5 DETERMINING TRAY STARTING POINT One of the advantages of the Thin Brick system is that you can start tray installation at any point on the wall. The steel holding trays may be installed from the bottom working up a wall or from the top working down the wall. The key considerations in finding a starting point are: Finding a low starting point that will allow you to easily keep the trays level. Determining how close to ground level you want to install trays. Analyzing all openings and determining a starting point that will minimize course adjustments. Finding a point that allows for easy chalk line markings. MARKING THE LOCATION OF THE FIRST STEEL HOLDING TRAY Once you have determined a starting point, you need to take measurements to assure that the trays are installed level and that trays will align at each corner. The easiest way to determine that the trays are installed level is to measure the distance from your starting point up to the building s soffit. Repeat this process with each framed opening until all have been measured. Trays that intersect at all corners must align or the thin brick corner units will not fit properly. MARKING VERTICAL COURSING LINES Thin Brick steel holding trays are 3.20 in height and 5 trays will course every 16 when installed snugly against each other. This is the ideal condition to maintain the optimum joint size and spacing. There will be times when you will spread the trays out slightly in order to adjust coursing to meet certain conditions, such as to meet the top of windows and doors with a full tile to avoid cuts and increase speed of installation.. The trays should never be separated more than 1/8 apart from their fully seated (snuggly fit together) normal installed condition FINDING AND MARKING WALL STUDS Prior to installing trays, it is helpful to locate and mark the location of wall studs. Marking the stud locations will speed up installation and prevent fasteners from being incorrectly installed in the exterior sheathing. 5

6 1. INTRODUCTION FAÇADES BRICK TRAY SIZES Brick trays are available in 12 foot lengths. When installing trays along a wall section that is longer than 12 feet, it is important to stagger the tray joints and maintain a minimum 16 offset in joint placement between adjacent trays (see Figure 1.1). Use the appropriate fastener and install a fastener at every KarrierRail along the length of each tray. Fig. 1.1 Continuous KarrierRail 16 Joints are located between KarrierRail Minimum one KarrierRail offset or 16 IMPORTANT NOTE It is important to check the entire length of every tray to be sure the trays are positioned correctly. If they are not positioned correctly, you may have to remove trays, which can cause hidden damage to the building. TRAY PLACEMENT IMPORTANT NOTE Joints between tray ends must always occur between two studs. Never attempt to join two tray ends at the same stud. Always maintain 1/8 gap between tray ends. 1/8 1/8 6

7 2. INSTALLATION AT BASE AND CORNER INSTALLING THE FIRST TRAY Align your first tray at the proper starting place. Using a screw gun, insert a fastener through the steel holding tray and into the closest stud. Tighten the screw until the screw head is flush with the tray surface. Before inserting another screw, check the alignment of the tray and make sure that it is aligned with the chalk line. Insert another screw through the steel holding tray and into the closest stud at the opposite end of the tray from the starting point. Check the alignment of the tray and finish inserting screws into every stud along the length of the tray. COMPLETING TRAY INSTALLATION AND JOINT STAGGERING You may install additional trays either moving up or down the wall depending on your starting point. The designed tray spacing is 3.2 which requires the flanges to be firmly seated and the backs of the trays touching each other. However, when you need to spread the trays slightly to meet certain conditions, the trays must never be spaced at more than 1/8 apart per course from their fully seated normal install condition. Make certain that every tray flange is firmly seated into the next tray. Use chalk lines and check for level as you install additional trays. Make certain that trays will meet precisely at all corners with the trays on the adjacent wall or corner tile will not work. STARTING WITH A THIN BRICK CORNER It is recommended to begin brick installation in the two steel holding trays immediately below the lowest window opening. If you are starting on a wall that requires corner units, begin the brick installation by inserting a corner brick (using the long end) at one end of the wall. Move to the other end of the wall and insert another corner. Begin filling the first tray completely with thin bricks, allowing 3/8-1/2 vertical head joints between all bricks, whichever works best for windows, doors and wall length. PROPER INSTALLATION OF THIN BRICK Each thin brick contains grooves on each long edg pered. Always install thin bricks with the tapered edge down. Insert a brick into the tray until the top groove fits into the top tray edge. Using a white rubber mallet, tap the bottom of the brick in an upward motion until the tray bottom edge snaps into the brick s bottom groove. TIP When installing trays, use the minimum amount of fasteners needed to hold the tray in place until all rails in that section have been placed. This will make adjusting the tray easier if necessary. 7

