TRUSTED BY INDUSTRY LEADERS:

Step 1: Clean and Prepare the Surface

Wash or water-blast the entire container to remove dirt, debris, and any loose or peeling paint.
Use a leaf blower to remove excess water and ensure the surface is completely dry before application.

Step 2: Reinforce Seams, Joins, and Holes

Pre-cut Geo-Textile to fit over all seams, joins, and holes.
Apply a first coat of Liquid Rubber Waterproof Sealant with a brush to these areas.
While the sealant is still wet, embed the Geo-Textile into the sealant, making sure to smooth out air bubbles and wrinkles.
Once positioned, spray Rapid Cure Spray to set the product and speed up drying.

Step 3: Apply Waterproof Sealant to Entire Surface

Once the reinforced areas have dried, apply a first coat of Waterproof Sealant across the entire shipping container using a brush, roller, or spray machine.
If rain is expected, spray Rapid Cure Spray after application to set the product quickly.

Step 4: Apply Sealer/Primer

Once fully cured, wash the surface again to remove any dirt or dust.
If the container 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 to protect against UV exposure and improve heat reflection.
Apply 3 coats over 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 Shipping Container?

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 my Shipping Container waterproofing?

To ensure your Shipping Container 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.

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 Shipping Container Maintenance Tips for Thermal Coating

Keep your Shipping Container protected and maximise the lifespan of your Liquid Rubber thermal coating with these essential maintenance tips.

Inspect your Shipping Container regularly:
Check your Shipping Container every year for any signs of damage, wear, or peeling coating. Early detection helps prevent leaks and prolongs waterproofing.

Reapply Liquid Rubber thermal coating:
For the best long-term performance, add a fresh layer of thermal coating every few years. This keeps your Shipping Container fully protected against heat and weather.

Clean gently with pH-neutral detergent:
Wash your Shipping Container 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.
