Wessex System 310: Surface Preparation

Steel

Degrease the surface (use WEST SYSTEM 850 Solvent, acetone, methyl ethyl ketone or isopropanol) before removing all previous surface pre-treatments.

Take the surface back to bare metal using 80-grit paper and degrease again after abrading.

Apply the epoxy adhesive soon after the steel surface has been abraded and degreased – ideally within two hours – to minimise oxidation of the metal.

Aluminium

A similar procedure can be adopted as for steel. But to maximise the bond strength of the adhesive to aluminium, an etching compound may be applied after degreasing.

To minimise the oxidation of the aluminium, it is important to apply the adhesive within fifteen minutes of completing the surface preparation.

Wood

All previous coatings must be removed, and surfaces should be dry, free of contamination and abraded with 100-grit paper.

Note: if the adhesive is to be applied to an oily wood such as teak, degrease the surface of the timber with one of the solvents recommended for steel. To ensure that the surface does not become greasy again, apply the adhesive to the wooden substrate soon after the solvent has evaporated – this must be done within 30 minutes of the solvent application.

Concrete

Unsound material must be cut back to expose sound concrete. The surface must then be degreased to remove any contaminants.

Floor tiles and coverings

The under surface must be dry, free of contamination and lightly abraded. Some products, such as Vamac, are supplied to these requirements, but the under surface must be checked before the Wessex 310 epoxy is applied. If cloth-backed floorings are used, any release agent must be removed before bonding. If in doubt, degrease and abrade with 80 or 100-grit before applying the adhesive.
