Step 1

The tile laying sub-layer must be flat, free from brittle and foreign bodies such as for example plaster residue, paint, oils, etc. It must be stable and free from shrinkage and distortion forces and further more it should not be subject to vibrations. The absorbent sub-layers are primed using GLX 290 primer before application.

Step 2

In a clean container add 8.5-9.0 liters of clean water and gradually empty the content of a 25 Kg sack of product VKW 127, mixing continuously with an electric mixer in order to acquire a uniform slurry mass.

Step 3

Let the resulting mixture age for 5 minutes and mix again.

Step 4

The mixture is ready to be used within the next 4 hours.

Step 5

Following the preparation of the mixture do not add more water in order to correct the workability of the slurry. This would lead to the reduction of its tolerances and the increase of its shrinkage.

Step 6

Spread the adhesive on the surface and then comb the adhesive layer using a special toothed spatula.

Step 7

Within 30 min since adhesive layering, place the tiles at their location, pressuring firmly in order to ensure full contact.

Step 8

The installation of tiles on the wall may be performed starting from the upper part with the entire tile and without any slippage.

Step 9

The excess adhesive must be cleaned off the joints prior to its drying. On surfaces larger than 25m₂ it is necessary to install expansion joints. At the areas of contact of floors with walls it is recommended to use adequate silica-containing pastes. During application and for the next 24 hours the environmental and sub-layer temperature must be between +5_oC and +35_oC. The adhesive is cleaned with water while still wet. When it hardens it is removed mechanically.
