Knotting

[Stefania]

Hi everyone,


I have a situation with my door frames. So, they are new frames and they are not primed. On the bottle of Knotting says that after I apply it on the nodes, I have to paint with oil based emulsion if I want to paint over with water based. Do I also have to sand the oil based before applying the water based. Isn't that true? I have a undercoat trade from Dulux that says I can use it on wood and for the top coat Eggshell from Dulux.


Thank you!

It says a "suitable" waterbased primer. I have had no problems using water based primers in the past.

BTW, I have never heard of "oil based emulsion"...

Thank you! I meant solvent based paint, sorry.

This is what it says on the back and that's why I was confused.

That is odd.

On their website they say

"For application to bare wood. Clean knots prior to priming/painting. To prevent discolouration of paint film. Use under oil-based and knotting-compatible water-based coatings."

Although I normally use pigmented shellac paints rather than dedicated knotting solution, I have never had any problems using waterbased undercoat/primers such as Dulux Trade or Leyland Trade. Ordinarily, I then apply two coats of Dulux Trade eggshell without issue.
