Product Description

Mapei Novoplan 21

WHERE TO USE

Novoplan 21 is used for levelling and smoothing new or existing substrates and provides an underlayment for receiving PVC, linoleum, rubber, cork, textile and non-woven flooring in areas where a good resistance to loads and traffic in offices and public areas is required. Novoplan 21 must only be used in interior conditions in thicknesses from 1 to 5 mm. 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 magnesite floors.

TECHNICAL CHARACTERISTICS

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.

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 3 parts 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.

APPLICATION PROCEDURE

Preparing the substrate The substrates must be dry, solid, free from dust, loose materials, paints, wax, oils, rust and traces of gypsum. Cement based surfaces which are not sufficiently solid must be removed, or wherever possible, consolidated with Prosfas, Primer EP or Primer MF. Cracks or crazing in substrates must be repaired with Eporip. In order to fix dust and to provide uniform absorbency of the substrate, dusty or very porous concrete surfaces must be treated with a coat of Primer G (1 part Primer G with 3 parts of water) or with Livigunn (1 part Livigunn with 5 parts water). Anhydrite screeds can be levelled with Ultraplan only after the application of a coat of Primer G or Primer EP. On existing ceramic or natural stone surfaces apply a coat of Mapeprim SP after the surfaces have been cleaned with detergents and mechanically abraded. Level before Mapeprim SP has dried completely (it must still be tacky).

Preparing the mix

While mixing with a low speed electric mixer, pour a 25 kg bag of Novoplan 21 into a bucket containing 6.25 -6.50 litres of clean water and mix until a uniform lump-free paste is obtained. Larger quantities of Novoplan 21 can be prepared in suitable mortar mixers. Let the mix stand for several minutes before remixing for a short time, the mix is then ready to be applied. The amount of mixed Novoplan 21 must be used within 30 minutes (at a temperature of +23°C). Applying the mix Apply Novoplan 21 in a single coat from 1 to 5 mm thick with a large metal trowel or a squeegee, keeping the trowel slightly inclined to obtain the desired thickness. Novoplan 21 can be also applied with a suitable pump. When a second coat is required, it is recommended to apply it as soon as the previous coat is set to light foot traffic (approx. 3 hours at +23°C). Installing the ooring Once Novoplan 21 dries, resilient, textile and ceramic flooring can be installed over it. All of the MAPEI adhesive products are designed to be applied over Novoplan 21. Waiting time before installation can vary according to the humidity and ambient temperature, and the thickness and type of flooring to be installed (from 24 to 48 hours). Cleaning While it is still fresh, Novoplan 21 can be removed from tools with water.

CONSUMPTION

1.6 kg/m2 per mm of thickness.

PACKAGING

Novoplan 21 is available in 25 kg bags. STORAGE 12 months in a dry place and unopened packing. Novoplan 21 could, over time, have a shortened setting time, however this will not affect its performance in service. Manufactured in compliance with the regulations of the 2003/53/EC Directive.
