Maintenance, finishing and painting
Damages to steel sections can be fixed by degreasing and subsequent painting with RAL colour 9010. Avoid degreasing surfaces that will not be painted as a variation in gloss can occur.
Smaller damages and scratches to Gyptone tiles can be fixed by filling, sanding and touch-up paining with Gyptone repair paint.
For major damages, Gyptone tiles should be replaced. Alternatively, areas with large damages can be cut clean and filled with gypsum plaster from Gyproc A/S, after which the tiles can be plastered, sanded and painted.
Painted ceiling surfaces can be painted again without impairing the acoustic effect if on perforated tiles one avoids painting the backing tissue, plus avoids painting in the perforations.
It is therefore recommended that perforated tiles are painted with a short-pile mohair roller with a moderate amount of paint.
Perforated Gyptone tiles must not be spray painted as this significantly impairs sound absorption.
