Cellulose ether

HPMC

Hydroxypropyl Methyl Cellulose

A cellulose ether used across tile adhesives, renders, plasters and self-levelling compounds. Grades differ mainly by viscosity, which controls water retention, sag resistance and workability in the wet mix.

Formulation

Application and dosage

Dosage is expressed as a percentage of dry mix weight. Values are starting points and should be confirmed with trial batches using local raw materials.

Cement tile adhesive

0.25 – 0.40%

Adjust for open time and slip resistance

Wall putty

0.30 – 0.50%

Higher dose for sand-rich fillers

Gypsum plaster

0.20 – 0.40%

Balance workability against setting time

Self-levelling compound

0.05 – 0.15%

Combine with a superplasticiser as needed
