  • Reduces cracking in top coatings by up to 95%.
  • Encapsulates asbestos and lead in existing deck.
  • Use indoors and out. Non-Toxic. Cleans up with water..

Waterproof Membrane / Universal Coatings Primer


Specified to bond epoxies, decorative concretes, etc., to any surface

The complete waterproofing, crack isolation, and substrate reinforcing system for use with all decorative coatings.

What does the PerfectMembrane® do?

  1. Overlay adhesion primer: Bonds decorative coatings to concrete, wood, tile or existing coatings, without grinding.
  2. Waterproofing membrane: Converts any surface into a waterproof deck. Ideal for roofs, balconies, bathrooms, etc.
  3. Crack isolation membrane: Reduce transfer of substrate movement that cause cracks in your top coatings up to 90%
  4. Reinforces weak substrates and weak or severely cracked surfaces. Perfect for going over existing coating systems.

PerfectMembrane® combines perfectly with your decorative coatings.
The only underlay system specified for the overlay industry.

Inexpensively and properly prepare and waterproof all deck surfaces for your decorative coatings.

Unlike rubber or epoxies, PerfectMembrane® moves and bends so that the substrate and top coatings act as one. Never needs to be replaced. (see comparison chart)

Materials calculations:

PerfectMembrane® is made on site from our PerfectPrimer and Polytex fabric.

To order Our PerfectPrimer Membrane system: Figure out how many sq. ft. of membrane you need. Then order the amount of PerfectPrimer® and Polytex Fabric® that you need accordingly:

Coverages to make the membrane system:

  1. PerfectPrimer: 40 sq. ft per gallon.
  2. Polytex fabric: Choose your roll size.

For example, if your project requires 400 sq. ft of membrane, you will need: Ten gallons of primer (40 sf per gallon x 10= 400 sf.) Plus a minimum 400 sq. ft. roll of fabric.

Or Simply choose one of our membrane packages.


PerfectMembrane application process overview

Spray, brush, or roll (use 3/8” roller) to apply a foundation coat of Primer onto an area a little wider than the fabric and approximately 3′-4′ long. Apply fabric into this wet area. Working from the center out to the edges, use hands, brush or roller to smooth it out, forcing the base coat to come up through the material. Leave no wrinkles or air pockets. Apply a second coat on top of the fabric, and roll flat until no white fabric is visible.

PerfectMembrane®, The only way to waterproof and prepare decks for coatings and overlay systems.
