The Mapestone system has been developed to provide durable paving installations capable of withstanding demanding environmental conditions.

The system is designed to resist freeze–thaw cycles, temperature variations, heavy rainfall and exposure to aggressive environments such as de-icing salts, acids and marine spray.

It is suitable for exposure classes XF4 (high water saturation with de-icing agents or seawater) and XS3 (tidal, splash and spray zones).

Mapestone TFB 60 is used to make installation screeds for natural stone architectural flooring suitable for public areas, roads, pavements, parking lots, pedestrian crossings, roundabouts and speed humps.

Mapestone TFB 60 is suitable for installing:

• small blocks; 
• smolleri bricks; 
• cobblestones; 
• slabs; 
• blocks; 
• precast elements;
• self-locking blocks.

• Only apply Mapestone TFB 60 if the temperature of the surrounding air, the substrate and the stone is between +5°C and +30°C.
• If Mapestone TFB 60 is applied when the temperature is between +25°C and +30°C, workability and hardening times are lower.
• Mix Mapestone TFB 60 with the amount of water required for the type of stone to be laid.
• For installation layers thicker than 7cm, it is necessary to add 4-8 mm sized gravel (20-25%) in order to give structure to the screed and to allow a proper hydration during the wetting/tamping process.
• Tamp the surface before Mapestone TFB 60 starts to set to prevent compromising the mechanical characteristics and durability of the flooring.
• Grout the stone with Mapestone PFS 2 VISCO pre-blended mortar to guarantee durability of the flooring.
• We recommend including expansion joints, where possible, along kerbs, pavements, around manholes and drains, along the lines of changes in slope and along rainwater run-off troughs. A maximum pitch area of 30 m² is recommended, according to the norm UNI 11714-1.
