Why Use Liquid Roof?

EPDM Liquid Roof is no ordinary caravan/motorhome sealant. It’s premium quality chemical design make it a cut above. Unlike the normal acrylic elastomeric coatings, which are vulnerable to fail in sudden showers or freezing temperatures, Liquid Roof is the liquid form of the highly durable EPDM rubber.

That means Liquid Roof has the same advanced weatherproofing benefits that made EPDM sheets a worldwide feature in the roofing industry. Highly flexible, incredibly durable and UV and extreme temperature resistant. EPDM is backed up by decades of trusted roof waterproofing by thousands of professionals. Using Liquid Roof you still get all the benefits of EPDM but in an easy to apply liquid form. This means that next time your roof is drumming with heavy rain, you can sit back and relax, knowing Liquid Roof has completely sealed any leaks.

Not just for caravan/motorhome roof repair. A premium chemical make up makes Liquid Roof a versatile sealant, ready to stop leaks in numerous surfaces, including: caravan and motorhome roofs, large RV vehicles, mobile homes, house boats, narrowboats and much more.

NOTE: If you are sealing your roof at temperatures below 12 Degrees C, you might want to look at our Moisture Cure range.

What Customers Say

“We recently installed Liquid Roof on the roof of our houseboat. Liquid Roof was installed over unpainted plywood, fibreglass, painted wood and aluminium. It bonded very well to everything! Installation was relatively easy and the final result looks great! We are extremely pleased and have been recommending it to everyone on our dock! Thanks.” – D Skipper

Kit includes:
1 x Gallon (US) Liquid Roof, 1 x 2″ brush, 1 x mixing stick, 1 x roll of 6″ x 10ft reinforcement fabric
One gallon will cover 3.9sqm
Colour: White
Get the surface clean and dry. Mix in the catalyst. If you want a clean edge you can use masking tape on the edges and remove as soon as the coating starts to become tacky. Pour onto the roof and apply with brush, roller or squeegee. If you’re using fabric for extra reinforcement or small repairs, embed the fabric into the moisture cure over the affected areas. You can also use a Speedpatch to repair holes before coating.
Drying Times:
The surface area must be 12c or above. At these temperatures the coating should skin over in a few hours and be touch dry over night then completely cured after a week. It is completely waterproof immediately after application but if rained on the raindrops may leave small indentations.

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 aluminium 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

“Our roof was in such bad shape before we realised it, that we ended up with a completely soaked through bed. After researching different products, we decided to use Liquid Roof. The instructions were simple enough and it only took about 2 hours to apply the liquid roof. The next day, it rained and the roof got put to the test. We checked inside and there was no moisture at all. The water beaded up on the roof. What a relief. So far we are extremely happy with the results.”
