General Mixing instructions –
-Your mixing container and equipment should be clean and free of all previous plaster mixing debris. Old plaster will cause your new mix to set irregularly and at a faster rate.
Water needs to be carefully and specifically measured. Water temperature is very important to your set time. Testing water is at 70°F – use a thermometer! Hotter water will speed up your set time, cooler water will slow and retard the set time.
-Plaster mixes into water: sift your plaster into the pre-measured water, allow to slake for 30 seconds and mix time will be about 30 – 60 seconds. Plaster ages, it is hydroscopic. Older plaster may require less water.
For USG1:
• Mix should be 1 part water to 1½ parts plaster (or 35 lbs water to 50 lbs plaster)
• Slowly add plaster in water.
• Allow to soak for 2 minutes.
• Mix 2 minutes to heavy creme density.
