Sikkens Cetol HLS Plus can be used on its own or over-coated with Sikkens Cetol Filter 7 Plus. It is also suitable for undercoating surfaces prior to treating with Sikkens Cetol BL Opaque.

Perfect for use on softwoods, hardwoods, plywood, block board and particle board, claddings, fascias, architraves, timber frames, fences and sheds. Its properties make Sikkens Cetol HLS Plus eminently suitable for application to softwoods.

Please Note: This product cannot be used on substrates which have had water-repellent wood preservative or pre-treatments applied, i.e. products that contain wax, oil or silicon. It has been designed for use on smooth wooden surfaces only.

Timber to be treated should be clean, dry and free from any dust, dirt, debris and surface coatings such as paint or varnish.

Bare or New Timber

  1. Resinous deposits should be removed with a scraper
  2. Any remaining residues should be removed by wiping the surface with a lint-free cloth dampened with methylated spirits
  3. Allow solvent to evaporate fully before over-coating with Cetol HLS Plus
  4. When filling, be sure to use a designated wood filler, as general or all purpose fillers may not be suitable
  5. Do not use on substrates or wood preservatives which have water-repellent properties, i.e. products or timbers that contain wood oils or waxes

Previously Coated Timber

  1. Denib 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
  2. Remove any remaining sanding dust prior to coating with Sikkens HLS Plus
  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. Before applying Sikkens HLS Plus, make sure the wood is sanded back to a sound substrate.

Always do a small test area before starting any project to assess the colour, consistency and compatibility of the finish. Follow the manufacturer's instructions on the tin at all times.

Application temperature should not be below 5℃ or exceed 30℃ and a relative humidity of 85%. Ensure that the Cetol HLS Plus is stirred thoroughly before and during application. This product is not suitable for spraying.

  1. Apply HLS Plus with a good quality, long haired, natural bristle brush
  2. Apply in a full flowing coat, laying off in the direction of the grain, using the minimum number of brush strokes necessary
  3. Leave to dry for 24 hours
  4. Apply 2 finishing coats of Cetol HLS Plus
  5. For best results, it is necessary to keep the interval between applications of these coats limited, not exceeding 1 month

Once dry, for extra protection this product can be over-coated with Sikkens Cetol Filter 7 Plus.

Regular Cleaning

Treated surfaces can be wiped over with a dampened lint-free cloth and warm water to clean and dust.


  1. Lightly sand with a fine grade abrasive paper to keep splinters and rough edges away
  2. Repair defects with Sikkens Cetol HLS Plus in the appropriate colour and apply one full coat of Cetol HLS Plus overall

Professional product by Steve Batchelor

This is the top coat to the 7 plus and is easily as good. As with the 7 plus, if you want a job done right, use this, if you are happy to keep redoing the job then buy something cheap - there is loads of stuff out there. I dont have time to keep refinishing jobs I have finished once so I buy the good stuff.

Easy to apply and covers well by Nigel Williams

Goes further than you think, 5l covered my cabin and a litre to spare on bare pine, BUT a second coat is needed for full protection and the colour does darken with second coat (light oak). For me , one of the best out there at a reasonable price.

Easy to apply by Paul Alderton

Bought to preserve timber of a log cabin/summer house. On application the pine colour is a little bright and hopefully will tone down with time. It is too early to assess how good a preservative it is.

Quality Product by J Riley

I only use this product now for all my outdoor wooden items - garden furniture, gates, fences etc. Its easy to use brush on dries relatively quickly. Brushes can be quickly washed in soapy water. Brush may remain slightly oily from the product I would not use the same brush for gloss or emulsion but that's not a problem!! It maybe more expensive than other available products but it does the job 100% and lasts a long time preserving the life of the wood

The Best Woodstain Available by Simon

Combined with Sikkens Cetol Filter 7 Plus as a top coat this is the best woodstain available. I've used it on my house for external windows and doors and for exposed timber on a sea going open boat. Easy to apply, provides good protection and lasts for years.
