Filling Pores There are two ways to fill the pores.On close grained wood you can use the finish itself.Essentially you apply as many layers (or 'coats') of finish as needed to fill the pores, either sanding between each layer, or sanding after applying the last layer of finish.
On open pored wood your best bet is to use a paste wood filler.There are two kinds of fillers, one for film finishes (shellac, lacquer, varnish, polyurethane) and one for water based finishes.Keep in mind that you shouldn't use a filler under a penetrating finish (tung, linseed, wiping varnish, or oil/varnish blends such as Danish oil), as they don't cure hard enough.
For a detailed discussion of pore filling you might want to read the ultimate reference book: Understanding Wood Finishing by Bob Flexner (ISBN 0-7621- 0191-1).Filling Is Not SealingYou may come across a product called a sanding sealer.
This isn't the same thing as a pore filler.When you apply your first coat of finish to a wood surface, the wood fibres will swell, giving the surface a fuzzy texture (referred to as raised grain).Before you apply subsequent coats of finish you need to sand off these fibres.
