Sadolin Woodstain Review (Classic and Extra)

Updated Jun 3, 2024 | Posted Oct 5, 2021 | Product Reviews, Paints | 5 comments

Sadolin Woodstain comes as two separate products. The Sadolin Classic can be used on its own indoors. However, when working externally on new or bare timber, you should use Sadolin Classic as your first coat(s) to build up your desired colour, followed by a coat of Sadolin Extra to give your finish the UV protection needed for longevity.

Sadolin products are manufactured by Crown at their factory in Darwin. It is a popular trade brand, so you can purchase it from Crown Decorating Centre, online by clicking here, or several other stockists.

Sadolin Woodstain is available in various different colours. The Classic and the Extra are both oil-based products, however they also do a “quick-dry” wood stain which is water-based. I’ll pop a little section about Sadolin QD at the bottom of this blog.


My Sadolin Woodstain Review


OK, I’m almost 200 words into the review and I haven’t given my opinion on anything yet. Sadolin produce one of the nicest woodstains on the market!! Opacity is lacking a little bit, so if you’re recoating aged timber that has had a few knocks, it may be advantageous to dye any spots of bare timber with something like Colron prior to staining (Available at B&Q).

Other than opacity, everything else about Sadolin is fantastic. Even when you use the classic on its own, you are always left with a very rich and durable finish. Brush marks just seem to melt away, which is a Godsend on large flat surfaces such as doors. The finish is a lot nicer with Sadolin than you can achieve with other stain.


 Classic AND Extra on External Timber


There is a reason Sadolin tell you to use two separate products as part of a system on external timber, even though most other brands have a “one product does all” approach. Having one product to do everything means you need to compromise on something. You’re essentially asking that one product to build colour, have enough body to cover, be thin enough to level out, cope with UV, be flexible and even waterproof.

Sadolin does not compromise. The Sadolin Classic is there to have body, build colour and form a solid base. The Sadolin Extra adds depth, levels off beautifully and contains the UV protection. Both together will give you the best finish you’re ever likely to achieve using woodstain.

Another advantage of using Sadolin is the longevity of product and the protection it offers. As a decorator, I’ve been working in the same area for approximately 20 years, so I get to see how well each product lasts over time. I can tell you now, from my own experience that the two brands which last the longest are Sadolin and Sikkens. Nothing else seems to come close!! Nothing I’ve tried anyway.

There is one disadvantage of Sadolin Extra and that’s the drying time. You should only use this product outside and in good weather, otherwise it may still be tacky 24 hours after using it. This is an inconvenience when coating doors and windows as you won’t be able to close them until the stain is dry. It also means there’s more chance of being caught out by an unexpected shower and ruining your work!!

Sadolin Quick Dry Wood Stain Review


Water-based has a few advantages and disadvantages over oil, especially when it comes to stain, but that’s a completely different blog. Let’s review Sadolin quick dry wood stain. Adhesion is great on bare timber, or timber previously coated with water-based stain (I tend to avoid using water-based unless I know for certain the timber has never been stained with oil in the past).

Opacity is good and it is easy to hide brush marks. The finish and longevity are good for water-based, but not at the same level as oil. Ease of use is amazing!! This product just flies on, regardless of whether you are an amateur or professional.

Best Brush to Apply Sadolin Woodstain


There is one brush that stands out as the best for applying any oil-based stain, oil, or varnish. That brush is the Kana Tank. The brush itself has a natural fibre core made from hog hair, wrapped in synthetic outer bristles. This is designed specifically to hold onto thin materials like Sadolin Wood Stain.

The Kana Tank holds onto loads of material, allows you to work it onto the timber and manipulate it into all the corners. Nothing else comes close. Available online by clicking here.


Final Thoughts


Sadolin is a good quality trade brand which is underused by decorators. Their stains and varnishes are up there as the best on the UK market. They just seem to level of perfectly and leave you with a gorgeous finish that seems to last for years. Click here for more information or to see latest prices.

    Just spotted this. I made two fair sized Church gates made from 10yr old air dried oak. As instructed by the Church a wax oil finish was applied. What a cock up. All sanded off now.
    Just wondering if your reviewed products would be suitable?
    When you apply the Classic do you denib before applying the Extra? What grit? Do you wipe on wipe off to minimise thickness issue? How many coats? You refer to drying time issues. Given this time of the year I would have to coat indoors any idea how long before I could fit them in situ given temperature has dropped and raining most days? Sorry for the waft of questions. Cheers Steve

    I have been using sadolin for 40 odd years, noticed lately that the classic is now shiny as opposed to Matt, wax advised this was not the case but 3 tons later and they are all the same, I wanted a Matt finish to renew my home
