Durability of Liquid Roof Coatings

--> -->

Liquid Roof is a liquid elastometric copolymer rubber coating that has excellent elongation, tensile strength, UV resistance and durability. Cures to a hard white or light gray rubber heat reflecting coating!
The material factors that influence durability are complex and related to the chemical composition of the liquid constituents, the thickness of the system as well as the type and density of the reinforcement. Central to the long-term success of liquid-applied waterproofing systems is preparation of the substrate and achieving the required membrane thickness.
Typically, manufacturers only guarantee their products when applied by approved and trained installers. This is not surprising as standards of application by squeegee, roller, brush or spray are very demanding; layers are measured to tenths of a millimetre and avoidance of air holes is essential. The weather conditions in which the liquid is laid are critical as are the times between application of coats.

Other key durability issues include:

* Ensuring the substrate construction and condition is free from material which may impair the bond, create thin spots or penetrations in the coating.
* Provision for moisture removal of damp substrates.
* Ensuring there are no point loads on the roof.
* Specifying a system suited to the expected traffic load.
* Appropriate detailing at edges, verges, upstands, outlets, movement joints and day joints.


Liquid-applied coating that forms the waterproofing layer of an inverted roof should not require replacement during the life of the building, provided it is fully protected from ultra-violet radiation and extreme temperature variations by a loading layer above it.

By increasing the longevity of roof materials by using cool coatings, organizations can avoid a substantial amount of roofing waste. There are an estimated 11 million tons of asphalt roofing waste going into landfills every year. Using liquid roof coatings can greatly increase the life of existing roof materials (particularly roof coatings) and reduce the amount of torn-off roofing waste going into landfills. The roofing waste that remains can be recycled into road mixes using existing processes already operating.

Liquid Roof is a liquid elastometric rubber coating that has excellent elongation, tensile strength, UV resistance and durability. Liquid roof is a true EPDM rubber and is available in liquid form only. In fact it is the liquid version of single ply EPDM membrane, one can say, Liquid EPDM. It can be employed for both repairing and replacing the EPDM or sheet rubber roof. Its features such as waterproofing and easy application over all roofing materials, UV and ozone resistance, elasticity and long term flexibility, capability to withstand large temperature range i.e. from -62 degrees F to 300 degrees F without cracking or deteriorating, make it very different from other roof coatings. It is also a one-coat application product, ultimately saving both time and money.

Liquid Roof and liquid rubber are super-strong and waterproof, and is able to survive tremendous temperatures of warmth and chilly. The liquid form makes it possible to apply EPDM rubber to many materials regardless of their shape. It cures by chemical reaction at ambient (ordinary) temperatures to form a flexible rubber membrane. A pre-measured catalyst is added to the rubber compound before application. 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.

Technical Data and Physical Properties of Liquid Rubber

When we talk about the nature of EPDM Liquid Rubber the slow curing and non polar nature of the EPDM Liquid Rubber give it a tremendous and outstanding surface wetting properties. EPDM Liquid Rubber can’t only be used to fill cracks crevices but will produce an even film penetrating even the smallest cracks and irregularities. 

A sound example of this said sentence can be that when EPDM Liquid Rubber is applied over the 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 over non porous surfaces and still result in complete film integrity.

Here are some technical properties of EPDM Liquid Rubber:

EpdmCoatings improved its liquid roof product quality to satisfy customers’ demands

When the time comes for first full maintenance, liquid roof coatings can be easily refurbished usually by the application of an additional coat. Through development and improvement of the systems through the years, Liquid Roof Coatings have been designed to withstand the toughest climatic conditions and are compatible with the majority of roof and balcony substrates.

EPDM Coatings has improved its product quality to meet customer’s demands and give long time roof life expectancy. With traditional resurfacing materials, such as felt, it can be difficult to achieve a 100 per cent waterproof surface especially in areas where detailing is difficult. Protrusions such as pipes and surface-mounted roof lights cannot be easily detailed by these materials alone. By contrast, liquid roof and liquid rubber coatings can be applied anywhere where one can reach - providing total, fully adhered and seamless protection. A long-term solution to the problem of water ingress, liquid coatings are highly durable and long lasting, offering up to 25 years’ protection.

Liquid Roof coatings are the Elastomeric chemical compounds that can be applied to surfaces in liquid form and which quickly ‘cure’ or dry to form a solid waterproof membrane. Bitumen was the first form of liquid coatings and has been used for the purpose for thousands of years. In the last two decades, huge advances have been made in liquid coatings technology and there are now many other generic types of liquid systems available. Most of these compounds can be installed cold and are typically applied by brush, spray or roller.

Liquid EPDM Rubber vs. Neoprene Rubber for waterproofing concrete pipe and vessels

EPDM rubber was not available in liquid form until relatively recently so Liquid Neoprene rubber became the material of choice for protecting concrete against both fresh and salt water. The Liquid Neoprene products are simple solvent solutions or water based emulsions and therefore have low solids content and relatively low molecular weights. These limitations made multiple coat applications necessary and required top coating with other polymers to prevent ultra violet degradation.

The development of Liquid EPDM Rubber resulted in a high solids, two components chemically reactive product capable of polymerizing at ambient temperatures( 55 F ( 13 C) and higher). This product can be applied at a 30 mil dry film (.76 mm) in a single application because of the high solids content. Its chemical cure feature then results in a high molecular weight film with protective and performance properties exceeding those of liquid applied Neoprene films.

EPDM Liquid Rubber can withstand boiling water or live steam and is inherently UV and ozone stable. The product is safer to use because of its higher flash point and the two component packaging permits extended storage at higher temperatures than liquid Neoprene. The non polar characteristic of the EPDM also gives it advantages over Neoprene in saltwater environments as well as better resistance to cathodic disbondment.

EPDM rubber has poor resistance to oils, fats, waxes and aliphatic solvents but possesses very good resistance to ketone solvents, alcohols, polar compounds, Salts, most acids up to 50 % concentration, alkalies and water.
