Every ceramic tile manufacturing center is obliged to have a quality testing unit. Method of examination Visual inspection with a wet-dry balance is required to determine the amount of moisture contained in ceramic tiles. Taking two samples from each tile and placing them in separate containers, then weighing them at both room temperature (25°C) and hot water temperature (95°C), can be used to determine the amount of moisture in the tile. The amount of moisture present in each sample accounts for the disparity in their respective weights. Before making any tile purchases, a test of the ceramic tile should be carried out. Additionally, if you intend to paint or stain the floor of your bathroom, you should wait to do so until after the test has been completed. Paints and stains are known to have adverse reactions when exposed to excessive quantities of moisture. Different kinds of tiles 
The kinds of materials that are used to make different kinds of tiles results in a large variety of tile varieties. There are three primary categories of tile, each of which has a unique set of advantages and disadvantages. These are pieces of porcelain, natural stone, and cement that was manufactured. Porcelain tiles are the sort of tile considered to be of the greatest quality, as they have the fewest number of flaws and imperfections. However, in comparison to the other kinds of tiles, they are the most expensive. Cement tiles are more affordable than porcelain tiles, but because they require less labor to produce, they are more likely to break and warp over time. Tiles made of natural stone are sometimes the least expensive alternative available online; nevertheless, they do not have the same degree of durability as porcelain or cement tiles. Natural stones are easily damaged by abrasions and chips, and they cannot tolerate an excessive amount of foot traffic. Before you buy tiles for your bathroom flooring, you should think about having them inspected by a professional first. This will help you avoid purchasing tiles of a low quality. According to the results of our illustrative test, the levels of moisture present in the tiles ranged from 33 percent to 38 percent. It was presumed that these tiles had been kept in a sanitary environment over the years due to the fact that they had been acquired from nearby stores. The tiles were solely examined for their level of moisture content as a result of this. After they have been cleaned and dried, you should consider making another trip to the store in order to examine the surface quality of the tiles. Tile variety The majority of ceramic tiles fall into one of two categories. Porcelain is the name of the first category. Porcelain is the name given to tiles that have been non-porous and impermeable as a result of having been fired at temperatures of 1800 degrees Celsius or greater during their initial production. 
These tiles have been used since ancient times; but, because it requires a lot of energy to fire ceramics, they aren't utilized very frequently in modern construction. The fragile quality of these tiles makes them susceptible to cracking over time, which is yet another drawback associated with their use. The natural clay tile is the second kind of tile that may be purchased. Because natural clay tiles are not subjected to high temperatures during the firing process, they have a porous and leaky appearance. Even though this means that they do not need products that seal the gaps, they still need to be maintained. The pores in natural clay tiles eventually become clogged with dirt, chemicals, debris, and water throughout the course of their lifetimes. When something like this occurs, the tile quickly deteriorates and has a larger pore size. Because of the increased pore size, the tile becomes more difficult to clean with time. Regular maintenance cleaning is required for natural clay tiles. Tiles made of natural clay are frequently seen in domestic settings including bathrooms, kitchens, and even laundry rooms. Because the tiles are porous, they do an excellent job of retaining moisture and do not require any kind of sealing agents. Additionally, they are resistant to the accumulation of stains. Even if you have dogs, natural clay tiles are an option for you to consider because they do not retain scents. However, due to the fact that they are porous, cleaning is essential in order to maintain their pristine appearance. Grading Weight per square foot is the standard unit of measurement for the ceramic tile grading system. There are three distinct quality levels available for the tiles. Tiles of grade I weigh between 0.8 and 1.0 ounces per square foot as measured in square inches. Tiles of grade II weigh 1.3 ounces per square foot, while tiles of grade III weigh more than 1.5 ounces per square foot.

In order to ascertain the weight of the tile, tile testing needs to be performed by a trained individual. A bathroom scale is used to determine the weight of each tile, and the results are recorded. The tile's surface area is determined subsequent to its weight being recorded. To accomplish this, simply multiply the length by the width. The thickness of the material is measured after that. Divide the length by the breadth by the height to get the thickness of the object. In the final step of the calculation, the total volume of the tile is determined by multiplying the surface area by its thickness. After passing all of the tests, the tile will next be ranked according to the density it possesses. The Preparation of the Surface The surface of the tile needs to be prepped so that sealants and paints may be applied afterwards. Sanding the tile is an effective way to remove any loose paint or remnants of glue. This step is essential because, if the tile in question has any flaws, you can wind up needing to replace the whole piece. Sanding helps restore the finish of the tile, which is helpful in cases when the tile has rust or scratches. The tile needs to be treated first before any sealers or paint are applied to it in order to get it ready for painting. When prepping the tile, any loose material is removed. Everything from crumbled mortar to dust is included in the debris that is taken from the site. It is in the tile's best interest to apply sealants only after the tile has been thoroughly cleaned and prepared. 
Comparing Paint to Sealers The question of whether sealers or paints should be used is one that is frequently debated. If you decide to go with a floor coating, you have the option of selecting either a sealer or paint for the project, depending on what it is that you want to achieve with the finished product. A sealer is very much like a varnish in its function. It offers the tiles an elegant appearance while also helping to protect them from stains and fading. Paints, on the other hand, are considerably more watery than sealers, and their purpose is to give your floors color and sheen.
