The most common reason is non -compliance with technology. A dry grouting mixture is added to a strictly measured amount of water, thoroughly stirred manually, a mixer or a drill with a nozzle. After that, leave the mixture for 5 minutes for ripening and mix again. The finished composition must be used for a certain time.
Gradually, he thickens, which complicates his work with him. At this stage, non -professionals make a mistake – add water again and mix the solution. But this cannot be done, since it is excess water that leads to a deterioration in technical characteristics. Diluted with water grouting over time will inevitably crack. To avoid problems, it is worth mixing the solution more often or preparing it in small portions, strictly observing the ratio of water and the mixture.
