WHY IS A FINISH APPLIED TO WOOD?
|
INITIAL PREPARATION Filling cracks - PVA or cascamite mixed with wood dust producing a paste, which is then applied to cracks and gaps. Shellac - Supplied in stick form, in various shades. It is melted into holes / cracks in the wood with a soldering iron and then levelled, usually with a chisel. Wax sticks - useful when repairing scratches, nail holes or cracks. The stick is warmed up and when soft, pressed into the hole / crack. The surface is then levelled with glass paper. |
