As the name suggests, crown molding is the crown jewel of interior decor. Depending on the style chosen, it has the capacity to subtly or majestically transform any space into one that oozes elegance and style.

Crown molding offers a smooth transition between the walls and the ceiling and adds to the overall cohesiveness of the space, bringing every other trim element together.

Because it is such a timeless aspect of the decor, it is natural that there are numerous commonly asked questions about its quality and installation. In this article, we will consider some of the most frequently asked crown molding questions.

1.   Does the size of the room and ceiling height affect the choice of crown molding?

The general consensus on crown molding installation is that the molding should be based on the size of the room and the ceiling height. The higher the ceiling height, the wider the molding ought to be.

If the molding is too thin on a tall space, it will create a disproportionate look. A very wide piece of crown molding, on the other hand, may make a small room appear even more shrunken.

However, there are arguments coming up to suggest that it is not the height that matters but how well the molding is picked out to suit the room. The key consideration is always how the crown molding will transform the whole space.

 As such, it is possible to install wide or built-up molding both in a large space such as the dining room as well as in a small room like the bathroom, as long as the overall finish is impeccable.

2.   How long does crown molding last?

Our molding is made from dense polyurethane that is moisture-resistant, does not accommodate the growth of mold and mildew, does not warp or crack, and is impervious to insect damage.

All these qualities come together to make the crown molding pieces long-lasting. The molding retains its luster throughout its life period and will require little maintenance.

3.   Can crown molding be used in any space?

A few decades ago, a major concern with crown molding installation was that the wood material was prone to rotting and accommodating mold especially in high-humidity spaces, posing a health hazard.

Material such as polyurethane overcomes this challenge as it is moisture-resistant. This means that now, crown molding can be used in any space including the kitchen, the bathroom, or the house exterior.

4.   Is crown molding easy to install?

Our polyurethane crown molding is light and flexible, making it easy to work with. Installation is easy even as a DIY project for a beginner with the right tools and minimal assistance. The tricky aspect lies in measuring and making the correct miter and coped cuts for the joints.

When putting the molding up, it is probably best to have an extra pair of hands to hold the trim up in position while you secure it to the wall. If you are not confident in your DIY skills, enlist the assistance of a handyman or an installation expert.

5.   What type of cuts should you make on the crown molding?

Bringing two pieces of crown molding together in a squared joint will not offer a firm fit because as the temperature changes, the two trim pieces will stretch out leaving unpleasant gaps. To overcome this, opt for mitered and coped joints instead.

Miter cuts will do well for outside corners while coped cuts will work for inside corners. To join two pieces of trim along the same length of a wall, used mitered cuts rather than a squared cut for a scarf joint. The equipment needed for these cuts is a miter saw (compound miter saw is best as it will be easier to make the correct angle cuts) and a coping saw.

6.   What causes gaps in joints?

Even where you have made miter cuts for a mitered joint, it is still possible to end up with gaps when the work is complete. This is simply an indication that the angle cut was not accurate.

A common mistake when making miter cuts is to assume that the wall corner is a perfect right angle and therefore the two trim pieces ought to come together in 45-degree cuts. In reality, most wall corners are hardly ever perfectly square. Instead, they will tend to be a few degrees off, intersecting at say 88-degrees.

To achieve a perfect fit, it is crucial that the wall angle is measured just right so the miter angle is equally accurate. A deviation of even 2 degrees is enough to leave the sore gaps every installer tries to avoid.

To help find the correct angle, test the degree fit with two spare pieces of trim and adjust slowly until you have found the right fit. Save this angle and use it on the actual molding. Test the fit again before fastening the molding to the wall permanently to be sure that it is as accurate as possible.

Even with all these precautions, however, sometimes a small gap will be inevitable. In this case, there is no need to panic and pull down the molding. Simply use a bit of caulk to cover it up and you’ll be good to go.
