Step 1: Clean and Prepare the Surface

Wash or water-blast the entire houseboat roof or deck surface to remove dirt, debris, and old coatings.
Use a leaf blower to remove excess water and ensure the surface is completely dry before applying any product.

Step 2: Reinforce Seams, Joins, and Holes

Pre-cut Geo-Textile to fit over seams, joins, any holes, skylight etc.
Apply Liquid Rubber Waterproof Sealant with a brush over these areas before embedding the pre-cut Geo-Textile into the wet sealant.
Smooth out the textile to remove any air bubbles or wrinkles.
Once set, instantly spray Rapid Cure Spray to secure the area and speed up the drying process.

Step 3: Seal Screws, Rust, and Railings

Screws do not require Geo-Textile—simply apply a small amount of Waterproof Sealant over them with a gloved finger.
Spray Rapid Cure Spray over the treated screws to instantly set the sealant.
Apply Waterproof Sealant to surface rust, pipes, and railing bases for extra protection. Allow it to cure before proceeding.

Step 4: Apply Sealer/Primer

Once fully cured, clean the surface again to remove any dirt, salt, or natural debris that may have settled.
If the surface was previously painted, apply Sealer before adding the final coating. If working with raw metal, apply Etch Primer to ensure proper adhesion.

Step 5: Apply the Protective Thermal Coating

Once dry, apply Thermal Coating for additional UV protection and heat reflection.
Apply 3 coats over the Waterproof Sealant or 2 coats minimum over primed metal surfaces.

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

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

What tools and equipment do I need to waterproof my house boat 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 house boat roof waterproofing?

To ensure your house boat 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 house boat roofs?

Yes, Liquid Rubber is designed for use on all common house boat 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 house boat 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.

DOCUMENTATION & MAINTENANCE

House Boat Roof Maintenance Tips for Thermal Coating

Keep your House Boat roof protected and maximise the lifespan of your Liquid Rubber thermal coating with these essential maintenance tips.

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

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

Clean gently with pH-neutral detergent:
Wash your House Boat 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.
