Natural Linseed Oil Putty

Natural Linseed Oil Putty is a multi-purpose putty that is specially formulated using only the best grade linseed oil, for glazing single glass into metal, softwood and hardwood window frames.

Benefits:

• Easier to apply than most competitive putties
• Extended shelf life
• For wood and metal frames
• Added plasticiser improves adhesion and helps prevent cracking

Areas for use:

• Single glazing of pretreated wooded and metal rebates.

Note: Unsuitable for plastic frames, heat absorbing glass, double glazing or frames treated with decorative microporous stains.

Surface Preparation:

• All surfaces must be clean, dry, free from dust, grease and other contamination.
• Priming: All timber frames must be sealed either with an oil based primer or with 2 coats of timber sealer prior to glazing. Painted steel frames may be glazed without any further preparation. Galvanised frames must be passivated or allowed to weather naturally prior to glazing. Check that suitable primers have hardened sufficiently by gently wiping with white spirits.

Application:

• Glazing: Work putty in hands before use. Ensure rebates are dirt free and prepared as detailed above. Apply putty to rebate, bed in glass and secure with non rusting pins (wooden rebates) or spring clips (metal frames). Apply putty to front face of glass and smooth to a triangular fillet with a putty knife.
• Over Painting: Product must be fully protected with an undercoat and top coat after a surface skin has formed, i.e. after seven, but no later than 30days after glazing. Allow undercoat to dry before applying gloss. Over painting before a skin has formed may result in bubbling and blistering of the paint film coupled with oil seepage. Over painting after 30days may result in cracking and a loss of adhesion. Varnish and preservative stains should not be used as they do not afford adequate protection.
• Maintenance: Maintenance is essential for long term performance of the putty. Make good any defects/damages with fresh putty. When painting/repainting, ensure the paint seal overlaps the join between the putty and the glass and that the frame is well maintained.
