Pure Shellac for Ultimate Performance

A one coat high performance shellac sealer primer to:

  • permanently kill stains and odours

  • seal knots

  • cover damage from water, smoke and mould

Blockade White Shellac Sealer Primer provides excellent adhesion to almost all interior surfaces such as previously coated and new wood, plaster, drywall, porous wallcoverings, metal and tile and requires minimal preparation before use.

Blockade is quick drying, saving time on jobs that require multiple coats or to be quickly overcoated with emulsion. The pure shellac base permanently blocks stains and odours, covering even the darkest of colours.

  • Permanently kill stains and odours

  • Does NOT raise the grain of wood unlike waterbased primers.

  • Seal knots and resin in 1 coat on new wood.

  • Covers damage from water, smoke and mould

  • Blocks out stains from nicotine, mould, smoke/fire, water and more

  • Seals in tannins and wood knots, grease and porous surfaces including new plaster

  • Blocks odours including cigarette smoke, other smoke smells and damp

  • Effortlessly covers dark paint colours, lipstick and crayon marks, rust and ink

FAST DRYING

Touch dry in 15 minutes. Recoat after 45 minutes, if required. Allow 45 minutes before overcoating with paint.

White Shellac Sealer Primer

Ideal for use on all interior woodwork and plaster where a rapid matt finish is required. Covers glossy and hard to paint surfaces such as tile, varnish or gloss paints with no sanding needed. The pure shellac base permanently blocks odours including nicotine, smoke and mould. Use as a sealer and primer over even the darkest paint colours prior to overcoating with emulsion.  Seals in stains from grease, water, smoke, crayon, ink, lipstick, rust and wood knotting in just one coat. Can be used to seal porous surfaces so topcoat paints have better coverage. Can be used as a base for both water-based and oil-based paints.
