Tile adhesive materials used for the installation of tile /
stone shall be capable holding the installed tile / stone without slip from the
vertical surface. This strength of adhesive is called as slip resistance.
Slip
resistance of the adhesive can be tested as per BS EN 12004 by referring BS EN
1308 as follows:
1. Standard
conditions shall be (23 ± 2) °C and (50 ± 5) % relative humidity and the speed
of air in the testing area less than 0,2 m/s
2. Clean and
dry type V2: dry pressed ceramic tile in accordance with EN 14411, group BI a,
with a water absorption ≤ 0,5 % by mass, unglazed, with plane adhering surface
and with facial dimensions of (100 ± 1) mm x (100 ± 1) mm and mass of (200 ±
10) g.
3. The concrete
slab shall comply with EN 1323
4. A notched
trowel having 6 mm x 6 mm notches at 12 mm centres.
5. A mass capable of
exerting a force of (50 ± 0,1) N with a cross-sectional area of less than
(100 ± 1) mm
x (100 ± 1) mm.
6. A Vernier
calliper accurate to 0,01 mm.
And, other
application tolls.
Place the
concrete slab with all fittings. Mix and apply adhesive, install the tile, measure
the distance with Vernier calliper, after 30 Sec, place the concrete slab in
vertical position. After 20 min, remeasure the distance and find the difference
between the previous average measurement and the now measured one. Express the
difference in mm.
