Ronseal Colron Knotting Solution

The Ronseal Colron Knotting Solution is a specialist wood preparation product designed to seal and stabilise resinous knots in timber before applying decorative finishes. This essential treatment prevents wood resins from bleeding through your final coating, ensuring a professional finish on interior woodwork projects. Ideal for use before applying varnish, wood stain, paint, wax or oil finishes, this knotting solution creates a barrier that stops knot resin from compromising your topcoat. The quick-drying formula is ready to overcoat in just one hour, minimising delays on joinery and carpentry projects. The 125ml bottle features a convenient in-cap brush applicator, allowing for precise, controlled application directly to problem knots without the need for separate brushes or cleaning equipment. This no-mess design is particularly useful for spot treatments on doors, skirting boards, window frames and other interior timber where knotting is visible.
