SpECseal Primer 25 is use when preparing porous
surfaces such as concrete, brickwork, stonework,
asbestos and timber and non-porous surfaces such
as stainless steel and ceramics.
Surface preparation
Joint surfaces to be primed must be completely dry
and free from all dirt, dust, cement laitance and
other loose and deleterious matter. This is best
achieved by grit or sand blasting or thorough wire
brushing and then blowing clean with oil free
compressed air prior to the installation of backer
rod or bond breaker tape.
Mixing
SpECseal Primer 25 is a two component primer.
The base and hardener components should be
mixed together for 2 minutes to produce a uniform
consistency.
Application
The primer should be applied to clean, dry surfaces
prior to the installation of backer rod or bond
breaker tape. The freshly mixed SpECseal 625
should be applied after the primer solvent has been
released and when it is just touch dry. The sealant
should be applied ½ – 2½ hours after priming.
If the primer is left to dry longer than 2½ hours the
surfaces must be re-primed prior to applying the
sealant. Allow to become tacky before installing
SpECseal 625.
SpECseal Primer 25 is available in 1 litre
pack.
