Efflorescence Blocker Protects Concrete & Masonry | Floors & Walls

Coverage rates will vary depending on substrate porosity and texture.

MIXING AND APPLICATION INSTRUCTIONS

Test Panel: Always apply material to a mock wall or test panel.  Test wall or actual surface area to determine acceptable color, surface porosity, application rates and methods before starting general application.

Surface Preparation: Before application, the surface should be clean and dry with no oils, dirt, debris, or minerals such as efflorescence, lime and calcium. These stains, along with others, will prevent proper penetration of Efflorescence Blocker to sufficiently seal for the warranty period. We recommend using our Restore’N’Prep product as a pre-treatment to clean masonry surfaces. Once clean, allow the surface to fully dry before sealing or applying a top-coat (See Restore-NPrep listing for details).

Vertical Surfaces: For vertical applications, do not allow the product to drip.

Horizontal Surfaces: For horizontal applications, do not allow the material to puddle up. Backroll any heavily pooling areas

Application:

1. Prepare surface by removing any current efflorescence using RainGuard Restore-NPrep. The surface must be prepped, clean, and dry before product is applied.

2. Allow the substrate to dry for 1-2 hours (depending on the weather) after cleaning.

3. Apply in a thin coat by using just enough material to wet the substrate. DO NOT apply in a flood coat. Applying too much material may cause the appearance of the coating to be hazy. Back roll any drips or pooling. DO NOT atomize.

Clean Up & Disposal: Clean up promptly with mild soap and water before product cures. Dispose of according to local, state and federal regulations.

PRODUCT STORAGE: The recommended storage temperature is approximately 22 °C (72 °F). Do not damage containers. Store in a dry place. Do not store for extended periods in direct sunlight. Protect containers from resin and moisture contamination

PRECAUTIONS & LIMITATIONS:

Use material in a well-ventilated area. Protect the work of other trades. Protect shrubbery and other plants with drop cloths. Protect automobiles and all other areas not to be coated from overspray. Remove overspray from any windows, automobiles, metal, etc. as soon as possible should it occur. To prevent permanent staining, clean spills or leaks in a timely manner. 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. All cracks should be pointed or caulked. All voids, beeholes, 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. Do not apply to surfaces if moisture content is greater than 25% as measured with an electronic moisture meter. Do not apply materials in climates where freezing temperatures have existed prior to application. Allow adequate time for surfaces to thaw. Establish that air, surface, and material temperatures are above 40°F (4.4°C) and at least 5°F above the dew point prior to painting. Do not apply at temperatures below 40°F when temperatures are expected to drop below 40°F within 48 hours of application. Do not apply if rain, snow, or lower temperatures are expected  within 48 hours. Do not apply if relative humidity is greater than 90%.
