229AR Elastomeric is available in Brush, Spray, Trowel or Caulk Grades. Brush Grade is recommended for use as a roof coating on BUR, SBS and APP modified bitumen membrane roofing smooth or granulated, concrete and spray polyurethane foam roofing as a protective coating. Trowel Grade can be used to make repairs on BUR, SBS and APP modified bitumen membranes, concrete, spray polyurethane foam roofs, metal roofs, and inactive coal tar roofs. Caulk Grade is ideal for sealing on asphalt roof surfaces as well as masonry, metal, spray polyurethane foam, wood, stone, brick and concrete.

SURFACE PREPARATION:
Surfaces must be clean, dry and free from oil, grease, release agents, laitance, dirt, dust and debris. All cracks and holes should be filled with 229AR Elastomeric Trowel Grade prior to surface coating.

APPLICATION:
229AR Elastomeric Brush Grade should be mechanically mixed thoroughly, prior to application. For vertical applications use only 229AR Elastomeric Trowel Grade.

Trowel Grade:
Apply to either vertical or horizontal surfaces using a smooth edge trowel. Coverage will vary depending on the desired thickness. To achieve a 1/16” thickness apply at the rate of 4 gallons per 100 sq. ft.; 1/8” thickness apply at the rate of 8 gallons per 100 sq. ft.; ¼” thickness apply in two coats at the rate of 8 gallons per 100 sq. ft. per coat.

Brush Grade:
Mix thoroughly just prior to using. Apply to horizontal roof surfaces with a fiber roof brush at the rate of 3 to 4 gallons per 100 sq. ft. Coverage will vary depending on the irregularity and porosity of the roof surface.

Caulk Grade:
‍Apply directly in and over cracks using a standard caulking gun. An application rate of ¼” x ¼” bead of caulk will yield approximately 75 linear feet per 30 oz. caulking tube. Coverage may vary depending on desired thickness and surface being caulked.

Do not use near open flame. Avoid breathing solvent fumes and prolonged contact with skin. Do not take internally. If swallowed, do not induce vomiting. Call a physician immediately. Keep out of reach of children. Store in a heated room and keep container covered when not in use. Do not thin. Dispose of in an environmentally safe manner. Cover air intakes during application and while drying. For exterior use only. Cold-process systems and coatings, either emulsion or solvent-based, should only be installed on decks with positive drainage. Per NRCA (National Roofing Contractors Association), “The criteria for judging proper slope for drainage is that there be no evidence of standing water on a deck 48 hours after it stops raining.”

Tools and other equipment should be thoroughly cleaned with 709 Karna-Klean. Mineral spirits or similar solvent may also be used, taking necessary precautions when handling combustible material.
