Frequently bought together


One coat of Watco's roof paint seals and weatherproofs most surfaces and provides a tough, slip resistant finish. The colours can be used to indicate clearly where access is permitted on the roof. The thick, flexible formulation also makes an ideal emergency repair since it can be applied in the wet and is immediately water repellent. 

Great for walkways, flat roofs, effective weatherproofing for flat or pitched roofs and plastic or metal gutters. Not suitable for roofs with a lot of foot traffic, for this use Watco Liquid Roof Membrane Anti Slip.

Surface preparation

Remove loose material and dirt. Apply a suitable fungicide solution to surfaces contaminated with moss or algae etc. Emergency repairs may be carried out in the wet but we recommend that the surface is as dry as possible if undertaking long term repairs or complete refurbishment.


If appearance is critical we recommend the application of a small trial area first.

Apply at temperatures above 5°C. Stir well before use. One coat generously applied by brush or medium pile roller is generally sufficient.
