Best Finish for Interior Wood Windows

There are a few different ways you can finish wood windows on the inside of your home. One way is to simply paint them. You can also stain them or use a natural finish.

Whichever route you choose, make sure you properly prep the surface first so that your finish will last.

If you’re looking for the best finish for interior wood windows, there are a few things to consider. First, what is the purpose of the finish? Are you looking for protection from the elements, or simply wanting to add a bit of color and beauty to your home?

Second, what type of wood are your windows made from? Different woods will take different finishes better than others. Finally, what is your budget?

Some finishes are more expensive than others. Once you’ve considered all of these factors, it’s time to decide on a finish. If you’re looking for protection from the elements, a clear sealer or varnish is your best bet.

These will protect the wood without changing its color too much. If you’re simply looking to add some color and beauty to your home, then paint is a good option. You can find exterior-grade paints that will stand up well to the elements if you’re worried about them fading over time.

Just be sure to prep the surface well before painting – sanding down any rough edges and priming first. If you have a limited budget, then stain is a good option for adding both color and protection to your wood windows. It’s important to choose a quality stain that won’t fade quickly in sunlight or peel off easily with age.

Once you’ve decided on the perfect finish for your interior wood windows, it’s time to get started!

How Do You Finish Interior Wood Windows?

Assuming you mean “trim” interior wood windows: Trimming interior wood windows is a pretty straightforward process, but there are a few things to keep in mind to ensure a clean, professional looking finish. Here are the basics:

1. Start by removing any existing trim molding or stops from the window. If there is old caulk or putty on the window, scrape it off with a putty knife before proceeding. 2. Measure the width and height of the opening and add 1/4″ to each measurement.

This will be the size of your new trim pieces. Cut these pieces out of MDF or another suitable material using a miter saw or hand saw. Sand the edges smooth if necessary.

3. Install the vertical sidepieces first, making sure they’re level and plumb (straight up and down). Use finishing nails or brad nails to attach them to the window frame, driving them into studs whenever possible for extra holding power. Then install the top piece and finally the bottom piece.

Again, use finishing nails driven into studs whenever possible for best results. 4.. Once all of your trim pieces are in place, caulk along all joints between trim and window frame using painter’s caulk or clear silicone sealant (if caulking isn’t your thing, wood filler can also be used in lieu of caulk).

Smooth out any excess with your finger then allow it to dry completely according to manufacturer’s directions – usually 24 hours is sufficient time for curing/drying time..
