For the best results, ensure surfaces to be primed are clean, dry (new surfaces
particularly must be fully dry) and free of dirt, grease or wax before treating. Take extra care during surface preparation of pre-1960s painted surfaces as they may contain harmful lead.
Previously Painted or Varnished Wood
- Clean off any wax polish, grease or finger marks with methylated spirit or a dedicated wax and polish remover
- Remove all defective or poorly adhering paint or varnish
- Rub down thoroughly along the grain of the wood to provide a 'key'
- Use 'wet' methods where possible
- Wipe off with a damp, lint-free cloth to remove all sanding dust
New or Bare Wood
- Any surface defects should be filled with an appropriate wood filler
- New or bare surfaces must be rubbed down with a suitable grade of abrasive paper
- Remove all traces of sanding dust with a damp, lint-free cloth or vacuum cleaner
- If required, clean and de-grease the surface by wiping over with white spirit
- Treat any knots in wood with an appropriate knotting solution
