Liquid Roof-features and Applications

EPDM liquid rubber or liquid roof has a successful long history and superior repute in hoses, molded products, roof leaks repair, tires and roofing membranes. No doubt it is a product which is worth to use for roofing problems. It has many distinguishing features, characteristics and applications which makes it prominent among other roof coatings. This article is specially written with the aim of providing a complete insight to this remarkable product. Its composition, properties both physical and chemical along with its applications will be discussed in detail.

Liquid roof is a true EPDM rubber in liquid form. Therefore it possesses all the characteristics and features that are typical of EPDM coatings. Chemically Liquid Roof is a liquid elastometric copolymer rubber, based on a low molecular weight terpolymer of Ethylene and Propylene with a pendant group of Dicyclopentadiene. The cure mechanism of liquid epdm is determined by temperature and varies from active to inactive. Faster cures and slow cures over extended periods of time result in identical physical properties. Broad day-night temperature swings in spring and fall will not compromise the final physical properties of the Liquid Rubber Membrane.

The physical properties of liquid roof are countless. They combine all the benefits of EPDM rubber roofing with the flexibility of using a liquid. Liquid roof coatings are better than many the sheet form coatings commonly used in the roofing industry. It is highly waterproof and therefore is highly resistant to water penetration. It is highly elastic and has the capability of tolerating a very high temperature range i.e. from 300 degrees F to minus 62 degrees F. It is also very strongly resistant to many chemicals; acids, alkalis and polar solvents. It is also ozone and UV stable. Also it is highly reflective which gives it an upper hand over many other non reflective roof coatings because when applied over the roofs it delivers a cooling effect, decreasing cooling costs to a great extent. It is a very durable product and if properly applied, it can greatly increase the life of existing roof materials (particularly roof coatings) and reduce the amount of torn-off roofing waste going into landfills. Its weaknesses include oils, fats and waxes will swell the polymer.

Liquid rubber when applied over a cracked surface not only fills cracks and crevices but will produce an even film penetrating even the smallest cracks and irregularities. The slow curing and non-polar nature of EPDM Liquid Rubber give it outstanding surface wetting properties. This surface wetting feature enables the product to be applied in a single coat over non porous surfaces and still result in complete film integrity.

Liquid roof is highly adhesive in nature and its adhesion increases over time. Polar surfaces such as metal, concrete and wood result in stronger adhesion than non-polar surfaces such as asphalts and single ply EPDM sheet. It is compatible with a large number of surfaces like metal, rubber, fiberglass, concrete, fabric and foam. Liquid roof can be applied with a paint brush, roller or squeegee. It is a one coat application product that results in saving both time and money. It is available in colors like white, black and custom colors. Custom colors are available for orders over 100 gallons.

There are tremendous applications and uses of liquid roof. It is an ideal coating for various forms of roof repair like RV roof repair, metal roof repair, and many more. Liquid roof sticks to the entire types of facades- canvas, plywood, suds, cement, mass rubber, customized roofing, additional roof coverings, strengthen, timber, top tiles, genuine tiles and solids. It is also employed for coating the roofs of newly constructed buildings. It can also be used over decks, pool liners, underground room waterproofing, and channels. Liquid epdm rubber also provides protection to the concrete surfaces of fountains and fish ponds against both the fresh and salt water. Its nontoxic nature and safety for the fishes makes it best for waterproofing pond liners.

Liquid roof, no doubt, is among the best roof coatings available in the market.
