MetalGrade Rebuild is a dual component, solvent free, synthetic
metal repair compound. Areas of application : Worn or damaged
shafts, oversized bearing housing, cracked casings, distorted flange
faces, cracked engine blocks, sloppy keyways, scored hydraulic rams etc.
1. Surface preparation
Heavy contamination due to oil or grease must be removed using a
cleaner. Where possible, abrasive blasting is the preferred surface
preparation, especially in fluid flow repairs.
A Remove all contamination oil, grease and dirt with a cleaner.
B Remove all loose rust and surface coatings.
C Roughen the surface, preferably with abrasive blasting. Alternatively
a die grinder, needle scalar or angle grinder may be used. If grinding make
sure the surface is roughened, not polished. Where grinding or needle
gunning is used, the surface should be cross scored to improve adhesion.
D To ensure that all contamination is removed carry out a final degreasing
with a cleaner. Cloths should be frequently changed to avoid
spreading contamination. On deeply pitted surfaces of porous castings,
a cleaner should be worked into the surface by brush and washed off
using excess cleaner.
E Parts for example, threads or bearing surfaces which must
remain in position during application but which should not adhere to
MetalGrade Rebuild must be coated with a release agent.
2. Mixing

3. Application
Prepared surfaces should be dry. Using the Spatula provided, the mixed
material should be pressed firmly onto the prepared area, working the
material into any cracks and surface defect.
If Reinforcement Bandage is used to strengthen the repair, the
bandage should be impregnated with MetalGrade Rebuild, or the bandage
should be laid over the surface of the MetalGrade Rebuild and pressed into
the surface. Additional MetalGrade Rebuild should then be applied over
the surface.
Once the MetalGrade Rebuild has reached initial set the material can be
separated from surfaces treated with release agent.
When MetalGrade Rebuild is being used to repair leaking pipes, the
flow through the pipe should be discontinued until the repair is made
and the MetalGrade Rebuild is set. Any leaking fluid must be wiped
from the prepared surface before undertaking the repair.
