How to refinish hardwood floors:

First things first: preparation

Before refinishing hardwood floors can begin, it’s necessary to take care of any repair work or replacements, as well as cleaning thoroughly so the new finish will have a clean surface for bonding. Sanding down the flooring is also necessary in order to remove previous scratches and water spots.***

In order to refinish your hardwood floors, you must first remove the old finish using a sander. These sanders are not for a novice, they are bulky and difficult to operate.

If you leave the too long on one spot you will sand to much creating valleys or ripples. This will not be easy to see UNTILL you apply the poly. Then it will be too late and horrible. You will also need to use a edge sander to get next to the wall as close as possible, blending in the two sanded surfaces. ( this step is very important and difficult)


Then, you’ll need to clean up all dust with a damp cloth and wipe dry. Doo not spill anything on your sanded surface including water. The entire sanding process will need to be redone. Liquids raise the grain on hardwood and the only way to remove is re-sand, You can not spot sand!!

Now apply stain evenly over the floor using a brush or roller then allow it to dry for at least 24 hours. Minwax stain is one of the best but there are others that will work.

Apply polyurethane sealer on top of the stain. EVENLY!!!

Once applied correctly, allow each layer of polyurethane sealer to dry for at least 12 hours before applying more coats. In different temperatures the dry ray rate will be different.

Finally, apply four coats of poly to the surface allowing each coat 12 hours to dry depending on the temperature. lightly sanding between coats.
