8.1 MATT FINISH
Surface Preparation:
Examine the plaster for cracks or marks. Fill
small hairline cracks with speckling material; fill
larger cracks with special patching plaster. Sand lightly
when dry for a smooth surface. Sandpaper over old gloss
or semi gloss paint to get good adhesion for the new
paint.
Clean the surface to remove dirt, oil, grease, rust
and flaking paint. Remove hardware from doors and windows
and loosen light fixture bases or cover these areas
with masking tape and scraps of paper or cloth.
a) Porous, absorbent, crumbly and sandy surfaces
must be primed with BIO Wall Primer. Let dry for 12-24
hours. New alkaline surfaces must be at least 6 weeks
old or use a special primer for alkaline surfaces.
b) Apply two coats of BIO Wall Paint. New Gyprock
surfaces need two or three coats initially.
