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