JOHA® Antique stain 421 - 250ml
Stains # 421 - antique gray-brown are ready-mixed oxidation stains. After application, the color changes under the effect of air and daylight from being colorless to antique gray-brown. This stain are applied exactly as described below. Once the required colour has been reached, gently sand with a fine sandpaper and apply 1 coat of basic varnish. This prevents further modification of the color. Ideally, one should carry out a test of stain and varnish on the same wood to see what the final result will be, since the colours will vary with different types of wood. This stain particularly draws out timber rings.
Stains and primers
If the unfinished instrument is to have a beautiful basic color, it should be stained before varnishing. But since the hardness of wood can vary, thus absorbing the stain unevenly, it is recommended that the basic instrument should be pre-treated first to ensure that the color is attractively even.
Instructions for pre-treating the wood
Dissolve about 30g of gelatin powder in a litre of warm water and then heat until the solution is clear and thin. Apply the warm solution evenly with a bristle brush, leave to dry completely and sand down very carefully with a fine sandpaper. The various stains described below can then be applied.
