Descripción sistema
The use of large-format ceramic tiles in flooringis becoming increasingly common. The special characteristics of this type of tile, such as a size greater than 2000 cm², low water absorption and often having a curvature or warping characteristic of manufacture, make it necessary to lay them using the double gluing technique, which consists of spreading the material with a notched trowel on the substrate and then applying a layer of adhesive on the back of the tile.
An alternative technical solution is to usePAM® ECOGEL FLEX in its fluid consistency, i.e. the double consistency of this product allows it to ensure optimum adhesion in a fluid form without the need for double gluing.

PREPARATION OF THE SUBSTRATE

Check that the substrate is resistant, perfectly set, free of dust, paint, oil…

Check the flatness of the substrate with a ruler 2 metres long; differences should be less than 5 mm. In case of ceramic sheet the differences shall be less than 3 mm.
APPLICATION

Knead with a slow electric mixer (500 rpm), leave to stand for 2 minutes and spread PAM® ECOGEL FLEX in a fluid consistency on the substrate with a semi-circular notched trowel, without double gluing.

Although this product has a long open time, check that the adhesive has not formed a surface film that prevents adhesion, especially in hot or windy conditions. If this is the case, re-comb with the aid of a notched trowel.

Press the tiles in order to achieve a correct solidification of all the pieces, thus avoiding the existence of gaps between the tile and the substrate.

Leave a minimum joint width of 2 mm in interiors and 5 mm in exteriors; grout after 8 hours with the BORADA® range of mortars for joints by Molins.
Recommendations
- Do not apply in rainy conditions, or at temperatures < 5ºC or >30ºC.
- On poorly absorbent substrates, open the pore with water and 50% hydrochloric acid (salfuman).
- In case of significant flatness defects, PAM® ECOGEL FLEX or PAM® ECOGEL SUPERFLEX can be applied in a thixotropic consistency up to 10 mm in thickness and a thin layer printed on the surface of the workpiece (double gluing method).
- Carry out an adequate treatment of movement joints, respecting structural joints, perimeter joints (in spaces larger than 7 m²) and intermediate joints (in interiors every 40 m² and in exteriors every 16 m²).
