fine hairline cracks, but larger cracks require the use of crack filler. For extremely wide, jagged and/or deep cracks, you may need to grind out concrete, and patch using an epoxy/concrete patching kit. If there are low spots in the concrete floor, use an epoxy patching compound and trowel mix onto the surface to level the low areas. 2) Etching Concrete Floor Once the entire floor has been pressure-washed and degreased (if needed), the entire surface must be etched to insure a proper bind between the BOLDStone system and the underlying concrete floor. To etch the concrete, mix equal parts of muriatic acid and water and disperse over the surface of the concrete floor. Allow the acid to sit on the floor for approximately 20 minutes. Rinse thoroughly with clear, clean water until all remaining acid has been washed away. (You may want to use an alkali-based cleaner to neutralize the acid before continuing). If a grinding machine is used to abrade the concrete, see the above instructions for cleaning the dust and chips from the area. IV - Applying the BOLDStone System (For complete detailed information, see our separate technical sheet called Application Instructions for Horizontal Surfaces and the specific data sheets for the products that are to be applied. READ ALL SAFETY INSTRUCTIONS BEFORE CONTINUING.) Once a concrete floor has been properly prepared (cleaned, degreased and etched), there are two factors that must be taken into account at the time the BOLDStone system is applied. The two factors are temperature and humidity. These factors will affect the outcome of the application. In general, the BOLDStone system should be applied when temperatures are between 50 and 80 degrees Fahrenheit. Humidity should be no higher than 80 percent, (the lower the humidity, the better). 6

7 Be aware of temperature or humidity level changes that will occur during the course of the application and drying time. Although you may start an application at 7:00am and the temperature is at 60 degrees, by noon the temperature can, and most likely will, rise or fall. In many cases, afternoon temperatures will rise even higher than noontime temperatures. You must be sure that the temperature will remain within recommended levels during the BOLDStone coating application and drying times on large commercial jobs or when applying the second coat to smaller jobs. 1) Applying the BOLDPrimer A. Addition of water. You may wish to use a separate container to mix only 2 gallons of BOLDPrimer for this 2-car garage project. Properly seal the remaining 5 gal pail for future use. Depending on the temperature, humidity, and equipment used, you may add up to 1 part water with 3 part BOLDPrimer. (NO NOT ADD MORE THAN THIS. TOO MUCH WATER DILUTES THE ADHESIVES IN THE ACRYLIC BINDER AND MAY RESULT IN POOR ADHESION TO THE CONCRETE). In our 2-car garage example that will mean ½ gal of water could be added to 1 ½ gals of BOLDPrimer. (If several 5 gal pails are to be used on a single project, add the same amount of water to each pail.) B. Addition of pigment. Add acrylic pigments (found at a local paint store or contractor s supply house) to the white colored BOLDPrimer to closely match the BOLDGranite or the BOLDFinestone body/texture color coat. (The tinting of the BOLDPrimer does not need to be an exact match to the body/texture coat color.) The BOLDPrimer is tinted because the acrylic binders in the body/texture coat along with the ceramic sand are translucent. Since the body/texture coat will only be 1/16 th inch thick, the white color of the BOLDPrimer may appear through the body/texture coat in some areas. (If several 5 gal pails are to be used on a single project, add the same amount of pigment to each pail.) C. Mixing the BOLDPrimer. Mix thoroughly even if water and/or tints are not added to the BOLDPrimer. The BOLDPrimer should be mixed for approximately 1 minute, or until a consistent color is obtained when pigments are added. Use an appropriate mixer powered by a half-inch drill at RPM just prior to application. Do not overmix. D. Applying BOLDPrimer. BOLDPrimer can be sprayed, rolled, or brushed onto the garage floor. BOLDPrimer is designed to impregnate the concrete to help stop the transmission of water from below, while creating a viable base to which the body/texture coat can adhere. However, if the primer is completely absorbed into the concrete, then the primer was probably thinned too much and will now require a second coat. The BOLDPrimer should only be a few mils thick. Do not apply too thick. E. Drying Time. The drying time of BOLDPrimer is dependent on the temperature, humidity, and thickness of the primer coat. On the average, the BOLDPrimer should be dry to the touch within 1 hour of application. 2) Applying the BOLDGranite or BOLDFinestone body/texture coat A. Addition of water. After the product has been mixed, the body/texture coat should flow well enough to be sprayed with a hopper gun or a spray pump without the addition of water. However, if the material will not spray easily after mixing, water can be added in small increments until a consistent material flow is obtained. The same amount of water must be added to all pails of a given batch. 7

