Please Note: This product is mixed to order, so unfortunately cannot be returned. This does not affect your statutory rights.

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.

Application temperature should not be below 5°C or exceed 30°C and a relative humidity of 85%. Ensure tin is stirred thoroughly before and during application. This product is not suitable for spraying.

As a standalone product, usually for rough sawn timber such as cladding, decking, fascias and soffits, apply 3 coats. For joinery, such as doors and windows, apply as below: -

1. Apply 1 coat with the ProDec Trade Pro Bristle Blend Brush in a full flowing coat, laying off in the direction of the grain, using the minimum number of brush strokes necessary
2. Leave to dry for 24 hours
3. Finish joinery with two coats of Sikkens Cetol Filter 7 Plus
4. For best results, keep the interval between coats as small as possible, not exceeding 1 month but allowing each coat to dry thoroughly

Maintenance

For cladding and fascias and other surfaces treated with just Sikkens Cetol HLS Plus:

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

No, as this is a stain for timber, the stain would not be able to adhere to the plastic.

The Sikkens HLS is a very popular choice for log cabins and summer houses. For longer lasting results, try putting two coats of Sikkens Cetol Filter 7 Plus over this.
