Sikkens Cetol THB Plus

Sikkens Cetol THB Plus is a durable wood stain for use on interior and exterior windows and doors. Suitable for softwoods and hardwoods, with a low maintenance cycle of every 3-4 years. Perfect for use on its own or as a top coat with Sikkens Cetol HLS Plus, when a deeper colour is required or for any repairs.

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 application
4. Do not use on substrates or wood preservatives which have water-repellent properties, i.e. products or timbers that contain silicone or waxes

Previously Coated Timber

1. Abrade 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 all traces of 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

1. Damaged or decayed timber must be removed and replaced, cutting at least 25mm into sound timber. Make sure the wood is sanded back to a sound substrate
2. Continue application using Previously Coated Timer or Bare or New Timber methods as appropriate

Always do a test area before starting any project to assess product suitability and final finish. Follow the manufacturer's instructions on the tin at all times.

Sikkens THB Plus is ready-to-use from the tin. Do not thin. Only apply in temperatures ranging between 5°C to 35°C. Stir thoroughly before and during application. This product is not suitable for spraying.

1. Use 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. Seal new or bare surfaces with a first coat of Sikkens Cetol HLS Plus or with a thinned coat of THB Plus, thinning with 5 - 10% of white spirit
4. Apply 2 full coats of THB Plus on previously coated or suitably primed surfaces
5. Allow 16 hours to dry between each coat

Regular Cleaning

For regular cleaning, wipe wood surfaces with a lint-free cloth and warm water.

Repair

1. Lightly sand with a fine grade abrasive paper to keep splinters and rough edges away
2. If the timber has been stained, lightly sand but avoid sanding back to underlying stain
3. Remove all dust thoroughly and apply a first coat of Sikkens Cetol HLS Plus or Sikkens Cetol THB Plus in the correct colour
4. Apply a further coat of THB Plus to finish
