Rain Guard Concrete Sealer 1 Gallon – Deep Penetrating Silane/Siloxane, Natural Finish

Protect without changing the look

Rain Guard Concrete Sealer forms an invisible barrier that helps concrete surfaces resist water, salt, oils, stains, and harsh weather. The silane/siloxane-based formula penetrates the pores of unpainted, unsealed concrete, helping prevent damage from freeze-thaw cycles, moisture, and efflorescence.

Ideal for indoor and outdoor use, it keeps driveways, garages, pool decks, patios, and other concrete surfaces looking natural with a flat, non-gloss finish. Drying time is quick—about an hour at 75 F (24 C)—and coverage is up to 200 sq ft per gallon, depending on porosity.

What makes it work

• Easy, practical application: designed for DIY use with common tools; no special equipment required.
• Deep penetration and water repellency: the formula fills pores to block absorption and create water beading.
• Long-lasting durability: resists stains, salt, and wear for years without peeling or yellowing.

For best results, apply two flood coats with a handheld pump sprayer. Cleanup is simple—wash with water and soap when finished. The water-based formula is free from strong odors and VOCs, making it safer for people, pets, and plants. Made in the USA, Rain Guard offers up to five years of protection under typical conditions.
