What can Liquid Rubber be applied to?
Liquid Rubber can be applied to virtually anything that is not oil based including concrete, wood, brick, masonary, most metals (iron, steel, galvanised steel, aluminium), butynol, shingles, tiles, difficult roof materials including EPDM, TPO, most PVC, SBS, APP, BURs, propylene, polystyrene, fiberglass and OSB. If you are unsure, please contact us to discuss your requirments.
Can you guarantee that Liquid Rubber works?
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.
Where are you products made?
We produce our own products. All our products are 100% Australian-made and owned.
How long does the product last?
When properly applied, the products will last for a minimum of 10 - 15 Years. We give a 10 Year warranty when we apply the products for our customers.
How much product do I need?
Our Waterproof Sealant is applied at 1.5L/m². So our 15L pail will cover 10m² 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 buy extra as it’s always best to have a bit more.
How long does the product cure?
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 Protective Top Coat again needs half the time to cure. (Do not use it in tanks as it’s not designed to be underwater).
The Protective Top Coat is fully cured after 2-3 days.
What color is your Liquid Rubber and can it be tinted?
Our Waterproof Sealant (Liquid Rubber) is chocolate brown when wet but cures black. It cannot be tinted.
The Protective Top Coat is white but can be tinted to any colour. So you can apply the Top Coat ontop of the Waterproof Sealant if you want a different color.
