The Procedure To Fix The Hardwood From The Sun Damage:

Fixing your hardwood from damage by the sunlight is a very detailed process, so definite measures should be taken. Each step should be implemented carefully and precisely the way prescribed. 

Therefore, if you are not confident, I would suggest you seek professional help. If you are thinking of implementing it all on your own, then read the instructions attentively.

Things you need for refinishing the hardwood,

  • Fine- and medium-grit sandpaper
  • Sample board
  • Paint Brush
  • Wood Stain
  • Rags
  • Urethane Sealant
  • Vacuum Cleaner

Things you need for your protection,

  • Gloves
  • Dust Mask
  • Protective Eyewear

Here Are The Step by Step Guide to Fix Sun Damaged Hardwood Floor:

Step 1: Inspect the Hardwood floor

Before applying any product, I suggest you scrutinize the floor and identify the type of wood used in your hardwood floor.

It is crucial to find it out initially because Maple wood is extremely difficult to sand and stain, so I suggest calling a professional. 

No matter how big or small the affected area is, you should think about refinishing the whole room at once to equalize the hardwood floors’ color. 

Step 2: Prepare the Hardwood Floor

Once you have collected the required things and inspected the floor, now it’s time to prepare the sun-damaged wood floor. 

Empty the room; remove all the furniture and other kinds of stuff from the room. You can even use plastic wrap or so that it doesn’t get covered in dust. But I suggest you empty the space for productive results.

Sweep the floor thoroughly, don’t forget the corners and crevices.

Step 3: Time to use the Wood Filler

Now use the wood filler to fill in any deep gouges or very wide lengthwise gaps. It is wise to leave small gaps between the boards unfilled; sometimes, the wood expands and shrinks with the change of temperature & humidity. 

Step 4: Sanding down the Hardwood Floor

Then it would be best if you sanded down any scratches you see on the hardwood floor. But before that, you have to put on safety glasses, gloves, and a dust mask.

Don’t forget to close all the doors, windows, and vents to protect the dusk from blowing

Now use a 120 to medium-grit (depending on the stain level) sanding block to remove the stain entirely.

Step 5: Smoothing and Cleaning the Hardwood Floor

After sanding the wood, use sandpaper to smooth the area. 

Now use a vacuum cleaner to suck up all the dust; don’t forget to use the attachment to clean the dust from corners.

Step 6: Staining the Hardwood Floor

Now is the time for staining. But before you start staining, ventilate the room; open doors, windows, and air vents. This will reduce the strong fumes quickly out. 

Step 7: Painting the Hardwood Floor

Now let me tell you, getting the original color might be challenging; you can mix different shades to get the color you like. Mix the stain in a small container and apply a small portion at once.

With a clean rag, apply a small portion of the stain to the sun-damaged area, or you can start from one corner of the room. Let the paint dry overnight.

When the first coat dries out, lightly scuff the surface with fine sandpaper and apply another coat of urethane. I suggest you wait for at least 48-hours before putting back the furniture. 

Tada! You have your hardwood floors with a new appearance. 

Why Does Sunlight Damage My Hardwood Floor?

Direct sunlight can change the hardwood floor’s original color. The main reason for this is overexposure to three things; Ultraviolet Ray (UV Ray), Visible Light, and Infrared (IR) Light

Woods react to sunlight; that is, wood is highly photosensitive. Depending on the type of wood, the color changes after coming in contact with UV rays.

To illustrate, when tropical or exotic woods like Brazilian cherry contact sunlight and the color darkens. Then again, when it comes to domestic woods, like Maple or Red Oakwoods, the color usually fades out

Over an extended period of time, you will notice the hardwood floors with oil-based polyurethane finish turn in an orangey-yellowish color that you won’t like. 

Moreover, when UV ray and IR light combine with visible light, it steadily reacts with the wood and makes it darker or yellowish. 

Therefore, it becomes necessary to protect your hardwood floors from sunlight. 

How To Protect My Hardwood Floors From Sunlight?

Now you know how to repair your hardwood floors, but you also have to protect them from further damage. 

Let me mention four ways to protect your favorite hardwood floors,

1. Apply sun-resistant sealant on your floor

We all love the beautiful sunlight entering our rooms, don’t we? So, how to protect the hardwood floors?

Well, protect your floors by applying shellac, lacquer, varnish, polyurethane, or wax or oil finish directly using in your wood floors. 

Depending on your floor type, you should choose the product accordingly. If you are new to these things and don’t know how to use these on your hardwood floor, I suggest you seek professional help. 

2. Regularly rearrange your furniture.

The place that stays most exposed to the sun is more likely to get more damaged in that area. So what you can do, try swapping and rearranging the furniture to equalize the hardwood floors’ color. 

A large tree outside the window or putting a rug on the hardwood floor might reduce the damage. 

3. Use curtains or windows that prevent sun damage

The simplest way to prevent the sunlight from damaging your hardwood floors is to put thick curtains or blinds. Another way is to use room darkening window treatment. It will help to diffuse the UV ray but will not give the ultimate protection. 

You can also exchange your regular windows with laminated or Low-E coated glass. Manufacturers claim that it can hold up to 99 percent of harmful UV rays. You can also install a skylight to light up the room naturally. 

4. Install UV filtering window film

If you have your window already installed and don’t intend to change it in the near future, you can install a UV filtering window film.

This works more effectively to filter UV light and block infrared rays without hampering the transparency. It also helps regulate the temperature in your home.
