Coo-Var Shellac Prime-All is a white heavy duty shellac based coating. It is designed to be applied to difficult stains and odours such as nicotine, pen, oil and water. This prevents them from bleeding through subsequent coats.
It is ideal for use to seal tar, creosoted and bitumen surfaces and can be used as a spot primer for exterior surfaces. It has fast drying properties and can be overcoated with both oil and water based paints.
Touch dry in 10 minutes and hard dry in 30 minutes. Leave 30 minutes before overcoating.
Estimated Coverage: 10sqm per litre
