How to Repair Sun-Faded Hardwood Floors

A floor that has undergone sun damage will fade in color because the wood has become too dry and lost its moisture. It's the actual heat from the sun that causes the damage. You repair floors by first determining if the boards must be replaced, or you can fix the problem by sanding and refinishing your floor. The other consideration is how widespread the damage is on your floor. Many times the sun damage is confined to a small area near a window.

Replacing Boards

Step 1

Drill holes along a damaged plank if only part of a sun-damaged board has to be removed and replaced.  Split the damaged section of the board with a chisel and hammer.

Pry out the damaged part with the chisel. 

Step 2

Pry out any complete planks that that you are going to replace with a chisel and hammer. 

Step 3

Measure and saw a piece of wood to replace an entire plank, or section of a plank, that is to be replaced. 

Step 4

Tap the board into place on the floor with a hammer. 

Step 5

Secure the board in the floor with nails. 

Step 6

Apply a coat of stain that matches the color of your floor. 

Step 7

Apply a protective coat of finish to the floor. 

Sanding and Refinishing

Step 1

Nail down any boards that are loose.  Hammer down any nails that are jutting out of the floor.

Fill in any grooves between the boards with a wood filler that has the same tint as the color of your floor. 

Step 2

Strip the finish off the floor with a varnish remover or sander. 

Step 3

Sand the floor several times, starting with a medium-grit sandpaper and finishing with a fine-grit sandpaper.  Continue sanding until the grain of the floor is clearly visible, and the wood feels smooth to the touch of your finger.

Sand in the direction of the wood's grain. 

Step 4

Sweep and vacuum up any dirt and debris from the sanding. 

Step 5

Stain and refinish your wood floor.
