The flooring that you install in your home should last several years before you even have to consider replacement. If your flooring isn't lasting that long, chances are, you aren't choosing the type of flooring that will fit into your lifestyle very well. This blog is all about choosing flooring that will fit into your lifestyle and last you many, many years before you have to rip it up and replace it. You will also find tips for keeping it looking like new as it survives the abuse that your family, friends and pets put it through during the course of the year.
A common challenge with installing tile flooring directly on top of a concrete slab is that there is naturally a certain level of moisture present. This is in part because concrete is semi-porous, so some ground moisture will penetrate the concrete. Although this isn't enough moisture to cause wetness or water damage, it can affect the adhesive that is used to hold your flooring in place. The following are some strategies that can help mitigate this issue.
1. Moisture Measurements
Your contractor should measure the moisture in the slab before they begin any flooring installation. The test requires taking a moisture reading for one or two days when temperatures in the house are at standard room temperature, usually around 70 to 75 degrees, and at average humidity. The higher the moisture levels measured during the test, the more likely additional measures must be taken to ensure your tile adhesive is strong enough to keep your flooring in place. Moisture is measured in Relative Humidity (RH) percentages, with the higher percentage number indicating the more moisture present in the concrete subfloor.
2. Moisture-Proof Adhesives
A common strategy to overcome higher RH percentages is to use a waterproof tile flooring adhesive. Your contractor will need to choose an adhesive formulated for the RH in your home and the type of flooring being installed. Fortunately, tile adhesives tend to come in a wider range of waterproof capabilities compared to adhesives made for carpeting. This is in part because tile floors are often installed in high-humidity rooms, such as the bathroom. Many floor tile manufacturers recommend specific adhesives for their tiles, as the tiles were constructed to work best with certain waterproof products.
3. Vapor Barrier Installation
If the RH percentage is very high in your home or the room, waterproof adhesive may not be enough on its own. In this case, your contractor may recommend installing a vapor barrier over the concrete subfloor before installing the tile. The barrier may consist of a paint-on water sealing product, which can go on quickly. Then, your tiles will be installed in a day or two after the sealant has cured. For more severe moisture issues, your contractor may instead install a waterproof membrane that will effectively encase the subfloor so no moisture leaks in. That way the waterproof adhesive has the best chances for success.
