When the desired quality of polish has been secured in either the satin or highly polished finish, the surface is slushed off with water and a wet chamois, and when dry is thoroughly cleaned with a soft cloth and naphtha or benzine. For a high polish equal parts of olive oil and denatured alcohol can be rubbed in with a cloth pad. The oil can later be "spirited off" as will be explained under French polishing. Although varnish has been traditionally brushed on, there is available a type manufactured especially for spraying. Ordinary varnish is usually thinned with turpentine for spraying, with as much as 25 per cent added for suction guns on small compressors. Natural Finish Varnish Schedule. 1. Sand with 40 garnet paper and dust. 2. Shellac washcoat (1 part shellac6 parts alcohol). Dry. 3. Sand with 40 garnet; dust. 4. Fill and wipe opengrained woods. Dry. 5. Sand with 30 paper; dust. 6. Shellac washcoat (14.). Dry. Shellac mixing lacquer preferred. Optional: Varnish (6 parts varnishi part turpentine.) 7. Sand with 50 garnet; dust. 8. Pale Rubbing and Polishing Varnish. Dry. 9. Sand with 60 waterproof paper (or No. Yi pumice) and water. Slush . off and dry. 10. Third coat of same varnish. Dry. FURNITURE FINISHING 325 11. Rub with FF pumice and water. Slush and dry. 12. Satin finish: Rub with rottenstone and oil. Slush and dry. Clean with naphtha. Alternate treatment: Rub with 30 steel wool. Wax if desired. Piano polish: Same, substituting water for rubbing oil. (A third or fourth coat of polishing varnish will speed the operation). When the surface is dry apply polishing oil. May be waxed instead of polished. Varnishing Precautions. Beware of dust, both from sanding and in the air. Never handle, sand or varnish any coating unless "thumbnail" dry. Always sand glossy surfaces to produce a "tooth" for anchoring the next coat. Use pumice and water to cut into the finish, rottenstone and oil to bring up the polish. Lacquer Finish. Because of its rapiddrying dustfree characteristic, and its hard, durable surface, the lacquer finish is a favorite where spraying equipment is available; some lacquers are manufactured which are suitable for skillful brushing. As previously stated, however, it presents a distinct fire hazard when spraying indoors. Not suitable for application over a varnish coat, which it "lifts," lacquer can be satisfactorily applied over shellac or shellac mixing lacquer. The fact that each coat of lacquer slightly dissolves the preceding lacquer film insures a perfect bond after a minimum of sanding to provide the necessary "tooth." When filler paste is used under lacquer, it should be cut with naphtha rather than turpentine, and care should be exercised that the pores are thoroughly packed to insure a level surface for the thinbodied lacquer. It is good practice to pad the filler with a handful of burlap, instead of relying upon the towingoff process alone to caulk the pores tightly.
