Products: Sandstone Render Product Description: Micro Milling Sandstone Render is a precision blend of Portland Cement, Processed Sand and Special Additives manufactured under stringent controls to ensure consistency and quality. Our Sandstone Renders are available in two colours as well as two textures.  Sandstone Renders include: Coral Fine Coral Coarse Tan Fine Tan Coarse Application: The product is suitable for external and internal use over traditional sand/cement plaster, brickwork, blockwork and concrete substrates prepared and suited to receive a rendered finish. In particular the surface to be rendered must be clean, free from paint, oil, dust or anything likely to prevent a satisfactory bond. Apply the product to a uniform thickness of approximately 10-12mm (3/8" - 1/2"). Float to an even surface with a wood float. When render has set but not become too hard, scrape the whole surface evenly with a scraping tool to produce a uniform texture. In common with traditional sand/cement renders, this render should be applied in a continuous process to avoid dry line jointing. If breaks cannot be avoided they should be made where surfaces or architectural features, such as reveals or lines of doors and windows help mask joints. Where long uninterrupted runs are planned, material used should be from same batch. On completion of the rendering, the surface must be checked to ensure an even coverage of render. Coverage: One 22.5kg (50lbs) bag of render applied 10-12mm (3/8" - 1/2") will cover approximately 1 square meter (10.5 square feet). Mixing: The product should be added to clean water at a rate of approximately 3.5 litres (0.75 gallons) of water to a 22.5kg (50lbs) bag and thoroughly mixed with a mechanical mixer for a minimum of five minutes until correct workability is achieved. Slumping of material may occur if the mix is too wet and will increase the risk of settlement cracks developing. Packaging: Micro Milling Sandstone Render is packaged in 22.5kg (50lbs) - multiwall paper sacks with a moisture barrier to ensure a long shelf life. The product should be stored in dry conditions, above the ground in well-ventilated areas. Shelf life is approximately six (6) months if stored properly.
