SpECtop SRE500 may be used in industrial
and commercial situations to provide an abrasion
resistant finish in areas subjected to traffic, chemical
attack and surface water, such as:
· Car parks
· Loading bays
· Walkways
· Chemical production facilities
· Dairies
· Beverage production units
· Wet working area
· Abrasion resistant
· High build and therefore requiring low
maintenance
· Resistant to a wide range of chemicals
(see Chemical Resistance Chart)
· Solvent free to minimise disruption
· Slip resistance to suit site conditions
· Available in a range of colours to demarcate
areas and provide a light reflective floor
Preparation
It is essential that adequate preparation is carried
out prior to the application of SpECtop SRE500.
Grit blasting is recommended to ensure the removal
of all laitance, grease and oil. The resultant surface
should be dry and dust free. Cracked and damaged
areas must be made good with appropriate repair
materials.
Priming
SpECtop SRE500 may be applied to properly
prepared concrete without the use of a primer
providing:
· The moisture level of the concrete is less than
75% when tested in accordance with BS8203
Annex 4.
· The wet film thickness for the first coat does not
exceed 250µm. It is essential that a wet film
thickness gauge is used to monitor average
thickness during application.
Otherwise use SpECtop Primer F1 or SpECtop
Primer FX as follows:
The contents of the curing agent should be emptied
into the base component and stirred with a spatula
until the product appears uniform.
The mixed primer should then be applied to the
prepared substrate by a stiff brush at 10-15 m²/litre.
If the primer appears to be absorbed into the
surface easily, it will be necessary to apply a
second coat once the initial coat is tack-free.
It is essential that the primer is tack-free prior to
the application of the topping. The application
of SpECtop SRE500 should commence between
8-24 hours after priming. If this period is exceeded,
then the surface of the primer should be lightly
abraded and a fresh priming coat applied.
Mixing
SpECtop SRE500 is supplied in a two- component
kit consisting of a curing agent and a pigmented
base component.
Both of the components
should be briefly stirred to
ensure that any settlement
products are fully suspended.
Empty the entire contents of
the curing agent into the base
component. To ensure that
all material is extracted, the insides of the tins
should be scraped. The curing agent and the base
component should be mixed with a slow speed,
heavy duty electric drill and a spiral mixing paddle
for at least five minutes and until the material
appears uniform in colour and consistency.
Application
The first coat of SpECtop SRE500 is applied by a
medium pile roller at a desired wet film thickness.
The quantity of material used per coat and the
number of coats may vary dependant on the
porosity of the substrate and the surface profile.
If a slip resistant profile is required, the first coat
is completely blinded with SpECtop NS GRAINS.
This should be carried out while the coating is still
wet.
When the first coat has reached its initial cure
(12 hours @ 20°C), the excess aggregate should
be removed by vacuum from the surface.
The top coat is then applied again by a medium pile
roller. Where a smooth finish is required, the top
coat is applied as per the first coat.
For slip resistant floors the topcoat of SpECtop
SRE500 should provide a continuous film of
material and also completely seal the surface of the
SpECtop NS GRAINS. The consumption rate of
materials for this type of application will be heavier
for the top coat due to the increase in the surface
area to be coated.
Where UV resistance is required, overcoat with
SpECtop UV.
