Filling nail holes and missing knots in wood thats to be painted

Ive just put up a load of tongue and groove style thin wood paneling in a bathroom, that im going to be painting a thick light grey, the grain isn't likely to be seen and nothing is to be stained.

ive pushed each nail below the surface so its not seen and id like to fill in the dinples left and the rest of the imperfections in the wood.

im wondering what's best to use, wood filler? caulk? something else?

I'm going to swing by B & Q on the way home to pick up whatever is recommended.

Thanks

 

fine wood filler.

 

White filler is fine, but any large missing knots might be better with actual wood filler because it doesn't shrink. But it can be done with white filler (typically you do it once, wait for it to shrink and crack, then go over it again). Caulk is the wrong stuff.

 

ok so wood filler sounds like the product, something like this ok?

Yes that's fine. A lot of people like car body filler too, if you happen to have some already.

 

no unfortunately not, Thanks chaps!

 

For wood your best bet is 2-pack wood or car body filler. One part wood filler has a tendency to shrink under the surface whilst plaster or cellulose decorator's fillers have a nasty tendency to crack or get pushed out as the wood moves with changes in the seasons. About the only other fillers worth a shot on timber are the old-fashioned Brummer fillers and, believe it or not, traditional putty - both of these dry really hard and are remarkably tenacious in their holding power

 

what kind of brands are two pack? is that one that has a seperate hardener in it or does it mean something else?

 

Yes.
