Step 1

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

Step 2

In a clean container add 4.5-5.0 liters of clean water and gradually empty the content of a 25 Kg sack of product FSW 140, mixing continuously with an electric mixer in order to acquire a uniform grout mass. Let the resulting mixture age for 5 minutes and mix again.

Step 3

The mixture is ready to be used within the next 1.5 hours.

Step 4

ain. The mixture is ready to be used within the next 1.5 hours. 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 5

This would lead to the reduction of its tolerances and the increase of its shrinkage The open time for application is 10min.

Step 6

Following completion of the application clean the surface with a wet sponge.

Step 7

The open time for application is 10min. Any excess adhesive must be removed from the joints.

Step 8

After the lapse of 1-2 hours from the application of the grout on the firebricks, perform mounting using the same product.

Step 9

Prior to the initial usage of the fireplace, oven, etc, the grout must be fully dried. It is recommended that the initial operation is performed after 10 days.

Step 10

During application and for the next 24 hours the environmental and sub-layer temperature must be between +5_oC and +35_oC.

Step 11

The adhesive is cleaned with water while still wet. When it hardens it is removed mechanically.
