Chalky Wall Sealer and Clear Acrylic Primer

APPLICATION INSTRUCTIONS

WORKING WITH CONCENTRATES

FOLLOW THESE SIMPLE APPLICATION STEPS

Rainguard CHALKY WALL SEALER Shoul not be applied in windy weather. In hot weather, lightly dampen surfaces with clean fresh water to avoid premature or flash drying.

Bare Porous Vertical Surfaces Start first coat application at the top of the wall. Apply flood coat with a 6”- 8” rundown and back roll material into surface voids. Apply second coat when the first coat is dry.

New Vertical Concrete Surfaces

Material may be applied as soon as the forms are removed. Surfaces shall be clean and free of form oils and release agents. Start first coat application at the top of the wall. Apply saturation coat and back roll materials. Apply second coat when the first coat is dry.

Horizontal Concrete Surfaces Apply two saturation coats to damp concrete to assist the curing and hardening process. Apply one saturation coat to existing concrete surfaces to dustproof surfaces. Remove excess standing or ponding materials with a roller. Caution: CHALKY WALL SEALER is not recommended for application to surfaces subject to wheeled traffic.

Brick

Apply one saturation coat with run-down and back roll material. Apply second saturation coat when the first coat is dry.

Stucco/Plaster

May be applied to stucco or plaster during the curing process or when fully cured. Apply one saturation coat and back roll materials. Apply second coat when the first coat is dry.

Chalked Surfaces Thoroughly pressure wash. Apply one coat to chalked surfaces. Allow material to dry and check surface for chalking. Apply a second coat to surfaces as needed to control remaining surface chalk.

Wood

Surfaces shall be clean and bare. Pre-treat knots with a small amount of material. Apply a minimum of one saturation coats to wood surfaces. Apply second coat when the first coat is dry.

Masonry and Concrete

All surfaces to be coated shall be structurally sound, clean, and dry, free of laitance, accumulated dirt and grime, efflorescence, lime run, form oils and release agents, grease, mud, excess mor-tar, and mold and mildew, etc. Remove loose and peeling paint, excessive chalk, and other contaminants from surfaces. Dry brushing is the preferred method for cleaning surfaces prior to material application. However, chemical, mechanical, abrasive, or high-pressure water blasting may be used. Allow wet, cleaned surfaces to dry for 2-3 days before application of materials. EIFS and Other Surfaces Surfaces shall be structurally sound, clean, and dry. Clean EIFS surfaces following manufacturer’s recommendations.

PRECAUTIONS & LIMITATIONS

1. All surfaces to be coated should be clean of any dirt and grime, efflorescence, lime run, form oils and release agents, grease, mud, excess mortar, and mold and mildew, etc.

2. All cracks should be pointed or caulked. All voids, bee holes, masonry surface defects and openings such as conduits, pipes, drains, door frames, vents, air conditioner openings, electrical openings, control joints, or any dissimilar materials should be repaired using urethane or other approved patching.

STORAGE

Store materials in a well-protected area between 45° and 90°F. Avoid freezing temperatures, direct sunlight, and moisture. Keep away from heat sources.
