Sikkens 1Ltr THB Topcoat Woodstain
A medium build, solvent-borne, semi-transparent woodstain for use as a finish over Cetol HLS plus on exterior softwood and hardwood joinery. Cetol THB may also be used as a maintenance treatment for joinery previously treated with Cetol Filter 7. Cetol THB is not suitable for use on decking or other areas subject to high levels of abrasion.
Preparation: 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. The moisture content should not exceed 18% prior to coating. Degrease any exposed bare timber surface by wiping with a cloth dampened with a suitable solvent. Certain timber species contain high levels of natural wood extractives or exudates and some softwood can be highly resinous. Resinous deposits should be removed with a scraper. Any remaining residues should be removed using a lint-free cloth dampened with a suitable solvent, frequently changing the face of the cloth. Allow solvent to evaporate fully before overcoating. The use of both eye and hand protection is strongly advised. We do not recommend the use of “knotting agents” with translucent finishes as they are not always fully effective in “sealing in” resin, the presence of knots is often highlighted and adhesion of coatings can be impaired. When filling, be sure to use fillers specifically designed for use with timber. General or all purpose fillers are not suitable, particularly on external areas, as they cannot cope with timber movement and work loose.
Product Application: Ensure product is thoroughly stirred before and during application, otherwise sheen and colour variations may be experienced. Cetol THB is supplied ready for use. Do not thin. Cetol HLS should be used as a basestain for joinery items prior to coating with Cetol THB. For best results use a good quality, long-haired soft bristle brush. The product should be applied in a full flowing coat, laying off in the direction of the grain, using the minimum number of brushstrokes necessary to produce an acceptable finish. Avoid overbrushing, as this will reduce the protection afforded. Apply to a minimum wet film thickness of 60 micrometres. Conditions - Do not apply if there is a risk of rain, or when air/substrate temperatures are below 5ºC or above 30ºC during application or drying periods. Protect from frost and rain until dry. Failure to meet these requirements may adversely affect the drying, visual quality and durability of the finish. Two coats of Cetol THB should be applied, allowing a minimum of 16 hours drying time between coats. On new work, where practical, the first coat should be applied all round prior to fixing. Pay special attention to any areas of exposed end grain, tops and bottoms of doors, and undersides of cills. The second coat should be applied to all exposed surfaces, as soon as possible after the first coat has dried, but no sooner than 16 hours.
Cleaning equipment: Clean brushes and equipment with a proprietary brush cleaner immediately after use. If spilled, Cetol THB may be removed immediately while still wet, using white spirit.
Storage: The can should be resealed after use and stored tightly closed to prevent evaporation of the product and entry of air. Avoid the inclusion of a greater proportion of air to the product. It should be noted that even if there is a higher proportion of product to air in the container, once opened the shelf life of the product is unpredictable. Store in cool, dry, frost-free conditions.
