Choosing the right product for your application requires some knowledge of the strengths and weaknesses of each type of product available on the market today.

Liquid roof coatings are aftermarket products designed to extend life, seal leaks, provide a heat reflective or aesthetic function over existing roof surfaces. There are many products on the market ranging from asphalt based products, rubber solution (Hypalon, Neoprene, Silicone), water based Acrylic and other emulsions, and chemically curing systems such as Urethanes and now Liquid Roof®. 

The most widely used liquid coatings by the RV industry are Acrylic elastomeric products. The weakness of these products, however, comes from the fact that they are water-based emulsions, which makes them vulnerable to sudden showers or freezing temperatures soon after application. They have inherently poor resistance to standing / ponding water. Another drawback for the Acrylic products is that they do not work over single ply EPDM membranes. 

Liquid Roof® is a true EPDM rubber and therefore could be described as a liquid version of the single ply EPDM membrane that has established an outstanding performance record for over 30 years. The EPDM chemistry has two unique features not possessed by any other rubber: It is unaffected by ultra-violet and ozone, and can tolerate continuous exposure at temperatures over 300° F. This feature is what gives EPDM rubbers the best aging properties (retain flexibility longer) of all the elastomers.

Liquid Roof® and our Commercial/Industrial product EPDM Liquid Rubber® are the only true liquid EPDM products, we know of, on the market worldwide today. 

Liquid Roof® provides more benefits to the RV industry than any other liquid coating on the market.

RV manufacturers have been using white single ply EPDM rubber for many years. These units are now experiencing chalking and occasional damage. Liquid Roof® is the best and most cost effective product on the market for solving these problems. 

Given all of the available information, Liquid Roof® is the best product for your RV roofing needs. 

Any damaged areas may require Butyl Tape and Poly Fabric in addition to Liquid Roof® to make repairs.  Both of these items can be purchased through us.
