Before embarking on finishing your wood cladding, it’s important to make sure that any old coatings are fully removed. If your wood cladding has not been finished with anything before then you can skip this step. However, if it has, you’ll need to remove it. Follow our simple guide to find out how to strip wood cladding.
Stripping off paint or oil from your wood before applying your choice of finish, you can achieve a much longer lasting finish. If you don’t strip your cladding beforehand, you run the risk of your new coating not penetrating or flaking off.
Wood cladding strippers essentially prepare your wood cladding for its new coating, improving both adhesion and penetration.
What kind of product you need to strip your wood, depends on whether you are trying to strip off oil, paint or other types of coatings.
Perform a ‘touch test’
Regardless of which type of stripper you’re using, prior to stripping your entire cladding, you should initially perform a ‘touch test’. In order to do this, you simply need to apply your stripper to a small area of your cladding and leave it. After a short period of time, try to scrub the edge to see if the coating is coming off. If it’s not, leave it a little longer and try again.
Record how long it took for the coating to lift off and then this is your ‘touch time’. As long as your surface is coated fairly evenly, you’ll know how long you’ll need to leave the remover on when you’re stripping the rest of your cladding.
A sample pot of stripper is a great way to do this. If you’re not sure what coating is on your cladding, a sample pot of Dilunett is a great place to start.
How to strip oils from wood cladding
If your cladding is covered in wood oil, we recommend using Aquanett to remove them. An exception to this is if your wood is already treated with an Owatrol penetrating wood oil. If this is the case then you’re essentially performing maintenance and so won’t need to strip and start again. If you’re working with a different previous wood oil though then it will need to go to allow any new finish to penetrate. This solvent-free wood oil remover not only restores the natural colour of the wood but also removes previously applied oil, including teak oil.
The gel-like consistency of Aquanett makes it a great choice for wood cladding, as it won’t ‘run away’ down vertical surfaces.
Using Aquanett is simple: just apply it to your cladding, leave it to work for a maximum of 5 minutes and then scrub your cladding with a stiff nylon brush, whilst rinsing it with water (the higher the pressure of the water, the better).
How to strip paints and opaque finishes from wood cladding
For paint-covered wood cladding, we’d recommend Dilunett.
Its gel-like consistency makes it great for vertical surfaces and it can strip up to 8 coats of paint in only 1 application. As it doesn’t dry, you can leave it on your cladding for up to 12 hours. Dilunett also removes varnish, waxes and most antifouling paint.
Simply apply Dilunett to your wood cladding, leave it to work and then rinse it off with water. While rinsing, be sure to scrub the wood in the direction of the grain.
Always neutralise your wood cladding
After stripping your cladding, you should apply Net-Trol. This will help to prevent the stripper remaining active in your wood cladding and is essential before applying your finish.
Please read all instructions on the product you’re using and ensure that you carry out any safety recommendations.
