Properties / Benefits
GOODGEL MAS MORTAR GRADE provides the following benefits:
● Supply excellent lubricity
● Increase pumpability of wet mortar
● Improve workability and open time
● Control bleeding. Suspensions that tend to settle are easily redispersed.

Application
GOODGEL MAS MORTAR GRADE may be used in a variety of cement based, gypsum based and lime based building drymixed mortars as follows:
● Ceramic tile adhesive & tile grouts
● Skim coat with medium pH or high pH
● All pasty mortar system 
● All kinds grouts, masonry mortar
● Autoclaved aerated concrete (ACC)
● Gypsum based mortars
● Pump or machinery mortar

Dosage and Handling
GOODGEL MAS MORTAR GRADE is added to other powdery components and mix to get a homogenous formulation. It can be also made preparation of dispersions before use.
The dosage may vary from 0.05%~1% of the total dry material by weight. The actual required dosage should be evaluated in suitable tests prior to final application.

Storage
GOODGEL MAS MORTAR GRADE may be stored in sealed bags under dry cool place for at least 12 month. Opened packages should be sealed again as soon as possible. Not exposure to water, sunlight, especially during transportation.
