Answer

HI Bxbathroomremodel, the Lanco Aqua-Proof is a liquid membrane and is made of a styrene /butadiene latex that provides an easy alternative for many waterproofing applications as a base membrane. Unfortunately, for that type application, the existing tile should first be removed to achieve the best performance of the Aqua-Proof.

How long should we wait to test if it sealed a leak? 24 hours?

At least 24 hours. This is thick stuff.

Does this meet ASTM D41 standards?

Asked by Pete August 8, 2020

Answers

I am confused by one of the answers to your question. One of the questions above ask if you can use this primer for the LIBERTY SBS Self Adhering Cap Sheet and the answer was yes, but the manual says to use a "Asphalt Primer (ASTM D41 type)... is the base foundation on your roof deck to promote good adhesion when applying the LIBERTYTM Cap Sheet." So long story, can we use this primer with the Liberty SBS Self-Adhering Roofing System One (1) Ply Installation????

can I use it in my shower before the tile ???

Hi checha, yes the Lanco Aqua-Proof is a liquid membrane of styrene /butadiene latex that provides an easy alternative for many waterproofing applications as a base membrane.This monolithic membrane provides excellent performance when used as a base coat over horizontal or vertical surfaces and performs extremely well during continuous water immersion. The Lanco Aqua-Proof is perfectly designed to be used as a protection under tiles in wet areas such as bathrooms, food processing areas and balconies.

Can this be applied to painted drywall then tiled over?

Answer

Hello Southernsunflower, the Aqua-Proof is a liquid membrane made of a styrene/butadiene latex, which provides an easy alternative for many waterproofing applications as a base membrane. It can be used as a secondary protection under tiles in wet areas such as bathrooms, food processing areas, balconies and similar situations. It can also be used under render or plaster as a water barrier or vapor barrier.

I have tried three other products over the years in an effort to stop leakage in my waterfall and none could do the job. Finally I found this product and based on reviews gave it a try. Used two coats and after a full month can report "no leaks, no drips and no errors". Fantastic product.
