dulux trade wood primer by roller?

efunc · 1 Jul 2021

Hi all, I'm doing window frames in this oil based wood primer. The tin says do not use a roller, but I'm using a mix of both brush and smooth foam roller for speed. Should I be concerned? It seems fine to me, but what is the issue I'm not seeing? Is it that it doesn't get into the grain of the wood perhap?

thanks!

I should have thought window frames were too narrow to even consider using a roller.

Possibly a roller would cause bubbles.

4" roller. It's pretty good for the outer part or the frame and sills, but obviously not for the the rest. I fill in with a brush. I find it pretty smooth, and if you go over it again while it's drying gets good coverage. I'm not getting any bubbles either. I don't really understand the drawback right now. Obviously roller alone couldn't do it all though.

Does it really save much time. Even with a brush, once you've cut in the glass it's literally about 5 seconds to paint each middle section! Plus do you not have to cut in to the walls, sill etc anyway?
I mean, I don't think using a foam roller will harm anything!

yes agreed, I ended up using the brush almost exclusively since there is so much narrow beading and cutting in. However I couldn't see any actual problem with roller application in principle, so was wondering why the tin says "Application: brush only"?

It may be because some paints are sprayable and therefore more likely to just sit on top of the surface!

I agree with Chivas69

I think it is Dulux's way of saying do not spray the finish.

Looking at the TDS (see the link)- It looks like they are covering their behinds with regards to health risks associated with spraying the finish, rather than saying that spraying will compromise the longevity of the product.

Thank you all. I wish they would just say 'Do Not Spray' instead of "Application: brush only". I found that roller application, in some circumstances, is quick and consistent in terms of finish and coverage. But of course brushing is good too. At least I'm a bit more informed now. Cheers
