Owatrol varnish is the perfect solution to stop your corten steel products rusting any more than you'd like them to!
Owatrol varnish penetrates through the rusted metal to the sound metal below, isolating it and protecting it from further rusting.
It is available in 2 size cans, 0.5 litres & 5 litres. 1 litre will cover approx 18sqm.
We recommend using Owatrol on all corten steel products as the benefits speak for themselves - no more bleeding out colour, no flaking, and a perfectly desired rust.
PLEASE NOTE THAT UNFORTUNATELY WE CAN'T SELL THIS PRODUCT ON IT'S OWN AS THE COURIER COSTS ARE TOO EXPENSIVE FOR US TO COVER. WE DO APOLOGISE FOR THIS!
