Once the primer is dry, lightly sand the floor with a fine-grit sandpaper to remove any bumps or imperfections. Then, vacuum and wipe the floor again as before. Stir the tin of varnish thoroughly and pour some into a container. Repeat the same process as with the primer, using a microfibre roller and a brush to apply a thin and even coat of varnish on the floor. Start from one corner of the room and work your way towards the door. Follow the direction of the wood grain and avoid overlapping or leaving gaps. Varnish provides durability and gloss to the floor. You can choose from different gloss levels depending on your preference. Let the varnish dry completely according to the manufacturer’s instructions.
