Key Product Features: Ultimate performance primer-sealer Permanently blocks odours Unparalleled adhesion to any surface without sanding For interior and spot exterior use Seals knots and sap streaks Dried film is non-toxic and hypo-allergenic Shellac based Dries in just 15 minutes, recoatable in 45 minutes Coverage 12.5m² per litre Available with next day delivery While its primary strength lies in bonding to glossy or stubborn surfaces, the Zinsser BIN Shellac Primer also offers excellent stain-blocking properties for issues like smoke and water stains. For outdoor projects, it’s best suited for spot priming rather than general exterior use. Providing up to 12.5m2 per litre of coverage and touch dry within 15 minutes , the Zinsser BIN Primer is recoatable within 45 minutes and is available in two colours - white and grey - in various tin sizes including 500ml, 1L, 2.5L and 5L. Typically, one coat of Zinsser BIN Shellac Primer is sufficient to prime most surfaces effectively. However, for highly porous surfaces, an additional coat may be necessary to achieve full coverage and a properly sealed base. The number of coats required will depend on the surface being primed and the specific purpose of the application. Prefer water-based? Try the Zinsser BIN Aqua Primer.
