CLEAR SEALER Simply better. • Excellent penetration into raw wood for inproved stability • Prevents excessive absorption of vehicle from undercoaters • Applies easily by brush or spray. GENERAL DESCRIPTION This is a phenolic resin-based sealer used for priming all types of raw wood prior to painting. The sealer acts as a moisture barrier layer to prevent peeling and excessive absorption of vehicle from undercoaters or varnishes by the new wood. It should be lightly sanded to a smooth surface before undercoating or varnishing. 2018 Clear Sealer can be used under all Pettit one-part undercoaters, varnishes and topside finishes. Do not use Clear Sealer on teak or other oily woods before varnishing or painting (use 2012 Super Dry Sealer). APPLICATION INFORMATION Stir 2018 Clear Sealer before application. 2018 Clear Sealer may be applied by brush, conventional or airless spray. Thinning is not normally required although on very warm days use Pettit 120 Brushing Thinner at 5-10% by volume to ease brushing and maintain good flow. When spraying, use Pettit 121 Spraying Thinner up to 20% by volume. Spray an even, wet coatto minimize orange peel. Do not apply 2018 Clear Sealer on extremely humid days or when rain is threatening. Do not apply in the late afternoon when working outdoors as the wet film may be adversely affected by dew. On fir or any wood that has a large hard grain pattern wipe with dry rags while the sealer is wet to remove the excess from the hard grain areas. 2018 Clear Sealer is not completely absorbed into the hard grain. SURFACE PREPARATION Wood must be clean, dry and properly prepared prior to varnishing or painting. When sanding wood, always sand with the grain. Use a vacuum, air hose, or tack rag to remove all traces of sanding residue. Follow all surface preparation steps carefully, avoiding shortcuts. Inadequate sur- face preparation will virtually assure inadequate performance.
