  • Russell McKee | Retail First

    RTT Sealant has completed numerous waterproofing projects for Australia Fair Shopping Centre in Southport
    on the Gold Coast QLD, including sealing concrete cracks and expansion joints in the car parks as well as box
    gutters and ridge capping on the roof. I found the application team to be very accommodating and
    professional and their products have proved to be very effective and reliable.

  • Aaron Butteriss | Queensland Government

    Hi RTT Sealant, please pass on to your team that we are very pleased with the product. As you may
    remember the roof at Coorparoo Education Precinct was in need of replacement but due to the cost of
    removing and replacing the aged roof mounted air conditioning units it was not possible with the limited
    budget available. Your roof coating solution eliminated the need for removal. All roof leaks were fixed after the product was installed. The team that attended to carry out the work was a pleasure to deal with, always acting in a professional and safe manner.

  • Simon Gadd | Ozcare

    RTT Sealant completed major roof waterproofing and restoration projects at our facilities in Brisbane and Townsville. The projects were a complete success and not only does the roof look brand new with its bright white solar reflective finish, there are no more leaks into the buildings. Given the size and difficulty of the applications, the hard working RTT Sealant team was up to the task and did a great job. We look forward to working with them on future projects.

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

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.

Our Waterproof Sealant (Liquid Rubber) is chocolate brown when wet but cures black. It cannot be tinted.
