Site Applied Paint Finishes


The bare zinc of a hot dip galvanised finish needs a zinc chromate etch primer before further brush paint coats are applied. Oil based glazing putties and mastic sealants likewise need priming and sealing.

Take great care to keep flexible weatherseals and moving parts of fittings free of paint. Steel windows supplied galvanised only, without a factory applied polyester colour coating, have clearances set up between meeting surfaces sufficient for three or four coats of paint.

When the repainting programme has exceeded this, the paint build up starts to force the meeting surfaces apart and excessive force may be needed to close the window. This, in turn, can cause the window to bow or hinges distort.

If distortion has not gone too far, it may be sufficient to strip the paint of all meeting surfaces, taking particular care to clean off paint in the hinges.

If the gap is too great or the frame is badly bowed (tight at the centre and gapping at the corners), it may require off site refurbishment, please contact the office and request one of our surveyors to call.
