MetalGrade Express is a two component, solvent free, fast curing,
synthetic metal repair compound. Areas of application Sealing of leaks
in pipes, tanks, radiators, ducts 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 Express must be coated with a release agent.
2. Mixing
Only sufficient product which can be applied within the usable life should
be mixed. Mix Base and Activator from the
respective jars onto a clean mixing surface in the ratio indicated. Lids
should be replaced immediately after use. The two components should then

onto the prepared area, working the material into any cracks and surface

and the MetalGrade Express is set. Any leaking fluid must be wiped
from the prepared surface before undertaking the repair.
