    Additional information

    Surface Preparation

    New Timber: Degrease any exposed bare timber surface by wiping with a cloth dampened with methylated spirits. Certain timber species contain high levels of natural wood extractives or exudates and some softwoods can be highly resinous. Resinous deposits should be removed with a scraper. Any remaining residues should be removed using a lint-free cloth dampened with methylated spirits, frequently changing the face of the cloth. Allow solvent to evaporate fully before overcoating. The use of both eye and hand protection is strongly advised.

    Damaged or Decayed Timber: All damaged or decayed timber must be removed and replaced, cutting at least 25mm into sound timber. We do not recommend the use of wood hardeners. Secure any new spliced-in timber with non-ferrous fixings and fill all voids surrounding the splicedin area with the Componex WR Primer/filler system.


    • Apply the product in a full flowing coat, laying off in the direction of the grain, using the minimum number of brushstrokes required to produce an even finish.
    • Avoid overbrushing, which creates brushmarks and will reduce the protection afforded.
    • This initial coat should satisfy the porosity/absorption of the timber.
    • Carefully denib the first coat using a fine grade nylon abrasive pad or a fine grade (P240 or finer) wet or dry silicon carbide abrasive paper. Remove all dust.
    • Three coats of Cetol BL Decor should be applied, allowing a minimum of 5 hours drying time between coats or a two coat application onto a coloured coating such as Cetol BL Decor for protection.

    Clean Up

    Clean the brushes and equipment immediately with lukewarm water.
