FOLLOW THESE SIMPLE APPLICATION STEPS
Clean and Prep:
Before pressure washing apply and brush out stains using Cleaner/Prep manufactured by Rainguard and available here on our website. Ensure the surface is clean and “bone dry”, thus allowing the sealer to absorb into the surface.

Application:
For a proper application, use a hand pumped garden sprayer. Apply 1 (one) heavy saturation coat to ensure the product can penetrate deep into the surface, sealing the pores or capillaries. Once the 1st coat is dry to the touch apply the recommended 2nd saturation coat to ensure best results. Once the 2nd coat is completely dry you can now put any decor, furniture etc. back on the treated surface. IMPORTANT: Avoid letting any water to come in contact with your newly sealed surface for 24 hours. After full cure time is achieved (approximately 4-5 days) you can expect the full beading effect.

Wait to test water repellency after the full chemical cure period. To conduct a test, simply drip some water in a few places where you have sealed the surface, if the drips make the surface darken, this is an indication that it is still absorbing, meaning you need to apply another coating. (more common with older surfaces)

Vertical Surfaces:
Allow product to drip heavily before moving onto the next spot. Heavily saturate the surface maintaining at least a 6-inch drip or run down.

Horizontal Surfaces:
Apply the product until it starts to pool up slightly. You will know enough was applied in any given spot when the product starts to pool (puddle) up with a milky-white color. The puddling will dissipate slowly into the pores so there is no need to back roll or brush them out.

Clean-Up:
Clean-up is a breeze thanks to our water based formula. Simply rinse out equipment with fresh water after application until it runs clear. Any undesired over-spray on windows or glass can be immediately wiped off. If the product has already dried it can be cleaned off quickly with a rag, warm water, and a mild soap.

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.
