DIY microcement: real savings or a guaranteed botch job?
The recipe is all over YouTube: one part white cement, three parts Aguaplast (or powdered plaster) and paint to taste. The result promises the industrial finish of microcement at a fraction of the price. But practice reveals a fundamental problem: the mix lacks the flexibility and adhesion of the professional product. Those who have tried it on decorative walls rate it as fine; on floors, it's a different story. Cracks appear quickly, and the loss of thermal comfort is real when applied over plaster. Alternatives such as tadelakt, a polished Segarro stucco, gain ground for bathrooms and damp areas, although its application is more artisanal. The temptation of pristine white or cement grey clashes with reality: any mixing or curing mistake takes its toll on the aesthetics. Fake microcement only works on surfaces with no traffic or moisture, and always with a quality polyurethane coating. For floors, the sensible option is genuine microcement or a self-levelling compound. Short-term savings can turn into a mid-term headache. Is it worth risking your renovation for pennies?
