Sikkens Cetol BL Primer must be applied in accordance to the manufacturers instructions on the back of the tin. For further information relating to Sikkens Primer and its application, refer to the relevant product data sheet from Sikkens.

Ensure timber surfaces to be treated are suitably prepared, clean and dry, and free from any dust, dirt, wax and grease. Allow timber to acclimatise to its end-use environment. The moisture content of the timber should not exceed 18% prior to coating.

Bare or New Timber

  1. Degrease any exposed bare timber surface by wiping with a lint-free cloth dampened with methylated spirits
  2. Allow solvent to evaporate fully before applying Sikkens Cetol Primer
  3. Any resinous deposits should be removed with a scraper
  4. The use of 'knotting agents' particularly on exterior work, is not recommended as they are not always fully effective in 'sealing in' resin, and the adhesion of coatings can be impaired
  5. When filling, be sure to use a designated wood filler, as general or all purpose fillers may not be suitable
  6. Do not use on substrates or wood preservatives which have water-repellent properties, i.e. products or timbers that contain wood oils or waxes
  7. Only use non-ferrous screws, nails and fixings

Previously Coated Timber

  1. Denib (lightly sand) using a fine grade nylon abrasive pad or a fine grade (P240 or finer) wet or dry silicon carbide abrasive paper, in the direction of the grain
  2. Do not break through the surface coating, and remove any remaining sanding dust
  3. Where there is localised damage, or deterioration has occurred as a result of exposure of the factory coating for longer than 3 months, affected areas should be thoroughly sanded back to a sound substrate

Old Timber

  • Damaged or decayed timber must be removed and replaced, cutting at least 25mm into sound timber

Always do a test area before starting any project and follow the manufacturer's instructions on the tin at all times.

  1. Apply one coat of Cetol BL Primer with a good quality synthetic brush or microfibre roller
  2. Allow 3 hours to fully dry

Once dry, Sikkens Cetol BL Primer can be finished with 2 coats of Sikkens Cetol BL Opaque.
