APPLICATION
Joint preparation
Joint surfaces must be free from dust, dirt, grease, oil,
rust, old coatings and other contaminants. SpEC R.B.
Seal may be applied to slightly damp surfaces, but
wet or water logged areas must be left to dry. Where
algae and fungi have grown, they must be removed
and the area treated with a fungicide to discourage
further growth. Where a neat finish is required, joint
edges must be masked before priming or sealing.
SpEC R.B. Seal must be supported by a firm joint
filler such as SpECcell Fibre in expansion joints, or
other backing materials in difference applications.
Priming
SpEC R.B. Seal does not require a primer under
normal conditions. However, for resealing jobs and on
old and porous surfaces apply a cost of SpEC Primer
No. 2 - to joint sides and allow to dry before sealing
with SpEC R.B. Seal.
Application
Apply SpEC R. B. Seal to the joint using a trowel,
putty knife or spatula, ensuring joint base and corners
are well filled. Tool the surfaces for a neat finish

and remove surplus material promptly. For horizontal
joints in roots and other exposed areas leave the
sealant
2-3mm
below
the
surface.
Gap Filling: Fill gaps and cracks as described above.
Pointing: Fill pipe entries, pipe joints, corrugated
sheet overlaps, etc as above, and where necessary
form a triangular bead outside the joint.
Bedding: Spread a layer of SpEC R.B. Seal over the
base as required and place the units over the
bedding layer, pressing firmly into place.
SpEC Primer No. 2
Solvent based bituminous primer for old and porous
surfaces. Apply a thin coat by brush to joint sides and
allow to dry before sealing.
