Overview
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.

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.

A Very good product
I've used this preservative and finish for 15 years on a garden workshop and have been very impressed with its properties. Easy to apply and is very resilient against the weather. A relatively small amount has excellent coverage which makes it good value
Keith Rayner. Dark Oak (009) D9.54.32T, 2.5L (05/09/26)
A beautiful product
Using a high quality product is something I've never done till now. It was an absolute treat to use something that didn't come from the bargain bin.
It's a bit like getting on a plane and turning left into first class rather than turning right and fighting your way to the cheap seats at the back of the plane. Recommended!

Good brand good product
I have used Sikkens for many years - window frames doors and gates. I haven't come across anything better for protecting and maintaining the look of the wood.
Bob Goodchild. Walnut (010) C6.16.11T, 1L (03/09/26)
Excellent for treating timber
A quality product which is dearer than similar products but is far superior and goes a long way when applying. Worth the extra cost.
Mike Horton. Mahogany (045) B8.29.15T, 1L (03/09/26)
Sickens is the best you can get
I have been using Sikkens for 40 years. Expensive but offset by its long lasting quality and protection life compared with other makes, unbeatable.
Anthony Twamley. Walnut (010) C6.16.11T, 1L (28/08/26)

Used on a hardwood bay window that gets full sunlight. Also used on a faded composite door. That too works
