 Metal Roof

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

Once you have applied one coat of Liquid Rubber and let that cure for at least 24-48 hours you can apply Premathane Top Coat letting dry in between coats.

Can be applied on its own in two coats or with Liquid Rubber to build a durable waterproof membrane.

Make sure that the application layers are thin but good coverage.

Ensure that the surface is clean prior to application. (Please refer to Technical Data Sheet for more detailed instructions).

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 / Premathane Top Coat 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, buzz-on system etc.
