## Questions & Answers

**Q: how uch will a 3 1/2 gal bucket cover?**
A: I usually use two and one half gallons in a 16 sq ft shower, but I put on five coats as we prep and waterproof the floors and walls.  I would say it woul cover 90 to 100 square ft adequately with multiple coats ( 2 )

**Q: Can I use this product on an interior plywood floor in a shed or is there something else that needs to be done first or after?**
A: I have only used this product behind tile covering. For flooring use, I don’t think this product would. It certainly will not work as well as just using a good floor paint that would adhere better than this product.

**Q: Can you apply this on sheet rock?**
A: You can but the purpose of using Laticrete is to waterproof, and so you should be using cement backerboard in any potentially "wet" area.  Backerboard should be used if you are tiling because sheetrock is not strong enough to hold tile.

**Q: what's the shelf life? Do I have to use it up quickly, or will it keep for couple of years?**
A: You can keep it up to a couple years.  Make sure it is tightly covered.

    Works as advertised
  

*by B***I on Reviewed in the United States on August 28, 2023*

I purchased and used Laticrete Hydro Barrier in 2018 for a tile bathtub surround.  I did my research first.  Watched all videos by the manufacturer and professionals on how to apply.  Bought the 6" membrane roll recommended for seams, corners, edges, etc.  It worked well.  The job took about three times as long as expected - I wasn't nearly as fast as the professional in the video - but I got it done.  AcrylPro tile mastic was the tile adhesive.  After 5 years, no leaks or shifting, tile adhered extremely tight (I removed and replaced one tile - no damages to the Hydro Barrier - and it was REALLY stuck).  So, professionals and DIYers ... do your own homework but this stuff is top on my list.

    Great Product if Applied Correctly
  

*by K***U on Reviewed in the United States on November 17, 2016*

First time using this product as I've used Hydro Ban and Redgard in the past.  Used this on shower walls and mortar bed pan in conjunction with Kerdi drain.  Dries much quicker than Hydro Ban and seems comparable in terms of finished application except that you need to use the fabric in the corners and around drain.  With elastomeric coatings you really need to let it dry completely before applying successive coats else you'll end up with built up layers that may be uncured in between and will end up blistering when you try to flood test the pan.  Best to wait at least 24-48 hours between coats depending on temperature and humidity.  Also you should let your mortar bed cure for at least 2 weeks.  Applying this over a mortar bed with too much moisture will also cause it to blister and peel.  However, if applied correctly, this product is excellent for waterproofing shower.

    Great Paintable Membrane
  

*by M***T on Reviewed in the United States on March 31, 2016*

This stuff is amazing. I use it along with the fabric. I built a shower pan using this instead of plastic. I put it under the mortar and above. Giving 5 coat and fabric tape on both. No problems. Also used it outside on an opening where a window was. Easy to work with. Shipping was easy and got here early BOTH times I ordered.
