Flexible Heavy-Duty Coating

  • ENVIRONMENTALLY FRIENDLY - Liquid Rubber Color Waterproof Sealant is water based, containing no Solvents or VOC's. This means it's safe to use indoors and outdoors with no special breathing apparatus like solvenated products need. You're safe, your children are safe and your pets are safe. We believe you should have a choice in purchasing high quality products that are safe for you and the environment
  • USED FOR: Flat Roofs, Metal Roofs, Sloped Roofs, Planter Boxes, Foundations, Sheds, Basements, Metal, Wood, Concrete and more...
  • See DIY APPLICATIONS for more specific info
  • EASY TO APPLY - Basically just like painting except you use heavy coats to build up your waterproof membrane. Open the container and start using. You can close the container and use later if you have left over material. No pot life or working time like 2 component products. Apply by Brush, Roller or Good Quality Paint Sprayer
  • HIGHLY FLEXIBLE - UV Stable - Final membrane has over 1000% Elongation and the Sun will not degrade the product.
  • FOR A BULLETPROOF SYSTEM - Bridge joints, seams, vents, gaps, protrusions…. With LIQUID RUBBER SEAM TAPE or LIQUID RUBBER GEO-TEXTILE where possible movement may occur.




  • Flat/Ponding Surface

    Apply a minimum final thickness of 1 gallon per 15 sq ft (1.4 sq/m). It should require around 4-5 heavy coats to achieve a 60-80 mil  (1.5-2.0mm) (DFT) membrane.

  • Vertical Surfaces

    Apply a minimum final thickness of 1 gallon per 25 sq ft (2.3 sq/m). It should require around 2-3 heavy coats to achieve a 30 mil  (0.76mm) (DFT) membrane.




  • Avoid hot, direct, intense sun when applying.  Mornings and Evenings are best if it's blistering hot
  • Product stays soft, flexible and may have some tackiness, not meant as a constant walking surface
  • Apply next heavy coat when it's dry to touch (typically 6-8 hours), make sure there is no uncured material underneath.  Tacky is ok
  • Generally you can apply 1-2 coats per day
  • Apply all material until you use up the required amount
  • Do not combine Black products with Colored products, use one or the other
  • For larger areas, pour out and spread around with a broom, roller or squeegee
  • If corrosion/rust is present, use a water-based rust primer.
  • Use EPDM/TPO Primer for EPDM/TPO substrates.  Use Multi-Purpose Primer for PVC and Concrete Surfaces
  • Apply above 10C/50F
  • Curing time depends on temperature, humidity and airflow
  • Apply next coat(s) as soon as possible not allowing extended time between if possible
  • Do not apply later in the day if Dew is forecast

Brant Pearson

Have a small A-Frame cabin with a metal roof. Has anyone ever used it in this application?

Hey Mr. Pearson,
That product has been used on many metal roofs with great success. You can download our Metal Roof Guideline from our website for full application instructions.

Robert Wade
Works as it should

This is great for my flat roof on my camper. Just 2 coats totally sealed the roof and with sever rains last week, no leaks were found. Easily went on with a roller. Just what I needed. Complete satisfaction.

Omar McDermott

I love this product. At first it was hard to judge coverage. But the more I use it the better I understood how to apply it. It doesn't seem to work for me with rollers. I haven't tried using a spray gun yet though. What sprayer do you recommend?

Hello Mr McDermott, Because the product is so thick it requires a heavy duty airless paint sprayer such as a Titan 440 or a Graco GH 733/833 or equivalent model. If needed the product can be thinned with up to 5 % distilled water by volume.
