Wessex System 200 solvented epoxy: Surface preparation

Preparation of surfaces

It is essential that the correct surface preparation is carried out before the first application of this solvented epoxy system.

Epoxy Coated Wood

The substrate must be well sanded with 80 to 120-grit paper in order to achieve a good bond. Brush away sanding dust before coating.

Metals

All previous surface pre-treatments should be removed, taking the surface back to bare metal by abrading or grit blasting; the substrate should also be degreased. The use of an adhesion promoter is advised on non-ferrous metal substrates and specific information on a suitable preparation is available on request.

Concrete

Remove all loose concrete and any contamination by wire brushing and acid etch with a dilute hydrochloric acid solution. Subsequently wash with fresh water and thoroughly dry the surface.

Wood

The timber surface must be clean and dry and it is recommended that the wood is well sanded with 120-grit paper. Ensure that sanding dust is cleaned away and, if necessary, degrease oily wood with a solvent.

GRP

The surface should be mechanically abraded and thoroughly degreased. Wipe off all dust.
