Application steps

SUBSTRATE PREPARATION

All surfaces must be clean, dry and free from dust, grease and other contamination.

PRIMING
All timber frames must be sealed either with an oil based primer or with two 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 (calcium plumbate, zinc chromate) have hardened sufficiently by gently wiping with white spirits.

APPLICATION

GLAZING
Work putty in gloved 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.

OVERPAINTING
Product must be fully protected with an undercoat and topcoat after a surface skin has formed; i.e. after seven, but no later than 30, days after glazing. Allow undercoat to dry before applying gloss. Overpainting before a skin has formed may result in bubbling and blistering of the paint film coupled with oil seepage. Overpainting after 30 days may result in cracking and a loss of adhesion. Varnish and preservative (microporous) 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.
