Finishes - Installing porcelain or ceramic tiles on a Limecrete floor

For tiles that have very low suction such including porcelain or ceramic tiles, lime-based adhesives are not advised as they can have issues bonding to the surface. In these instances, conventional tile adhesives should be used following the manufacturers recommendations for installation. Most conventional adhesives are not breathable or have limited breathability so it is important to ensure the slab is completely dry before installing these finishes.
