Metacrylics® Acrylic WHITE Elastomeric Roof Coating

Printer-friendly version

DESCRIPTION: WHITE, water-based acrylic elastomeric coating. Non-volatile, highly adhesive, UV resistant, reflective, protective coating for almost any surface.

USES: For use as a reflective protective coating. When applied with Metacrylics Primer, Base, and Polyester fabric, this product is recommended for all roofs and decks. Other uses include exterior and below grade waterproofing. May be applied to wood, metal, glass, tile, concrete and stucco surfaces.

ACRYLIC WHITE: White color.

ZINC OXIDE: Metacrylics Acrylic White contains no zinc oxide. California Prop. 65 has identified zinc oxide as a hazardous material. No product manufactured by Metacrylics contains zinc oxide. This has been verified by independent testing by ICC-ES and UL Laboratories, our quality control agency.

WEATHERING: 2,000 hours weatherometer - no cracking, crazing, or erosion, slight chalking. ASTM D638

TEMPERATURE CYCLING AND PENETRATION: Tests conducted in accordance with the "Acceptance Criteria For Special Roofing Systems" as published by the International Conference of Building Officials (ICBO). Results: PASS. Samples averaged 1.626 before testing. Samples averaged 1.610 after being subjected to the Weatherometer. The change in thickness was less than 1%. Examination of the samples after testing showed no evidence of tearing or cracking of the protective coating. *Temperature Cycling and Penetration Testing: 25 continuous cycles of 1 hour of water exposure at room temperature prior to 6 hours at -40o F, 2 hours at 70o F, 14 hours at 180o F and 1 hour at 70o F. Spray nozzles delivered 6 in. of water per hour at a temperature of 40o F to 60o F. At the conclusion of the 25 cycles the specimens were examined.

FLASH POINT: No flash at 200° F (water-based). ASTM 1310, Tag Open Cup

TOXICITY: Not for use with potable water

PARTICLE CHARGE: Negative

WEIGHT: 12.1 lbs./gallon

VOC (Volatile Organic Content): 27.5 grams/liter

SOLIDS CONTENT (by weight): 68.4%

SURFACE PREPARATION: Surfaces should be clean, dry, free of dust, dirt and oily residues. Remove loose rust from metal, and wipe new galvanized metal with acidic acid solution prior to application. Metacrylics Primer is recommended for all surfaces. New concrete must be fully cured. New glazed asphalt and torch down single-ply assemblies should wait 6 months or more before application.

SPRAY APPLICATION and COVERAGE RATES: Apply 2 coats of ACRYLIC WHITE @ 2 gallons/100 sq. ft. per application (total 4 gallons/100 sq.ft.) using a .035 - .039 spray tip. Allow 12-24 hours between applications. Hints: Don't spray on windy days! Use barricades around the job. Visqueen all skylights, etc. not to be coated. Be sure to have 1/2 a barrel of water to flush the pump and hose when finished. Be sure to have extra tips and TSL Throat Seal Liquid. Carefully pour a 1/4" layer of water over the drum of Acrylic ACRYLIC WHITE to prevent skinning over.

ROLLER APPLICATION and COVERAGE RATES: Apply 3 coats @ 1-1/3 gals /100 sq. ft. per application (total of 4 gals/100 sq. ft.) allow 12-24 hrs between applications.

NON-SKID APPLICATION: Sand may be gently broadcasted over the wet acrylic WHITE, or mix 1/2 gallon of #30 mesh sand, rubber granules, etc. with 2-1/2 gallons of ACRYLIC WHITE using a stick or electric drill with mixing paddle, add more or less sand to desired consistency. Apply with a texture roller or texture gun.

HINTS: Allow 24 hours drying time or dry enough to walk on. Cold temperatures slow down the drying times. Start early, stop early! Application in hot temperatures should be avoided or blistering of the coating may occur. If any Acrylic WHITE is left over, apply additional coats until all product is used. Four gallons per 100 sq. ft. is necessary to prevent delamination in ponding areas and to maintain superior performance under UV and freezing conditions.

CLEAN-UP: Clean tools and equipment with water . Cured material may be removed with amylacetate, hand cleaner, or lacquer thinner. Do not use these materials (except hand cleaner) on bare skin.

THINNING: Thin with water if necessary.

STORAGE: Store in areas where temperature remains above 40oF. Prior to use agitate for 2-3 minutes by hand or machine. Reseal opened containers. If contents skin, remove skin, agitate, use immediately. If the product has been stored for a months (or years), remove any surface skin that may have developed, stir, and immediately use.

IMPORTANT APPLICATION INFORMATION:

DO NOT APPLY if rain or freezing weather is imminent within 24 hours following application, or during fog or drizzle. This product is water-based and could wash off if not fully cured.

PROTECT materials from freezing and extreme heat.

DO NOT APPLY when temperatures are consistently below 40o F. The Acrylic Base dries slowly when temperatures are below 55o F. Areas shaded from sunlight dry very slowly. Seventy-two hours or more may be required for proper curing.

DO NOT THIN or add solvents.

KEEP AWAY FROM CHILDREN.

CAUTION! Wet acrylic is extremely slippery when stepped on. Always use a safety rope on sloped surfaces.
