## Questions & Answers

**Q: Is this for interior only?**
A: the description by the drylok company says that drylok can be used on interior or exterior, and that includes the latex based product, as well as the "extreme drylok."

**Q: Can this be used on basement concrete floors?**
A: We used it on basement floors and walls.

**Q: Can this be used  on  a plaster wall in a windowless bathroom?**
A: I used it on basement walls where there were no windows and it worked great

**Q: What does "2 pack" mean?**
A: I thought it meant 2 gallons, but they only shipped me one and half of it leaked into the shipping box despite a few extra little clamps they put on it. When I wrote they said 2 pack was an error, it is just one gallon and they refunded my money entirely due to one sent leaking

## Customer Reviews

### ⭐⭐⭐⭐⭐ Cures rock solid! Great product
*by J***O on March 7, 2017*

I did my exterior walls I my basement with this prior to finishing the rooms. I followed the directions except I used phosphoric acid to etch the walls instead of sulfuric acid or the dry lok brand etch. Used a garden sprayer to apply acid per phosphoric prep and etch directions and then rinsed with fresh water with a garden sprayer. Let dry for a day or two then painted 2 thick coats. Get the biggest nap roller you can find and slop it all over. Then take a cheap brush and fill in any pinholes after the paint flashes for about 30 mins. When all the pin holes are filled after several hours I applied another thick coat. After about two days this paint hardened up like concrete. I feel confident it will last a long time and provide a good level of water proofing and vapor barrier on my exterior sub level foundation blocks.

### ⭐ Don’t waste your money
*by M***Y on October 1, 2024*

I purchased this in February, today I finally decided to tackle my project, opened the can and saw this! I can barely get the stir stick in there. It’s chunky and separated. Nothing I can do with this. I’m hoping to get a replacement or my money back even though it’s outside of return time. I’ve never had this happen and I hope the seller makes this right.

### ⭐⭐⭐⭐⭐ excellent stuff
*by J***H on April 28, 2014*

I use this on an old shower at my camp. It waterproofs the entire shower stall, provides a skid free surface. Seems to inhibit mold and mildew. I give it a fresh coat about once a year and that's it. Great stuff.
