Overview

Replace traditional window putty with Timbabuild Timbaglaze Multi-Purpose Glazing Sealant, a professional hybrid polymer glazing sealant designed for glazing, renovation and timber repair projects. Suitable for both interior and exterior use, Timbaglaze provides a durable, weatherproof and flexible seal that bonds to most common building materials, including damp and wet surfaces.

Developed as part of the Timbabuild Wood Repair System, Timbaglaze is the ideal choice for installing or repairing glazing units in timber windows, doors and frames. Unlike traditional putty, it offers exceptional initial grab, excellent UV and weather resistance, and can be painted after just one hour, helping you complete repairs more quickly.

Its permanently flexible, non-shrinking formula creates a long-lasting seal that absorbs movement without cracking, making it ideal for heritage restoration, listed buildings, renovation projects and everyday glazing repairs. Suitable for use with single and double-glazed units, including systems using butyl tapes and hot melt spacers.

• Although Timbaglaze can be applied to damp or wet surfaces, removing standing water will improve handling.
• Test adhesion on unfamiliar substrates before beginning large projects.
• Apply masking tape either side of the joint if a neat finish is required.

2. Trim the nozzle to the required bead size at approximately a 45° angle.
3. Insert the cartridge into a standard sealant or mastic gun.

6. Remove any masking tape before the sealant begins to cure.
