Coo-Var Patent Knotting
This product is a high-performance, shellac-based solution formulated specifically for sealing knots and resinous areas in wood. Once applied, it prevents the resins from bleeding through paint films, ensuring a smooth and blemish-free finish. The translucent brown colour allows easy blending with wood grains, making it ideal for professional woodwork preparation.
Application and Uses
Designed for professional woodworkers and decorators, this product is easy to apply with a brush and can be used on all types of knotted and resinous wood. The formula is tailored to help prevent staining when applying paints or varnishes, making it perfect for interior and exterior wood surfaces. It is quick-drying, touch-dry in just 10 minutes, with a full hardness achieved after 2-3 days.
- Apply to new or prepared wood surfaces.
- For use on resinous or knotted areas of timber.
- Ensure proper surface preparation by cleaning and sanding before application.
Avoid using this product on metal, plastic, or non-wood surfaces, as it is specially formulated for wood sealing. Always ensure adequate ventilation during use, as the product contains a high VOC content. Refer to the data sheet for further details on application techniques and recommended preparation methods.
Drying and Recoating
The product is touch-dry within minutes and can be recoated after 6 hours at 20°C. Full curing and hardness are achieved within 2 to 3 days, ensuring a durable seal that will resist the effects of knot stains over time. For best results, ensure wood is thoroughly clean and sanded before application, and allow sufficient drying time between coats.

For best results, pair this product with an appropriate primer and topcoat.
