Mapei Mapecem Pronto is a pre-blended, ready-to-use, quick-setting and drying (24 hours), controlled-shrinkage mortar for screeds.

  • For professional use only
  • For use with screeds ready for foot traffic after 2-3 hours, and dry after 24 hours
  • Screeds on which it is possible to lay ceramic tiles after 3-4 hours
  • Screeds on which it is possible to lay PVC, linoleum, wood and natural and artificial stone materials after only 24 hours (residual moisture lower than 2%)
  • Repairs and renovation of screeds in areas subject to continuous traffic (e.g. supermarkets, hospitals, airports, etc)
  • Screeds incorporating heating systems, without adding plasticisers
  • Used for internal and external floating and bonded screeds on old and new floor slabs, for laying wood, PVC, linoleum, carpet, ceramic, natural stone and any other type of floor covering where quick drying is required for immediate laying of the floor covering
  • Complies with the conditions of Annex XVII to Regulation (EC) N° 1907/2006 (REACH), item 47

Features & Benefits


  • Uses:
    • Screeds ready for foot traffic after 2-3 hours, and dry after 24 hours
    • Screeds on which it is possible to lay ceramic tiles after 3-4 hours
    • Screeds on which it is possible to lay PVC, linoleum, wood and natural and artificial stone materials after only 24 hours (residual moisture lower than 2%)
    • Repairs and renovation of screeds in areas subject to continuous traffic (e.g. supermarkets, hospitals, airports, etc.)
    • Screeds incorporating heating systems, without adding plasticizers
  • Pre-blended, ready-to-use, quick-setting and drying, controlled-shrinkage mortar with a special hydraulic binder base, admixtures and selected aggregates to be mixed with water
  • Extremely easy to use, in that it is simply mixed with water. This means that human error due to incorrect dosage of the binder and choice of aggregates is avoided, which could compromise the final characteristics of the screed once it has set
  • Ideal solution where finding good quality inert material of the correct grade is difficult, or in the case of installations in areas, such as historical town centres, where transportation and preparation of the blend with traditional binders becomes problematic



Preparation


  • All types of substrate are suitable for installing screeds made using Mapecem Pronto
  • In those cases where quick drying is required, if there is moisture present in the substrate, screeds made using Mapecem Pronto must be isolated with a suitable vapour barrier, and must be at least 35 mm thick for floor coverings subject to foot traffic
  • For screeds bonded to the substrate (thicknesses lower than 35 mm), check beforehand that they are dry and free of cracks, powder, loose parts, paint, wax, oil and traces of grease
  • Mapecem Pronto mix may be prepared with one of the following:
    • Paddle mixer
    • Drum mixer
    • Forced action mixer
  • Mix a 25 kg bag of Mapecem Pronto with 2.1-2.3 L of water for 3-4 minutes. The amount of water must not be modified for any reason, otherwise the final performance characteristics will be compromised
  • Tamp and float the mix until a smooth, closed, surface without residual water is obtained
  • Each mix must be poured and tamped as quickly as possible, and after no more than 30 minutes from the start of preparation
  • The surrounding temperature influences the setting and drying times of screeds made using Mapecem Pronto.



Application


Floating Screeds (thickness from 35 to 60 mm)

  • Mapecem Pronto mix must be laid on an isolating layer made up of polythene sheets or a similar material in order to allow for movement between the screed and the existing substrate
  • In case of rising damp, the aforementioned isolating layer must be formed using a sufficiently waterproof membrane to form an efficient vapour barrier
  • The areas of the Mapecem Pronto screed which have pipe-work running through them must be reinforced by positioning light, metallic reinforcement (e.g. electro-welded hexagonal mesh)
  • The laying of screeds made by Mapecem Pronto is carried out using the same technique as for cementitious screeds. Prepare a series of level guides, spread the mix and tamp thoroughly before finishing off with a float, to obtain a better surface finish
  • Around the perimeter of the room and around columns which run through the floor, it is good practice to place 1 cmthick isolating material (such as polystyrene, cork, etc.) before casting
  • If work is interrupted, cut the screed perpendicularly to the substrate and insert a series of 3-6 mm diameter, 20-30 cm long steel rods in the screed at a pitch of 20-30cm
  • This operation will guarantee a good weld between the construction joints, and avoid cracking and uneven joints

Bonded Screeds (thickness up to 40 mm)

  • Screeds with a lower thickness must be bonded to the substrate, which may be either a cementitious type or made up of existing flooring in ceramic or stone material
  • Once the substrate has been prepared sufficiently, and immediately before spreading on the Mapecem Pronto mix, prepare bonding slurry with Planicrete according to the ratio in the table below
  • Apply a continuous, even 2-3 mm layer using a large flat brush, a scrubbing brush or a trowel
  • To get perfect adhesion, spread Mapecem Pronto on the slurry while it is still fresh (fresh on fresh technique). If the floor is subjected to high mechanical stresses, the construction joint must be made by replacing the Planicrete cementitious bonding slurry with Eporip
  • Spread on the Mapecem Pronto using the same method described above

Cleaning & Consumption

  • Tools may be cleaned using water
  • The consumption of Mapecem Pronto is approximately 20kg/m² per cm of thickness, according to how much tamping is carried out



Limitations


  • Do not use Mapecem Pronto on screeds subject to rising damp (lay a vapour barrier)
  • Do not mix Mapecem Pronto with other binders (e.g. Mapecem, Topcem, cement, lime, gypsum, etc.) or aggregates
  • Mix Mapecem Pronto with the correct amount of water
  • Do not add water and do not re-mix mortar prepared using Mapecem Pronto if it has already started to set
  • Do not wet the surface of screeds made using Mapecem Pronto
  • Do not mix in cement plants or transport the product in cement trucks: the setting time of Mapecem Pronto is too short
