As a hardwearing slip-free screed. Primarily for coping with
strong concentrations of sulphuric acid, this product can
also be used for other acids and in some strong alkali service
duties. Applications include bund areas, tanks, pipe work,
floors, decking, structural steel etc.

Before handling or using this product, the material safety data
sheet should be read and all precautions observed.

Metallic Substrates: The surface should be grit blasted
to SSPC-SP10 (ISO 8501-1 Sa 2½) or equivalent, blast
residues removed in accordance with normal surface
preparation procedures. Plasmet AR3 should be used as
a primer under the AR3 Screed. Over-coating times
should be strictly adhered to except on the advice of
Corrocoat Technical staff. It is essential that AR3 should
be applied with stripe coating between each main coat to
all weld edges and corners.
Concrete Substrates: Plasmet AR3 Screed resin and
hardener should be used as the prime coat. Concrete to be
prepared as per data sheet SP5.

Trowel, float or scraper.

Plasmet AR3 is designedforapplications over correctly
primed substrates. Wet film thicknesses of between
4 and 8 mm per coat are recommended. Dependent upon
environment and service conditions,total dryfilm thicknesses
will be in the order of 5 to 8mm. Where required the Plasmet
AR3 Screed resin and hardener may be used as a sealer over
the applied screed.
Plasmet AR3 Screed should not be applied at ambient or
substrate temperaturesbelow 41°F (5°C).Surface temperature
must be at least 37°F (3°C) above the dew point and RH
above 85%.

Base 2:1 Activator
Aggregate 3:1 mixed base and hardener by
weight

Remove the lids from the base and the activator. Pour all the
activator into the base and mix thoroughly. Ensure that no
unmixed activator remains. It is essential that a power mixer
is used to mix the base and activator. Once the mixture is
completely homogenous, incorporate the aggregate as soon
as possible and mix thoroughly

Approximately: 50 minutes at 68°F (20°C).
(Note this will vary with temperature, the temperature of the
aggregate will have a dramatic effect on the pot-life of the
mixed product.)

No minimum value. Product may be re-applied as soon as the previous coat of AR3 has gelled sufficiently to support the weight of the next coat and logistics allow. Maximum value 60 Hours at 68°F (20°C). Exponentially shorter at higher temperatures.
