Rated 5 out of 5 by Sealing Concrete & Color on Simulated Brick I was looking for a product that would seal the concrete and color on simulated brick that would not take the chaulky like coloring that had been applied to the top surface of the concrete. An associate at Home Depot showed me Seal Krete and it seemed to fit the criteria. I tried It and it worked great! Just as the product described. It also helped rejuvinate the color. It is a watery thin sealer and messy to use, so a tip, you need to wear old cloths and cover any thing you don't wnat to get the sealer on. I would suggest a brush for small areas and a roller or sprayer for large areas. You can actually see this stuff soaking into the concrete and see, as well as feel, the difference once its dry. Great product and you can paint or stain over this product after it has dried properly. June 5, 2010
Rated 5 out of 5 by Stopped Chimney Leak I have a brick & mortar chimney that was leaking. When heavy rain would fall against the chimney, the water would seep through the mortar and leak into the attic. I sprayed 2 coats (the whole gallon) with a garden sprayer on the chimney portion above the roof and no more leaks. I plan to repeat this each spring. October 21, 2014
Rated 5 out of 5 by Excellent Product This is an excellent product for sealing vertical concrete walls that are aging and powdery. It also created a good surface for painting. April 10, 2012
Rated 5 out of 5 by Sealed leaking window frame I used this product to prevent moisture from seeping in a garage through a window frame. Has performed perfectly. The old mortar around the window no longer leaks. January 15, 2014
Rated 5 out of 5 by Seal-Krete Original Waterproofing This is my first time using this product. It brushes on nice and soaks into the mortar. Coats dry fairly quickly. Used this after tuck pointing the chimney and seems to work fine. Easy clean-up. Will update review as we go...... October 15, 2013
