Great Pack

The kit has everything you need to do the job but had to buy a bit more of the mesh. Have done up to the reflective paint stage but should get that done over Xmas. Thank you for a great product.

Step 1: Clean the Caravan Roof

Thoroughly wash your caravan roof using a pressure washer to remove dirt, debris, and any old sealant. For best results, scrub flaky or loose areas with a wire brush to ensure the ideal surface for waterproofing.

Step 2: Seal Seams, Cracks & Joints

Pre-cut geo-textile for seams, joins, downpipes, and holes. Apply using the Rubber-Geo-Rubber method: a layer of liquid rubber, the geo-textile, then a final layer of rubber sealant for full encapsulation.

Step 3: Apply the Waterproofing Coating

Paint on two full coats of Liquid Rubber waterproofing using a roller or brush. For extra protection in high-stress areas, add a third coat. Allow each layer to dry for 4–12 hours before recoating.

Step 4: Prime the Roof

Use our Sealer/Primer for painted or aluminium roofs, or Etch Primer for bare metal surfaces. This step ensures maximum adhesion and long-term waterproofing. 💡 Tip: Use the Kit Builder to select your roof type and get the right primer.

Step 5: Apply the First Thermal Coat

Wait about 2 hours for the primer to dry completely, then apply a generous layer of Liquid Rubber Thermal Coating for optimal coverage.

Step 6: Second Thermal Coat for Full Coverage

After 6–12 hours of drying, apply a second coat of thermal coating for full coverage and insulation. For high-exposure or sun-baked areas, a third coat is recommended. Use a roller or brush for even results.

Step 7: Enjoy Your Waterproofed Roof

Congratulations! Your caravan roof is now sealed with Liquid Rubber, giving you a seamless, waterproof, and insulated barrier. Protected from leaks, heat, and harsh weather for years to come.

Can I apply Liquid Rubber waterproof sealant over existing caravan roof coatings or sealants?

For the best waterproofing results, apply Liquid Rubber to a clean and dry caravan roof. Remove old roof coatings, silicone, or loose materials before starting. This ensures maximum adhesion and long-term leak protection for your caravan.

What tools and equipment do I need to waterproof my caravan roof?

Applying Liquid Rubber DIY waterproofing is simple. You only need a paintbrush or roller (included in our kits). Basic safety gear such as gloves is recommended, and keep a cleaning agent handy for spills or cleaning your tools.

How many coats of Liquid Rubber or primer should I apply for caravan roof waterproofing?

To ensure your caravan roof stays fully waterproof, apply 2-3 coats of Liquid Rubber sealant directly to the clean and dry surface. Then apply one coat of primer over the rubber and the remaining roof area, followed by 3 coats of thermal coating over the waterproofed area and 2 coats over the remaining roof area for the best UV protection and heat reflection. The product amounts in our kit builder are calculated to be sufficient for up to 3 coats.

What is the recommended curing time for each coating?

Allow the waterproof sealant to cure for 4-12 hours between coats and be fully cured within 72 hours for a strong, weatherproof bond. The primer cures in 2-4 hours before the thermal coating can be applied. For the thermal coating, wait 6-12 hours between coats. When in doubt, 1 coat a day keeps problems away.

Is Liquid Rubber safe and effective for all types of caravan roofs?

Yes, Liquid Rubber is designed for use on all common caravan roof types found in Australia, including metal, aluminium, fibreglass, vinyl, PVC, EPDM rubber, and TPO. Our formula provides safe, reliable waterproofing and long-lasting results for every roof.

Can I apply Liquid Rubber waterproofing in different weather conditions?

For best results, apply Liquid Rubber when the weather is dry and mild. Avoid application if rain, dew, or strong wind is expected within 24 hours. This helps your new caravan roof coating cure properly and prevents moisture from interfering with adhesion.

How long does shipping take for Liquid Rubber DIY kits in Australia?

We offer fast shipping Australia-wide. Orders typically arrive within 3 to 8 business days. Local pickup is also available at 1 Conway Court, Nerang, Gold Coast, QLD 4211.

What colour is the Waterproof Sealant?

The Waterproof Sealant appears brown when wet but turns black when fully cured. If you want a coloured finish, we recommend applying a primer on top of the cured sealant, followed by a top coat in your chosen colour. This approach ensures both waterproofing protection and creates enhanced UV resistance and provides longevity.

When is the best time to apply?

Apply in dry, mild weather. Avoid application if rain, dew, or strong winds are expected within 24 hours. This helps the coating cure properly and prevents moisture from affecting adhesion.

DOCUMENTATION & MAINTENANCE

Caravan Roof Maintenance Tips for Thermal Coating

Keep your Caravan Roof protected and maximise the lifespan of your Liquid Rubber DIY Thermal Coating with these essential maintenance tips.

Inspect your caravan roof regularly:
Check your Caravan Roof every few months for any signs of damage, wear, or peeling coating. Early detection helps prevent leaks and prolongs waterproofing.

Reapply Liquid Rubber DIY Thermal Coating when needed:
For the best long-term performance, add a fresh layer of Thermal Coating every few years. This keeps your caravan roof fully protected against heat and weather.

Clean gently with pH-neutral detergent:
Wash your caravan roof with a mild, pH-neutral soap and a soft broom or sponge. This removes dirt and debris without damaging the protective coating or reducing its heat-reflective properties.
