401-028 Chemseal Clear Vinyl Sealer

Chemseal is used for sealing wooden furniture and other wood surfaces for interior use only. It can be used on all wood types.

Wood must be sanded with a 120, 150 or 180 grit paper and free of dust and all contaminants. Stain systems under acid catalyzed coatings should be acid stable.

Apply 3-5 mils wet on sanded substrate. Allow one hour to dry at a minimum of 20ºC prior to topcoating. Sand with 280/320 grit paper before topcoating and ensure topcoat is applied within eight hours of sanding Chemseal.

Always mix Chemseal while adding catalyst and reducers in the recommended mixing ratios. Chemseal must be thoroughly agitated at all times to ensure product consistency. When catalyzed, avoid contact with metal surfaces.
