Bed Molding 101: An Engineer'S Guide

You know as an engineering student or engineer that a well-designed space is about more than just how it looks.

Bed molding comes into play here.

If you don't know about it yet, you're missing out on an important part that can make any room look and feel better.

Bed molding can be the missing piece that brings everything together.

It can add to the architectural style of a room and make it feel more sophisticated.

In this article, I'll get into the world of bed molding and talk about its purpose, different types, how to install it, and design considerations.

This article is a must-read for any engineering fan who wants to take their design skills to the next level.

It doesn't matter if you're designing a room from scratch or want to update one you already have.

Introduction to Bed Molding

Formal definition:

1. The lowest member of a band of moldings 2. Any molding under an aprojection, such as between eaves and sidewalls.

Bed molding, also called bed moulding, is a narrow trim that is often used in interior design to cover the gap between a wall and a ceiling.

It's usually under the cornice, and it adds a decorative touch to the inside or outside of a house while hiding the joints at the corners.

This article will talk about the different kinds of bed moldings, how they differ from crown molding, and things to think about when choosing interior moldings for a home.

Factors to Consider When Choosing Interior Moldings

Moldings and trim can be used on the floors, doors, windows, and ceilings of a home, among other places.

When picking interior moldings for a home, it's important to think about style, budget, type of material (e.g., wood or MDF), size of the room (e.g., ceiling height), and installation location (e.g., centralized rooms).

Revolutionize Your Home Decor: Discover the Power of Bed Molding

Still hard to understand? Let me change the point of view a bit:

Are you sick of people telling you to "reach for the stars" and "aim high" when it comes to decorating your home? Well, I have some advice that will change your life: aim low.

In particular, you should aim for the bottom molding, which is also called "bed molding.

Yes, you should get rid of all those fancy crown moldings and ceiling medallions.

It's all about bed molding.

Still not sure? Let's learn more about bed molding and why this often-overlooked detail could be the key to a well-designed room.

Okay, that was just a joke made to look like a TV ad.

Now let's go back to the explanation.

Types and Characteristics of Bed Molding

Bed moldings fit into corners better than crown moldings but less well than cove moldings because they are deeper.

Types of Moldings

There are many different kinds of moldings that are used to decorate homes today, and each one serves a different purpose.

Some common kinds of moldings are:

  • Moldings for decorating.
  • Molding for Casing or Architraves.
  • Baseboards and Styles of Baseboards.
  • Crown Moulding.
  • Molding for a chair rail.
  • Molding for the picture rail.
  • Molding of a bead or pearl.

Crown molding is one of the most common types of bed moldings.

It connects walls and ceilings and is usually very fancy, with substyles like dentil or egg-and-dart.

Design Considerations for Using Bed Moldings in a Room

When putting bed molding in a room, there are a few things to think about in terms of design.

The color of the molding is an important thing to think about.

Putting a bold color of paint right on the molding can make it stand out and bring life to a room.

The molding can also give a bold color a natural place to end, making the look much more comfortable than if the whole wall were painted.

Another thing to think about is making sure that built-up moldings don't hit other things in the room, like fans or showerheads.

When designing and installing built-up moldings, it's important to keep in mind that the lengths change as layers are added.

When you use bed molding in a room, you should also think about the baseboards.

There are three ways to deal with baseboards: remove them, leave them and cut a base notch, or install the Murphy bed flush with the wall over the existing baseboard without cutting into or removing it.

Lastly, picture frame wall molding is a simple way to make a room look classier and more elegant.

These squares can be made of wood or polyurethane and painted a different color than the wall for contrast or the same color as the wall to add texture and depth to a space.

Bed Molding vs Crown Molding

Bed molding and crown molding are both types of trim that are used to cover the gap between the wall and ceiling.

The main difference between crown molding and bed molding is that bed molding fits into corners better and has less of a shadow line.

Crown molding sticks out more from the wall, while bed molding, which is an extension of a cornice mold, can be flush with the wall.

Bed mold is like a piece of crown that was broken in half.

Materials and Installation of Bed Molding

Crown molding can be made of plaster, polyurethane, or medium-density fiberboard, among other things (MDF).

Materials Used for Bed Molding

When it comes to cutting and fastening, the installation process is affected by the choice of material.

Here are some common bed molding materials and some things to keep in mind when installing them:

Plastic crown molding is usually more expensive than other materials, and because it is so heavy, it needs special tools to be cut and put in place.

Polyurethane crown molding is a durable material that is even stronger than wood and resistant to mold and rot.

It can be cut with standard woodworking tools like saws and routers, and it can be glued or nailed into place.

MDF crown molding is a cheap option that looks like wood but costs only a fraction of what it would to buy real wood.

It can be cut with common woodworking tools, but it may need more sanding before it can be stained or painted.

It can also be put in place with glue or nails.

Installation Process for Bed Molding

You will need some basic carpentry tools, like a saw, nail gun, and caulk, to install bed molding.

Here's what you need to do to install bed molding:

  • Cut the molding into the right size pieces.
  • Find and mark studs, as it's best to nail molding into a support structure.
  • Glue the parts of the molding that will touch the wall or ceiling before nailing it in place.
  • Use paintable caulk to fill in any gaps between the corners of the bed molding and the wall or ceiling.

Put a small line of caulk on the crack and smooth it out with a damp cloth.

Do this again for any nail holes that you can see.

Bed molding can also be put up with the help of a protractor.

It can help you get accurate measurements for cutting angles on the corners where two pieces of molding meet.

It's best to use a 16-inch long protractor because builders' corner caps make drywall thicker and can throw off your reading.

Removing or Replacing Bed Molding

Bed molding can be taken off or put back on in two ways: with clips or with glue.

But the way to take off or put on bed molding can be different depending on the type of molding and how it is being used.

For general information on how to remove and replace bed molding, you should talk to a professional or look at the manufacturer's instructions for the type of bed molding you are using.

Bed molding is a type of crown molding that is put up where the ceiling meets the wall.

It can be made of different materials and installed in different ways, depending on the material.

Installing bed molding requires basic carpentry skills and tools.

The best way to remove or replace bed molding depends on what kind of molding it is and how it is being used.

Costs and Conclusion of Bed Molding

Here are some things that can change how much bed molding costs:

  • Type of molding: There are different kinds of bed molding, and each has its own price.

Crown molding, cove molding, and picture frame wall molding are all popular types of bed molding.

  • Material: The cost of bed molding can depend a lot on what kind of material is used to make it.

Plaster, polyurethane, and MDF are all common materials for bed molding.

  • Complexity of the design: The more complicated the design, the more time and effort it will take to install, which can raise the total cost.

Estimating the Cost of Bed Molding

The average cost of installing trim in a house across the country is $1,331, but it can cost anywhere from $606 to $2,089.

But it's important to keep in mind that this is a general estimate that doesn't apply to bed molding.

If you hire a professional carpenter to install bed molding, the cost can range from $65 to $100 per hour, depending on the hourly rate.

In addition to the cost of labor, you will also need to consider the cost of the bed molding material itself.

For example, an eight-foot length of wood crown molding usually costs around $32.

Before putting in new bed molding, removing the old ones can cost between $0.55 and $1.17 per linear foot.

In conclusion, the total average cost per linear foot for installing bed molding ranges from $4.05 to $9.86, depending on the type and material used.

But it's important to remember that these are just estimates.

The real costs will depend on the size of the job, the conditions, and the options you choose.

Overall, bed molding can add visual interest and value to your home, and the cost of installation will depend on a number of factors.

To get a more accurate estimate for the bed molding installation project, it is best to talk to a professional.
