Hand Tools
Allow adequate time for the previous coats of joint cement to harden before applying a finishing coat.
1.Apply a thin finishing coat of Jointmaster wide enough to conceal the previously coated joint. Soften the outer edges of the newly trowelled compound with a damp brush before feathering the edges with a trowel.
2.Cover previously coated fastener heads, overlapping about 25mm.
Machine Tools
Apply a thin finishing coat of Jointmaster using a 250mm or 300mm finishing box.
Sanding
Allow compound to dry for at least 24 hours, then sand to a smooth finish using 180 grit sandpaper or 180-220 grit sanding mesh.
