What is closed Combustion?

Liquid Rubber easily applies by brush, roller or spray and will retain its elasticity to expand and contract with your siding through the expansion and contraction of temperature variations.

It is a 100% acrylic formula that contains no solvents or VOCs, making it safe for application directly on surfaces where water based materials are normally not recommended such as damp wood foundations. It features an ultra-low VOC formula that meets the latest U.S. Green Building Council’s Leadership in Energy and Environmental Design (LEED) requirements for water based products, making it ideal to use on exterior surfaces of buildings seeking certification under LEED guidelines as well as those requiring a product with low odor and superior crack bridging capabilities such as manufactured homes or mobile homes.

Liquid Rubber is available in White and all 12 of our standard colors (for use on painted surfaces) or any custom color to match your project’s needs, allowing it to blend seamlessly into its surroundings while creating a waterproof barrier that protects the substrate from water damage.

Pros

  • Water based and solvent free.
  • Easy to apply with roller or brush, spray not recommended for large surfaces due to overspray/drift issues when using a garden pump sprayer.
  • Does not yellow over time like other products on the market that contain solvents such as Volatile Organic Compounds (VOC).
  • Retains elasticity to expand and contract with the siding.
  • Breathable surface that allows water vapor in or out of substrate keeping wall cavity dry, avoiding mold growth issues.
  • Low odor which is much more pleasant than other products on the market.

Cons

  • Cannot be applied to damp surfaces.
  • May lift paint on some surfaces if applied over existing paint (if not allowed to dry completely for up to 24 hours) or when applying on extremely cold days (<55 degrees F).

Recommended?

Yes, Liquid Rubber is the best liquid rubber sealant for all exterior surfaces. It’s water based so it can be applied directly to damp wood which makes it great for log homes or manufactured home exteriors.

It provides a breathable membrane that keeps moisture out while allowing vapor in keeping your wall cavity dry preventing mold growth issues often associated with excessive moisture in the cavity of your home.

Product Description

The Gorilla Rubber Waterproof Sealant is a rubberized waterproofing compound that works well for holes, cracks and crevices. It’s a great sealer to use in the bathroom where mold can be difficult to get rid of. When you have used it on small areas, allow at least 24 hours before using water again so that it can dry.

This rubberized waterproofing compound is clear and goes on easily with a brush or roller, making repairs to surfaces such as concrete sidewalks simple. It does take awhile for the sealant to dry so you should avoid any traffic through the area until it’s completely dried out. The 16 ounce size makes about eight gallons of material that you can use to cover up to 216 square feet.

The sealer is water-based, which makes it easy for cleanup with soap and warm water. It’s ideal if you are looking for a product that provides waterproofing without any oil or petroleum distillates in the ingredients list since these products often damage surfaces where they are applied.

Pros

  • A great sealant for small areas like holes, cracks and crevices
  • Waterproofing material is easy to clean up with soap and water
  • Product dries completely in 24 hours
  • Good product for spot repairs that won’t be walked through soon after application.

Cons

  • Product dries slowly so it’s better for spot, not large area repairs.
  • Applicator brush or roller is sold separately.
  • Takes awhile to apply and dry over 24 hours before traffic can be on the surface again (avoiding water).

Recommended?

Yes, this is a good sealant for those looking to waterproof their surfaces. It works well on small areas and dries completely in 24 hours so you can use your home as usual after that time frame has passed.

Benefits of using Liquid Rubber Waterproof Sealant

Liquid rubber waterproof sealant can be used to fill cracks, seams and joints in both horizontal and vertical surfaces. It is the perfect solution for all types of basements including cinder block walls as well as concrete driveways.

  • Liquid Rubber Waterproof Sealant has many other uses around your home or business such as filling gaps or holes under doors where they did not properly close and seal, at the bottom of patio doors where they meet the floor or around any type of door that isn’t weatherproofing your home.
  • Liquid Rubber Waterproof Sealant can also be used to waterproof concrete driveways, sidewalks and patios as well as repairing cracks in them without having to add a new layer.
  • Liquid Rubber Waterproof Sealant can be applied to brick, cinder block or stone walls to waterproof them.

Liquid Rubber Waterproof Sealant also allows you to paint over it without peeling or flaking.
  • Liquid Rubber Waterproof Sealant is also great for creating a moisture barrier on the inside of your home to help prevent mold and mildew growth as well as preventing damage due to humidity or condensation by sealing all areas where water can leak in including around windows, basement walls, doors and baseboards.

How to apply Liquid Rubber Waterproof Sealant?

There are three ways to apply liquid rubber, but the most common way is using a roller. This allows you to get an even coat and work it in deeper than with other tools. If your project calls for two coats of sealant then use the second coat after about six hours or when the first begins to dry out slightly. You can use a brush to get in the cracks and crevices. If you go this route, then it’s best if your surfaces are already textured because smooth ones will require sanding before applying the sealant.

Another way is by spraying it on with an aerosol can or pump sprayer which allows for more even distribution. A sprayer will be needed for any large projects, such as decks or roofs. The last method is with a paintbrush and that works best on smaller surfaces like windowsills and doors.

Tips for applying Liquid Rubber Waterproof Sealant

  • Shake the can well before you begin. This is especially important if it has been more than a few hours since your last use, or until the material becomes uniform in color again.
  • Make sure that your surface area is clean and dry before applying Liquid Rubber Waterproof Sealant to prevent contamination of its contents for optimal waterproofing.
  • Remove all objects from your work area, such as plants and other items that can be ruined by the Liquid Rubber Waterproof Sealant.
  • Liquid Rubber Waterproof Sealant is a do it yourself project perfect for sealing cracks and leaks in roofs, decks, basements and many types of masonry surfaces. Applying Liquid Rubber Waterproof Sealant is easy and requires only the following:
  • A clean surface free of dirt, debris or other contaminants. Make sure it’s dry before continuing to prevent mold growth with prolonged exposure.
