EPDM Liquid Roof

Designed for DIY use, we’ve made it quick and easy to seal all your leaks today.

1) Work out how much Liquid Roof you need
First off you need to get enough to cover your roof. 1 US gallon will cover 3.70 to 3.90 m2

2) Prepare your caravan or motor home roof surface
Once you’ve got enough Liquid Roof to keep you waterproof, it’s time to prepare the roof so it can adhere to your vehicle for years to come. As with many DIY projects, the key to a great finish is proper preparation in the first place.

The surface should be dry, clean and structurally sound
Use solvent to remove any oil or wax
Fasten any loose areas with an adhesive
Remove brittle caulk and loose portions of existing coatings with a scraper or wire brush
Wire brush rusty or pitted metal to remove any loose parts. Don’t worry, you can put Liquid Roof on well adhered rust
Remove any silicone
Remove asphalt based aliminium coatings with a wire brush
Repair torn rubber with adhesive butyl tape
How to repair gaps, holes or tears

Small gaps can be covered with butyl tape, then Liquid Roof can be applied directly on top.

Holes can be repaired with SpeedPatch, which can be cut to size on the roof. Sand this down to improve the adhesion of the Liquid Roof. For rough surfaces, use the UV Curing primer to prepare the surface before applying the SpeedPatch.

Small tears can be treated with butyl tape.

Temperature and cure conditions
The surface temperature must be between 12C and 26C. At these temperatures the rubber should be touch dry overnight and completely cured after about a week
Liquid Roof must be exposed to air
Liquid Roof is completely waterproof immediately after application and can withstand rain showers or pooling water before it has cured
3) Mix in the catalyst
This will begin the cure process, turning the liquid rubber into a seamless and flexible membrane that prevents any leaks.

Here’s where you’ll need your drill and a mixer. For US quarts and gallons a 9″ mixer is ideal. And for 5 US gallons, a 80mm mixer makes for a perfect fit.

Mix the rubber in the container for a round a minute, until the mixture is moving uniformally
Now angle the mixer and position toward the centre of the can, creating a vortex
Add the catalyst
Move the mixer up and down in a circular motion for 2-3 minutes until everything is completely mixed
4) Apply Liquid Roof
get out your brush, roller or squeegee (preferably all 3).

For flat surfaces, tip the material straight from the tin into a S like pattern onto the roof
Spread this evenly with the squeegee
Follow this up with the roller which will press air out of the cracks and result in an even film. Working time will be around 4 – 6 hours, depending on temperature. A single application is all that’s required
Apply by brush around flashings and edges, using long and smooth strokes
