Additional information

A 100% dewaxed shellac based impregnating primer sealer. It is manufactured using a process that gives long-term stability and shelf-life. The absence of any wax in Sealcoat makes it compatible with all clear finish topcoats including solvent based polyurethanes. 

Recommended Uses
  • Doors, trim, skirting boards, panelling, wainscoting 
  • Cabinets, shelves, furniture, interior shutters 
  • Floors, stairs, banisters and spindles 
  • May be used to seal wood turnings, figurines, carvings, wicker, plaster, and other hobby/craft items. 

Sealer - May be used as an undercoat to prepare all new or previously finished interior wood surfaces for solvent based and water based varnish and lacquer topcoats. Can be sanded. 
Pre-Stain Sealer - When used as a pre-stain sealer and wood conditioner Sealcoat evens the porosity of woods such as pine and fir so stains penetrate evenly. Follow thinning instructions. Compatible with solvent based and water based wood stains. 
Barrier Coat - May be applied as a barrier coat to seal odours in certain types of wood and
particleboard. Not recommended for use as a sealer on exterior surfaces. 
Tinting - A wide variety of shades and tones can be achieved by tinting Sealcoat with Alcohol based stain, aniline dye, or small amounts of universal colourants- up to 15ml colourant per litre. Note that alcohol stains will dilute viscosity. If using powdered dyes, shake to completely disperse dye material and let container sit for a few minutes for bubbles to clear. 

Preparation
Surfaces must be clean, dry, and sound. Remove any wax from the surface with methylated spirits. Sand bare wood as smoothly as possible and remove all sanding dust. Previously applied wood stains must be completely dry. Previously applied finishes must be clean and tightly adhered. 

Application
Thinning is not normally necessary. Apply evenly and consistently and allow to dry 45 minutes before sanding with 120 or finer grit sandpaper. Remove all dust and apply finish coat. Note: A second coat of sealer will improve the film build and give added depth to the final finish on porous or open grain woods such as oak, mahogany, etc. Allow second coat to dry 1 hour before sanding lightly and applying finish coat. 
Brush application - For best results use a natural bristle brush. Apply a full brush load of Sealcoat to the surface using full, even strokes, brushing back into the wet material to maintain a wet edge. Do not over brush or brush back into material once it becomes tacky.
Wiping application - Use a lint free cloth. Pour or brush a liberal quantity of Sealcoat onto the surface and quickly work into the wood with brush, making sure sealer soaks thoroughly into any open or end grain. Wipe away any excess with cloth and stop wiping when surface becomes tacky. For vertical surfaces pour Sealcoat onto cloth and wipe over the wood. If the wood is stained, a second application may be needed to avoid sanding through the sealer and the stain. 
Spray application - May be spray applied using conventional, HVLP systems, or airless. Use a .011 to .013 tip and 800 — 1000 psi for airless spray application. Follow equipment manufacturer's instructions. 

Coverage Rate
Approximately 10-15m² per litre per coat. Spread rate may vary depending upon surface porosity and method of application. 

Directions For Use
Doors/Trim/Panelling/Cabinets/Furniture - Apply 1 or 2 coats by wiping, brush, or spray. Allow to dry completely before sanding with 220 or finer grit between coats to ensure a smooth finish. If a heavier film build is desired, repeat application. Remove dust and apply finish. 
Floors - Floors should be properly sanded and free of dust, dirt, or other contaminants. Use a brush or floor finish applicator and apply in the direction of the grain. Coat two or three board widths at a time, being sure to keep a wet edge. Avoid over applying or over brushing. Allow to dry for 45 minutes before sanding with 120 to 150 grit or finer sandpaper or screening. Apply second coat if desired. 
Pre-Stain Conditioner - Sealcoat is ideal for preventing uneven stain penetration over softwoods such as pine. Thin product by adding 3 parts methylated spirits to 2 parts Sealcoat. Apply with a brush or wipe on with a cloth, working with the grain. Do not over apply or recoat. After 15 minutes, lightly rub surface with fine synthetic abrasion pad. Apply stain according to manufacturer's directions. 
Odour Barrier Coat - Shellac based Sealcoat is an effective and dependable barrier coat for sealing odours in certain types of woods and particleboard. Two full coats are required for this application. 

Application Conditions
Warmer temperatures will accelerate and colder temperatures will prolong the drying time of this product. Do not apply when RN is greater than 85% or when temperature is within 2°C of the dew point. Sealcoat is not recommended for use in areas where surface heat exceeds 71°C. (Note — Brushing lacquers may soften sealer film during application. Do not over brush when applying lacquer or pulling may occur. Always test apply catalysed finishes over Sealcoat on scrap wood before using. 

Drying Time
At 20°C the first coat on bare wood will usually dry to the touch in a few minutes and can be sanded and recoated in about 20 to 30 minutes. Subsequent coats or coats applied over existing finishes will dry to the touch in 10 to 15 minutes and can be sanded and recoated in about an hour. 

Clean Up
Wipe up drips and spills with a rag soaked in methylated spirits. Clean brushes with methylated spirits. To dissolve product that has dried on application tools, soak tools overnight in methylated spirits. Clean sprayer equipment according to manufacturer's directions.
