The inclusion of the acrylic allows you to achieve significant savings. The flow rate of the mixture becomes much less. While the appearance of Venetian plaster remains unchanged. Besides polymeric backing prevents the appearance of microcracks.
The beginning of work ↑
A special role when applying Venetian plaster is the quality of the mixture and its texture. Therefore, the construction process begins in the store when you pick up the necessary sample mixture.
