Age of the Concrete

If your concrete slabs are new, you should let them cure. This means you let the concrete settle in for at least 30 days. You should check it for both dryness, and how leveled it is.

The next step is to tackle cleanliness. Ensure that there is no dust or debris or infestation of mold or fungi that may have taken place.

Also, make sure that there is no permanent water damage that cracks or bends the concrete flooring. The surface should ideally be smooth. Try using a long level that can allow you to know if the floor is in the right condition.

If there is a variance of 3/16th of an inch every 10 feet, then you need to level it! You can do that with a grinder as well.

Choosing an Underlayment for Concrete flooring

Concrete flooring poses a lot of problems since it a porous material. Its moisture levels always tend to fluctuate, and this can damage the glue and adhesive-based laminate flooring.

This is why it is all the more important to have an underlayment that can fight off moisture and make up for cracks and bumps that would otherwise lead to uneven flooring.

You do not want your laminates to warp under, so here are some options you should consider when it comes to the right underlayment.

  • Foam Barrier: The most common underlayment is a foam barrier, which can be a good option for moisture. It also absorbs any noise and seals the flooring through and through.
  • Cork: Cork, while is expensive, is a great option for reducing noise and cracking when you walk on the flooring.
  • Vinyl Backed: Vinyl-backed underlayments are recommended not only to reduce noise but are also suitable for moisture control.

Is it Necessary to Place the Moisture Barrier?

Moisture is the enemy of laminate flooring! You need to ensure that it has no moisture retention that can later damage the laminate planks.

You can do this by checking the humanity; if the meter reading shows something more than 4.5%, then you have a moisture problem and need to resolve it before installing the floor.

Once you are done with a moisture test, then you have a green light to go ahead with your process.

You can start the process of installing a plastic vapor barrier, which can be around 6mm thick. The laminate flooring your choose should ideally go well with any manufacturer-recommended underlayment.

Try using vinyl tape to secure the underlayment from coming out. It also adds a little padding that makes the flooring a lot more comfortable to walk on.

How to Take Care of your Laminate

Laminate flooring is a great option. You can ideally install them in any room that does not deal with a lot of moisture. Try to keep it away from laundry rooms, yards, balconies, and bathrooms.

While its material is durable and long-lasting, it does have certain ways you can maintain it.

Many people wonder what the best way to clean the laminate afterward. Try using a slightly damp mop or a micro-fiber cloth that can clean off any stains.

Ideally, you should not let liquids sit on the flooring for too long, as they can be absorbed in. In addition to this, also avoid polishing or waxing the floor.
