SpECtite HP600 Primer is suitable when used in
conjuction with SpECtite HP600.
· Special blend of moisture curing urethane prepolymers in solvent and its chemical similarity
to SpECtop coatings ensures good adhesion
between the two within the specified overcoat
times.
· Acts as a sealer on porous substrate such as
concrete and will consolidate a friable substrate
such as that of asbestos cement.
· Acts as barrier coat on bituminous substrates
and improves adhesion to difficult substrates
such as non-ferrous metals.
Surface preparation
Surfaces must be sound, clean, dry, free from dust,
oil, grease and laitance etc. All traces of release
agents must be removed. On chalky and dusty
surfaces, all loose material must be removed by stiff
bristle brushing. Allow 28 days for new concrete to
cure and before removing laitance and applying
primer.
Roofs
Remove dust, dirt and loose chippings. Kill fungal
growth with fungicide and wash off thoroughly. Fill
cracks and voids with exterior mastic and cut open
felt blisters, apply SpECtite HP600 Primer
underneath and tack down. Allow for evaporation
of moisture.
Application
SpECtite HP600 Primer can be apply directly
from the can by brush or spray. One application will
normally suffice but some highly porous substrates
may require two.
SpECtite HP600 Primer is available in 5 litre and
15 litre pack with a theoretical coverage rate of
10-15m²/litre/coat depending on substrate texture
and porosity.