8 Do not exceed 16 ounces per pail. (Some compensation for evaporation may be made.) A BOLDStone Field Service Manager should be contacted if a given batch of BOLDStone needs more than 16 ounces per pail of water to spray properly with a hopper gun. Customer service information can be found at B. Addition of the hardener. Add the entire contents of BOLDFloor Hardener 100 (approx. 14 oz.) to each 5-gallon pail immediately before application. (BOLDFloor Hardener 100 is used for all horizontal surfaces, including counter tops). This additive not only hardens the surface coating, but it will also shorten pot life. Therefore, only mix what you can easily apply in one hour. C. Mixing the body/texture coat. When first opening the body/texture coat pail a layer of liquid acrylic may be found on top of the material. This is normal. Mix the contents even if water is not added. The BOLDStone body/texture coat should be mixed for approximately 1 minute with an appropriate mixer paddle powered by a half-inch drill at RPM. Mix just prior to application. Add only enough water to allow the material to flow. See the Hopper Gun or Sprayer Pump specifications for adding water recommendations specific to each type of spray equipment. Mix all the pails the same length of time, and add the same amount of water to each pail for a particular batch. Do not overmix. D. Applying the body/texture coat. This product does not spread easily or consistently with a paint roller. Therefore, only a spray technique will be discussed here. Use an inexpensive hopper gun in conjunction with an air compressor or a Graco RTX 1500 pump (or equivalent) for a quality application.

9 1. Air Pressure and Orifice Openings a. Different textures are achieved by regulating the air pressure, moisture content, spray gun orifice size, and application pattern method. The higher the air pressure, the finer the texture. By decreasing the air pressure, the texture will be heavier. Be sure to keep the air pressure consistent throughout the project. The air compressor should maintain a constant air pressure without surging. Surging will cause texture variations. A compressor capable of maintaining 7 cubic feet per minute (CFM) above working pressure or a minimum tank pressure of 80 PSI is needed for spraying with most hopper guns. Be sure the compressor to be used is adequate to comply with the spray gun manufacturer s specifications. A working pressure range of 10 to 25 lbs. as determined by an air pressure gauge at the hopper gun worked well with our generic hopper gun and should be a common pressure range. Check your hopper gun specifications for specific pressure details. The applicator must find and maintain the pressure that produces the most desirable spray texture. Make a test area and track the pressures and textures to find the best overall pressure. The pressure should be noted so as to maintain it consistently throughout the project. When using an air-operated hopper gun (drywall mud style), add a small inline regulator at the air inlet on the gun for best effectiveness. Air pressure should be consistent and maintained at about 10 to 25 psi. When pressure is regulated at the air compressor outlet, surging will occur and cause variations in your finish. This happens because of the pressure stored in the hose after the regulator. b. The common orifice openings for BOLDStone finishes are 1/4", 5/16" or 3/8". The larger the opening, the heavier the spray texture, and the smaller the opening, the finer the spray texture. Orifice openings are also specific to the largest grain particle. If you are experiencing orifice clogs, you are probably using too small of an orifice. Orifice openings smaller or larger than those listed above should not be used. The orifice plate must be inspected after spraying each section and cleaned if needed. Excess material obstructing the orifice plate can change the texture delivered to the surface. (At the minimum, examine the orifice daily and the entire gun every 1000 square meters for wear. Replace as needed, or as recommended by the equipment manufacturer) 2. Spray and finish texture techniques a. With the appropriate spray equipment and spiked shoes, apply the BOLDStone body/texture coat 1/16 th inch thick over the colortinted BOLDprimer base coat. Spray an initial pass left to right or up and down, striving for a uniform coat covering the color-tinted BOLDPrimer. Small circular motions should be made with the spray unit while spraying. The spray unit, either hopper or wand, must stay as perpendicular as possible to the surface at all times and never be closer than 18 inches to the surface. The individual spraying should focus his attention on the area of contact. (approximately 10 inches in diameter where the material spray is highly concentrated). Follow this contact point closely when 9

