Rainguard Water Sealers Brick Sealer, Penetrating Protection Against Rain and Moisture Damage, for All Brick and Mortar Surfaces, Silane/Siloxane Waterproofer, Natural Finish, Makes 5 Gallons

Worked great to protect my chimney for another year.

Repels water and the brick looks brighter almost a wet look. Easy to apply with sprayer.

EASY TO USE BUT DID NOT HAVE ENOUGH USE TIME TO DETERMINE WATER RESISTANCE. DESCRIPTION OF PRODUCT ON AMAZON IS CONFUSING. MAIN HEADING INDICATES ONE QUART BOTTLE OF CONCENTRATE MIXED WITH WATER TO MAKE ONE GALLON OF SOLUTION WHICH COVERS UP TO 150 SQUARE FEET. THE DESCRIPTION UNDER "CONCENTRATED FORMULATION" INDICATES THAT THE ONE QUART OF CONCDNTRATE IS TO BE MIXED WITH WATER TO MAKE TWO GALLONS OF SOLUTION WHICH COVERS UP TO 300 SQUARE FEET. ALSO, DESCRIPTION STATES THAT LIQUID IS YELLOW IN COLOR BUT IT IS WHITE.

It is an OK product. Results not very satisfactory. Hard to tell the effects after only a year.

I'm writing this review several months after applying this sealer. I installed a brick veneer backsplash behind my kitchen stove. This sealer was easy to apply, had a clear matte finish that didn't alter the brick or grout colors and thus far has kept moisture, water/cooking steam and food splatters from staining the brick. Very happy with this product!

Easy to mix.no measuring teaspoons of product.1 gallon of water to bottle of mix

Quick shipping, packed very well. Won’t know till next year on how well it works. Needs to go thru a winter of thawing and freezing.

This product is worthless, don't waste your money on it!Only gets a star so I could post review
