Cornerstone Promix Fibred Basecoat Render & Plaster 25kg

Cornerstone Promix Basecoat Fibered is a dry ready mixed lime render and plaster designed as a coarse basecoat or floatcoat within an appropriate render system. Available in the colour white. Engineered with precision utilising 100% pure natural hydraulic lime, natural sands, conservation-appropriate additives and fibres. The enhanced physical and mechanical characteristics create a high-performance, breathable basecoat render. The addition of fibres assists with mitigating cracking and shrinkage while improving the stress distribution of the render. Available as standard with Saint-Astier® NHL2 or NHL3.5. Other binders and mix ratios are available upon request. Well-suited as a fibered basecoat for additional reinforcement and improved tensile strength, especially for high-suction backgrounds. Conservation appropriate additives Fibres assist with mitigating cracking and plastic shrinkage Improved stress distribution Vapour permeable to support moisture management Features the feel of a modern mortar No-fuss levelling and finishing Decreased likelihood of slump Enhanced workability for those behind the trowel Extended working and finishing time Promotes even curing for an improved bond Technical Information: Materials: Natural Hydraulic Lime, Natural Sands, Additives Mix Ratio: 2:5, others available on request Binder: NHL2, NHL3.5, others available on request Aggregate: 4mm down washed silica sand Work: Rendering, Plastering Coverage: A 25kg bag covers approx. 1.5m2 at 10mm thickness Yield: A 25kg bag yields approx. 15 litres Colours: Off-white Use: Internal, External Coat: Basecoat, Topcoat Standard: BS EN 998-1: 2016 Fire Rating: A2 Application: Manual Area of Use: Suitable for internal or external use, where the binder strength is appropriate for the host background or surface. Promix Basecoat Fibered suits various rendering and plastering applications including coarse render coats, dubbing out, scat coats, scratch coats and float coats where a fibered mix will be appropriate. For a non-fibred basecoat with a refined white finish, explore Promix Coarse Basecoat. Appropriate for various project types, including conservation, renovation, or sustainable construction. A 25kg bag yields approximately 15 litres of lime render or plaster and covers roughly 1.5m² at a 10mm thickness. Consumption rates will change based on how even the background is and suction. On-site trials are advised for the best yield indication for your specific project. As natural products, our kiln-dried sands may exhibit variations in colour, texture, and shape. While these variations are minimal, when colour consistency is crucial, we strongly advise each elevation is completed using material from the same batch. Supplied in 25kg polythene-lined and colour and batch-code paper bags for easy identification on-site and palletised for ease of transport, storage, and handling. FIBC tonne bags are also available. Do not use in temperatures below 5°C or above 30°C, or if freezing conditions are predicted within the following few weeks, including wind chill. We always advise following best practices for curing and protecting fresh lime renders and plasters. Protect from adverse environmental conditions, including frost, rain, direct sunlight and drying winds. Store in covered and dry conditions, protected from environmental conditions, including water, damp or frost and clear from the ground. Always reseal packaging if product is still present. Always read the available documentation before use. See the Download Documentation section below for more detailed product information, application guidance and datasheets.
