Things to Remember When Applying Liquid EPDM

1)      Catalyst must be added prior to use.  Scrape sides of container with a rubber spatula to ensure catalyst distribution.

2)      Xylene or Mineral Spirits Solvents may be added to adjust viscosity or for clean-up.

3)      Easiest way to spread the rubber on a flat surface is to broadcast material with a rubber squeegee then roll using a short nap roller.  Product is self leveling.  A flat spatula can be used for small areas.

4)      Product has a long pot life after catalyst has been added; 4-6 hrs. depending on temperature.

5)      Only temperature affects the rate of cure.  Relative humidity has no influence. 

6)      Product is hydrophobic (sheds water) so substrate to be coated must be dry initially.  The uncured rubber can get wet or even have ponding water, with only a cosmetic effect after application, and will still cure.

7)      The rubber will penetrate into porous substrates such as wood and poured concrete.  A primer/sealer should precede application of rubber.

8)      The chemical reaction of the catalyzed rubber can be arrested by freezing the material.  This can keep material usable for weeks or months.  To use again simply allow it to reach room temperature and apply.

The Commercial and Industrial Use of EPDM Coatings

Here’s a look at the commercial and industrial use of EPDM coatings. The waterproofing and weather resistance of the material has made it popular for many uses. There are other advantages as well.

For Vehicles

The coating is most commonly used to help protect the metal roofs of RVs and tractor trailers, often as an after-market product. A few RV suppliers offer the coating as an add-on to extend the life of the roof leaks or to reduce maintenance.

Many components of vehicles are made of the synthetic rubber. The liquid coating is sometimes used to protect pumps, valves and other engine items from heat, friction, water or weather.


Flat roofs are the ideal choice for the coating. Contractors can offer the coating to their roofing customers as an alternative to other less waterproof materials with shorter life spans.

EPDM can be used directly on any material other than silicone or asphalt. It can be used on concrete floors to reduce noise on stucco as weatherproofing and on chimneys for example. It can also be used to cover wood and siding. A special coating is usually recommended for slanted and vertical surfaces.

One of the advantages for roofs is that it allows for rainwater harvesting. The coating does not pollute the rainwater. So, the water can be used for cleaning, gardening and other purposes.


One commercial and industrial use of EPDM coatings is in the area of refrigeration. Manufacturers of walk-in refrigerators, refrigerated trailers and similar items use the coating for improved insulation. It has good resistance against heat, which is one reason that it has become popular for roofing.


Pond manufacturers typically use the coating because of the water-resistance. Pond liners are typically composed of the material. The non-polluting feature is one reason it makes a good choice for this application.

Pools and Decks

A commercial and industrial use of EPDM coatings is in the area of pool and deck installation. The coating creates a non-slippery but soft surface that enhances the safety of wet walkways and decking. The coating also helps to protect the decking material from the water to increase the lifespan of the wood.

General Construction

The coating is a good choice for many construction purposes because it is compatible with so many different materials. Existing concrete, wood or brick can be coated with the liquid rubber to extend the life of the underlying material. That’s one reason there is no single commercial and industrial use of EPDM coatings. There are many.

Application of liquid rubber coatings

Application of Liquid Rubber Coatings Starts with Preparing the Surface

The application of liquid rubber coatings is easiest when the surface is flat, clean and smooth. As is the case with all painting jobs, the most time-consuming part could be cleaning and repairing the surface.

How to clean the surface depends on the material. For metal roofs, sweeping and/or washing may be all that is necessary. You should make sure there is no debris on the surface, because any debris will show through the coating.

Concrete floors should be as smooth as possible. If cracks or holes are present in any material, fill them with a non-silicone based caulking. The rubber would fill the hole, but a dent would still be visible. Depending on the depth of the hole, this could cause a variety of problems in the future.

For some older roofing materials, it is a good idea to reinforce the surface with butyl tape and polyester fabric. For example, if there are gaps, tears or other defects, you would want to correct those problems. Although the coating does not adhere to all materials, it does adhere to fabric.

Rubber Liquid

Depending on the surface to be covered, a catalyst coating may be needed. For example, the application of liquid rubber coatings to existing asphalt-based roofs requires a pre-coating with an elastomeric catalyst. Follow the manufacturer’s directions concerning what type of pre-coating to use.

Generally speaking, latex house paint is not an acceptable solution.

You will need a squeegee, a roller and a paint brush to apply the coating, once the surface has been prepared. The thickness usually recommended for the coating is 20-mil. It may be necessary to do a spreading rate calculation to get an idea of how that thickness can be achieved. A good estimate for a flat smooth surface is 40 feet per gallon. The application of liquid rubber coatings to uneven surfaces will require more.

The product needs to be spread as evenly as possible. You want to avoid making it thicker in some spots and thinner in other areas. The squeegee is used initially to spread the material. It is recommended to follow the use of the squeegee with a roller to promote more even distribution and get rid of any air bubbles that may be trapped within the liquid.

The first 2 gallons usually take one or two hours to apply. If you have already determined how many gallons you need, this should give you an idea of how long the application of liquid rubber coatings will take. You should be able to get the job done in a day.

Information about Liquid Roof and Its Benefits

Here you can learn a bit about liquid roof and its benefits for new and existing construction. Let’s start with the basics.

What Is It?

Liquid roof is a liquefied version of a synthetic rubber typically referred to as EPDM. The letters EPDM stand for ethylene, propylene, diene monomer and M class respectfully.


Before the liquefied version came on to the market, rolls of the rubber were used for waterproofing roofs. The liquids are easier to apply. They fill up cracks and crevices. They can go where the sheets could not go.

Why Choose the Liquids?

Ease of application is one reason. The foil is more difficult to apply correctly. You could easily end up with bumps, overlaps and uneven spots that contribute to water pooling. Water can seep under the rubber sheets and cause the roofs to leak. So, while the rolls were the best choice for waterproofing at one time, there are better choices today.

The liquids have more uses. They can be used on RV roofs and other vehicles. They can be applied to a wide range of roofing materials including metal, fiberglass and wood. Through the use of an undercoating, the liquids can be applied to built-up and asphalt-based coatings. Other reasons to choose the liquids are listed in some detail below.

Liquid Roof and Its Benefits for New Construction

For new building construction, applying the liquids increases the lifespan of caulks and sealants used to waterproof around flashing, vents, HVAC units and other protrusion points. If the new roofs are made of steel or aluminum, the liquids prevent rust and effectively extend the life of the roofing material.

If you choose white, which is the base color typically provided; the coating reduces heat within the building and also helps to protect the surrounding environment from excessive heat. Black and dark colored roofing materials are partially to blame for the high temperatures seen in southern cities during the summertime. By reducing heat within the building, the coating helps reduce air conditioning costs.

Liquid Roof and Its Benefits for Existing Construction

When applied over the entire area, the coating provides the same benefits for existing roofs as it does for new ones. It can also help to reduce noise from rain falling on metal roofs.

For roof leaks and general waterproofing, the roof coatings are the least expensive and most effective choice. So, there you have the facts about liquid roof and its benefits. It’s a money-saving environmentally friendly alternative.
