Product Information

Mapei Mapecem is a special fast-setting cement for the preparation of fast-drying screeds (24 hours) with controlled shrinkage. For the formation of bonded, un-bonded, floating and heated screeds on new or existing substrates for the installation of moisture sensitive flooring or any other type of flooring where fast-drying screeds are required for rapid laying. Mix with graded aggregates and water. Install ceramic tiles after just 3 hours. Install stone materials after just 3 hours. Install resilient and wood materials after only 24 hours.

Key Features:

  • Very Rapid Fast Drying screed binder
  • Replaces cement
  • Ideal for overnight work or very quick floor replacement

Surface Preparation
All substrates are suitable for receiving a Mapecem screed as long as they are not subject to rising damp, in which case install a suitable waterproof membrane for non floating screeds (from 10 to 35mm) which have therefore to be anchored. The substrates must be dry free from cracks resistant to compressive and tensile strength free from dust, loose materials, paints, wax, oil, traces of gypsum.

Recommended Systems
Floating screeds from 35 to 60mm. Preparing the mix. Mapecem must be mixed carefully and quickly, with water and graded aggregates 0/8 designation for a maximum of 3-4 minutes, in a forced action type mixer. The mix must be spread and leveled in the shortest time possible and not more than 30 minutes after mixing. Special care must be taken with the quantity of water that must be enough to form a cohesive mass so that tamping gives a flat surface without a cement film. Mapecem, aggregates and water can be mixed: in a paddle mixer; in an ordinary concrete pan mixer; in a screw mixer; In a pressure pump. The Mapecem mix can be placed using an automatic pressure pump. In any case it is absolutely necessary to strictly follow the instructions regarding the dosage and mixing time. Spreading the mix. The Mapecem mix is placed onto a substrate like any ordinary concrete. A polyethylene sheet must be laid (even over a bituminous membrane or other existing waterproofing substrate) in order to create an easily flowing layer between the Mapecem screed and the already existing substrate and at the same time to prevent any rising damp.
