One of our customers installs liquid rubber - check out their top tips

We’ve had a rough couple of months in the UK with strong winds & torrential rainfall but dare we say it the storms of 2020 have passed (hopefully) and Spring looks to be on the way. Bad weather can cause water ingress; any water coming into your home or a building is bad news. It can cause immediate damage as well as leading to further and more expensive problems down the line.

One of our customers recently installed our band new liquid rubber waterproofing on their roof as a preventative measure to avoid any future leaks. To ensure a high performance result preparation and the right techniques are vital when working with our liquid rubber coating. We caught up with Chris after he’d installed to form a quick & easy installation guide sharing tips & tricks he learnt along the way.

3 simple steps to installing liquid rubber:

Step 1 – Calculation

After discussing with one of our advisors Chris was given the correct quantities for his roofing. As a rule of thumb on roofing felt liquid rubber covers up to 1m2 per 1.5kg. Check out full coverage rates below:

Concrete - approx 1.8 kg / m²
Sheet metal - approx 1 kg / m²
Joins - 0.3 kg / linear meter

Step 2 – Preparation

As with the majority of coatings surface preparation is key to achieving a high quality finish. The surface you’re planning on coating with liquid rubber should be completely dry and free of any dust or dirt. Simply use a wire brush to remove any debris creating a nice, clean surface.

In Chris’ case there was no need for any repairs of gaps or tears however if your roof does have tiny holes or perforations bigger than 4mm our geotextile tape can be easily used to reinforce these before coating then with liquid rubber.

Step 3 – Installation

A benefit to our liquid rubber coating is the fact it requires no primer & is an easy one coat application. Chris chose to apply the coating used a standard roller; on a large or flat area simply pour a small amount of the liquid rubber and distribute evenly with the roller. The product can also be applied with a sprayer.

One of the key features Chris highlighted when we spoke with him was just how workable the product was and how far it went.

*Top tip – around flashings or chimneys use a brush applying long strokes for a neat finish.


The curing time is generally anywhere between 12 hours with higher temperatures increasing the curing rate. Liquid Rubber requires exposure to air to cure with the product reaching its full waterproofing properties within 48 hours.

*Top tip – Always apply the product to a completely dry surface