8 2. INSTALLATION AT BASE AND CORNER BRICK TRAY INSTALLATION You may install additional brick support trays, either moving up or down the wall depending on your starting point. The design tray spacing is 3.2 which requires the flanges to be firmly seated and the backs of the trays touching each other. However, when you need to spread the trays slightly to meet certain conditions, the trays must never be spaced more than 1/8 as shown in figure 2.1. NOTE When adjusting coursing by separating trays, 1/8 or less per course is recommended. 3/16 or more separation per course is not recommended. Use chalk lines and check for level as you install additional trays. Make certain that trays will meet precisely at all corners. Fig /8 maximum seperation 8

First, cut a piece of thin brick steel tray the same length as the width of the J-channel below the window or the bottom of the window frame (if J-channel was not used). Second, snap two Tru-Brix S6 sills into each end of the cut tray. Third, place the tray and sills directly below the bottom of the window frame. Slide the tray up until the top of each S6 sill is snug against the J-channel. If not using J-Channel, trim the top flange of the tray so the tray sits snugly against the bottom of the window frame or sill trim as shown above. Using your screw gun, apply fasteners until the tray is securely fastened. If J-channel was not used, apply a bead of highquality exterior sealant in the gap between the sill and the window frame. Next you must lay out the sills to determine if it is necessary to trim the sill bricks. Each sill measures 7 5/8 in length. After adding 3/8 for the mortar joint, an installed sill will measure 8. Re-measure the length of the tray you installed below the window. Divide this measurement by 8 to determine the quantity of sills required. It is important to trim the sills so that they are equal in length. NOTE The top leg of the tray can be trimmed off to allow a closer fit of sill brick to trim. Finally, remove the two sills and install fasteners at each end of the tray. 11

16 3. MORTAR PRE-MORTARING CHECKLIST Inspect all wall areas for any defects prior to starting the grouting process. Remove and replace any off color or broken bricks before grouting. Read and follow instructions. Mortar is available in 50lb bags which will cover approximately 27 square feet for modular bricks and approximately 32 square feet when used in conjunction with modular oversized bricks. CAUTION Useful life of mixed mortar is only 30 to 40 minutes. If you cannot use the entire batch in the alloted time, mix half batches of mortar. MORTAR MIXING INSTRUCTIONS Pour 6 quarts of water into a 5 gallon bucket. Pour 3/4 of a 50 lb bag of mortar into the bucket with 6 quarts of water. Mix thoroughly. Add the remaining dry mortar from the 50 lb bag into the 5 gallon bucket. Mix again until the right consistency is reached. Do not add more water if seems too dry - keep mixing it will get wetter. If water absolutely needs to be added, do so in very small amounts at a time. Re-temper (re-mix) every minutes or as necessary until mortar is used up. Be sure to only add a little bit of water when re-tempering. Work in a methodical fashion, 6-10 brick across at the bottom course and move up 1 course at time so when it s time to strike the mortar you begin at the same place you first put the mortar into the wall. Overfill the joint or there won t be enough mortar to strike. Don t strike too early or you will have a messy smeared wall. The mortar needs to setup to the point that it strikes well and the excess falls right off. CAUTION Be careful not to add too much water, which will make the mortar too thin. Soupy mortar may slump during application resulting in walls that will require cleaning after grouting. 16

17 PREPARING THE MORTAR POINTING GUN Once assembled, lightly spray WD40 or a similar lubricant into the gun s tube. Also lightly coat the rubber gasket attached to the gun s plunger. Using the scooper, fill the pointing gun cartridge completely with mortar. Begin filling the joints by starting with the vertical head joints. Work carefully to prevent excess mortar from dripping on the brick faces. After two rows of vertical head joints, begin filling the adjacent horizontal bed joints. CAUTION Make sure that all head joints are completely filled. If some joints are not completely filled, take mortar from a joint that has been overfilled. Simply scrape the excess off with the striking tool and apply the mortar to the joint that is underfilled. HINT If you spill mortar on to the faces of the bricks, wait until striking is completed before trying to remove the mortar droppings. If you immediately try to remove the droppings, the mortar will smear and cleaning may be required when finished grouting. 17
