Cromapol is a one component, UV stable, solvent based multi-purpose roof coating membrane.
Cromapol is manufactured with fibre reinforcement pre-dispersed in the can, for ease of application.
Cromapol is used for Waterproof Protection of:
Flat and Pitched Roofs
Whilst minimal preparations are required, the surface must be sound and free of loose or friable materials.
To obtain the best result remove all surface debris and surface water using a stiff broom.
Repairs to cracks, holes etc, must be carried out prior to coating.
Fungus, mould and lichens must be removed, additional protection against fungal spores can be achieved by applying Moss and Algae Cleaner.
Oil or grease must be removed prior to application.
Any existing coating must be inspected and adhesion tests carried out.
Apply by brush. In extreme cases, a second coat may be applied 2-3 days after initial application.
Cromapol is easily applied using a brush or roller.
Treat all details first, in areas where excessive movement may occur additional reinforcement can be incorporated into the coating.
Cromapol can be applied in one coat, but experience has shown that a two coat application ensures a greater uniformity of coating thickness.
Cromapol requires no primer on most surfaces but where air borne pollution is heavy a coat of Bitumen Primer may be necessary. It is therefore good practice to carry out adhesion tests prior to application of the coating.
Cromapol will tolerate damp surfaces although with any application for best results apply to a dry surface if possible.
Approx 1 - 2kg per m² on average.
