Wood Fillers

by Maya Palmer

Wood fillers close up the pores of coarse, grained wood and produce a smooth, hard surface on which finishing coats can be applied. The decision whether to use them or not is up to you. Fillers should be used if a finish with a natural-wood look is desired. Close grained wood seldom requires a filler; sealer and top-coat are sufficient to pack the small 13 Ares, particularly if a pigment stain is ed.A paste filler containing silex (finely ,powdered quartz) is better than a liquid. he paste will pack the wood grain more tightly and help the topcoat adhere more firmly.

In general, the wood filler should match or be slightly darker than the stain used on the wood. Buy it in the natural tone and tint it with oil pigments. The filler should be applied both with and across t he grain eit her before or after staining. If it is to be applied after, first seal the surface with a coat of thinned shellac. Thanks for reading this page on wood fillers.

Sealers; A sealer is a coat of diluted lacquer, shellac, or varnish that is applied over a slain or filler. It prevents bleeding and improves adhesion between the topcoats .ind undercoats. A sealer may also be used as a primer over bare wood to re-strict penetration of a succeeding coat. Shellac is an excellent general choice; it dries fast and provides good adhesion the case of wood treated with oil stain, there is no option; only shellac should be used. Thin the shellac by mixing one part shellac with eight parts denatured alcohol. It varnish is to be used as a sealer, mix it with an equal amount of turpentine; if lacquer is to be used, mix it with .6 n equal amount of lacquer thinner.Before applying a sealing coat, be sure the surface is dry and free of dust. Brush on the sealer wit h the grain. Let it dry thoroughly, then smooth lightly with No, 1/0 steel wool. More on wood fillers coming soon.
