The UltraSeal WB Sealer and Barrier Coat (USH3000) is a water-based dewaxed shellac finish designed to function as a sealer and barrier coating. This product is made from high end shellac, dissolved in water through the unique EmTech system.

UltraSeal WB can be used on any interior wood surfaces that requires undercoat conditioning, pre-stain sealing or sanding sealer applications. The Ultraseal WB Sealer and Barrier Coat features excellent adhesive property when used as a tie-coat between oil based stains, glazes and topcoats.

Ultraseal WB can be tinted using water-soluble aniline dyes and universal pigments.

The unique properties of the dewaxed shellac resin within UltraSeal WB will produce a depth-of-image and color tone generation identical to alcohol-cut shellac.

UltraSeal WB can be retarded with Target SA5 Retarder to help slow the wet-edge set time for better control when brushing large areas.

Directions for use

Preparation:

As a Pre-Stain conditioner:

Surface needs to be clean, dry and free of any contamination. Sand the surface using a 220 grit or finer sandpaper. Dilute Ultraseal WB with 25 % by liquid volume of water. This will allow a better penetration and easier control on the absorption of the color.

As a Sanding Sealer:

Use UltraSeal WB undiluted to act as a traditional shellac sanding sealer on all types of domestic and exotic wood species. Sand wood substrate with 220 or 320-grit sandpaper.

As a Barrier / Bond Coating:

UltraSeal-WB™ acts as a thin film forming barrier/bonding coat to improve adhesion and film formation qualities over contaminated surfaces.

Application:

As a Pre-Stain conditioner:

Apply 1 coat of reduced conditioner. Allow to dry for 45 minutes to 1 hour before fine sanding and evaluating for color coat application.

As a Sanding Sealer:

Apply 1 coat of undiluted UltraSeal-WB via brush, spray or wipe application (see Application Methods). The first coat of UltraSeal-WB will penetrate and dry to the touch within 15-20 minutes. Allow to dry for 45 minutes to 1 hour before fine sanding and evaluating for color coat application.

As a Barrier / Bond Coating:

Apply a wet film thickness of 1-2 mils and allow to dry for a minimum of 1 hour before evaluating for second coat. Sand first coat with 600-grit sandpaper and remove dust with water dampened lint-free cloth. Apply second coat and evaluate when dry.
