WHO WE ARE

Eazymix Ltd. develop and manufacture chemical additives for gypsum plaster.  Eazymix was established by a trade plasterer with a mission to make plastering projects more efficient and cost effective.  Eazymix's products tailor the setting profile of finishing plasters for specific needs; speeding it up for small jobs and slowing it down for larger, trickier areas.  The products have been approved by trade associations, trade press and more importantly trade plasterers. See below for details on specific products.

GYPSUM PLASTER SETTING TIMES

Gypsum plaster is derived from gypsum rock that is mined or quarried, crushed and ground into a fine powder.  The powder is calcined by heating it to approximately 175 degrees C, driving off approximately three quarters of the chemically combined water. The calcined gypsum, or hemihydrate, becomes the base for gypsum plaster, gypsum board and other gypsum products.

Gypsum plaster contains between 70% - 95% gypsum stone, it can also include impurities such as clays, limestone and sedimentary rocks as well as plaster modifiers added by the manufacturer.

Once supersaturated with water gypsum plaster forms a slurry that can be spread evenly over a substrate.

Gypsum plasters set and harden primarily through a dissolution and recrystallisation process.  The plaster dissolves (hydrates) to form calcium sulphate dihydrate, followed by the growth of interlocking rod-like crystals.  

Most finishing plasters are designed and manufactured to set within approximately 2 hours of being hydrated.  This is acceptable for the majority of plastering projects, however some projects require a set that is either quicker or slower.  Additives to the water used in the plaster mix, such as Extratime and Halftime, alter the hydration and recrystallisation process helping trade plasterers and DIYers to modify the setting profile to suit their project.  Extratime can be added to extend the setting time for very large or tricky areas.  Halftime can be added to speed up the recrystallisation process for small projects where the set needs to be much quicker.
