Technical Information
Product Description

GIUNTOLASTIC is an extremely elastic water based polymer. It is designed to be mixed with cementitious grout (NEOFIL COLOR or FUGACOLOR) in total or in partial replacement to water. The mixture of GIUNTOLASTIC with tile grout powder improves the compactness, abrasion resistance, impermeability and adhesion of grout when applied in joints between tiles.

In addition, the elastic property of the product allows the grout to absorb certain deformation and vibration on the substrates.

  • Improve adhesion to substrates
  • Improve deformability and impermeability of the grout after complete curing
Compiliance Standard
  • European EN 13888-CG2
  • ANSI A 118.6 -1999
Packaging, Coverage / Consumption


GIUNTOLASTIC is available in 20 Liter plastic pails.

Application Information
Instructions for use

Surface preparation

The joints between tiles should be clean free of dust. Clean the joints between tiles and brush before grouting.


Shake GIUNTOLASTIC pail before use. Pour a part of the latex as needed into a clean container and then add NEOFIL COLOR 0-4, NEOFIL COLOR 4-20 or FUGACOLOR. Mix to get a homogeneous paste free from lumps.


Leave the mixture for about 10 minutes, then remix shortly and apply with a rubber grout float into the previously cleaned and wet joints.

Let the product set for about 20 minutes, and then proceed with cleaning the tiles with soft sponge. After the complete hardening of the grout, remove, with a dry sponge, all the remaining traces of grout on the surface. If the surface is still dirty clean it with PULINET. Read the instruction of PULINET in the technical data sheet before application.


Tools and equipment should be cleaned with water immediately after use.

NEOFIL COLOR mixed with GIUNTOLASTIC would perform as follows:
