Hi Ron, the perfect product for that type of application is the Aqua Proof Primer. The Lanco Aqua Proof Primer is a liquid membrane and styrene butadiene latex that provides an easy alternative for many waterproofing applications as a base membrane. Due to the chemical composition of the Aqua Proof, it works very well as a bonding agent between coats.

Tried this to fill in low spots on a TPO roof. Comments section said it could be used for that. Did not adhere properly and curled after it dried. Very brittle and cracks. Followed all instructions to the letter. It leveled well but is not durable.

Great for leveling
This is a cement based leveling compound. It's strange to read complains about powder not being pre mixed and cracks after application. Do you people know what cement is??? It can not be pre mixed and cracks are expected. Educate yourself prior to complaining. It's not a water proof membrane. It's a leveling compound . Apply water proof membraine on the top and problem solved. Great product !!. Highly recommend for it's indending use -leveling. Very easy and does a great job.