10 spraying. In doing so, the surface will be uniformly coated without a blotchy appearance. Spray a full section or to a natural break or joint in the surface before moving backward with a second pass. b. If a second pass (touch up pass) is needed or desired, move back with a lighter second pass perpendicular to the first. Remember not to apply BOLDStone body/texture coats more than 1/16 th inch thick for garage floor installations. The second pass should be made when the material is still wet or tacky. Never allow the finish to be dry to the touch before spraying the second pass. While applying this touch up coat, spiked shoes are a necessity and the applicator must be careful not to drag the spray gun hose through the freshly sprayed substrate. (The applicator will have to walk over the freshly coated surface to do the touch up). Strive for a uniform appearance, again focusing on the area of contact as described above, and move on. Avoid spraying too thick. If the coat is sprayed on too thick, problems such as improper curing, shearing under vehicle weight, and slumping off of vertical surfaces can occur. All surface sections must be sprayed with the final pass in the same direction, either left to right or up and down. c. Final texture can vary depending on the different application methods. Some standard techniques would be troweling flat, backroll rough, back-roll smooth, or back-roll flat. (Foam roller knockdown textures must be completed while the texture is still moist. Trowel knock down textures can be done up until the texture sets firmly). The length of time between application and texture finishing will alter the look of the finish, so consistent timing will give you more consistent texture results. The applicator can achieve a range of textures from split or sheer face stone look, to a flat finished stone appearance. (The applicator is responsible for the final appearance of the texture; be sure he is proficient at producing the desired texture). d. Since no two applicators will have the identical spraying technique, the most uniform results will be obtained if one applicator can spray the entire project or section. If this is not possible, insure that each applicator is using the same type of equipment, pressure level, spray gun orifice opening, spray angle and keeping the same distance(s) from the surface, while using as consistent a technique as possible. E. Drying Time. The drying time for BOLDStone body/texture coats is dependent on the temperature, humidity, and application thickness. On the average, the BOLDStone body/texture coat should be dry enough to walk on (without spiked shoes)and to apply the clear topcoat within 2 hours of application if the temperature is 70 o F and 55% RH. However, it is advised to test the surface in an inconspicuous area for dryness. Cooler and/or more humid conditions will require a longer cure. Temperatures should remain above 41 F (5 C) during the cure period. The BOLDStone finish must be allowed to fully cure before being exposed to rain or freezing temperatures. 3) Applying the BOLDFloor Topcoat 10

11 A. Addition of water or solvents. Unless you are a professional and know exactly what you are doing DO NOT ADD WATER OR SOLVENTS to BOLDFloor Topcoats. B. Mixing the Topcoat. When using BOLDFloor Topcoat Heavy Traffic, Commercial Duty, or High Build, insure that the entire contents of Part A and Part B are mixed thoroughly before application. (Be aware that the amount of material found in container Part A is different than what is in container Part B). Only mix what can be easily applied in 40 minutes. The BOLDFloor Topcoat should be mixed for a minimum of 2 minutes, but no more than 4 minutes, with an appropriate mixer powered by a half-inch drill at RPM just prior to application. Do not mix air bubbles into the topcoat. C. Applying The Topcoat. After the BOLDStone body/texture coat is completely dried, apply the appropriate BOLDFloor Topcoat. BOLDFloor Heavy Traffic can be applied by a paint sprayer, brush, or roller. The BOLDFloor Commercial Duty topcoat can be applied by brush or roller. BOLDFloor High Build Topcoat can be applied by brush, roller or squeegee. Do not apply too thick in one coat. If a thicker topcoat is desired, add a second coat while the first coat is still tacky. You will want to begin applying the topcoat at the furthest point from the door(s) using a paintbrush and cutting in some edges, inside corners, doorway openings and other areas where the topcoat cannot be easily applied with a roller. Do not cut in too far ahead to prevent the topcoat from creating a dry edge. After cutting in, begin to roll the floor using a paint roller with a solvent resistant phenolic core, shed proof, epoxy roller cover. You will "paint your way out of the garage, so that you do not need to walk on the wet topcoat, or drag equipment or materials across the wet areas of the floor. Continue to cut in and roll areas, always applying wet topcoat to wet topcoat until the entire floor area has been coated. 1. BOLDFloor Heavy Traffic Topcoat. BOLDFloor Heavy Traffic has been developed as a high performance finish coat for various seamless flooring, coatings, and architectural concrete applications where odor cannot be tolerated. It is the ideal topcoat for areas that require maximum sheen retention, ease of cleaning, and resistance to heavy foot traffic. Typical 11

