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 Multi-Purpose Primer or a 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
  • Safe for Fish and Plants
  • Do not apply later in the day if Dew is forecast

Roof repair

Following directions, application was easily completed, several coatings applied.
Want to know, what the shelf life is for opened container...treat the same as paint, cover opening with thin plastic, then secure lid tightly?
Any other suggestions
Don't expect to use 'til summer of 2021.
Would appreciate your reply...thank you.

Hello, The shelf life for an opened container is 1 year when stored properly as you mentioned, treat the same as paint, cover opening with thin plastic, then secure the lid tightly. Store between 10-30C and do not allow it to freeze.

This product is vey user-friendly. It is the exact thickness to not come off your brush unintentionally. The brown color is a beautiful wood color. The shiny sheen was an unexpected real bonus, in regards to overall appearance. The product is extremely durable. After 24 hours you can hard-scrape it with a thumbnail without damage. It can be hard-scrubbed with a stiff brush to remove contaminants without damage. It is also very flexible, to allow for expansion and contraction due to ambient temps.

Good Stuff!!

Very happy with the consistency of the product and the way it covered the surface. Both coats dried well. Very satisfied
