Hi-Temp Lab-metal must be stirred thoroughly before use. No additive is needed; the repair compound hardens upon exposure to air. Hi-Temp Lab-metal is a viscous but easily spreadable paste. Upon opening the can, if the Hi-Temp Lab-metal appears stiff, stir in a capful or two of Lab-solvent to restore the product to its appropriate consistency. For any application, the surface must be clean and dry; free of paint, oil, dirt, and any extraneous materials. Roughening the surface provides superior adhesion. Hi-Temp Lab-metal's shelf life is one year in factory-sealed cans. Store in a cool place. See warning label on can.
Hi-Temp Lab-metal may be applied with a putty knife, spatula, trowel, caulking gun, or rubber squeegee. When filling deep holes or cavities, the putty should be applied in thin layers, less than 6mm thick. Allow each layer to dry for at least 24 hours. Dry time may be accelerated with force curing, infrared lamps. This depends on air temp, type of metal.
To apply Hi-Temp Lab-metal with a paint brush, it must be thinned to paint consistency with Lab-solvent, then applied with light brush strokes; not worked over as with paint. Dipping the brush into Lab-solvent periodically will keep the bristles free and prevent clogging.
Depth of application determines drying time; hardening occurs as the dilutent evaporates. The application must air dry for at least 24 hours, or until the product has hardened to a metal state.
In order for Hi-Temp Lab-metal to completely harden after a 24 hour air dry time, it must be exposed to a minimum temperature of 218ºC for a period of at least one hour depending on thickness of application. (The curing process may be achieved by a more gradual "heat-up", as in the repair of an industrial oven or exhaust. In this case, as the oven is heating, the Hi-Temp Lab-metal repair is curing.)
