Tried a few products on my 20 year old cabin/summerhouse.over the years and this is by far the best. Great coverage and a good oak colour that covered well even on silvered/grey timber. Arrived next day in great packaging making it virtually impossible to spill. Will definitely be using again.

We have used this product on all our windows, doors and all other exposed external timbers ever since building our house approximately 22 years ago.On the windows & doors, we followed up with 2 coats of Sikkens Filter 7 & we follow up with a light coat every 2 or 3 years.The windows & doors, have proved the test of time & still look brilliant today.

Sikkens produce a wide range of wood stains, so it is difficult to know which one to use without personal advice. As I bought this stain through eBay during the "lockdown", this was not possible. The can arrived without a product sheet, and few instructions are included on the can. On checking the Sikkens website, a full range of product sheets are available, but the one for Cetol Filter 7 plus has been withdrawn! I have used Sadolin Classic extensively as a wood stain, and this is thin to apply and penetrates deeply into soft wood and deteriorated hard wood. The job in hand was restoration of previously varnished oak french windows. Although the Cetol F7+ is clear so that the underlying wood grain remain visible as advertised, I was surprised to find the product ... MoreSikkens produce a wide range of wood stains, so it is difficult to know which one to use without personal advice.

Although the Cetol F7+ is clear so that the underlying wood grain remain visible as advertised, I was surprised to find the product has a consistency more like treacle (slightly diluted). It does give a lovely finish with light oak coloration, but I don't know how deeply it penetrates, especially where the oak has weathered. I have therefore taken to applying a wood preservative first. I will then apply the Sikkens after the preservative has thoroughly dried. A final point is that without product literature, I don't know how many coats I should apply - only that brief instructions on the tin state "do not sand between coats"!

First time I've used Sikkens on my Iroko gates. Hoping I don't have re-apply more regularly than every 3 years. I applied it after removing most of the previous product, Osmo oil 420 which couldn't cope with the horizontal surfaces on the back of the gates. After 3 months it seems to adhered well.. Still prefer Osmo oil 420 as it is colourless. But Osmo is no good of horizontal surfaces. So far very happy. The only downside is the colour . Light Oak is a little too yellow for my taste.
This stain, although a little pricey, is excellent for exterior woodwork and provides good protection as well as a very smart finish. If used with the Sikkens Cetol HLS Plus as a base coat the results are even better. It is quite runny and care has to be taken when applying. I would not use anything else now.
The first time I've used this product, I usually just use the HLS Plus on it's own and that is very hard wearing, but thought I'd splash out on this for the topcoat and so glad I did. It has given a fantastic finish which really brings out the grain and looks like it will easily last 5 years. Made our oak doors look fantastic. Well worth the money, and great price and fast delivery as always.
Use this stain to finish off my Pallet Tool storage project. The wood surface has sanded first with 60 grit and finished in 120 grit. I applied two coats of Sikkens Mahagony using a brush. The product was easy to apply with a pleasant odour. The finish was superb. The second coat produced a higher gloss finish. Grain of the timber still visible and apparent. Follow the full project on Youtube through Ash Applications.
I've used this for many years and always been impressed with it's longevity, great on soft and hard wood, breathable, never cracks or blisters and when it needs a maintenance coat, just a light sand and it's ready. So easy to look after, love it. Can use it for first coats as well as top coat so only need one tin for the whole job, although the Filter 7 Plus makes an impressive job look fantastic.
I find this Sikkens cetol filter 7 plus easy to apply by brush to give a really good long lasting professional finish to all my timber projects be it a softwood or hardwood project. I have been using this product for many years now with success every time.
Excellent. Living by the coast we get a lot of rotten weather. Rain, hail and excessive winds. The Sikkens 7 Plus handles all of this on our hardwood.
