Topcoat® 322 White Elastomeric Coating



Elastomeric Roof Coating

Topcoat® 322 White Elastomeric Coating is a styrene acrylic-based roof coating that forms a seamless and flexible layer of protection for your roof. This coating is designed to seal and dramatically reduce the surface temperatures and to resist heat absorption and cracking due to thermal shock. Topcoat® 322 White Elastomeric Coating is an ENERGY STAR®Qualified Reflective Product which will help in reducing interior building temperatures. Formulated to provide a tough, durable weather resistant coating, this flexible fast drying elastomeric coating adheres readily to most roofing substrates and is designed to protect the roof substrate from the damaging effects of the sun’s heat and ultra violet radiation.

  • ENERGY STAR®Qualified Reflectivity can dramatically decrease interior building temperatures
  • Meets the stringent standards for solar reflectance and thermal emittance set by the California Energy Commission for a cool roof
  • Offers high tensile strength and elongation, and is virtually undamaged by extended exposure to solar ultraviolet energy
  • Low VOC, non-flammable and presents minimal hazard to the applicator or the environment
  • Provides a protective and reflective finish that will keep the sun’s damaging rays from prematurely aging your roof, while keeping the substrate temperatures substantially lower to alleviate stress on the membrane


Uses

Topcoat® 322 White Elastomeric Coating is an ENERGY STAR®Qualified Reflective Product which will help in reducing interior building temperatures for:

  • Smooth surfaced asphalt built-up and modified bitumen membranes (aged for a minimum of 90 days)
  • Protection and restoration of aged roofs

Surface Preparation

All surfaces must be clean, dry and free from any foreign matter, such as oil, grease, dirt or debris that could inhibit the bonding capabilities of the coating. On existing roofs, inspect roof deck condition; moisture in old roof may require complete removal of existing roof. Check local building codes; local building codes may require complete removal of existing roof. Contact GAF Contractor Services for details on cutting out and repairing blisters, buckles and raised edges for a smooth surface. Check all flashings, edges, drains, valleys and vents and repair as needed. Use MATRIX™ 203 Plastic Roof Cement for repairs and follow can instructions. Repaired areas using roof cement must weather a minimum of 90 days.



Application

Application Rate:Typical application rate is 1 gallon per 100 square feet per coat. Typical applications require 2 coats. Application rate may vary with surface conditions and membranes used.

Application:Stir before application. Apply coating with roller, brush or sprayer, covering the surface at an even rate of 1 gallon per 100 square feet. For spray application, use a Graco 30:1 ratio pump or equivalent, capable of delivering 3-5 gallons a minute. Recommended method for application is by airless sprayer.

Installation Method:Spray: A Graco 45:1 pump or equivalent is recommended. Consult equipment manufacturer for optimum psi, spray tip size, length of hose and number of spray guns to achieve uniform coat. Brush: Apply smooth, heavy coat using parallel strokes for uniform coat. For maximum reflective surface, DO NOT OVER BRUSH. Roller: Apply smooth, heavy coat, using parallel strokes for uniform coat.

System Installations:See membrane manufacturer’s application instructions for use in roof systems.



Precautions

Compatibility & Limitations:BUR and MB surfaces must be aged for a minimum of 90 days. Do not use on extremely wet surfaces, directly over wood or on surfaces previously covered with coal tar products. Do not apply if there is a threat of rain within 24 hours. Do not use over coal tar or rubber membranes or over shingles of any kind.

Temperature Range:Apply only when temperatures are 45°F (5.5°C) and rising. Cold weather will cause product to stiffen, making application difficult. Store 24 hours at room temperature prior to application. Do not heat container or attempt to thin this product. Not recommended for application on substrates that exceed 120°F (48°C).

Storage/Handling: Topcoat® 322 White Elastomeric Coating should always be kept away from heat, open flame and any source of ignition. Observe normal safeguards for storing and handling of this product prior to and during application. Do not allow coating to freeze.

Important:Repair leaks promptly to avoid adverse effects, including, but not limited to, mold growth.



Clean Up

Keep containers covered when not in use. Clean equipment and over spray with soap and water. Clean hands with waterless hand cleaner or soap and water. Dried material should be removed with mineral spirits or biodegradable turpentine solvent.



Caution

Do NOT take Topcoat® 322 White Elastomeric Coating internally. If swallowed and patient is conscious, induce vomiting by giving two glasses of water and pressing down at back of throat. Never give anything by mouth to an unconscious person. Get medical attention immediately! Eye Contact – Rinse immediately with water for 15 minutes and seek medical advice. Personal Protection – Irritation may result from prolonged or repeated contact with skin. Wear chemical resistant gloves, protective goggles and protective clothing, if needed. Fire Protection – Topcoat® 322 White Elastomeric Coating should always be kept away from heat, open flame and any source of ignition. Waste Disposal – Empty containers must be disposed of in an approved landfill in accordance with local, state and federal regulations.
