The ultimate Liquid Rubber DIY system combines our waterproofing sealant as a base coat and our acrylic top coat applied over that. This is the ideal way to restore and protect any industrial or commercial roofing system.

Our high performance coatings offer durability, waterproofing and UV resistance so you can cool your building, reduce energy costs and improve your bottom line. Our specialised formula will extend the life expectancy of your roof and protect your building against future problems.

“Waterproofing represents around 1% of the total building costs. Water leaks and the subsequent damage account for around 80% of all building defects.”

Liquid Rubber DIY is also the perfect solution for all commercial roof repairs and corrosion protection. Being of the highest quality and yet totally affordable, Liquid Rubber DIY offers protection from the harsh environmental elements. The application is quick and easy so there is no need to stop trading to fix your roof or waste multiple weekends on ineffective silicone repairs. In fact, a complete roof restoration using Liquid Rubber DIY products can cost less than half of a traditional roof replacement!

For ALL your waterproofing and sealing needs!

Roofs aren’t the only things Liquid Rubber DIY waterproofing sealant can fix. It can be applied to gutters, foundations, planter boxes, wet areas, retaining walls, water features, ponds and decks. You can even waterproof a cardboard box with it! It is non-toxic and certified potable, so it’s completely safe for use in drinking water tanks and other water containment systems.

Liquid Rubber DIY should also be paired with our Thermal Top Coat to create the ultimate dual layer, UV resistant and heat reflective barrier to further reduce the heat inside any structure. This cooling effect will increase the energy efficiency of any structure using air conditioning. Absolutely essential in the Australian summer Liquid Rubber DIY and Thermal Top Coat here.

We only offer the best quality products direct from the manufacturer at the lowest price. Now you can do it yourself and save! But if you do need some help completing a project, please contact us and our professional, all Australian team can assist you or refer you to one of our qualified applicators in your area!

Contract Us

Liquid Rubber products have been around for over 100 years. We only provide the highest quality Australian Made products and have tested and successfully proven these products on our own projects since 2008.

We produce our own products and they are all 100% Australian-made and owned.


When properly applied, our products will last for a minimum of 10 -15 years. We give a 10 Year warranty when we apply the products for our customers.

Our Waterproof Sealant is applied at 1.5L/m². So our 15L pail will cover 10 m² and the 4L pail will cover just over 2.5m²

Our Thermal Coat is applied at 0.6/m² The 15L pail will cover 25m² and the 4L covers 6.5m²

We suggest you get some extra as it’s always best to have a bit more.

It does depend on the thickness it is applied and the weather conditions. But generally the Waterproof Sealant needs 24 – 48hrs per 1mm of coating. Tanks should be left empty for at least 7 days before refilling.

The Thermal Coating again needs half the time to cure, but don’t use it in tanks as it’s not designed to be underwater. 

The Thermal Coating is fully cured after 2-3 days.

Right here with our online store is the easiest option, we offer 1 day processing. But if you want to collect it today please give us a call at 1300 2 LRDIY and arrange a pickup time. 

The Liquid Rubber DIY – Waterproof Sealant is chocolate brown when wet but cures black. It cannot be tinted.

The Thermal Coating is white but can be tinted to any colour. So you can apply the Thermal Coating ontop of the Waterproof Sealant if you want a different color.
