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.Initial Procedure Ensure product is thoroughly stirred before and during application, otherwise sheen and colour variations may be experienced.
Cetol HLS plus is supplied ready for use. Do not thin.Applying the product For best results use a good quality, long-haired, soft bristle brush. On new work, where practical, the initial coat should be
applied all round prior to fixing. P ay special attention to any areas of exposed end grain, tops and bottoms of doors, and
undersides of cills.The product should be applied in a full flowing coat (working well into joints, and ensuring end grains or sawn timbers are saturated with product). Excess surface material should be re-distributed after 5-20 minutes (depending on conditions), using a dry brush (which should be periodically dried with a lint-free cloth) and the minimum number of strokes required to produce an even overall colour. This ensures that the first coat satisfies the porosity/absorption of the timber.
Allow a minimum of 18-24 hours drying time. Where appropriate (e.g. for joinery items such as windows and doors), the first
coat should be carefully 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. Do not break through the surface coating. Remove all dust.Cetol HLS plus should be applied in a full flowing manner in the direction of the grain, using the minimum number of brush strokes necessary to produce an acceptable finish. Avoid overbrushing, as this will reduce the protection afforded.Subsequent coatings should be applied as soon as possible after the previous coat has dried, but no sooner than 12-24 hours, in order to provide full protection. In any event this period should not extend beyond three months, otherwise additional preparation and coats may be necessary. If applied to exterior timber and the contract is of long duration, it is suggested that a further coat be applied prior to handover to make good any weathering during the construction period
