Service life – Up to 20 years when applied according to the methods outlined in BS6262 (1982) and BS8000: Part 7 (1990).

Coverage – For putty facing, coverage will be between 3 -5 meters depending on the rebate dimensions and frame type.

Drying time – Over paint when the skin has formed, between 7 – 28 days after glazing.

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

Priming:
All wooden frames must be sealed either an oil-based primer or with two (2) coats of Undercoat Primer prior to glazing.  Painted steel frames may be glazed without any further preparations. Galvanized frames must be treated with Galvanox Solution or allowed the weather naturally prior to glazing.  The suitability of the primer should be checked if hardened by wiping gently with white spirits.

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 pins (wooden rebates) or spring clips (metal rebates).  Apply putty to the front face of glass and smooth to a triangular fillet with a putty knife.

Over painting:
The product must be fully protected with an undercoat and topcoat after a surface skin has formed; i.e., after 7 days, but not later than 30 days after glazing.  Allow the undercoat to dry before applying the gloss.  Over painting, before the 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 stain should not be used as they do not afford adequate protection.

Maintenance:
Maintenance is essential for the long term performance of the putty.  Make good any defects/damages with fresh putty.  When painting/repainting, ensure the paint seal overlaps the joint between the putty and the glass and that the frame is well maintained.