12 areas of application would include clean rooms, hospitals, concrete counter tops, and high traffic retail areas. BOLDFloor Heavy Traffic is also suitable for aircraft hangars, automotive repair facilities, and garage floors. It is available in gloss and satin finishes. The mix (1.5 gals) will cover approximately 400 square 3 mils thick. (DO NOT APPLY ANY THICKER THAN 5 MILS IN ONE COAT). Do not allow this product to puddle. 2. BOLDFloor Commercial Duty Topcoat. This is the hardest and most durable Topcoat BOLDStone sells. This is the product that we recommend for this type of project. The mix (1.25 gals) will cover approximately 250 square 8 mils thick. (DO NOT APPLY ANY THICKER THAN 8 MILS IN ONE COAT). Do not allow this product to puddle. Multiple coats can achieve a smoother finish, however, the first coat needs to be tacky before a second coat is applied. If the desired look is closer to a polished floor, then either apply several coats of the Commercial Duty topcoat or use our High Build product below. 3. BOLDFloor High Build Topcoat. BOLDFloor High Build Topcoat is the product to use if a smooth polished floor look is desired and hot or heavy vehicles or equipment will not be sitting on the surface very long. (Caution: This type of floor can be very slick with a very low co-efficient of friction. This is similar to all epoxy floor coatings without the aluminum oxide chip topping). This mix (2.95 gals) will cover approximately 150 square 32 mils thick. Multiple coats can achieve a smoother finish if desired. NOTE: BOLDFloor High Build Topcoat is not recommended for this type of application because the heat and weight of vehicles and some equipment could indent the topcoat if it is applied thicker than 16 mils. D. Drying Time. (Time to dry between coats, foot traffic and vehicle traffic) The drying time for BOLDFloor Topcoats is dependent on the temperature, humidity, and application thickness. On average, the BOLDFloor Topcoat should be dry enough to walk on (using clean dry socks) to apply the second coat, if needed or desired, within 2 hours of application if the temperature is 70 o F and 55% RH. However, it is advised to test the surface in an inconspicuous area for dryness. To test, press your thumb into the topcoat (on the last area applied) after waiting 2 hours. If no fingerprints are left in the topcoat, you may begin applying the additional coat. Cooler and/or more humid conditions will require a longer cure time. Temperatures should remain above 41 F (5 C) during the cure period. The BOLDFloor finish must be allowed to fully cure before being exposed to rain or freezing temperatures. Once all coats have been applied, allow 16 to 24 hours before even light foot traffic is allowed across floor. The floor should be fully cured anywhere from 3 to 7 days, (depending on temperature, humidity, total thickness of application, and proper ventilation). 12

13 V. Clean Up All BOLDStone products, except the BOLDFloor Commercial Duty Topcoat, are water based. So, equipment and surfaces that were inadvertently sprayed can be cleaned with water before the products dry. The BOLDFloor Commercial Duty Topcoat is solvent based. Therefore, any equipment or surfaces that were inadvertently sprayed can be cleaned by acetone. Even though BOLDStone s BOLDFloor High Build Topcoat is water based, since it is an epoxy, xylol will make clean up easier. Disposal of any excess BOLDStone material should be done according to local and/or federal codes.
