How to refinish oak flooring.
Filed Under Oak Flooring | Leave a Comment
Oak flooring is extremely durable and easy to maintain. But with continuous use, even a well-cared for oak floor will start to show some wear. One of the best things about wood flooring is that it can be refinished. So unlike carpeting or tile, which must be replaced once it starts looking tired, wood floors can easily be brought back to life again.
How do you know when it’s time to refinish your oak flooring? The finish will start to lose its luster and you’ll see lots of superficial scratches on the surface. The next step is figuring out what kind of finish your floor has now. Because you’ll need to use the same kind when you refinish your oak floors.
Can I refinish my wood floors myself?
Refinishing hardwoods floor isn’t hard. But it is messy because it produces a lot of sawdust. And if you use an oil-based polyurethane, the fumes can be pretty noxious. So if you have respiratory problems, it’s probably best to hire professionals to refinish your floors.
Professionals usually charge between $1.50 and $3.00 per square foot. That price should include materials.
If you do tackle it yourself, you’ll need to rent a sander or two, buy sandpaper, miscellaneous supplies like tack cloth, and whatever stain or finishes you choose.
No special skills are required. But you will need to take care in order to get results that you’ll be happy with for years to come.
Sanding your oak flooring.
First, empty the room, removing all furniture, carpets, window treatments, etc. Remove the nails from any baseboards or quarter round, and take them off. To make them easier to reinstall, number them and put the corresponding number on the wall.
Go over the wood flooring and remove or countersink any nails, carpet tacks or staples. These can tear the paper you use to sand the floors – which is annoying, because you have to stop work, and expensive, because it wastes sandpaper.
Once your room is prepared, your next stop is the equipment rental store. There are several types of sanders you can rent. A drum sander is the choice of professionals, but they can be hard to control. And if you don’t keep them moving they can sand down one spot so quickly that it will leave a dip in your floor. Or worse, remove the entire veneer.
An orbital sander is easier for beginners to manage. Have the person you rent the sander from demostrate it for you and make sure you’re comfortable with it before you leave the shop. Most big sanders won’t reach all the way to the edge of the floor, so rent an edging machine or a palm sander for the hard-to-reach spots.
You’ll need several grades of sandpaper, usually 36-, 60-, 80-, 100-, and 120-. Start with the coarsest (36). Run the sander back and forth with the grain in smooth, even strokes. Always keep the sander moving when it’s turned on. Otherwise, you may sand one area too deeply. And be sure to use a respirator every time you sand.
When you finish sanding your wood floor, vacuum up all the sawdust with a shop vac, and go over the floor with a tack cloth to make sure all the dust has been removed. Then, repeat the process with every grade of sandpaper. By the time you get down to the 120-grade, your oak floor should be soft as a baby’s bottom.
Use the edger or palm sander to prepare the parts your couldn’t reach with the bigger sander. Then, clean the floor as thoroughly as you can, removing any remaining dust. The cleaner you get the wood, the better the finish will be.
Finishing your oak floors.
If you want a shade that’s darker than the natural color of your wood flooring, you’ll need to apply a stain. For subtle changes, apply the stain with a rag. For a more dramatic difference, use a brush and remove the excess with rags. Do a test in the back of a closet or some other inconspicuous place to make sure you like the color.
Let the stain dry completely. Then apply a second coat if you want more color.
Otherwise, you can start applying the polyurethane finish. There are two main types of polyurethane used for finishing hardwood floors: oil-based polyurethane and water-based polyurethane.
Oil-based is a little easier to work with because it takes longer to dry, so it’s easier to blend and go over any mistakes. It yellows a little with age. The downside is that the fumes can be quite strong. Water-based product dries very quickly, which can sometimes result in streaks where wet polyurethane was applied over partially dried finish.
Stir the polyurethane well, don’t shake it – that can cause bubbles that will end up in the finish. Then apply it evenly with a brush or roller. Go with the grain, working as quickly as you can.
When the first coat has dried thoroughly, sand lightly with the finest grade of sandpaper and then apply another coat. Wait at least three days before reattaching the baseboards and moving furniture and rugs back into the room. Then, sit back and enjoy the renewed beauty of your wood flooring.
