Rain Guard Water SealersSP-3005 Brick Sealer Ready to USE Covers up to 1000 Sq. Ft. 5 Gallon – Water Repellent Sealer, clear invisible

I applied these to my external brick stair case after finding black mold form in my closet behind it. I simply used a spray bottle by hand. It worked great, easy to apply. After having this applied, whenever it rains, I compare my stairs to my neighbor and I definitely notice my brick stairs absorb less moisture from rain.The hardest part was the prep work, to remove all the algae and scum off the bricks and stair steps before applying. I didn't have a power washer, and did most of it with a brush attached to a drill.

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!

Bought it to seal out front porch brick stairs, it's been 2 years and still looking good, especially in the south with red dirt. Washes off dirt easier.

This worked great on my walls to help prevent efflorence. I also painted over this product then sprayed this more of the Rain Gaurd sealer over the paint again for double protection.

We used this to seal the bricks on our brick house, then we used it on our concrete areas, then decided to try it on our pavers...worked great on all.
