What Causes a Floor Tile to Loosen?

Many homeowners have requested me, “Why do flooring tiles loosen?” It is superb to me, with the advances in ground preparation and modified mastics, that tiles can nonetheless come loose. It is attainable to understand why flooring tiles come unfastened with out using the assistance of a flooring skilled or basic contractor. Permit me to tell you why this happens.

First, it is very important perceive what holds the tile to the floor. Tiles, whether made of ceramic, porcelain, slate, granite, or marble, are all held in place by a substance called thin set. Thin set is a Portland cement based material containing a particular mix of additives which give the mixture the flexibility to softly flex beneath strain and return to its authentic position. This strain, often known as load, might be the result of climatic modifications, such as the passing of the seasons, or from a physical nature, such as the load of an individual or merchandise positioned on the tile.

Typically the strain or load might be too much for the thin set. If a heavy object is positioned on the tile ground, reminiscent of a piano, it is vitally potential to overload an individual tile. If this happens, the bond between the tile and the thin set may be damaged and the tile can sheer away. Once sheered, the tile won’t ever re-bond with the thin set. The result is a loose tile solely held in place by the grout surrounding its four sides.

Subsequent, the construction of the floor must be considered. Before putting in any type of tile flooring, the contractor or flooring skilled should survey the sub floor. The sub floor must be built inflexible enough to assist its own weight, the weight of the tile, and the load of the objects placed on it. Most native codes state that if the ground is framed with 2×8 floor joists, sixteen” on heart, and sheeted with a 5/eight” plywood materials, it may be tiled. Bear in mind, earlier than beginning any construction project, check together with your local building code officials. Better secure than sorry.

In many homes, the Floor installation just isn’t constructed or framed robust enough to assist its personal weight and the burden of a tile floor. When flooring should not framed sufficiently they have an inclination to move perpendicular to the aircraft of the earth. This up and down motion stresses the bond between the tile and the thin by as applying an excessive amount of weight or load in one area.

The bond between the tile and the thin set could very nicely be sturdy enough to simply accept an overload a number of times. The number of occasions is directly related to the standard of the thin set. Inevitably, even the most expensive thin units will fail if subjected to continuous overloading.

Last, the commonest reason why a tile will loosen from its thin set is improper installation. Careless contractors are likely to tile weak floors. The thin set must be mixed according to producer specification. If blended too moist or too dry, the thin set is not going to properly cure. This improper curing results in a weak floor.
