Introduction Microcement in showers is a cement-based coating that creates a continuous, waterproof surface over failure-prone areas. This article explains how to plan the work, coat the walls and floor, and spot potential trouble before sealing. Common waterproofing approaches in showers include membrane types you can install under microcement, but check compatibility with your product

Introduction Sorptivity is a measure of how quickly a porous material absorbs water through capillary action. In this DIY intro, we’ll keep the test simple and describe what you can observe on a small patch of concrete or plaster. The goal is to get a practical sense of absorption behavior without high-tech gear. Results help
