3. Fill seal off fitting with plastic porcelain (mixing instructions below).
4. Replace plug in seal off fitting.
MIXING INSTRUCTIONS
Powder is an inorganic, chemical-setting, magnesium oxide base material that is mixed with water as used. Powder
develops minimum expansion while hardening into a porcelain-like body.
Recommended mix ratio is 5 parts powder to 1 part water, by weight. Gradually add powder to warm water while mixing
until consistency is obtained. Mixing may be done with a slow-speed mixer or by hand with a spatula. Minimum amount
of water should be used as excess water reduces mechanical strength and delays set time. Failure of the cement to
adhere indicates setting has begun – discard cement, do not attempt to retemper by adding more water.
Powder hardens with an internal chemical-setting action in 18 – 24 hours at ambient temperature. If it is desired to
accelerate the cure, low temperatures, oven drying at 180°F can be used. Avoid steaming while drying.
Keep powder tightly sealed when not in use.
Caution: Hazardous contents; Silica. Dust may dehydrate mucus membrane. Repeated inhalation of dust may cause
delayed lung injury.
Avoid breathing of powder by wearing respirator. Avoid contact by wearing appropriate gloves, goggles or face shields. If
powder gets into eyes, wash with copious amount of water and consult a physician. Wash hands thoroughly with soap
and water after handling and before eating or smoking.
