Customer Questions & Answers

Will this work on the inside of my basement - block walls are leaking water.

during extremely heavy rains, I noticed the block walls in my basement are leaking in various places. Will this stop the leaking into my basement?
Asked by: Anonymous
Sealkrete is designed to form a barrier from the exposed side of masonry. Therefore, it doesn't work as well if water/moisture is coming in through the product itself. A better product for your situation would be Drylok. Drylok is a paint-like substance that penetrates the pores of masonry or block and prevents water from penetrating from the other side. Sealkrete works in a similar fashion but Sealkrete doesn't have as many solids in it so it is better as a topical treatment meaning that you apply it to a surface to keep water from penetrating the surface rather than applying it to keep water from coming through he block wall. If the water penetrating the wall is significant, it may warrant exploring whether or not you should dig the dirt away from the wall and apply a sealer to the exterior of the basement wall. This is a big job so you may want to seek pricing from a contractor that specializes in exterior masonry sealers. If the water intrusion is minimal, Drylok should take care of it.

Can this be used to seal outside steps?

I had the outside steps re-done last summer - the bottom step complete and the others "patched". Was told the complete was sealed also. After the winter snow and ice, looks to be not so! The bottom step is flaking. Will this product seal the step and the spots that were repaired? I have spent so much on these steps since I bought the house in 2009, I thought I had solved the problem having one replaced and the others repaired.

If you want to save time/money & paint on a re-paint this beats rolling on a costly primer/sealer like S.W. & others sell. To apply it I use a cheap garden sprayer & a cigar roller to catch any runs on stucco houses in Fl. Couldn't be any easier. It goes on fast & clean-up is a breeze. It locks in the chalking You will still have After a thorough pressure washing. I can tell who used this or Not while P.W.ng The paint just flies off when not used. I'm 63 & have been using this for years . My jobs last. It goes on blueish white the consistency of skim milk but dries clear. If you get it on glass, no big deal it just wipes off W/A rag. Cleans up W/water. Missed a spot? When dry it scrapes off using a razor. You wouldn't paint over talcum powder & expect good adhesion. This solves ANY of that. Try it you won't go back.

Rated 5 out of 5 by from Saved my brick Over the course of the last few months, we've had very heavy rains which is very unusual this time of year for my region. The hard rain was hitting the 60 year old brick facade of my fireplace and bleeding through to our newly renovated living room. Wanting to keep the beautiful look of the brick, I searched high and low for a product that would keep the bricks natural appearance yet lock out any moisture. This product didn't disappoint! At first I was very apprehensive because of the consistency, it goes on a watery white (almost appears like skim milk) but once dry, forms a type of waterproof seal. Think of it like rain-x for masonry . It does leave a slight (very slight) shine to the brick-which was a concern of mine- however it actually restored the natural look and appears amazing. 2 coats is essential! Very highly recommend this product and will be purchasing more for other projects around our home.

The product is easy to apply and the clean-up of the sprayer with soap & water is a terrific dividend. Applied it to freshly laid pavers which soaked it up thirstily. Will be applying a second coat soon. Thanks for making a good product. ;-)

I had areas with hairline cracks, a few chunks out (patched), and one area that was sandy and crumbly. This product goes on thin, but hardens and seals patched areas and remarkably solidified the crumbling spots. I added (as suggested) 3-1/2 oz to the gallon of outdoor cement/foundation latex paint and the final result is remarkable! Solid coat of waterproof color and I am so pleased. Best choice I've made! Great product!

Rated 5 out of 5 by from Used on Old Barn Tin I used this product on old rusty barn tin that is being installed on the ceiling of my great room. Went on easy with blue tint which was great because I could see where it had already been applied. It dried clear and somewhere between a matte and satin finish. It did not darken or discolor any of the patina on the tin. It took some searching to find a product for this application and this did the job to perfection.

Rated 5 out of 5 by from Great Stuff Went on well, covered about 300 square ft dried in predicted time. I used it as a primer for a coat of epoxy paint washing new concrete wit tri-sodium- phosphate first. So far it's doing well. A better test will be in a year or two.
