Brush-on Liquid Rubber Flat Roof

Benefits of Liquid Rubber Paint

Although liquid rubber paint has been around for some time, it is only recently that its application range and quality started to expand. It is especially useful for flat roofing uses. Keep reading to learn more about liquid rubber roof repair, its benefits, and how you should go about to apply liquid rubber coating.

Liquid rubber paint is one of the best waterproofing alternatives available today. These waterproofing qualities are due to a number of benefits.

UV Stable and Flexible

A coat of liquid rubber paint is incredibly flexible. It has an elongation capacity of up to 900%. This means that when the coat is exposed to the sun’s UV rays for a prolonged time, it won’t disintegrate or lose its structural integrity.

Because of its flexibility, it also moves with the substrate as it expands and shrinks. The substrate can be exposed to rapid temperature fluctuations from -40֩C to 160֩C and the coating will remain intact and keep protecting the surface.

Resistant to Chemicals

Liquid rubber paint is incredibly resistant to most abrasive chemicals, making it ideal for factory flat roofing. These chemicals include acids, alkalis, and solvents. It is also resistant to both liquids and gasses.


Since liquid rubber paint is waterproof and resistant to heat, acid rain, salt, and the sun’s UV rays, it is ideal for weatherproofing your roof. Applying a coat of liquid rubber paint to your flat roof will ensure that your roof is protected against the harsh elements for many years.

Versatile Adhesive

You can apply liquid rubber pant to almost any surface, including concrete, metal, rock, bitumen, EPDM, wood, Zinc and other metals, as well as PVC. It seals any substrate completely and protects it from corrosion, rust, moisture, and any other harmful substance.

Friendly to the Environment

Liquid rubber paint is water-based and completely VOC free. This means that it is not harmful to you, any animal that comes into contact with it, or the environment.


After application, the liquid rubber paint will form a non-permeable layer over the substrate that can withstand the accumulation of water. This layer is 100% waterproof and gas proof. It is also vapour tight, so you can rest assured that your structure is completely protected from damage.

How to Waterproof a Roof with Liquid Rubber

Liquid rubber paint can be easily applied to any surface, including metals, stone, concrete, PVC, wood, bitumen, or EPDM. You can also apply liquid rubber paint to foam. Application consists of three different quick and easy steps:

Step 1: Prepare Your Surface

One of the most common reasons for suboptimal performance of flat roof using liquid rubber coating is lacking preparation of the substrate. Before application, it is critical that you clear the surface from any chemicals, grease, dust, or particles. The surface also has to be completely clean and dry.

Step 2: Application

You should not apply liquid rubber in temperatures below 5֩ or if there is rain in the forecast for the next 24 hours. You can apply the liquid rubber paint with a roller, brush, trowel, or spray. The minimum thickness of the layer should be 2 mm. This thickness is built up with layering, and not gain through one thick coat.

Step 3: Film Curing

After application, the liquid rubber has to cure and bond to the substrate. This can take up to 72 hours and there should be no traffic or movement on the surface before then.

A rubber flat roof does not only look neat, but it offers the best in terms of protection, functionality, and effortless maintenance. Contact Roofers Dublin to discuss your liquid rubber flat roof needs.
