Step-by-step DIY guide to waterproof, seal, and restore your caravan roof using Liquid Rubber DIY.

Waterproof Your Caravan Roof in 6 Simple DIY Steps
Finish with a thermal barrier that keeps your caravan cooler and protected all year round.

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
Apply Liquid Rubber to all seams, joints, and cracks on your caravan roof. For added strength, embed the included Geo-Textile fabric while the sealant is still wet. This creates a flexible, long-lasting seal.

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 calculator below 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.

Caravan Roof Waterproofing Comparison: Liquid Rubber DIY vs. Traditional Roof Sealants
Compare Liquid Rubber DIY with conventional
caravan roof coatings and sealants.
Discover the best way to stop leaks, protect your investment, and enjoy lasting results without expensive
professional installation.
Feature | Traditional Roof Sealants & Paints | Liquid Rubber DIY Waterproofing Kit |
---|---|---|
Caravan Roof Waterproofing Performance | Often leaves small gaps or cracks that let water in, which can lead to leaks and damage over time. | Forms a continuous, watertight layer across your entire caravan roof. Effectively stops leaks and keeps water out year after year. |
Flexibility and Durability in All Conditions | Most coatings become stiff and start to crack when the weather gets too hot or cold. | Liquid Rubber stays flexible and moves with your caravan roof. It won’t crack or peel, even during extreme heat or cold in Australia. |
DIY Application and Ease of Use | Many products are tricky to use and often require hiring a professional or special equipment. | Anyone can apply Liquid Rubber using a brush, roller, or sprayer. No special skills or tools are needed—just follow the simple instructions. |
UV Protection and Weather Resistance | Tends to break down in the sun or after heavy rain, so you have to recoat more often. | Built for Australian conditions, Liquid Rubber stands up to harsh sunlight, rain, and wind. Your roof stays protected and looks great longer. |
Eco-Friendly and Cost Effective | Contains harsh chemicals, has a strong smell, and usually needs to be replaced more often which adds to the cost. | Water-based and non-toxic, Liquid Rubber is safe for your family and the environment. It also saves you money by lasting much longer than traditional coatings. |
Adhesion, Versatility and Low Maintenance | Doesn’t always stick well to different surfaces, so repairs are common and maintenance can be a hassle. | Sticks securely to all common caravan roof materials including aluminium, metal, and fibreglass. Needs very little maintenance after application. |

Frequently Asked Questions About Caravan Roof Waterproofing
Find answers to the most common questions about DIY caravan roof waterproofing, Liquid Rubber application, shipping, and best practices for long-lasting caravan roof protection in Australia.
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.
Applying Liquid Rubber DIY waterproofing is simple. You only need a paintbrush, roller (included in our kits), or a spray machine for larger roofs. Basic safety gear such as gloves is recommended, and keep a cleaning agent handy for spills or cleaning your tools.
To ensure your caravan roof stays fully waterproof and insulated, apply two coats of Liquid Rubber sealant. If your roof type requires it, start with one or two coats of primer. Finish with two coats of our thermal coating for the best weather protection and energy savings.
Allow each coat of Liquid Rubber waterproof sealant to cure for 24 to 48 hours for a strong, weatherproof bond. Primer coats typically dry in two to four hours. For the thermal coating, wait 24 hours between each coat for optimal insulation and protection.
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.
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.
