Painting over wood knots

Question

Do I need a special paint to stop wood knots showing through or is a primer good enough?

Mark · Answer

Hi, you need to purchase a product called "Knotting solution"

You apply it to all knots on bare wood to stop the visual signs penetrative through the undercoat and gloss

Cheers

And then paint as required

You will need to get a Notting solution you can get it from pretty much any hardware shop or screwfix. If your painting it I would go with a shellac based primer like zinser bin give 2 coats and youll be good to go

You need to buy a solution called knotting. Paint over knots, leave to dry for the day, tgen paint over with wood primer and top coat.

Primer is okay but there is a material called ‘knotting’ which is the best! If not Zinsser is also good

Mark · Answer

Patent knotting x 2 coats before priming
Use a fetch or a cloth & dab it

Jamie · Answer

Best to use knotting solution, I use a wrag and dab the knotting over each knot,..if you use a brush you will get lots if runs you will need to sand out

Hello

I would always recommend a specialist wood knot paint. A lot of primers will say they have stain block in them but if a wood know ‘leaks’ it will show through even with the best primer. Ro seal do a good wood knot block primer but I’ve had mixed results with it, I always not use a knot sealant before using a stain block primer.
Hope this helps!
