ERECTION, INSTALLATION, APPLICATION
A. Staining Procedures:
1. Color mix stain to match original.
2. Apply stain to all bare wood surfaces with a stiff flat bristle brush.
3. Allow stain to set as required for proper color match as determined by testing process.
4. Wipe off excess stain by rubbing parallel to the grain with a soft, dry cloth.
5. Apply one (1) coat of sanding sealer rub with 0000 steel wool and wipe with a tack rag. (May not be required, test during preparation of sample areas.)
B. Finish Coating:
1. Make sure that surface is clean, level and free of defects.
2. Rub with 0000 steel wool and wipe with a tack rag.
3. Apply a minimum of three finish coats. Brush on lacquer using a wide, moderately full brush to flow a continuous, wet coat onto the surface with minimum of retrace or back brushing - preferably none. Work area small enough so that by working with long, fast, continuous strokes, each succeeding stroke works against the wet edge of the last stroke. A dry tack rag moving ahead of the brush will help to keep the surface dust free.
4. Allow each coat to dry at least two, preferably four hours.
5. Sand with 4/0 to 6/0 paper, only if necessary to remove defects and level surface for next coat.
6. Before adding the next coat, vacuum and wipe the surface with a dry tack rag in order to remove all grit and dust.
