Repairing Hardwood Floors
For people who have floor coverings on their hardwood floors but who are now wanting to restore the natural warmth and beauty of the original wood flooring, it will be necessary to strip the flooring down to the bare wood and remove the old floor sanding and finishing. Refinishing wood floors cannot be undertaken until the old finish has been completely and totally removed.
Floor refinishing is a pretty messy job, particularly during the sanding part, and it is important that you remove everything from the room before commencing, including the likes of curtains, furnishings, pictures and everything else. It is also vital that if you are attempting the job yourself, you should wear safety glasses and a safety mask in order to protect yourself by keeping particles of wood out of your eyes and the finish from entering your lungs.
Cooling and heating outlets all need to be sealed off with masking tape, and all doorways except the one you are using too. It is almost impossible to prevent a little bit of dust from sanding from entering the rest of the house, but by sealing duct outlets and doorways the mess should be reduced to an absolute minimum.
20-grit paper in the drum sander should be used for the first sanding. Be sure to go backwards and forwards over the whole floor along the grain, going slowly, and using either a sanding block or the disk sander in areas where the drum sander won’t reach. Repeat this with 40-grit paper, and then once more with 100-grit paper.
Vacuum thoroughly, and apply the new finish.
