Cetol Filter 7 is an exterior woodstain for windows and doors either as a one-coat maintenance application for existing woodstain systems, or two coats over a base stain of Cetol HLS on new or bare timbers. Its advanced UV light absorbers provide superior protection from the damaging effects of sunlight on timber.
Ensure timber surface is suitably prepared, clean & dry, with dust, dirt, wax and grease removed and allowed to acclimatise to its end-use environment. Moisture content should not exceed 18% prior to coating
