Using a broadknife or trowel, apply a thin top coat of Topping Compound wide enough to conceal the previously coated joint – about 250mm. Soften the outer edges of the newly trowelled compound with a damp brush before feathering the edges with a trowel.
Cover previously coated fastener heads, overlapping about 25mm.
Sanding
Allow compound to dry and harden for at least 24 hours, then sand to a smooth finish using 150 grit sandpaper or 150-220 grit mesh.
Painting
Apply all paints in accordance with paint manufacturers recommendations
NOTE: In wet area applications, a topping coat should not be used on areas to be tiled
