Once hardened, ARDEX G7 FLEX has water- and dirt-repellent properties that have a positive influence on the appearance, consistency and preservation of the coatings.

The high degree of flexibility and high adhesion lead to a reduction of stresses when it comes to surfaces exposed to thermal loads outdoors and on underfloor heating and make an essential contribution to the safety of the coatings.

Product description:

Powder based on fast-setting cements, filler material as well as additives with flexibilizing effects.

Kneaded with water originates a flexible, creamy mortar, easily workable and long cleaning time.

Instructions for use:

Pour clear water into a mixing container and mix ARDEX G7 FLEX until a lump-free, homogeneous, pasty mortar is obtained.

Mixing ratio:

12.5 kg ARDEX G7 FLEX: approx. 2.4 liters of water.

The joint mortar is usable for about 45 minutes (at 20°C). Higher temperatures reduce the working time and lower temperatures extend the working time.

Using a rubber trowel, it is easy to introduce the mortar into the joints. In the same working process, deeper joints can also be filled without leaving voids. On floor surfaces, the mortar can be introduced by means of a rubber trowel.

Once the joint mortar is dry, the grouted surfaces can be cleaned with a damp sponge or a trowel with a scouring pad. If the grout has been deposited and dried on the tiles, the surface is first rinsed with water and a sponge and then thoroughly washed until clean. The residual mortar veils, which are only visible after drying, are then removed with a sponge.

ARDEX G7 FLEX joint paste should not be used at temperatures above 5°C and below +30°C.

In case of doubt carry out a preliminary test.


When grouting porous or matt enameled parts, mortar residues may stick. It is essential to make tests on these tiles.

In case of treatment with acids, wash the joints before. The use of acids should be avoided since their use can cause discolorations, it is recommended to use neutral or slightly alkaline detergents.

The humidity of the support and the different capacity of absorption of the edges of the pieces can bring as consequence a variation of color in the joints.

In spas and swimming pools it is advisable to apply ARDEX WA or ARDEX EG8, joint mortars with epoxy resin, resistant to chemical attacks and aggressive cleaning.

For interior marble joints, ARDEX MG, which prevents discoloration, is recommended. 

Despite preventive protection against mold and mildew, regular cleaning and maintenance of the joints cannot be dispensed with.
