431-22XX Selflac Pre-Cat Clear Topcoat

Selflac is intended for use on interior wood applications.

Substrate must be sanded using #120, 150 or 180 grit paper and be free of dust and all contaminants prior to staining or coating. Sealer must be sanded with a #280/320 paper before application of the topcoat and recovered within 8 hours after sanding. Eliminate all contact with metallic surfaces. Selflac must not be applied over metal, old oil finish or nitrocellulose lacquers. Stain systems used under Selflac should be acid stable.

Agitate material before use. Always mix Selflac to ensure products consistency and consistent gloss. Apply at 3 - 5 mils wet on sanded or sealed substrate. Selflac could be applied in 2 or 3 coats depending on desired finish. A thorough sanding of each coat with 280/320 grit stated paper is essential for proper adhesion. The subsequent coats must be applied the same day as the previous coat is sanded. Maximum film build of the system should not exceed 3 mils dry. Contact with metal sources should be avoided. Selflac must not be polluted with oil, varnish or the like and must not be sanded with steel wool between coats.

To obtain complete cure, Selflac should be applied at a temperature above 18°C and relative humidity below 65%. When drying, this product is not to be exposed to ammonia vapours. Finished surfaces must not be cleaned with ammonia containing products. Always use plastic or stainless equipment to eliminate discoloration due to oxidation.

Natural ambering or discoloring in the can may occur over time. Although there may be changes of color in the can as the product ages, this will have little to no effect on the product during application. Storing in locations above recommended room temperatures could accelerate ambering.

Selflac is used as a self-seal or with following sealers: 390-001, 390-0060, 431-1219, 546-8003 and 546-5192.
