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
  • Safe for Fish and Plants
  • Do not apply later in the day if Dew is forecast

Makes trouble go Away

Recently put up a Quonset on a concrete pad. Added weather tape and silicon to bottom of base plates, GREAT. Rain came and flooded inside of building. Bad, uneven concrete work. Bought LIQUID RUBBER Waterproof Sealant, applied 3 coats and my troubles with water seeping into building went away. Can't say enough good things about Liquid Rubber and can't say enough bad things about the concrete company. They are lucky because I was going to have to go to court to force them to repair the problem. Now I can stop worrying about water problems. Liquid Rubber saved the day and the schedule. I highly recommend and will always have some on hand. Thank You Liquid Rubber.

Actually works

I have had basement leaks in my home since I moved in in 1978. The home is 96 years old and has a concrete basement that leaks in many, many locations, mostly where the floor and wall meet but I have had leaks higher up on the wall also. We put the mesh tape along the wall/floor joint and in any places that have leaked further up. There is only one leak we didn't fix because I have to move a big shelf. I am smiling so big this morning because after days of rain, I have NO leaks except for the one that wasn't fixed yet. I was sceptical that this would work because everything was previously painted with Drylock and it only made a minimal difference. I put towels down, as always, just in case and am happy to say the towels weren't needed. Thank you Liquid Rubber! I am a very satisfied customer.
