What Causes a Floor Tile to Loosen?

Various owners have asked myself, “Why do floor floor tiles loosen? ” It’s amazing to me, with the advances in floor prep and modified mastics, that tiles can still come loose. It is possible to understand why floor tiles come loose without employing the help of a flooring professional or general contractor. Allow me personally to tell you why this happens. Flooring Roseville

First, it is important to comprehend what holds the tile to the floor. Tiles, whether made of ceramic, porcelain, slate, granite, or pebble, are typical held in place by a substance called thin set. Thin collection is a Portland concrete based material containing a special blend of chemicals which give the mix the ability to softly flex under strain and return to its original position. This strain, also known as load, can be the result of climatic changes, including the spending of the times of year, or from a physical nature, including the weight of a person or item located on the tile. 

Sometimes the load or load can be too much for the skinny set. If a heavy object is located on the tile floor, for instance a piano, it is very possible to overload an individual tile. In such a circumstance, the relationship between the tile and the thin set can be broken and the tile can sheer away. Once sheered, the ceramic tile will never re-bond with the thin set. In this way a loose tile only held in place by the binding material surrounding its four edges.

Next, the structure of the floor needs to be regarded as. Before installing any type of tile floor, the contractor or floor professional should survey the sub floor. The sub-floor must be built tight enough to support their own weight, the weight of the tile, and the weight of the items put onto it. Just about all local codes claim that if the floor is frame with 2×8 floor joists, 16″ on center, and sheeted with a 5/8″ plywood material, it can be tiled. Remember, before starting any construction job, check with your local building code officials. Better safe than sorry.

In many homes, the floor just isn’t built or framed strong enough to support its weight and the weight of a tile floor. When flooring are not framed completely they tend to move perpendicular to the aircraft of the earth. This kind of up and down movement stresses the bond between the tile and the thin by as making use of too much weight or load in one area.

The bond between the tile and the slender set may very well be strong enough to accept an overload a few times. The amount of times is straight related to the quality of the thin place. Inevitably, even the most expensive thin sets will fail if subjected to continual overloading.

Last, the most frequent reason why a ceramic tile will loosen from the thin set is incorrect installation. Careless contractors usually tend to tile weak flooring. The thin set needs to be mixed regarding to manufacturer specification. In the event mixed too wet or too dry, the slender set will not properly cure. This improper stopping results in a poor floor.

Over time, most tiled floors will have a tile pop loose. This is to be expected and can be repaired. If over the life of a floor, many tiles pop loose, a more serious problem is the reason. In my experience, human error is the cause.
