What it does
Hydroxypropyl methylcellulose — the cellulose ether that gives dry-mix mortars and tile adhesives their open time, water retention and workability. The single most price-sensitive line item in a tile-adhesive recipe.
Typical applications
- Tile adhesives (C1 / C2 cementitious)
- Cement-based renders and skim coats
- Self-levelling underlayments
- EIFS / ETICS base coats
- Gypsum-based jointing compounds
