Why Do You Need an Expansion Gap?

The expansion gap is one of the most pivotal parts of any expansion joint. As well as insulate the building against environmental factors, excess noise, and other temperatures.

Essentially, this expansion gap allows the molding room to move a little bit so that it doesn’t crack because of changes in temperature and shrinkage.

If there wasn’t any expansion gap, the surface of the wood could be very susceptible to cracking. The molding manufacturer creates most expansion gaps, and the gap could be filled with putty and sanded.

But it’s easier to use a nail for setting up to put the nails through the molding and into the wall. Then you can use a putty knife and remove the excess putty.

How Much Expansion Gap Do You Need For Vinyl Plank Flooring?

The flooring will have to be secured to the floor joists in your home so that there will be a gap between the floor and the boards. This expansion gap is necessary to allow for proper ventilation.

Additionally, too large gaps can create moisture, causing mildew and mold to grow on the floorboard and the wood underneath it. Too small gaps can damage the floorboards.

If you are flooring new wood, you should keep the gap around 3/8″ to 1/2″. For older wood floors, you should keep your gap a bit larger, around 1/4″ to 1/2″.

In some instances, your flooring is very thick. You may need the gap around about 1/4″ to 1/2″ is a good range for most cases.

How Much Expansion Gap Do You Need For Concrete Floors?

As with wood flooring, there are different concrete depths, which can affect the expansion gap.

Therefore, before installing your concrete floor, it is essential to check the depth of your floor to ensure that your flooring is suitable for this type of installation.

When it comes to installing concrete flooring, the depth of your concrete floor will affect aspects such as aesthetics and soundproofing. For aesthetics, the higher depth of your concrete slabs would be best, and it always looks better!

As well as, thicker slabs have more volume and make for a roomier appearance. While for soundproofing purposes, a 12mm expansion gap is recommended.

You can also install a 5mm expansion gap if your slab is less than 12mm in depth. But keep in mind the thicker slabs will offer more noise insulation leading to an overall quieter home environment.

A floating floor is a type of flooring that can be applied to any part of your house. You can install them in kitchen and dining rooms, as well as bathrooms.

A floating floor can be used for various reasons, but it is best used for remodeling an older home, and it is easy to install and looks good in most homes.

Additionally, it is essential to know how much expansion gap you need. The expansion gap is measured by the number of inches, one way or the other, of space the floorboards will require to expand in the dry, unheated season.

By installing the flooring with this space and leaving it open, the boards can expand without causing buckling and damage. Because of this, it is essential to ensure that the expansion gap is done correctly.

When laying flooring, you should leave about a 10-12mm expansion gap around the perimeter of each board.

This is to allow for movement as the temperature fluctuates. If the space is too small, the boards can warp, bend and crack as a result.

Steps To Filling The Expansion Gap

  1. Firstly, don’t let water sit in the expansion gap of your new vinyl flooring. Then apply a thin layer of flooring adhesive to the top of the subfloor.
  2. Now place a sheet of underlayment in the expansion gap and roll out your flooring in the room.
  3. Apply a layer of adhesive to the back of your flooring at the expansion gap and apply a thin layer of flooring adhesive to the top of the underlayment.
  4. At the moment, you have to place your flooring down into the expansion gap, press the flooring down into the adhesive, then remove the excess adhesive with a squeegee.
  5. Now you can fill the expansion gap with a thin layer of flooring adhesive. And wipe up the excess adhesive with a rag. Lastly, leave the room closed for at least 24 hours.

Frequently ask questions

Can you install vinyl plank flooring on an uneven floor?

What kinds of rugs are safe for vinyl plank flooring?

You can look at rugs with a natural backing, such as cotton or jute. As is the case for all vinyl floors, rubber and latex mats might cause staining/discoloration, but there are some top-quality options out there that should be safe to use on your floor.
