Pine floors can instantly transform your home, giving a rustic quality to your home. The knots and golden tones inherent in the pine add a sense of texture to your rooms. If your pine floors are in an older cottage or house, you'll need to restore the pine floors before you sand and finish them. You'll need to work with care as pine floors are softer than oak. While this is a slightly longer process, it will ensure that you restore your pine floors to their former glory.
Vacuum the floors to remove any stray dust or debris. Combine 1/4 cup vinegar with 887ml of water in a spray bottle. Spray the floors thoroughly and wipe up the moisture with a soft cloth. Continue spraying the floor until you've sprayed the entire surface area.
Sand the floors with an electric sander with 150-grit sandpaper installed. Repeat with a sheet of 180-grit sandpaper installed in the bottom of the sander. Examine your floors carefully. Fill in any cracks with wood putty and sand smooth. Vacuum up the dust from sanding.
Pour a wood oil into a pan and dip a clean paint roller into the oil. Apply a thin, even coat of oil to the floors, until you cover the entire surface area. Allow the oil to soak for 12 hours, giving moisture back to brittle or old pine floors. As the oil is soaking, rinse off your paint roller and pan.
Pour a tinted or untinted polyurethane finish into a paint roller pan. Dip your paint roller in the pan and apply a thin layer of finish to the pine floors. Allow the finish to dry for around 12 hours and then sand with 180-grit sandpaper. Vacuum up the dust from sanding.
Apply a second coat to the floors and allow it to dry for a full 12 hours. Sand the floors with your electric sander and vacuum carefully. Apply a final coat of finish and allow it to dry another 12 hours.
