Composition & Features

• Mixture of high quality white cement, crushed marble with selected granule size, enriched with polymers and other special improving additives. • It complies with specifications: EN 998-2:2003, M10, W2. Granule size <0.7 mm.

Application

• The substrate must be clean and firm. • The contents of a bag are mixed with clean water (approximately 5.5-6.0 l/bag) using an electric mixer at low speed or a traditional mixer until a homogeneous mixture is obtained. The mixture remains workable for 3 to 4 hours (depending on the ambient temperature). Periodic stirring without adding additional water is required. The mixture is applied with a simple or serrated trowel. • The application of POROBOND 50 and the positioning of the structural elements in their final position should be completed within a maximum of 10-12 minutes. • The final surface should be protected from rapid water loss as well as extreme weather conditions. If necessary, the surface should be wetted with clean water. • At the application stage, the temperature should be between +5 oC and +35 oC.
