The true Liquid EPDM rubber available in the market is Liquid Roof. The advantages that this liquid rubber coating offers are countless. It is waterproof, has high compatibility with almost all types of surfaces, very flexible and elastic and can withstand a large temperature range from -62 degrees F to 300 degrees F without cracking.
There are some tips which must be kept in mind before applying liquid rubber on your roof. Be aware that it is a 3 to 6 hrs process, excluding the surface preparation time. Once the liquid EPDM Rubber is applied, it takes around 16 to 20 hours to dry up. Therefore proper management of time is necessary. Careful planning regarding weather conditions should be done as well, i.e. one should plan to work on days when the rain is not expected because although Liquid Roof will immediately waterproof, even when wet, avoid heavy rain until it is completely dry to the touch which means 16 - 20 hours after application. To be on the safe side, one can say that a full cure will be achieved in 4 - 10 days after application, in consistent 70 deg. F.
The extensive and useful spray and application characteristics of liquid roof make it very unique and different from the other coatings. Surface preparation before application of liquid roof is a compulsory step because this is done to ensure that there are no holes, gaps, seams, and tears on the roof and if there, they should be repaired before application. Any potential weak areas should be reinforced and asphalts or silicone type of caulking on the roof / surface should be removed as well. The roof should then be thoroughly dried.
Properly catalyzing the liquid rubber with a pre-measured catalyst according to instructions is very important. Always try to apply a single coat of the product for best results Liquid rubber penetrates through small surfaces and pores despite the fact that it has high consistency. Use a squeegee or a roller for flat surfaces. Spread with a squeegee and then level it with a short nap roller. The liquid roof can easily be applied to areas which are small and difficult to access e.g. chimneys, roof flashings, pipes, fish ponds etc with a paint brush. Application of a 20 mil layer of the liquid roof is recommended for efficient results.
