Application of Liquid EPDM Rubber

Liquid Rubber® may be applied at any temperature that permits it being spread onto the surface. It will waterproof immediately upon application. The solvent will evaporate at a rate governed by temperature but will not be affected by relative humidity. Exposure to freezing temperatures before cure has taken place will not damage the film. The time necessary to reach cure should not be a concern as this process will occur automatically. Exposure to sunlight will accelerate the curing process. The final film properties of the cured membrane will be the same regardless of the time required to achieve cure.  EPDM Liquid Rubber® will provide long term protection even under extreme exposure conditions.  It is resistant to temps of 300 degrees F and minus 62 F.  Liquid rubber is water resistant even in an uncured state.  An unexpected rain shower shortly after application will not wash it off.  The slow cure and non-polar nature of EPDM Liquid Rubber® gives it outstanding surface wetting properties.  The product does not fill cracks and crevices but will produce an even film penetrating even the smallest surface irregularities.  When EPDM Liquid Rubber® is applied over porous surfaces such as poured concrete, pinholes will appear on the surface as the material slowly displaces the air in the pores.  This surface wetting feature enables the product to be applied in a SINGLE COAT and the still results in complete film integrity.  EPDM Liquid Rubber® can be applied to hot surfaces encountered during the summer.  The solvent in the system will flash off rapidly but the polymer will remain soft long enough to permit overlapping even after 1-2 hours.  The cure rate is still controlled even at temps up to 120 degrees.  The product can, therefore, be applied on the hottest day.  The controlled cure rate also results in a longer pot life, giving the applicator more than adequate length of time (4-6 hours depending on temperatures) to use the mixed quantity of material.  Adhesion will increase over time.  Polar surfaces such as metal, concrete and wood result in stronger adhesion than non-polar surfaces such as asphalts.  Most weathered surfaces including single ply and thermoplastic membranes will have enough of a surface profile to anchor the EPDM Liquid Rubber®

By itself, the EPDM Liquid Rubber® membrane will exhibit the characteristics of its EPDM chemistry i.e. U.V. ozone stability, excellent ponding water resistance and long-term retention of flexibility.  EPDM Liquid Rubber® applied over generally sound singly ply EPDM can extend its life another 20 years.  The useful life of metal roofs will also benefit greatly when EPDM Liquid Rubber® is applied. It is recommended that a corrosion inhibitive primer first be applied to areas where severe rusting has occurred.  EPDM Liquid Rubber® does not contain any corrosion inhibiting pigments but it is such an effective moisture barrier that it can be applied directly over light rust without a primer.  For more information contact at 866-311-3736 or visit their website at  They also have a blog filled with discussions from customers as well as valuable information on the product at

EPDM Roof Coatings are the best option for flat roof repair

EPDM is a black synthetic rubber single-ply roofing system that is typically mechanically fastened to the roof deck with screws and plates. They are sometimes covered with a layer of gravel or ballasted rock. Some of the problems with EPDM roof include moisture gain under the membrane itself, poor self-attachment at the seams and around pipes and other fixtures, UV radiation causing sealants to dry out and crumble, tenting, and punctures. EPDM (ethylene propylene diene monomer) is a synthetic rubber waterproofing commonly used on roofs.

Once thought to be incompatible with (electric field vector mapping system), due to too much black carbon interference, now has compatible grey and white versions! What does this mean? It means that if you want to use EPDM waterproofing under your green roof you can also have the peace of mind by having one of the most accurate leak detection systems installed as well! In many cases the leak detection system is cheaper than the waterproofing warranty as well.

 There are lots of types of roofs that a house can be designed with. The most usual type is the ridged roof, composed of a sheet made of different materials and laid on an inclined rafter. This is the most practical type of roof while it has sufficient slope to catch and release precipitation. These are common to most residential houses but are rare among skyscrapers and slab-ended buildings. However, there are buildings and houses that have flat roofing design. This type of roof has no proven benefits over the typical ridged type and is even vulnerable to collection of precipitation.

They only use this type of roof for architectural purposes. Because it is relatively flat, there is a small chance of water to freely slide through the slope and escape when there is ice formation blocking alongside eaves. Houses with flat roofs are prone to leaks during rain. This is a major problem unless immediately repaired. In cities like Shelton, there are roof repair companies that offer adequate roof repair methods that can be applied for various cases including leaks on a flat roof. However, roof repair method for flat roofs includes the following steps that can be done by the owner of the house without the help of a professional.

There are plenty of great things about EPDM commercial flat roofing that will protect you cash, especially in the long run. This kind of flat roof investment is flawless for individual buildings that have odd structures which typical roofing materials cannot fit well above. With EPDMs flexibility, it could fit on just about anything you deploy it on! This brings on in easier and cheaper installations, better waterproofing, along with a roof that lasts longer.

Repair costs are a huge issue with many businesses and might result in financial crises, but with EPDM Roof Coatings most repairs of punctures and tears are so cheap and easily done that you’ll hardly notice them. With very few repairs and maintenance jobs required for an in depth period after its installation, EPDM has demonstrated for being the single most inexpensive and protective roofing materials you should purchase.
