Customer Questions & Answers

Applied to concrete block wall?

I'm looking to raise the soil level around my house by 1' and need something to water proof so the moisture won't get into the block. Can this be applied directly to the block or do I need to spread cement over the block first? Upon research and other products say to spread a thin later of portland cement over the block before applying. Also, will this product bend and stretch with hairline cracks? Lastly, what's the consistency of the product? Is it like water or more like a tar? Thanks!
Asked by: Rick12
You can, and in my opinion should, apply this directly to the block wall. Portland if the wall isn't preped right will peel and crack with cold weather. With this you merely have to rinse and scrub the wall with a stiff broom then rinse and let dry thoroughly. The product is more a tar consistency, a bit thicker than driveway sealer. It is a little flexible when dry and can handle existing hairlines. If you have a deep concern you can put roofing caulk in the hairlines and then apply the product over the top. Apply the product right up to the siding for a uniform look and full protection of the foundation.

What happens if this product is used in the interior of the basement walls?

Will the odor be toxic for resident? Is this going to create other problems?
Asked by: CuriousPerson
I'm worried! We already used this on a garage floor that is going to be converted to a living space. It has been only a few days and the odor is strong and I know that it is not fully cured. However, how do I get this off now and if I cannot get it off, what can I seal it with so that it does not continue to give off odor?

Coverage for concrete block walls???

I have raw, concrete block foundation....want to use this before back filling....trying to plan number of buckets/cost. How to apply...Brush or whatever else is recommended. Area is 8 ft high and foundation is 24'x32'....a little less if I only use coating below grade.
Asked by: Bobby
The product says 100 sq ft per gallon, figure on 80. You have 24x8x2 or about 430 sq ft plus 32x8x2 or 580 sq ft for a total coverage area of about 1000 sq feet. Looks like about 13 gallons or 3 buckets is about what you need. You don't want to run out mid-wall or try and stretch it, get it on in 1 continuous coating. Coat right up to the siding, protect all the masonry surfaces. Pre coating rinse the wall down and scrub it with a bristled push broom to pull out any dirt and loose particles from the blocks, rinse it down again and let it dry thoroughly, at least 2 days. If its going to rain protect it with plastic and pull the plastic away when its not going to rain. Use a 3 tuft roofing brush, slather it on and don't try to make it too thin, you want it nice and coated but not runny thick. The dry wall will suck in the thinned material and really lock in the pores. Make it nice and waterproof so it doesn't chill, crack, and heave. I'd put at least 2" of EPS foam against the coating when dry before you backfill, keep the cold away from the wall and it will pay back with lower heating bills in under 3 years for the extra material. Your basement will be dry and warm.

(Home inspectors request) painted on with brush... very thin ... but turned out to be a good thing... Painted with brush but didn't want to get brush dirty so I left the bottom 2 inches bare and was going back to "touch up" when finished..... when I got done and back to the beginning the coating had ran ..... and puddled against the ground,,,, wooohoooo I didn't have to touch up.... waited 3 days to "dry" and back filled... In cool weather takes a really long time to dry....

Rated 5 out of 5 by from Good Product I used this product to waterproof my basement wall from the exterior. First I dug all the way down untill I reached the footing base bottom then I cleaned the footing wall very well then applied two coats of this product. It did work very well. We had I little of humidity in our basement but thanks to this product the problem was solve.

Rated 5 out of 5 by from I ordered online and the product came earlier than expected.... I ordered online and the product came earlier than expected. Worked great and application was easy. The warmer the coating the thinner and easier it was to apply. If it is going to be cold out when applying I suggest putting it near a heating vent the night before or soaking in hot water for an hour

Rated 5 out of 5 by from Great product - easy to use Due to schedules I decided to coat my foundation with this rather than wait on the waterproofing sub's schedule. It was about 25 deg F and this still went on good. As it got cold it congealed and became more difficult so try and keep it warm. WARNING* it doesn't cover 100 sq ft per gallon as web site states! You can zoom in on the picture of the bucket and see it claimed to take 1.5 - 2 gallons per 100 sq ft. It took me about twice as much as originally estimated. I just used a paint roller and it went pretty fast while it was warm. I also found a tar and asphalt remover at the "L" store by Black Jack that was amazing at cleaning it off skin & clothes.

Rated 5 out of 5 by from Great Product I just used this to coat my foundation. after 50 years the original coating was no more. I mixed it thoroughly but it didn't change the consistence... it appeared it never separated. on the can it says not to apply if rain is threatening within 24 hours. I could not find a drying time on it. it took roughly 2-4 hours to become tacky and about 6-8 hours before it was dry. I Let it sit overnight anyway until I started the back fill
