For maximum bonding, prepare areas to be repaired by grit blasting, machining or abrading.
Clean with M-51 Cleaner Conditioner. Be sure areas being bonded are dry and free from
moisture. Bonding and hardening are enhanced when metal surfaces are above 75F, In cold
environments, heat parts with a flame, heat lamp or forced hot air. Be sure flame sources do not
leave carbon or other deposits.
thoroughly until a smooth, lump-free consistency is achieved. Completed mix should be an even
color, without streaks.
Small quantities (1 unit or less) are easily mixed by hand for 2 to 5 minutes. Large quantities
should be mixed with a power paddle. A large mass will cure faster and working time is reduced.
When ambient temperature or temperature of surface is below 60F, compounds will not
achieve full strength. Low temperatures may inhibit hardening. Heat deposit and part being
repaired with indirect heat (lamp or warm air) to room temperature. In general, deposits harden
faster when parts and deposit are heated. CAUTION: DO NOT EXPOSE DEPOSITS
DIRECTLY TO FLAME.
