5 Best Underlayment For Laminate Flooring On Concrete

Concrete subfloors are noted for their strength and durability. They are permeable, though, and are sensitive to moisture damage. Linoleum, carpet, wood, tile, stone, or marble are all suitable alternatives for concrete floors.

Concrete can be painted almost any color, resurfaced in a wide range of styles and finishes, or polished for a smooth, lustrous appearance. Concrete flooring is also durable, easy to clean, and maintain. If your subfloor is concrete, search for an underlayment that will act as a moisture barrier between the laminate and the subfloor.

We’ve included the best underlayment for laminate flooring on concrete in this article, along with their numerous features, which you can learn about by reading through each item.

Types of Underlayment for Laminate

When it comes to floor coverings such as tiles, laminate, wood, or resinous coatings, it may appear that the floor covering is more significant than the subfloor. In fact, there are so many distinct floor covering options that there must be a variety of underlayment options as well.

The underlayment is important to the success of any flooring installation. Because the underlayment is the foundation upon which the entire installation is built, it is more likely to succeed when it is solid.

There are numerous varieties of underlayment from which to pick. Foam, cork, and plywood are the most popular. Many underlayment products combine all three elements. The fundamental function of an underlayment is to absorb sound or the faint echo created by walking on the floor.

An underlayment protects the floors from moisture that could cause buckling or damage. Moisture insulation is a feature of the best laminate underlayment’s. If your flooring is concrete or a slab, you will make sure your underlayment has a damp-proof membrane.

This will protect your floors from dampness even more. If your subfloor is made of wood, you won’t want a damp proof membrane because wood needs air to avoid mold. Always check your moisture levels before installing laminate flooring underlayment.

How to Prepare a Concrete Subfloor

It is necessary to have a clean, dry, and flat concrete subfloor when installing laminate. This will not only ensure that your new flooring looks its best, but it will also ensure that it lasts longer.

Subfloor Cleaning

It’s best to try to clear up any old paint, adhesive, or wax left over from prior flooring, especially if your new floor is being fitted with adhesive.

This can be done with a scraper, followed by a heavy-duty sander or concrete grinder. If you don’t have one, you may borrow one from most tool rental stores, which are easy to find.

Level your subfloor

It’s important to have a flat concrete subfloor for a great finish. Otherwise, any flaws in your new flooring will be obvious.

A long level and tape measure are the best tools for this. Every 10 feet, the floor should be uniform to within a quarter inch. Even out any high places with a heavy-duty sander or a concrete grinder. Before doing anything further, use a floor leveling product to fill in any low spots and let it dry completely.

Dry

Before laying any type of flooring, make sure your concrete is dry. This is particularly important for laminate and wood, as moisture is highly damaging.

If the subfloor is new, it should be left for at least 30 days before installing new flooring. To assess the moisture levels, use a moisture test kit. You’ll need to lower the room’s humidity and wetness if they’re not within the laminate or wood manufacturer’s standards.

Structurally Sound

It is, of course, vital to maintain that your subfloor is physically solid and suitable for its intended use. If you’re moving into a new home or haven’t updated your floor in a long time, you may not be aware of the subfloor’s condition. Before you begin laying your new floor, inspect it for cracks and crumbling.

Concern Areas for Concrete Slabs

Understanding your concrete subfloor will help you choose a durable and appropriate underlayment. In order to choose an underlayment for concrete slabs, you must first consider some of the most typical issues that concrete floors offer.

Moisture Substrate

Moisture is the first factor to consider. Concrete, despite its appearance, is a permeable material that can retain and expel moisture. Due to high humidity or ground moisture, water may seep into your concrete slab. This is particularly true if your basement floods or leaks frequently during heavy rain. When moisture is absorbed by a concrete slab, it can be retained for a surprising amount of time. Installing the improper type of flooring over wet concrete can lead to warping and wear over time.

Fortunately, a wide range of flooring materials are water-resistant enough for use over a concrete slab. You can set your flooring up for success by combining resilient flooring types with additional protection strategies such as waterproofing membranes or barriers.

How to Prevent Concrete Floor Moisture Issues

  1. Allow time for the concrete slab to dry

While speeding up the concrete slab’s drying process may boost productivity, allowing it to dry naturally may prevent moisture issues. Give the concrete slab the time it needs, and if necessary, reassess the project plan and timetable. Controlling the environment may help to speed up the natural drying process.

  1. Select the appropriate vapor retarder

It’s important to remember to use the correct vapor retarder. Make sure you stick to the perm grades that are appropriate for the location. Another issue to consider is the vapor retarder installation. The installation should be done on top of a fill layer. Before pouring the concrete, inspect the vapor retarder for any rips and repair them.

  1. Use damping agents

Damping agents may also aid in the prevention of moisture problems in slabs. This will form a water-resistant coating on top of the concrete slab, preventing moisture from entering. For an existing concrete floor, this procedure includes cleaning the top and applying a damping agent. Depending on the amount of moisture in the concrete, additional layers may be required.

  1. Install proper underlay

Installing a good underlay between the concrete slab and the flooring would provide additional protection if wood flooring is being used. The best option could be a laminate underlayment that has been tested to ensure it will not absorb any additional moisture.

Flatness

Some flooring styles may exaggerate unevenness if your concrete slab isn’t entirely flat. Even minor grade differences can be magnified following flooring installation. Check to determine if your concrete slab is level to aid with your flooring choices. If you see any uneven patches, consider a more forgiving flooring option such as carpet or vinyl.

FAQS

Is it possible to lay an underlay on a concrete floor?

With laminate floors, you should apply a thin underlay regardless of the subfloor. Concrete, on the other hand, must have a moisture barrier. It’s because concrete subfloors exude moisture that, if incorporated through the laminate boards, can be quite harmful.

Is a Concrete Floor Right for You?

If you have an established slab foundation and a home style that complements the glossy shimmer of honed concrete, a concrete floor can be an excellent alternative. Concrete floors are popular because of their low cost, especially when considering their extended durability. It’s possible that you’ll never need to replace your flooring. Be prepared, though, for a naturally cold and very hard floor.

Can You Put Laminate Flooring Directly on Concrete?

It is possible to lay laminate flooring directly on top of concrete, although it is not advised. Because concrete is porous, it absorbs moisture and causes vapor damage to your laminate boards. Instead, we recommend putting underlayment between the concrete flooring and the laminate planks to act as a vapor barrier.

Conclusion on Best Underlayment For Laminate Flooring On Concrete

Among all flooring options, a concrete floor is the most cost-effective. In comparison to other common flooring materials, a new slab of concrete is less expensive. Concrete sub-floors are not suited for all underlays. We have compiled a list of our preferred concrete floor underlays.

Most crucially, each of these concrete underlays comes with a built-in vapor barrier to safeguard your wood or laminate flooring. It’s still necessary to check that your sub-moisture floor’s levels are within the manufacturer’s guidelines and that there are no damp issues.
