Defects and Misapplication of Microcement

Microcement is an innovative and versatile coating that has become a popular choice for modern renovations and designs. Its seamless finish, free of joints, makes it hygienic and easy to maintain, while offering a wide range of colors and textures. However, issues caused by poor application, such as cracks, stains, or unwanted marks, have created some skepticism about this material. Most of these problems stem from application errors or the use of low-quality materials.

Why do these issues occur?
One common mistake is the appearance of tile joint marks on tiled surfaces, caused by the difference in absorption between the tiles and their joints. To avoid this, it is essential to fill the joints beforehand and apply a proper bonding primer to create a uniform base.

Another frequent issue is the presence of undesired ridges or relief caused by improper use of the trowel. The solution is to sand between each layer of microcement, detecting irregularities by touch. For the final layer of fine microcement, this process must be carried out with extreme care to achieve a perfectly smooth and even surface.

Additionally, stains and marks can appear due to errors in the sealant application, such as not respecting drying times, improper product application, or leaving excess material when rolling. Changes in the microcement’s tone can also occur, often due to incorrect mixing ratios.
