About ST2 Gold
Vitrified and ceramic tiles, floors and walls alike
A step up in bonding strength for general tiling work. ST2 Gold holds firm across a wider range of tile sizes on floors and walls, with tested slip resistance for vertical fixing.
Ideal applications
- Vitrified and ceramic tiles
- Floor and wall tiling
- Kitchens, bathrooms and living areas (internal)
- A wider range of tile sizes than ST1
Key features
- Non-slip grip. Holds tiles in place on application, so they don't creep or slide before the bond sets.
- Crack resistant. Formulated to keep tiles from cracking as the surface settles over time.
- No hollow sound. A solid, even bed underneath. No hollow patches, no weak spots.
- Floor & wall. One adhesive family for internal floor and wall tiling.

How to use
Six steps, printed on every bag
1
Clean the surface
The base must be firm, level and free of dust, oil, paint and loose material. Dampen very dry, absorbent surfaces and wipe away standing water.
2
Measure the water
For ST2 Gold: 260 ml per kg, about 5.2 litres per 20 kg bag.
3
Pour the adhesive
Add the powder to the water, not the other way round, while mixing.
4
Wait
Let the mix stand for about 5 minutes so the additives activate.
5
Stir
Re-mix to a smooth, lump-free paste, ideally with a drill and paddle at low speed. Do not add more water later.
6
Apply
Spread with a notched trowel, comb in straight lines, place the tile and press with a slight twist. Adjust within the adjustment time and grout after 24 hours.
