Overview
Overview
Back
Sikkens Cetol Filter 7 is a medium build, solvent-based woodstain for doors, windows and other exterior joinery. Formulated with UV absorbers to give wood superior protection against sun damage. Being moisture vapour permeable, it allows water vapour to escape and not get trapped under the surface.
Sikkens Cetol Filter 7 was previously called Sikkens Cetol Filter 7 Plus. The formulation has remained unchanged.
Preparation
Preparation
Back
Timber surfaces to be treated must be clean, dry and free from dust, dirt, wax and grease. The wood should be allowed to acclimatise to its end-use environment before treating. The moisture content of the timber should not exceed 18% prior to coating.
Joinery should be treated with a base coat of Sikkens Cetol HLS Plus which Sikkens state will provide 5 years of protection from weathering.
Application
Application
Back
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. This product is ready to use straight from the tin and does not require thinning.
Only apply at temperatures ranging between 5°C and 35°C and a relative humidity of no more than 85%. Stir thoroughly before and periodically during application to ensure a consistent finish.
- Apply 2 coats of Sikkens Cetol Filter 7
- For best results, it is necessary to keep the interval between application of these coats as short as possible
- Allow to dry fully before application of the next coat

- If required, fill any holes with a suitable wood filler
- Colour any defective areas after preparation with the matching colour of Sikkens Cetol HLS Plus
- Re-apply one coat of Sikkens Cetol Filter 7

Can Filter 7 be used as a stand-alone product?
I have received two tins of Sikkens but one looks different to the other. One is orange and one has a purple band on. Are they safe to use?
No, the Sikkens Cetol HLS Plus must be applied to bare wood first. If this product is applied directly to bare wood, then it will appear patchy as it is a higher build wood stain.
I have received two tins of Sikkens but one looks different to the other. One is orange and one has a purple band on. Are they safe to use?
Absolutely, in 2024 Sikkens have rebrand this product. They have assured us that the formula inside the tins are identical.

Best stain going
Got to be about the best outdoor stain available... excellent coverage and 7 year retreatment plan. What's not to like?
Gary Haines. Walnut - 010, 2.5L (05/11/25)
Very good
I didn’t personally stain my door, but the painter who applied it, was very pleased with how well it went on the wood. The end result is excellent and I am very happy with the final finish.
Mrs A Scrivener. E3.18.21T, 1L (04/11/25)
Good Half way between a stain and paint
Lots of large outbuildings with cedar cladding to re-stain after 5/6 years when they were originally built . I probably left it a little too long before re-staining as the original Cetol was starting to peel. Where the peeling was minimal (North facing walls) the Cetol Filter 7 went on like a dream and looks as good as new. The other walls which had some peeling due to the sun might need another coat in the spring. I diluted it with white spirit 8:2 (8parts Cetol, 2parts white spirit) that seemed to flow on the brush and adhere to the wood better than straight from the tin. Time will tell how good it is!
David Lindsay. Light Oak - 006, 5L (31/10/25)
I HAVE PREVIOUSLY USED
EXCELLEND PRODUCT THAT DOES THE JOB , LOOKS GOOD, EASY TO APPLY AND KEEPS THE WATER OUT. HARD WEARING
Stella Heap. Light Oak - 006, 2.5L (08/10/25)
It is very good indeed
Sanding down before renovation can be a problem as it leaves light and dark patches. Do not leave too long between renovations.
