SOLVENT-FREE EPOXY LINING AND BENCHING MORTAR

Preparation
The substrate must be thoroughly prepared by either high pressure water jetting or by light grit blasting. Any contaminants such as oil, grease or laitance must be removed completely.

Priming
The prepared surface should be primed with SpECbuild Primer E1.

The contents of the curing agent should be emptied into the base component and stirred with a spatula until the product appears uniform.

The mixed primer should then be applied to the prepared substrate by a stiff brush at 5 m²/litre. If the primer appears to be absorbed into the surface easily, it will be necessary to apply a second coat once the initial coat is tack-free.

Mixing
SpECcoat MHL is supplied in a three-component pack consisting of one tin of resin, one tin of hardener and one bag of specially selected fillers.

The product must be mixed as follows:

Empty the contents of the hardener tin into the base component and mix with a slow speed drill and paddle until uniform.
Empty the mixed resin and hardener into a clean 25 litre steel pail and whilst mixing, slowly add the filler component. The sides of the pail should be scraped down during mixing to ensure that all the ingredients are thoroughly blended. Mixing should continue for at least 5 minutes.

Application
SpECcoat MHL should be applied to the prepared and primed substrate using a steel trowel. The product should be pressed onto the surface in thickness no greater than 12mm vertically and in hot conditions it may be necessary to reduce the build to 10mm to avoid sagging. If subsequent layers are required, finishing of the first layer should be minimal to provide a mechanical key for the subsequent layer, which must be applied 24 hours later. The final layer should be close trowelled to achieve the desired finish.
