WOOL 50 MORTAR to be applied on WOOL 50 CAST concrete safety layers. Its fine grain and narrow grain size distribution ensures a uniform layer.
Used also for jointing and sealing chromic oxide bricks.

Instructions of use
Screed beam (1 m maximum)
5 mm diameter round metal section or 5 mm thick flat metal section
Vibrating table / Vibrating pin
Vacuum pad for gripping tiles
150-liter capacity cement/concrete mixer depending on the size of the work site
Shovels, brooms, trowels
A series of wood studs the same height as the thickness of the desired slab, of standard length
Graduated measuring device
Provide potable water for wetting.
Amount of water to be used (trowel-application): 13 to 15% of weight in water, for temperatures between 5°C and 28°C.
Carefully homogenize the mortar prior to applying. Use a paddle mixer if possible.
Apply the mortar with a trowel, spreading it over a 5mm thickness using a flat beam. To obtain consistent thickness, we recommend using flat or round metal sections, laid on the slab to serve as a guide as you progress.
Spread the mortar over a width which is slightly wider than one row of tiles, and over a length which enables a few tiles to be laid at a time.
Then, carefully lay the tiles on the mortar. You can either reserve space for the expansion joints required for the type of assembly planned, or you can lay the tiles up against each other to obtain a closed joint. Carefully check that the mortar does not rise up between the tiles.
We recommend using a vacuum pad to grip and lay the ZIRCHROM / WOOL tiles.
