| Wood Work Surface Preparation |
| Soft wood | Hard wood | Ply wood |
Soft woods: Surface preparation of wooden surfaces is vital as it ensures good long lasting adhesion. Ensure the wood is dry. Prime all joints, tenons, tongues, grooves and meeting surfaces during assembly to prevent subsequent absorption of moisture if the joints etc. open after decoration. Sandpaper smooth and finely round-off sharp edges. Dust off, treat all knots and resinous parts with Wood Primer and allow to harden thoroughly. Large and resinous knots should be cut out, plugged and planed to produce a smooth surface. The Primer should be applied liberally and brushed well into the surface. Pay particular attention to end grain. Very porous end grain should be treated with a second application to prevent moisture penetration.  Hardwoods:  Sandpaper smooth and finely round-off sharp edges. Dust off. Oily timber should be thoroughly wiped clean with a cloth dipped in White Spirit and allowed to dry. Primers should be applied liberally and brushed well into the surface. Pay particular attention to end grain to prevent moisture penetration. Plywoods:  Ensure the plywood is dry. Thoroughly sandpaper and dust off. The primer should be applied liberally and brushed well into the surface in the direction of the grain. To obtain a smooth and high-class finish the grain, pores and imperfections of the plywood should be filled with an oil based wood filler. Rub down with fine abrasive paper and dust off prior to painting. |
