VURA FasTone S2 is a highly deformable adhesive mortar with a deformation of more than 5 mm (class S2) for the highly load bearing, cavity-free installation of 

- Vitrified tiles and slabs as well as porcelain stoneware and Cotto
- Cast concrete slabs
- Natural stones with a low tendency to discolor
- Glass tiles, glass mosaics and mosaics
- VURA FasTone S2 is suitable for indoors and outdoors using the thin- bed or medium-bed method.
Especially useful for the reliable installation of large tiles and slabs thanks to the very high adhesive tensile strength and the stress-absorbing properties. Also, for use on thin slabs made of porcelain stoneware with or without fiberglass mesh on the back.
VURA FasTone S2 ensures a highly flexible adhesive bed and prevents shear stresses, especially on difficult substrates.
For indoor and outdoor use, e.g. on
- Heated screeds and panel heating systems, cellular concrete, dry screeds, balconies, terraces and facades, especially on green precast concrete units (minimum age 2 months)
- Tile backer boards

SUBSTRATE PREPARATION
VURA FasTone S2 adheres to all sound, load-bearing, clean, dry and damp substrates free of substances which may impair adhesion. Remove coatings of insufficient bearing strength.
Indoor use:
Use SuPrima to prime calcium sulphate screeds (gypsum/anhydrite screeds, mechanically roughened and freed from dust, residual moisture: ≤0.5 %, heated screeds ≤0.3 %), cellular concrete and other absorbent substrates.
Prime the non absorbent substrates, tiles, natural stone floors and firmly adhering coatings.
Outdoor and indoor use:
Plasters of mortar groups P II and P Ill (at least 14 days old), cement screeds (at least 28 days old, residual moisture < 2 %, heated screeds < 1 .8 %) and in-situ concrete (at least 28 days old) can be directly covered with tiles / stones.

APPLICATION
Mix VURA FasTone S2 with clean, clear water and stir until the mixture is completely free of lumps. Leave the mortar to mature for approx. 5 minutes and then stir again. If necessary, add small amounts of water until the desired consistency is reached.
Apply FasTone S2 according to the generally recognized rules of the thin-bed resp. mediumbed method or use the buttering-floating method. Allow for a skin formation time of approx. 40 minutes.
Use a trowel with a suitable notch size to ensure cavity free placement of the tiles and slabs.
After the pot life has expired and the mortar begun to set, do not attempt to re-temper the mortar by adding water and stirring again.
