Overview

Rustins Knotting is a specialist solution designed to seal knots and resinous or creosoted timber, preventing unsightly staining or resin bleed-through on painted surfaces. Essential for preparing bare wood before painting, it creates a reliable barrier that helps maintain a flawless finish over time.

• Prevents resin and stain bleed-through
• Quick drying – ready to prime in 1 hour
• Requires 2 coats for creosoted/resinous timber
• Do not sand once applied
• Clean brushes with methylated spirits

Preparation

Ensure the wood surface is clean, bare, and sanded smooth before applying Knotting.

• Knotting is designed to prevent discolouration of paint, not to block excess resin.
• Remove any excess resin from knots using a heat gun prior to decoration.
• If there are cracks or holes around knots, fill them with Rustins Woodfiller, allow it to dry, and sand smooth before applying Knotting.

Proper preparation ensures that Knotting effectively seals knots and resinous timber, providing a smooth, even base for subsequent paint or primer.

Application

Always test a small area of the surface to be painted to ensure you are happy with the finished results.

• Using a brush, apply liberally over the knot and surrounding area to ensure full coverage.
• Apply 2 coats for resinous or creosoted timber to ensure complete sealing.
• Do not sand the knotting after application.
• Allow 1 hour between coats to ensure proper drying.
• Wait 1 hour after the final coat before applying primer or subsequent paint.
• Ideal: 15–25°C. Do not use below 10°C or in high humidity conditions

Following these steps ensures that knots and resinous timber are effectively sealed, preventing bleed-through and ensuring a smooth, even finish.
