Was my first time using it seamed to work well. I used for a rust protection on a box gutter. Would like to see how it last during Perth's hot summer.

Clip-Lock Roof


Hi Paul,

I cannot thank you enough for not only the great product but the advice you gave us about the sagging Clip Lock roof. As soon as I got up on the roof after our call it was like someone took the blind fold off me. For years I have been chasing holes but now I could see that everywhere I had sagging Clip Lock is where all the bad leaks are. We just had the tail end of a cyclone with half a year's worth of rain dropped in two days here in Perth and I am happy to report 100% no leaks.

Thank you once again,

D. & J. Byrne.

House Boats


Thank you for your advice and the bandage which we have put to use. We have found Liquid Rubber to be a very easy product to use on our paddle boat roof and upper deck. We are now looking forward to rain so that we can test your product and put the bucket chandeliers away!

How to apply

1. Clean the surface as well as possible.

2. If required, apply bandage with Liquid Rubber to all joints and junctions, cracks, screw holes.

3. Apply a thin coat of Liquid Rubber with either a brush or a roller.
Think of it as normal painting; nice and even application. DO NOT APPLY TOO THICK LAYERS!

4.Let cure in between layers for about 24-48 hours, depending on temperature and relative humidity.

5. Apply second coat of Liquid Rubber and let cure 5-7 days.

NOTE: Ponds and water tanks at least 3 coats of Liquid Rubber required. Let cure for at least 2-3 weeks before filling with water.
Please refer to our more detailed Application Guide prior to starting your project.

NOTE: If you are after other than a black finish, you can do one layer of Liquid Rubber and then 2 layers of Thermo Top Coat.
Thermo Top Coat is white in color or can alternatively be tinted to any color to your liking. Thermo Top Coat is specifically designed to work with Liquid Rubber and is much more flexible than normal paint.

Shelf life

Once opened Liquid Rubber keeps for about 6 months. Just make sure you seal the lid properly!
Store in a cool dry place over 5°C – DO NOT ALLOW THE PRODUCT TO FREEZE


Liquid Rubber membrane is NOT an ideal surface on itself if you wanted to place tables or chairs etc. on top of it. In fact this might in time dent the membrane and compromise the waterproofing aspect.

On decks and balconies you can top of Liquid Rubber with tiles, synthetic turf (Arma-Blue protection sheet to be applied in between), decking, pebble-mix etc.
