Applications
Floor and wall tilesLarge-format tiles and stoneTile on tileBoards, plywood and MIVAN wallsSwimming pools
Procedure
- Prepare a sound, clean, level surface free of oil, laitance and curing compound.
- Tile on concrete at least 28 days old, unless TILEX URP ADMIX 73 replaces the water in TILEX 351 PLUS.
- Dampen the surface; no standing water.
- Put water in the bucket first and add the powder: TILEX 351 PLUS takes 5.5 to 6 litres per 20 kg bag. Mix, stand 5 minutes, mix again.
- Comb the bed with a 6 mm × 6 mm notched trowel; spread only what can be tiled in the 30-minute open time.
- Press each tile in with a twist and bed with a rubber mallet. Back-butter tiles larger than 12 × 12 inches.
- Use spacers and leave movement joints, sealed, never grouted.
Important Suggestions
Why This Treatment?
A thin, full-contact polymer-modified bed bonds far better than a thick cement mortar bed, so tiles do not sound hollow or come loose.
