Which wood grain filler?

[EagerBeaver71]

Hi, I have a tabletop which needs the grain completely filling as I will be spray painting the top black enamel (Non-waterbased). I have used builders bog on the top in places where larger holes were but have run out of that stuff and need a better alternative.

Advice and suggestions most appreciated.

Clean out all the builders bog (it doesn't stick well to timber...it really only sticks well to some plastics) and use Timbermate wood putty or marine epoxy (the larger the hole, the more I'd recommend epoxy).

Hello again Splinter, The bog filled some deep holes on fiberboard, the holes were caused when taking the cabinet apart and some of the laminate/vaneer got pulled off. Wont it stick at all to the fibers at all?, I'm asking this because it would take me ages to get all the bog out and some of the holes are pretty deep and the bog is like concrete now

It sticks, but it's one of those 'no guarantees' type things. Cracking at edges is always a possibility; a lesser possibility with MDF/chipboard (as those are a little more dimensionally stable and the structure of the materials can give a better grip) but compared to other options....lets just say it's like comparing a building made of mud brick to one made from reinforced concrete.

And if you're already through your first tin of bog...you've hit the 'oh, it would have been cheaper to buy a piece of MDF and have it cut to size' point.

So before proceeding further...buy a piece of MDF and cut it/have it cut to size. Even if you have to laminate two pieces of 12mm to get 24mm thickness, or 12mm and 18mm to get 30mm (or whatever) it'll still be cheaper and less work to prep for paint than mucking around with multiple containers of bog and trying to get a flat surface on woodgrain for paint!

Thanks for you're advice splinter, I wish I had spoken to you sooner as it is costing me a fortune at the moment...
