1 Interior System Evaluation 9.2 INT 9.2 PLASTER AND GYPSUM BOARD (GYPSUM WALLBOARD, DRYWALL, SHEET ROCK TYPE MATERIAL, & TEXTURE FINISHES, ETC.) The Substrate (i.e. surface) Plaster is a hard, gypsum based material found in many older homes and in some new custom designed buildings and restorations. A heavy base or ground coat is applied to wood or metal lathe attached to wall studs, and then smooth finishing plaster is troweled over top. In many new plaster applications, a gypsum cored, paper coated board is used instead of traditional wood lathe. This reduces the amount of base coat by about 40%. The method of application of finishing plaster can be varied to obtain a surface that can be smooth to rough in texture (e.g. Trowel - for a smooth surface; Floated or Sand Float finish - low stipple texture; Spray texture finish - smooth to moderately rough spatter texture; and textured finish - low to rough texture with a wide variety of patterns). Drywall panels ( gyproc, sheet rock, gypsum board, etc.) are the most common interior wall surfacing material. These are constructed of a gypsum-based core with a paper coating on all sides. Special purpose panels for fire resistance, damp proofing, and strength, use variations in the core and surfacing material. These panels are attached to vertical framing studs by either galvanized spiral shanked nails, or coated screws, then the seams between the panels are supported with a paper or fiber mesh tape, and filled with a plaster-like joint filler. A uniform painted finish cannot be obtained unless the filler is properly finished. Small defects, such as pinholes, ridging and fiber-lift, become very apparent after painting. Deep and dark colors should be avoided in high traffic areas on both substrates, as they are prone to marking.

LIGHT INDUSTRIAL COATING (Gloss/Sheen as Specified) INSTITUTIONAL LOW ODOR / VOC (Gloss/Sheen as Specified) INT 9.2A LATEX (OVER LATEX SEALER) Conventional Latex is a standard performance latex system, which provides suitable performance for residential use and light use areas in commercial and industrial installations such as offices and meeting rooms. Latex finish systems are often used on plaster and gypsum board subjected to a low to moderate amount of cleaning or abrasion for residential, light industrial (e.g. warehouse), and commercial buildings. The detergent and abrasion resistance is not as good as the alkyd system, but the color retention and resistance to yellowing is better. These systems offer a range of gloss finishes for different applications. The low sheen of the flat finish assists in improving the uniformity of slightly rough surfaces. Semi-gloss and gloss finishes are often used for accent striping or signage and/or for smoother surfaces. They are also helpful in reducing dirt and dust accumulation and are easily cleaned, but will accentuate the surface roughness. System Finish Gloss Levels -G1 MPI Gloss Level 1 Flat or matte Mainly used: - Flat paints are widely used on large, smooth, or textured wall surfaces. Pros: - Very easy to touch-up. Minimizes visibility of surface imperfections Cons:- Easily marked and stained. Not recommended for surfaces exposed to constant contact, since burnishing and dirt pick-up would be excessive. -G2 MPI Gloss Level 2 Low Sheen like velvet cloth Widely used on wall surfaces such as offices and other low traffic areas. Pros: - Ease of touch-up, uniform appearance, marks less than Level 1 Cons:- Marks easier and is less washable than Level 3 -G3 MPI Gloss Level 3 like an egg s shell Provides a balance of washability and durability while avoiding an overly glossy appearance. Pros: - Washability Cons:- Shows substrate defects -G4 MPI Gloss Level 4 like satin cloth Provides a higher level of durability, but sheen accents surface defects. Pros: - Quite washable, etc. Cons:- Shows substrate defects, and reflects light somewhat -G5 MPI Gloss Level 5 Semi-Gloss Principal uses:- where washability and abrasion resistance properties are most important Pros: - Resistant to stains and dirt retention Cons:- Difficult to touch up and shows substrate defects. -G6 MPI Gloss Level 6 - Gloss Principal uses:- Rarely used, except on smooth surfaces. Pros: - Ease of clean up (i.e. washability) and abrasion resistance Cons:- Highly light reflective and shows all substrate defects. Very difficult to touch-up

