Timber surfaces to be treated with Sikkens Cetol Filter 7 Plus must be clean, dry and free from surface dust, dirt, wax and grease. Wood to be treated should be allowed to acclimatise to its end-use environment before treating. Moisture content of the timber should not exceed 18% prior to coating.

Bare or New Timber

  • Degrease any exposed bare timber surface by wiping with a cloth dampened in a suitable solvent
  • Resinous deposits should be removed with a scraper and any remaining residues should be removed using a lint-free cloth dampened with a suitable solvent
  • Allow solvent to evaporate fully before over coating
  • The use of knotting agents is not recommended as they are not always fully effective in 'sealing in' resin, and adhesion of coatings can be impaired
  • If using a wood filler, ensure that it is one that is specifically designed for use with timber, as general or all purpose fillers may not be suitable
  • Only use non-ferrous screws, nails and fixings

Previously Coated Timber

  • Base stained joinery should be denibbed 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, ensuring not to break through the surface coating
  • Remove any remaining sanding dust prior to coating with Cetol Filter 7 Plus
  • To ensure optimum durability and uniformity of appearance, Sikkens recommend a coat of Sikkens Cetol HLS Plus prior to finishing
  • Where necessary, stop with tinted putty
  • 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

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. Sikkens Filter 7 Plus is ready to use straight from the tin and does not require thinning.

Stir thoroughly before and periodically during application to ensure a consistent finish. Only apply at temperatures ranging between 5℃ and 35℃ and a relative humidity of no more than 85%.

  1. Apply 2 coats of Sikkens Cetol 7 Plus with a good quality paint brush
  2. For best results, it is necessary to keep the interval between application of these coats as short as possible

Repair any color defects with Sikkens Cetol HLS Plus or Sikkens Cetol Filter 7 Plus in the right colour and apply one further coat of Cetol Filter 7 Plus overall.

Flows beautifully off the brush and looks elegant by Paul Eedle

An intelligent alternative to traditional varnish. I use it extensively on my 1907 Cornish fishing boat to protect the wood of masts and spars. It's easy to apply because it flows smoothly off the brush and needs far fewer coats than traditional varnish - two instead of six. It looks elegant when dry, not as hard a shine as varnish but an attractive gleam.

The paint was easy to apply and coverage was good by Michael Palframan

I bought this product on the recommendation of the guy who supplied the timber. I have used it on some new Douglas fir to be used as barge boards replacing timber that has rotted. I applied two coats each of base and finish coat and the colour match is close to the rest of the Douglas fir window frames nearby. The real test of course will be in several years time after the sun rain and frost have done their work. All I can say at this stage is that I am happy with the results so far.
