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

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

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.

  1. Apply 2 coats of Sikkens Cetol Filter 7
  2. For best results, it is necessary to keep the interval between application of these coats as short as possible
  3. Allow to dry fully before application of the next coat

Aftercare

Maintenance

The finish should be inspected yearly to check for any surface defects or damage as a result of weathering. If required, areas of wear or damage can be rectified by carrying out the following.

  • 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

FAQ

Can Filter 7 be used as a stand-alone product?

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

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!

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.

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.

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.

It's brilliant. Easy to apply and lasts ages

I've had sikkens on my softwood garage doors for 30 years and they are still going strong and rot free. Same on my teak boat for 20 years. Re coat every 3 to 4 years and you are good to go

An excellent product, when used with Sikkens cetol HLS, on new wood...

I used Sikkens cetol HLS and Cetol Filter 7... on a new build in 1994, all external wood was treated on all sufaces inside and out, before fitting, facia and soffit boards are still in excellent condition...@2026...

LAST COAT LASTED JUST UNDER 7 YEARS

I’ve used this product before and bought it again because I know how good it is. Last time I used it was just under 7 years ago. I think it’s guaranteed to last 5 so it lasted longer. This time I sanded/scraped all the old paint back to bare wood. I gave the wood 2 coats of the recommended ( Sikkens Cetol HLS Plus ) and then 2 coats of ( Sikkens Cetol Filter 7 ) I must say it looks beautiful and I know it will last 5 plus years. Also, the side of the lodge that was painted is in the sun for around 7 hours during the summer days.

Fantastic product, great results

Love the way this product goes down, really nice to apply. Colour from the chart is not wholly accurate but I suppose it depends a lot on the material it's being applied to. Great results and worth the money.
