If you live in a house with old floorboards, you are likely to understand the draught which can come from gaps in the floorboards. Filling these gaps is a good way to prevent draughts and stop your house getting cold in the winter. Learn the best ways to seal the gaps and stop those chilly draughts once and for all!
Prior to sanding the floor, cut strips of wood to plug the gaps, applying a wood glue to the insides of the boards. Tap the wooden strips into the gaps to great a tight seal. Continue this process for the whole floor until the gaps are all filled, then leave to dry completely.
Once the glue has dried, sand the floor and take off any high spots which might be left, due to any of the strips sticking above floorboard level. This will leave you with a smooth and gap-free floor. You can then go on to varnish or stain the floor to get a seamless finish.
It is possible to buy a special sealing agent which fills in the gap for you. These often come in a light tan colour and blend in well to the existing boards. As they remain a little flexible, they can move with the floor and can be applied to boards with no tongue or groove. The only drawback with this method is that the filler can wear over time and eventually fall through the gap.
