SpECbuild Primer E1 may be applied onto clean,
sound substrates to promote a high strength bond
to cementitious materials such as in the following
situations:
· Concrete repair applications
· Bonding of floor screeds
· Bonding newly poured concrete to existing
concrete
· High mechanical strength
· Produces a bond that exceeds the cohesive
strength of the concrete
· Provides an impervious barrier to the passage of
chlorides
· Solvent free
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.
SpECbuild Primer E1 is supplied in 1, 2 and 5 litre
units. The theoretical consumption rate is 5 m²/litre.
