Finishing
PROMAFOUR®
PROMAFOUR® Joint Filler is applied to fill the screw heads.
1
Apply PROMAFOUR® Joint Filler to the screw
heads to make an even surface. Once filler has
dried you will need to sand it down for a
smooth surface.
The filler may contract overnight and require re-
applying and re-finishing the following day. This
should be done before decorating.
Apply PROMAFOUR® Primer and paint using
a suitable paint if painting.
Allow 24 hours for the fire place to
dry before painting.
TIP
Most other primers contain water, if you paint on to
this primer, the water content can turn to steam and the
paint can ‘blister’ - PROMAFOUR® Primer contains no
water - it is silica based and is ideal for this application.
