A superior UV resistant oil based coloured finish for windows, doors, fascias and cladding. It remains flexible as timber moves and provides extra protection for timber exposed to maximum weathering. Not suitable for any walk on surfaces or seating. Must be used over a priming coat of Sikkens Cetol HLSe.

Ready to use with no need to thin. Stir thoroughly before use. Final colour will depend upon timber type, previous treatment and the number of coats applied. Ensure timber moisture content is below 15%. Do not apply in temperatures below 5℃ and above 35°C, in damp conditions (when relative humidity is above 85%), or if rain or dew is likely before the product has dried. If using more than one can, it is advisable to mix them together in a larger container for colour consistency. New bare timber needs sanding, cleaning and priming with Cetol HLSe. At temperatures below 10°C and when used internally with limited air circulation, the drying process will be delayed. On correctly prepared surfaces, apply two coats of Cetol Filter 7 Plus evenly with a good quality brush along the grain, avoiding overlaps. Allow 24 hours between coats.
