Description
What is 101 Multi-Purpose Linseed Oil Putty used for?
Linseed Oil Putty is a classic glazing compound used primarily for installing single glass panes into timber and metal window frames. Unlike modern silicone sealants, this 101 Multi-Purpose formula is designed to harden slowly over time, creating a robust, protective seal that moves naturally with the expansion and contraction of the wood. At ECO HEAT SHOP, we provide a professional-grade putty that is essential for maintaining the authentic look and structural integrity of period windows.
Why Choose Traditional Putty for Window Repairs?
The primary advantage of using a high-quality Linseed Oil Putty is its compatibility with organic materials. The natural oils penetrate the surface of the timber, helping to preserve the wood and prevent rot at the most vulnerable point—the glazing rebate. Our 101 formula is reinforced with high-grade fillers to ensure it doesn’t slump or crack, providing a superior finish that can be painted over once a protective skin has formed.
Professional Glazing and Maintenance Tips
For the best results, ensure that timber frames are properly primed with a spirit-based primer before applying the Glazing Putty. This prevents the wood from soaking up the linseed oil too quickly, which can cause the putty to become brittle. Once applied, the putty should be allowed to form a surface skin (usually 7–14 days depending on weather) before being painted with an oil-based gloss or undercoat. This ensures a completely watertight seal that protects your home from drafts and moisture ingress.
