Kaolite® 1:2:4 Monolithic Product Data Sheet Product Description Kaolite 1:2:4 is a general-purpose, cast/gun lightweight monolithic for use up to 2000°F (1093°C). It provides the advantage of a pre-mixed, controlled formula product compared to typical 1:2:4 spec field mixes. Instructions for using Casting: Highest strength is obtained with a monolithic refractory by using the least amount of clean mixing water that will allow thorough working of material into place by vibration. A mechanical mixer is required for proper placement (paddle type mortar mixers are best suited). Mix for 4-6 minutes to achieve a ball-in-hand consistency. Place material within 30 minutes after mixing. Gunning: Use suitable gunite equipment. Material should be pre-dampened uniformly with approximately 8-12% by weight of clean water in a mechanical mixer before placing into gun. This will reduce rebound and dust. Add required water at nozzle with needle valve controls for effective placement. Suggested air pressure at the nozzle is 1.4 to 2.1 bar (20 to 30 psi). Precautions: Watertight forms must be used when placing material. All porous surfaces that will come in contact with the material must be waterproofed with a suitable coating or membrane. For maximum strength, cure 24 hours under damp conditions before initial heat-up. Keep freshly placed monolithic warm during cold weather, ideally between 16°C and 27° C (60°F and 80°F) until wet curing is completed. New monolithic installations must be heated slowly the first time. Freshly placed lightweight monolithics are sometimes prone to a deteriorating condition called alkali hydrolysis when they are kept in a non-dried state for a sustained period of time. Under these conditions, the monolithics should be force dried Bond type Maximum grain size, mm Maximum service temperature, °C (°F) Water addition, % by weight casting by vibrating Packaging in bags, kg (lbs) Whilst the values and application information in this datasheet are typical, they are given for guidance only.
