Before Applying Polyvine Heavy Duty Floor Varnish
Ensure the surface to be coated is clean and free from grease, wax or polish.
White spirit or sugar soap should be used as cleaning agents.
Sugar soap should be rinsed off well with clean water and allowed to dry.
If water has been used on bare wood this would raise the grain.
The surface then needs to be sanded and vacuumed before coating Wooden floors should be sanded with an industrial sander to ensure a smooth finish.
Newly painted wood should first be sanded to provide a key.
H/D Floor Varnish should not be applied over uncured oil base paint as this may cause discoloration.
Older painted wood, where the paint itself may fail, should be stripped using a hot air gun or a chemical paint stripper, sanded and cleaned prior to coating.
When applied over emulsion/latex paint, it is possible that H/D Floor Varnish can draw certain stains through the paint which were not otherwise be visible.
In this case a stain sealer should be used.
