History of Picture Frame Moulding

The use of picture frame moulding, also known as box moulding, dates back to the18th century in Europe, it became popular for framing paintings and mirrors in grand homes and palaces.

Today, picture frame moulding is commonly used on walls to add dimension and visual interest.

It can be used to frame family photos, artwork, mirrors, or even architectural features like doorways and windows.

When choosing a picture frame moulding for your home, consider the style of your space and choose a design that complements it.

Thin, sleek mouldings work well in modern spaces while ornate mouldings can add a touch of elegance to traditional or classical interiors.

And while this moulding looks high-end, it doesn’t require tons of skill to pull it off.

Installing picture frame moulding is relatively easy and can be done as a simple DIY project.

Either way, adding picture frame moulding is a simple and affordable way to elevate the look of any room in your home.

The Basic Materials and Tools Needed

Because we used the prefab corners on our walls, we did not need to make any miter cuts.

However the same method and technique would work even if you chose to miter your own corners.

Here’s a list of supplies and tools we used:

Measure and Plan design

Before starting your picture frame moulding project, it’s important to measure and plan the design layout.

First, determine where you want to add the moulding and what you will be framing (photos, artwork, etc.).

Then, measure the dimensions of these pieces and mark them on the wall with a pencil.

In my case, I wanted one box moulding piece to be directly centered over the desk.

This is where I want to hang a large piece of art.

Then I planned for 2 smaller boxes on each side.

In these boxes I will install sconces.

Graph paper with design of decorative wall moulding

I first made a plan on graph paper, then take these measurements to the wall.

Take into account windows, doorways as you map out your plan. You’ll want to also take into consideration outlets and light switches.

To get a good visual of what the design will look like, we made our horizontal and vertical lines with a pencil and a chalkline.

Then we placed painters tape along these lines, checking with a level to make sure everything is perfect.

By doing this, we can stand back and look to see if the design feels balanced in the room.

Also by placing the painters tape on the wall we found that we needed to adjust our design in a few places to avoid electrical outlets.

Certainly it’s so much easier to figure out these technical difficulties before you start cutting and installing the moulding.

Taking the extra time to use a level will result in clean and professional looking picture frames.

In addition, the painters tape is aligned where we’ll install each picture frame moulding piece to make installation much faster.

Calculate How Much Moulding You’ll Need

Once I had the plan on graph paper, I could easily figure how many corners and how many feet of picture frame moulding I needed.

Just a little side note, Ornamental decorative millwork also sells rectangular picture frame moulding pieces that you simply attach to the wall.

It would be perfect for a wainscoting application and super easy to do!

Paint Wall First

Over the years we installed several accent walls, and have found it easier to paint the wall first.

Then once the moulding is installed, you just need to brush the moulding with paint.

Trust me, it’s a lot easier to paint your wall before installing your accent moulding.

Attach Corner Pieces

Begin by attaching the four corner pieces to your first box.

We applied a small about of construction adhesive and aligned it with the tape.

Green painters tape holds the corner piece of the picture frame moulding.

Then we placed a couple of pieces of painters tape to hold it into position while the adhesive dried.

Measure and Attach Picture Frame Moulding

Once all of the 4 corners are installed, measure the distance between each of the corners and cut the picture frame moulding to fit.

Then we applied a little construction adhesive to the back of the picture frame moulding and placed it into position.

Again we used painters tape to hold it in place while the adhesive dries.

Tips for Installing Picture Frame Moulding

When installing picture frame moulding, it’s easy to make the mistake of using the ceiling or floor as a guide for determining what is level.

However, these surfaces may not actually be level themselves and can result in wonky frames.

Instead, use a level tool to ensure each piece of moulding is properly aligned.

Start by attaching the top piece of moulding first, using a level to make sure it is straight.

Then, continue installing the other pieces, using the top piece as a guide for ensuring they are also straight.

Also I’d recommend using a longer level like a 4 ft. level.

It will help ensure that each piece is aligned properly.

A laser level isn’t necessary here, but it will definitely makes this process easier!

Always measure 2 or even 3 times and cut once.

I’ve been know to make a wrong cut a time or two.

Take the time to map out your design with painters tape.

By doing this you may find you’ll need to make adjustments for outlets.

Complete one entire box frame before moving to the next.

This way the adhesive is still wet if you need to make any adjustments.

You may need to place a few brads in your moulding if your wall are bowed.

That was the case on our largest box.

We knew the wall bowed, but we thought the tape would hold it in position as the adhevive dried.

But when we removed the tape we noticed it was loose in a couple of places.

It was a quick and easy fix.

We simply squirted a little construction adhesive in the gap and shot in a couple of brads.

Caulk, Putty, Paint

The last step to beautiful box paneled walls is to caulk, putty and paint.

And that’s a job in it’s self.

Be sure to check back next week as we caulk, putty and paint.

You are going to want to see Steph’s caulking technique!

It’s a game changer!

Plus we’ll share tips on when to use caulk, wood filler, wood putty and spackle.
