Plistix 900 F Mixing and Air Setting Instructions
The following is given in good faith for Guidance only.
**Before attempting to mix refractory, be sure to wear proper personal protective equipment such as eye protection, appropriate dust mask, and disposable gloves. Mix outdoors or in a well ventilated area. When mixing add water to the refractory, and stir slowly as not to generate dust plume.
Place dry material into a waterproof disposable container. Add a very small amount of water to the dry material and mix throughly, Repeat this until you've reached a sour cream like consistency, but not runny.
**If applying Plistix over a castable refractory coating, be sure to follow that materials air cure and dry out/ bake out procedure prior to applying Plistix over it. Using a disposable paint brush, dip into mixed Plistix and paint it onto surface to be coated.
** If applying Plistix directly to ceramic fiber blanket, be sure the blanket has been rigidized and dryout procedure has been followed prior to applying Plistix over it. Using a disposable paint brush, dip into the Mixed Plistix and apply to surface using dabbing type motion.
Air Setting Instructions
Once Plistix has been applied, cover forge with a sheet of plastic and allow it to air dry slowly to a hard set. Plistix is an air setting refractory so there is no complicated bake out procedure to follow, but care does need to be taken to ensure the material doesnt dry out too quickly. Do not attempt to speed up the procedure using heat. Air setting is best done at ambient temps not lower than 60°f.
Once material has air dryed to a hard set your forge is ready to use, however the intial firings should be done beginning with a low flame allowing the refractory to warm up slowly to avoid thermal shock failure/damage.
