GROVE® MASSETTO

Ready-to- use Screed for Changing Slope
CE Marked in compliance with EN 13813,
class CT-C20-F6 

Description

GROVE MASSETTO is a premixed powder which with the addition of the exact amount of water becomes a slurry specifically designed to modify slopes on flat roofs, terraces and balconies, prior to the application of the liquid waterproofing membrane.

Admixed with GROVE PRIMER it becomes a grout characterized by a high adhesion capacity that allows it to be used on both traditional substrates (cement) and glossy  tiles.

GROVE MASSETTO  is CE marked in compliance with the European Standard EN 13813 and it is classed as CT-C20-F6-A1fl.

Usage field

Special attention must be given during the cast preparation phase, for what concerns both the handling of the product while still in the dry and the mixture. Be careful to use the correct amount of water for the mix, so the ready to use product can retain its easy laying features: keep to the recommended doses.

GROVE MASSETTO is used to:

  • either modify slopes or add thin layers(less than 2 cm thick) to old and new floors, after treating the surface with an adhesive grout made ​​with GROVE PRIMER (1 part by weight) and GROVE MASSETTO (2-3 parts by weight, depending on the desired fluidity and substrate absorption) (Fig. 1);
  • to fill the "open pore" treated screeds by applying a skim coat obtained mixing GROVE MASSETTO with 30% by weight of GROVE PRIMER;
  • to smooth sand and cement screeds with a mixture of GROVE MASSETTO and water to be applied to the substrate when still wet or just set using a mechanical disc.

Advantages

GROVE MASSETTO:

  • is ready –to-use;
  • can be applied in thicknesses ranging from 1 mm to several centimetres to all types of substrates;
  • exhibits very low shrinkage.

Application

Special attention must be given during the cast preparation phase, for what concerns both the handling of the product while still in the dry and the mixture. Be careful to use the correct amount of water for the mix, so the ready to use product can retain its easy laying features: keep to the recommended doses.

Product preparation

Pour the necessary amount of GROVE MASSETTO into a screed mixer (or a mixer for small amounts of mortar) and add water while mixing until you get a WET SOIL consistency.

Product application

Remove from the mixer and lay the material, level and smooth: you can do it straight away by hand, with a steel float, or mechanically when the product starts to set, using a steel disc mono-brush.

Tool cleaning

If the product is still fresh, remove it with just clear water, if it has hardened remove it by mechanical means.
