Ensure the timber surface is suitably prepared, clean and dry, with dust, dirt, wax and grease removed, and allowed to acclimatise to its end-use environment. Moisture content of the timber should not exceed 16% prior to coating with Sikkens Rubbol BL Primer.

Bare or New Timber

  • Degrease any exposed bare timber surface by wiping with a lint-free cloth dampened in a suitable solvent
  • Allow solvent to evaporate fully before over-coating
  • Any resinous deposits should be removed with a scraper
  • 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
  • Where necessary, fill 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.

Excellent product, as expected the perfect partner for the topcoat by Andrew Farmer

Easy to use (can be a bit messy) as it flows well, and provides an excellent key for the topcoat that I am using (Sikkens Rubbol BL Satura). Ensure that the preparation instructions are closely followed. First time that I have used this product, although I have used the topcoat (previously mentioned) on several previous occasions.

My go to primer for woodwork by Jonathan

Excellent opacity and levelling, high adhesion and flows well. One of the best water based primers available

Excellent product by Jonathan Congreave

I am using this product in a new build. It is easy to use and covers well with the right brushes. I decided to use this product as It does not yellow - I have used it before and have been very pleased with the results. It needs to be applied sparingly as it does not spread in the same way as oil based paint - putting on too much creates runs.
