Customer Questions & Answers

after two coats, do I have to prime or can I go straight to reg coat of paint?

I just painted two coats of Dry Lock this weekend on Cinder block walls in my basement. I would like to slap on a final coat of paint and move on to the next project but thought I had better check to see if a primer coat was required. The Dry Lock had some discoloring in areas of the wall.
Asked by: Ronn
Although I stop short of calling myself a professional, as a maintenance manager and former property inspector I am knowledgeable of and commonly read manufactures information. I am insulted by the former answer by the "professional" sales associate encouraging someone to buy a primer. If one reads the directions supplied by UGL a primer is not even mentioned. More importantly is the use of and etcher - if efflorescence is present - and a filling compound. Clearly the "professional" sales associate was just trying to unnecessarily add to a sale. It really makes a site look bad when an unknowing sales associates pass themselves off as professionals when they don't even read manufactures recommendations.

Would this work to seal a crack in basemet wall foundation where water is seeping in? And also on exterior foundation?

Asked by: Rakel
For a below grade basement wall of either brick, block or that has either of these and been coated with cement or paint, and has water seepage, when you plug one crack, hydrostatuc pressure from rain will simply push wstee through another weak area in the wall. I found that digging out all i vious cracks to remove loose material (especially the crack where the wall meets the floor, and using hydraulic cement as a parge or "skim" coat about 1/4" thick, stopped the seepage. I coated the area from the floor (and out from the wall @3") to a point @4 feet high. Hydraulic cement is sold at home depot and lows. Look for it in a bag, not the small tub.

Customer Reviews

1 gal. White Masonry Waterproofer is rated 3.2 out of 5 by 30.
Rated 5 out of 5 by from The Stuff is the Real Deal Wow, this stuff is great. You must apply it per the label ( scrub it in on the first round, make sure there is no paint). I was back and forth about using this. I called the company on three occasions as I couldn't make my mind up lol. I got right thru each time, no wait time, and I got the same gal Marissa each time. she was so helpful and convinced me that it is something I can do on it own and she gave me much peace of mind and took her time listening to me. I used two coats as suggested after a few days of prep, and no more musty smell and no more water! I can't see how this can get a bad review unless it was applied not following directions. Way to go Drylok! Amazing product!

I painted a cement water fountain with Drylok because the original finish was looking pretty bad. I prepped the was very, very clean and dry. I applied two coats, waiting 24 hours between each coat in 80+ degree, (July 2016) weather. Drylok was very easy to apply and very easy to clean up. The finished job looked beautiful! After 3 days, I filled the fountain with water and turned it on. Beautiful! I was delighted! In January, about 6 months later, it still looked great. HOWEVER...we received about 6 inches of snow, which then froze. The Drylok bubbled, buckled and chipped off, in huge chunks. I could take my fingers and easily pick it off. Today...9 months after painting my fountain with Drylok, I am using a power washer to remove the remaining Drylok. I wasted my time and money.

Rated 4 out of 5 by from This paint stops water! I have a 170 year old house in northern New England that for the past 10 years has had anywhere from a half an inch to 4 inches of water in the basement every spring, that is until recently. Two years ago I painted the brick wall in the back and all of the floors and even the stone walls of my basement with Dryloc and this spring the basement was finally dry. Maybe I was just lucky but I put it on concrete and brick that was quite damp (although clean) and have had zero issues with any pealing or bubbling of any kind. Have the paint associate mix it for you as its been on the shelf and is very think so its hard to get it mixed well at home. Great product that certainly worked for me!

Rated 5 out of 5 by from Better than I could have imagined! I had an unfinished basement room that leaked water through cracks in several places because the grade outside sloped towards the house and there wasn't much I could do, long story. Anyways, I thought I would have to dig up around the foundation and waterproof from the outside but after looking all over online I came across Drylok. It claimed to be able to waterproof from the inside so I decided to give it a try. I put 2 coats on approx 300 sq ft area(took 5.5 gallons) and it worked perfectly! I even flooded my foundation outside with water just to test it. No leaks at all! I've never taken the time to write a review before but I was so pleased with the results I just had to let others out there know that basement waterproofing can actually be done quickly and cheaply.

Rated 5 out of 5 by from A-W-S-O-M-E!!!!!!! Look, if you're looking to to stop a leak..... This is it! I literally had small geyser spurting out of my floor and my basement walls. Im a DIYer and had no funds to call a waterproofer. It was a nightmare to say the least. So, I took a chance and two coats, and two years later its still holding up. After hurricane Irene, Sandy gave us no flooding!! Or geysers! Thank goodness for this product!!!!

Rated 1 out of 5 by from Best Purchase Never Stinks to heck, extremely thick to apply, doesn't bond if your have serious enough water pressure, and now I have mold growing on my walls. It's a terrible product and I've found out now that locking water in my walls is actually softening the concrete blocks.