2 INT 9.2B HIGH PERFORMANCE ARCHITECTURAL LATEX High Performance Architectural Latex is a high performance system, which provides a significant benefit in the areas of scrub resistance, resistance to marking and burnishing, and removal of stains and marks from the surface. It provides suitable performance for use in commercial and institutional uses such as schools, public buildings, hospitals, etc. It provides increased washability compared to conventional latex products. They also provide increased resistance to staining, and ease of soil removal. The low and intermediate levels of gloss possess much better resistance to burnishing than conventional latex products. These systems provide almost equivalent performance to alkyds, but without the objectionable odor and with a greater friendliness to the environment. However, they are more sensitive to cleaners containing strong solvents than are the alkyd systems. System Finish Gloss Levels -G2 MPI Gloss Level 2 Low Sheen like velvet cloth Used on surfaces where greater durability and stain resistance than conventional latex is desired. Pros: - Ease of touch-up, uniform appearance, marks less than Gloss Level 1 (G1) Cons:- Marks easier and is less washable than Level 3 -G3 MPI Gloss Level 3 like an egg s shell Common usage in corridors and hallways Pros: - Washability. Provides a higher level of durability than Gloss Level 2 (G2) Cons:- Shows substrate defects -G4 MPI Gloss Level 4 like satin cloth Often used in high use corridors, but not as reflective as Semi-Gloss Pros: - Quite washable, etc. Cons:- Shows substrate defects, and reflects light somewhat. Difficult to touch up. -G5 MPI Gloss Level 5 Semi-Gloss Uses:- where washability, abrasion resistance and stain removal properties are most important Pros: - Resistant to stains and dirt retention Cons:- Difficult to touch up INT 9.2C ALKYD (OVER LATEX SEALER) This system is a general-purpose system for residential and commercial applications, where moderate chemical and good physical resistance properties are required. Available in glosses ranging from eggshell to gloss. Gloss Level 3 is often used in areas not exposed to repeated contact from cleaning, as this finish can show marking, particularly in deep or bright tinted colors. For high traffic areas subjected to repeated contact, or requiring regular cleaning, semi-gloss and gloss finishes are often used. These have better stain, marking and abrasion resistance than the flat or eggshell finishes. The alkyd has better water and detergent resistance than the latex (INT 9.2A), and would be preferred in higher traffic locations requiring repeated cleaning. System Finish Gloss Levels -G1 MPI Gloss Level 1 Flat or matte Mainly used: - where resistance to abrasion is not a requirement. Pros: - Very easy to touch-up and does not accentuate surface defects Cons:- Easily marked and stained -G3 MPI Gloss Level 3 like an egg s shell Common usage walls, trim, doors and frames a good balance between durability and reflectance Pros: - Washability Cons:- Shows substrate defects -G5 MPI Gloss Level 5 Semi-Gloss Principal uses:- where washability and abrasion resistance properties are most important Pros: - Resistant to stains and dirt retention Cons:- Difficult to touch up -G6 MPI Gloss Level 6 - Gloss Principal uses:- not often used except where washability and abrasion resistance properties are of utmost importance and where the surface is very smooth Pros: - Ease of clean up Cons:- Highly light reflective and shows all substrate defects. INT 9.2E INT 9.2F INT 9.2G EPOXY ( TILE LIKE ) EPOXY, W.B. ( TILE LIKE ) Some public buildings and commercial buildings, such as restaurants, shops, and bars, where high traffic is anticipated, and detergent and industrial strength cleansers will be used on gypsum wall board and plaster walls require durable finishes, such as INT 9.2E or INT 9.2F epoxy systems. Both systems have excellent resistance to abrasion and marking. The solvent based system has better water and chemical resistance than the waterborne epoxy, and is recommended for use in areas subjected to these materials frequently. Where solvent fumes are a concern during application, such as renovations or additions to occupied buildings, INT 9.2F waterborne epoxy is preferred. MULTICOLOR Effect finishes, such as INT 9.2H multicolor, are used in both residential and commercial applications. The premium version of system INT 9.2H uses a clear, protective finish as the last coat to improve the abrasion, detergent and dirt resistance. The premium version is generally recommended for areas exposed to moderate traffic and abrasion.

4 Interior System Preparation 9.2 INT 9.2 PLASTER AND GYPSUM BOARD Remove sand, dust, dirt, oil, grease, wax, silicone, glue, and all other foreign matter. Any defects apparent before, and after, the primer coat has been applied shall not be the responsibility of the Painting Contractor. The resulting surface must be made acceptable to the Painting Contractor before application of the finish coat(s). Drywall Defects Many defects in the drywall substrate cannot be seen until after the primer, and in some cases, the intermediate coat, have been applied. This condition in drywall is not connected with the quality of either the paint or its application. In addition, structural deficiencies in studding and improperly applied drywall can cause other problems such as "nail popping", ridging, pinholes, etc. Latex primer sealers are flat in appearance, and deficiencies can be hard to detect, particularly under low lighting conditions. However, when materials with a slight to high gloss are applied, the deficiencies in the drywall are very noticeable. At this point, the drywall contractor should be obligated to correct all remaining imperfections. Joint Fillers The Painting Contractor should be cautious when painting drywall (gypsum board), as some of the new type of joint fillers on the market may have an alkali content too high for normal paint coatings. Some lightweight joint fillers are so porous, they require refilling, different filler, or the addition of an extra coat of sealer or finish coating, none of which was called for in the painting specifications. This should not be the financial responsibility of the Painting Contractor. Only top line primer sealers with excellent sealing properties must be used. Recycled paper, often used to produce drywall facings, may require additional preparation such as careful sanding and the application of an additional coat of primer sealer to eliminate suction spots etc. Stain blocking or alkyd based sealers may be required to block the leaching of water soluble materials occasionally found in recycled paper. Plaster Newly applied plaster must cure a minimum of 30 days at 75 F (24 C). The surface must then be tested for alkalinity (See 1.2 ph Testing). Wash and neutralize high alkali surfaces where they occur. Any imperfection in the plaster must be corrected by the plaster trade. Large holes, cracks, joints and other visible imperfections, must be corrected before surfaces will be accepted. Paint should not be applied until repaired surfaces are completely dry. After the application of the primer coat, fill minimal cracks, holes and imperfections, and sand smooth to match adjoining surfaces. Moisture readings must be taken to assure that no more then 12% moisture is in the plaster at the time of the coatings application. Porous areas that show suction spots must be double primed. Environmental conditions before and during application and during drying should be as outlined (See 1.1 Environment). Where plaster hot spots or questionably cured plaster surfaces are encountered, the use of an alkali resistant sealer, such as MPI #3, is recommended.
