EPOXY RESIN BONDING AGENT FOR CEMENTITIOUS MATERIALS

Preparation
It is essential that adequate preparation is carried out prior to the application of SpECbuild Primer E1.
The prepared surface should be free from laitance, dust, algae, oil and grease.

Mixing
SpECbuild Primer E1 is supplied in a two component kit, consisting of a base component and a curing agent.
Both of the components should be briefly stirred to ensure that any settlement products are fully suspended.
The entire contents of the curing agent should be emptied into the base component, ensuring that the sides of the curing agent tin are carefully scraped to remove all the material. The combined materials should then be mixed using a suitable slow-speed drill and mixing paddle for 2 minutes until uniform. The sides of the tin should then be scraped and mixing should continue for a further 2 minutes.

Application
The mixed product may be applied by brush. The theoretical consumption rate is 5 m2/litre.
Where SpECbuild Primer E1 is used as part of the SpECbuild concrete repair system, care should be taken to ensure an unbroken coating. One coat should be applied and allowed to gel. A second coat should then be applied and used to provide the bond.

Where a subsequent repair product is to be applied by spray, then sharp sand may be broadcast into the surface of the second coat of the primer.
