Abstract
A method in dry shake coating of a concrete floor is provided. On top of the concrete floor two or more superimposed dry shake material layers are applied. The surface of an underlying dry shake layer is troweled prior to application of a next dry shake layer, whereafter the lastly processed dry shake layer of a concrete floor is troweled. The application of an underlying dry shake layer is followed by spreading over its surface a water soluble silica-based medium prior to and/or during the course of troweling this particular dry shake layer and prior to the application of an overlying dry shake layer.
Claims6
A method in dry shake coating of a concrete floor, said method comprising:
- spreading an underlying layer of dry shake material on top of the concrete floor surface;
- spreading a colloidal silica-based medium over the surface of the underlying dry shake layer before and/or during troweling the dry shake layer and before applying a next dry shake layer;
- troweling the surface of the underlying dry shake layer followed by applying the next dry shake layer;
- troweling the lastly spread dry shake layer of the concrete floor;
- wherein
- the colloidal silica-based medium enhances bonding between sequentially-applied dry-shake layers and enables increasing an overall thickness of the dry shake coating.
