Ultimate Shower Protection

Your last line of defense in your shower is the waterproof membrane.  If water gets past your tile (which happens often) and past your waterproofing membrane, then it's going into your home.  Not good and causes a big problem.

That's why you always build up a waterproof membrane before tiling.  With Liquid Rubber Foundation Sealant, you can do this easily over a weekend.  Liquid Rubber allows you to waterproof those hard to do areas like curbs and niches that sheet membranes make really difficult.

It's as easy as painting, start your project today!

  1. Warranties are valid only for complete applications; partial repairs are not covered by this warranty. (Refer to application guideline)
  2. Failure to follow the procedures outlined in our application guidelines will negate this warranty.
  3. All recommended materials must be used in accordance with our guidelines, in the recommended quantities (coverage rates), and stored and applied in the required atmospheric conditions (e.g., temperatures, humidity, etc.). Refer to the product TDS sheets and application guidelines for details. 
  4. Register your warranty within 30 days of purchase by filling out the form on this page (You will need your order number and project details)
  5. If you have an issue or any questions, contact Liquid Rubber Technical Support within 30 days at 1-855-592-1049
  6. The warranty covers the replacement of Liquid Rubber materials needed to repair failed areas only and does not cover associated labor, tooling, or other costs.

You cannot transfer the warranty to another party.

The limited warranty only applies to the product and does not cover property damage, physical or economic loss.

Warranty is void if:
  • The coating is damaged due to natural forces, disasters, or acts of God (e.g., hurricanes, tornadoes, hail, lightning, earthquakes, insects, branches, or animals).
  • Directions in the guidelines, including adherence to conditional requirements (e.g., temperature, humidity, dew point, and coverage rates), are not followed.
  • Structural defects cause the coating to fail.
  • The coating is damaged as a result of exposure to harmful chemicals applied to the product or cured membrane.
  • Physical damage of any kind is caused to the membrane.
  • The product is altered in any way, unless explicitly instructed in writing by a Liquid Rubber Technical Specialist.

    You can apply over most acrylic/latex, polyurethane, alkyd paint, epoxy paints/coatings with the use of our Liquid Rubber Multi-Purpose Primer and using proper cleaning/preparation techniques. Keep in mind that when you apply over an existing coating or paint, if that coating/paint peels, our coating will peel with it as it is bonded to the existing coating/paint and not directly to the substrate.
