ATLAS ATUT - adhesive for tiles (C1T type)

Classification of adhesives for tiles

Adhesives for tiles are classified and marked according to PN-EN 12004 Standard

The Standard specifies three types of adhesives:

C – cement based adhesives

D – dispersion adhesives

R – adhesives based on reactive resins

Each of the above types of adhesives can appear in different forms (classes) corresponding to additional requirements:

1 – standard setting adhesives – adhesion after 28 days ≥ 0.5 N/mm2

2 – adhesives of improved parameters – increased adhesion, after 28 days ≥ 1.0 N/mm2

F – fast setting adhesives – adhesion ≥ 0.5 N/mm2, measured after time not exceeding 6 hours

T – adhesives with reduced slip – slip not exceeding 0.5 mm

E – adhesives with extended open time – adhesion after 28 days ≥ 0.5 N/mm2, despite the fact the time between the application of the adhesive and placing a tile is not shorter than 30 minutes.

Adhesive selection

Before fixing ceramic tiling or natural stone, please pay attention to a few elements significant for the proper selection of the adhesive.

These are:

• substrate – the material it is made of, its absorptive power, roughness, adhesiveness, cleanliness, maturing degree and possible deflection
• tiles – their kind (gres-porcelain, terracotta, glazed tiles, stone), size (mosaic, large size), absorptive power and resistance to discolouration
• conditions of use of the tiling – the atmospheric influence (indoor, outdoor), situation (wall or floor), kind and volume of usable load (pedestrian or vehicle traffic), frequency and the volume of temperature changes.
