Waterproof & Heat-Protect Your Roof in a Weekend.

For the best waterproofing results, apply Liquid Rubber to a clean, dry roof. Remove loose or peeling coatings, silicone, rust scale, and other contaminants first. This ensures maximum adhesion and long term leak protection for your roof.

Usually, no. In most projects you only need to seal the problem areas: rusty patches, seams and joints, around skylights and vents, laps, screws and penetrations, and any spots where water can pond. Targeting these areas stops leaks while saving time and materials. In rare cases, such as when large sections are rusted or existing coatings are failing everywhere, a full roof application can be helpful. Make sure the substrate is still structurally sound because severely rusted or weakened roofs may require repair or replacement. Where the metal is sound, a full coat helps encapsulate the rust and can extend the roof’s lifespan.

Application is simple. Use 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 suitable cleaner handy for spills and tool cleanup.

Apply two coats of Liquid Rubber waterproof sealant. If your surface requires it, start with one or two coats of the appropriate primer (etch primer for bare metal; sealer for painted or porous surfaces). For heat reduction, finish with two coats of our thermal coating.

Both will seal seams and stop leaks. Choose based on the repair. Geo Textile suits most projects and uses a simple three step method: first a layer of liquid rubber, then the textile, then another layer of liquid rubber on top. This rubber textile rubber method is versatile and cost effective. Seam Tape is ideal for bigger holes and gaps. It has a sticky backing, so you peel the liner and press it directly onto a clean, dry surface without laying liquid rubber first. It saves time and effort but usually costs more. In short, Geo Textile is universal but needs a little more work, while Seam Tape is faster and easier at a higher price.

No. The thermal coating is optional. It adds strong UV protection and reflects heat, which helps the roof stay cooler and can extend its life. If you want waterproofing only, untick the Thermal Coating and the primer or sealer in the calculator.

Choose any colour you like. For performance, brighter colours work best. White gives the strongest UV reflection and heat protection. Dark colours reflect less UV and will run warmer.

Allow each coat of Liquid Rubber waterproof sealant to cure for 24 to 48 hours. Primer coats typically dry in 2 to 4 hours. For the thermal coating, wait 24 hours between coats for best performance.

Yes. It is suitable for common Australian roof types including corrugated iron or Colorbond, Trimdek or Spandek, Klip Lok or Snaplock, concrete, fibreglass, PVC, EPDM rubber, and TPO. Follow surface prep guidance for the best results.

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.

We ship 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.

Yes, it is safe. If you're collecting rainwater for drinking purposes, disconnect the downpipes for the first downpour to allow the system to wash thoroughly before reconnecting. Alternatively, once the thermal coating has fully cured, you can power wash the surface and then reconnect the downpipes. Liquid Rubber DIY products are safe for rainwater collection and will not compromise water quality after the recommended washing process is complete.
