METALGRADE EXPRESS

Instructions for use

Before proceeding, please read the following information application carefully to ensure that proper procedures are fully understood. 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.

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 be thoroughly mixed until completely streak free, using the spatula provided.

3. Application

Prepared Surfaces should be dry. Using the Spatula provided the mixed material should be pressed firmly

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.
