Mapei Novoplan 21 Fast Hardening Self Levelling Smoothing Compound 25KG

Descriptions
• Novoplan 21 is a grey powder comprising of special fast-setting and hydrating cements, specially graded silica sand, special resins and additives prepared and developed in the MAPEI research laboratories.
• When mixed with water, Novoplan 21 becomes a very fluid, easily workable mix with excellent self-levelling properties and cures rapidly.
• Novoplan 21 can also be applied with an appropriate pump.
• Novoplan 21 is strong enough to withstand wheelchair traffic.
• Novoplan 21 can be applied in thicknesses up to 5 mm per single coat without significant shrinkage that might cause cracks or crazing.
• Once completely dry Novoplan 21 has good compressive and flexural strength as well as resistance to impact and abrasion.
• Flooring can be installed once Novoplan 21 has dried, after 24-48 hours, depending on the thickness, temperature and moisture of the environment.

Features
• Self-Leveling: Novoplan 21 is formulated to level itself after application, helping to create an even surface with minimal manual intervention.
• Quick Setting: It’s designed to set quickly, allowing for faster project completion and earlier installation of floor coverings.
• High-Strength: The mixture provides a durable, resilient surface that can withstand typical interior foot traffic and floor loads.
• Application Thickness: It can be applied in thicknesses ranging from feather edge up to 1 inch in a single pour. For thicker applications, it can be applied in multiple layers.
• Low Shrinkage: The formula minimizes shrinkage, which helps reduce the risk of cracks as it dries.
• Compatibility: Suitable for use on a variety of substrates, including concrete, cement backer board, and properly prepared wood subfloors.
• Versatile Usage: Ideal for both residential and commercial settings where a smooth, flat substrate is necessary.
• Improved Flow and Workability: It is easy to mix and pour, which makes it efficient to use over large areas with consistent results.
• Environmentally Friendly: The product is low in volatile organic compounds (VOCs), making it safe for indoor use with minimal odor.

Where to use
• Interior levelling of new or existing substrates to make them ready to receive resilient or textile flooring in areas where a good resistance to loads and traffic in offices and public areas is required.
• Levelling existing flooring in terrazzo tiles, ceramic tiles, natural and magnesium stone.

Some application examples
• Smoothing of concrete slabs and cement-based screeds or Topcem, Topcem Pronto, Mapecem or Mapecem Pronto screeds.
• Smoothing of anhydrite screeds.
• Smoothing of under-floor heating installations.
• Smoothing over existing ceramic tile, terrazzo, natural stone and magnisite floors.

​​​​​​​​​​​​​​Recommendations
• Do not add more water to the mix once it has begun to set.
• Do not add lime, cement or gypsum to the mix.
• Do not use for smoothing in exteriors or for substrates subject to rising damp.
• Do not apply another coat of Novoplan 21, once the previous one has dried completely, without first applying diluted Primer G (1 part by weight of Primer G diluted with part water).
• Do not use Novoplan 21 at temperatures below +5°C or above +35°C.
• Not suitable for installing wood and parquet floor and wall coverings.
• Do not apply Novoplan 21 in thicknesses less than 1 mm.
• Do not use for levelling over wooden substrates.
