Tiling is a job that involves the installation of tiles, such as ceramic, porcelain, or stone, to walls and floors. Spackling is a part of this job, which involves filling in any gaps between the tiles with a spackling compound. This compound is usually made of gypsum, plaster, or cement, and is used to create a smooth, even surface. Spackling is an important step in the tiling process, as it ensures that the tiles are properly secured and that the finished product looks professional.
