Execution of hygienic joints highly resistant to chemical agents

Joints between tiles constitute a natural separation therebetween and are known as tile-to-tile joints.

Tile-to-tile joints fulfill two basic functions:

Technical: Reduce aggressions due to substrate movements and stresses, and improve tile adherence.

Furthermore, they prevent the accumulation of water on the substrate and the appearance of pathologies.

Aesthetics: Their correct application in terms of width, color and execution improves the decorative image of the surface clad with ceramic, stone material or mosaic.

The use of a biocidal preservation system prevents the appearance of molds and other micro-organisms.

Preliminary analysis

We will use reactive resin joints when the rejointing of tiles resistant to chemical and bacteriological attacks, fully waterproof and without any type of retraction is required.

These types of joints are obligatory in very specific areas such as: laboratories, industrial kitchens, chemical and food industries, etc.

Technical considerations

Before grouting, make sure that the ceramic tiles have been placed correctly and that the tiles are perfectly anchored to the substrate.

Joints between tiles should not be less than 1.5 mm in interiors or 5 mm in exteriors.

When grouting, observe the wait time indicated on the Technical Data Sheet of the product used, as possible rising water or damp may form salt deposits on the surface of the tile-to-tile joint or changes in colour, spoiling the desired aesthetic effect. 

Joints must be clean of dust, friable parts and adhesive residue to obtain maximum adherence.

Mix the two G#color Junta epoxi components in their entirety using a slow electric mixer until a smooth, homogeneous paste is obtained.

Once the paste has been applied using a rubber trowel, remove any excess product using a clean, damp cellulose sponge, rinsing it frequently with hot water.
