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.

Buildings

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.

Refrigeration

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.

Ponds

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.

Liquid roof and its benefits

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.

Technical Aspects of EPDM

Elastomeric coatings are roofing applied in a viscous state. It has elastic properties, and can stretch in the summer time heat and then return to their original shape without damage.

Elastomeric coatings usually contain polymeric materials, such as acrylic, and a white pigment, such as titanium dioxide, to make them opaque and reflective. An elastomeric coating is applied thicker than paint. An elastomeric coating can be used on virtually any substrate including asphalt built-up roofing, concrete roofing, metal roofing, modified bitumen roofing, polyurethane foam roofing and single ply roofing.

Since EPDM Liquid Rubber Coatings cures by chemical reaction, a single heavy application will be preferable to multiple thin coats. A second coat will bond to a previous film but that bond will not be as strong as the internal bond within each layer. If a second coat is applied before the first has thoroughly cured, some wrinkling may result as the first coat absorbs solvent and swells. This will, however, recover as the solvent evaporates. It is generally recommended that only a single coat be applied over non-porous surfaces, the thickness of which can be varied as desired. Thicker films will take longer to cure through. Asphalt coatings and asphalt built-up roofs are considered unstable substrates and therefore, not recommended for coating directly with Liquid Rubber EPDM. EPDM COATINGS do carry a specific elastomeric which with a two coat application gives you a 10 year warranty.

Liquid Rubber is designed to re coat structurally sound existing roof and protective materials. They are also best for RV Roof Repair. They should not be used in place of roofing membranes”.

The following are recommended substrates to coat:

  • Metal – Coated or Galvanized Steel
    • Weathered Aluminum
    • Weathered Copper
  • EPDM Rubber membrane
  • Concrete (except foot traffic surfaces)
  • Urethane Foam
  • Primed Wood
  • Fiberglass
  • PVC Sheet and Pipe
  • Acrylic Sheet
  • Sponge Rubber insulation

Do Not use Liquid Roof or Liquid Rubber on the following substrates:

  • Built up asphalt roofs
  • Asphalt shingles
  • Modified asphalt roll roofing
  • Stainless steel
  • Glass
  • Silicone caulk
  • Foot traffic surfaces
  • Hypalon Membrane

Liquid Rubber For Ponds and Plywood Application

Liquid Rubber Fix pond leaks. Waterproofing Fish Pond, Leaks Repair, pond liner, Fountains, & Reflecting Pools with Liquid EPDM Rubber Concrete which has not been modified with special additives must be protected by impervious coatings when used for containing water. Unprotected concrete will absorb water which can then leach out soluble constituents and cause spalling when frozen. The combination of outdoor exposure plus water immersion creates a demanding environment for a coating. It must have high resistance to water penetration, be flexible enough to withstand extremes in temperature, and not be affected by ultra violet radiation from the sun. Liquid EPDM rubber coatings possess all this characteristics and are also non toxic to fish.

Preparation. Drain water and clean surface dirt while concrete is still wet. High pressure water spray and/or scouring surface with a wire brush may be necessary in fish ponds. If algae are present treat with an algaecide or 25% solution of bleach, let stand for one hour and rise well. Allow one week (rain free) for concrete to dry out.

If you are using this in Koi tanks in immersion conditions, make sure you have 2 coats of Liquid EPDM and that you have a full cure. To do so, let cure in air (without water) for about 1 week in 70 deg F or more ). Soak and rinse out the tank several times with water before making this ready for the Koi. The soaking and rinsing is to ensure you get out any residue solvents after the curing process. You will of course need to prepare the water for the Koy in whatever normal way you prepare Koi tanks/ponds.

Roof Repair, Roof Maintenance, Roof Leaks

Whether your pond is concrete, plastic or rubber lined. EPDM Liquid Rubber can fix your leaks troubles. Plastic pond liners have a tendency to crack or to tear. There are products such at tapes and caulks that will eventually wear. EPDM Liquid Rubber, on the will not. For concrete ponds the easiest solution for leaks are to cover them with a rubber liner but they are tricky to install. Liquid Rubber Coatings provides an easy one-time solution to your pond leak regardless of if they are made of rubber, concrete or plastic. And yes, it is safe for fish!

 

Liquid Rubber for Coating Plywood:
Liquid Rubber Coatings has been used directly over plywood to make a finished roof in situations where expediency and minimal cost were the primary considerations. Although this procedure results in a weaker roof structure, water-tightness can be achieved if the application is performed carefully. The joint between sheets should be positioned directly over a roof truss and securely fastened to prevent warping. Next, to seal the pores, coat plywood with an oil based primer. Allow an overnight cure. Seal the joint by bridging it with a 6″ wide polyester fabric strip. Apply a light coat of EPDM rubber over the joint, lay fabric into wet rubber and smooth out wrinkles. Complete job by applying a liberal coat of Liquid Rubber over entire roof surface, being especially careful to completely cover the fabric over the joint without skips or pinholes. Using an oil base primer on the wood considerably improves the appearance of a one-coat application of Liquid Rubber.

Liquid Rubber is excellent for Wood Surfaces Repair Product; Liquid Rubber can be applied to wood. We recommend first applying a primer coat using an oil base primer and then the Liquid Rubber after the primer has dried. Liquid Rubber can be colored using “universal” colorants available at any paint store. You can add up to one cup per gallon of paint thinner for easier handling when going over wood. Liquid Rubber is slippery when there is only a fine mist of water on its surface. Silicone and oil-based materials are considered unstable and should be avoided.
