Silin Lasur
Mineral Stain for Masonry

Cathedral Stone Products® Inc. introduces Silin® Lasur Stain, for use on masonry, stucco, and plaster. The Lasur stain is ideal for interior and exterior surfaces plastered with cementitious mortars. The stain is completely inorganic and after drying, produces a flat finish. The glaze is non-flammable and does not develop toxic gases. The Silin® Lasur silicifies with the substrate and preserves its breathability.

Application is by brush, roller and airless sprayer. For more decorative finishes, the use of sponges and brushes are acceptable.

Application Procedures

Surface Preparation
All mineral surfaces are suitable if they have cured and are clean, solid, dry and absorbent. Wood, plastics or oil paints and enamel coatings are not suitable as a substrate. For substrates containing gypsum, contact us for special assistance. Repairs of the plaster have to be executed with an adequate mortar. The surface of the repaired areas should match the texture and color of the existing surface. Hairline cracks must be repaired prior to application. Silin Lasur must be applied to clean masonry surfaces. Any previous coating must be removed prior to application. Temperature (ambient and substrate) must be at least 45° F (8° C). Do not work in the direct sun. Always maintain a wet edge when applying Lasur. Do not apply under wet conditions.

Mixing
The ratio of the mixture between Silin® Lasur and Silin® AZ-Fixative depends on the desired effect of the stain. The more Silin® AZ-Fixative used, the more transparent the stain. Different substrates with varying degrees of porosities will also have a greater or lesser effect on the color. To avoid a glass effect dilute Silin® AZ-Fixative with water. Colors should be tested and adjusted on site.

Clean Up
Place tools in clean water when stopping work. Clean tools with clean water immediately after finishing work. Dried Silin® Lasur is insoluble in water.

Coverage
The coverage depends on the proportion in the mixture and the absorptive capacity of the substrate. The exact quantities needed have to be determined on a trial area.
