HOW TO APPLY

PREPARE IT:
Any protruding nails should be dealt with; use a hammer and punch to knock them in. Sand off any blemishes and give the surface a good wipe over with a damp (not wet) cloth and allow to dry thoroughly. Stir the paint and apply it. If the boards are pitted or damaged, you may want to put some wood filler into offending holes, splits and gashes.

APPLY IT:
Depending on the condition of your floorboards, and the look you want to achieve, you may need two coats. If there are substantial blemishes then two coats are recommended, which will make them even harder wearing. Apply by brush or mini roller. Do not use a normal sized roller as this will cause drips in between the boards, which could be a problem if you are painting an upstairs room as the paint will work itself down onto the ceiling below. 
 
DRY IT:
It's usually touch dry in 12 hours, but please make sure it's completely hard before using the floor. Ideally leave it for two days (assuming the temperature of the room is 15°C and you have good ventilation), after which furniture should be 'placed' not 'dragged' over fresh paint to avoid scratching and damage.
