When it comes to quality checking porcelain tiles, there are several factors that you should consider to ensure that you are getting a high-quality product. Here are some things to look out for:
Water absorption rate:
Porcelain tiles are known for their low water absorption rates, so it's important to check the manufacturer's specifications to ensure that the tiles you are considering have a water absorption rate of less than 0.5%.
The thickness of porcelain tiles can vary, so it's important to check that the tiles you are considering are the correct thickness for your project. Thicker tiles are generally more durable and better suited for high-traffic areas.
The surface of porcelain tiles should be flat and level, without any dips, bumps, or lippage (uneven edges). To check for lippage, lay the tiles out on a flat surface and run your hand over them to feel for any differences in height.
Porcelain tiles should be straight and not warped or bowed. You can check for warping by placing the tiles on edge and looking down the length of them.
If you are purchasing a large quantity of porcelain tiles, it's important to check that the color is consistent across all the tiles. Look for any variations in color or shading that could affect the overall appearance of the finished project.
Check the surface of the porcelain tiles for any defects such as cracks, chips, or scratches. These defects can weaken the tile and affect its durability.
Porcelain tiles are rated based on their hardness and durability, with the most durable tiles being rated as Class 5. Check the manufacturer's specifications to ensure that the tiles you are considering have a high enough rating for your intended use.
By checking for these factors, you can ensure that you are getting a high-quality porcelain tile that will meet your needs and last for years to come.
