How to Waterproof Roofs and Gutters

Roofs and gutters take a beating from the Australian elements. Heavy rain, high UV exposure, and constant temperature changes wear down your materials over time. Cracks, leaks, and loose joints will lead to serious water ingress if you ignore them.

You need products that provide professional performance and are simple to use on site. Our liquid waterproof coatings and hybrid sealants deliver an instant barrier. You can even apply some of these products on wet surfaces. They remain fully elastic once cured to handle natural building movement.

These products bond easily to concrete, cement plaster, bituminous membranes, metal sheets, timber boards, and plastics. They are cold-applied systems. This means you don’t need to heat or mix anything before you start working.

Our waterproofing solutions include Soudagum Hydro  for a quick temporary fix that can be applied while wet & our Roof & Gutter Silicone for massive durability and UV resistance. Together, they give you a system to seal and protect exposed surfaces.

FAQs

Can I apply roof sealant while it is raining?

Yes, you can use specific products like Soudagum Hydro for emergency repairs during a downpour. It displaces the water to create an instant seal.

How long does roof and gutter silicone take to dry?

Most neutral cure silicones like Roof & Gutter will form a skin within 10 to 15 minutes. Full curing takes about 24 hours depending on the temperature and humidity. Do not expose the fresh silicone to heavy water pressure until it is completely cured.

Do I need a primer for Soudagum Hydro?

No. You can apply this coating directly onto most common roofing materials without a primer. It bonds strongly to zinc, steel, concrete, and timber right out of the bucket.
