APPLICATION INSTRUCTIONS
SUBSTRATE QUALITY / PRE-TREATMENT
Substrates must be properly cured, structurally
sound, free of any loose or friable particles,
clean, dry and free of any contaminants such as
dust, dirt, oil, grease, cement laitance or efflorescence.
▪
Depending on the substrate condition and contaminants to be removed from the surface, perform adequate preparation techniques, such as
water-jet washing or blastcleaning, in order to
remove all traces of any materials that could reduce the product’s adhesion to the substrate.
▪
For applications in hot climates / environments
and / or on absorbent substrates, thoroughly
pre-dampen the surface immediately prior to
the product application, but avoid any ponding /
standing water on the surface, which must not
be damp to touch and not with a dark-matt /
wet surface appearance i.e. it must be saturated
surface dry (SSD).
▪
MIXING
Mix 25 kg bag with the necessary, above mentioned, amount of cold water, using an electric
blender with a suitable mixing spiral, in a clean
bucket. Add the SikaRep Fine PK powder slowly
while mixing continuously for at least 3 minutes
and until a homogeneous consistency is
achieved. Use a blender at 500 rpm maximum; do
not mix at faster rate because of mechanical
strength decay of the cured product. The obtained mix results very creamy, easily spreadable
and thixotropic.
APPLICATION
SikaRep Fine PK can be applied by trowel, spatula
or wet spray. As soon as the mortar has started
to set it can be smoothed by wooden or synthetic
float, styrofoam block or sponge. No additional
water must be used as it may lead to surface discoloration.
CURING TREATMENT
Where ambient conditions may lead to rapid surface drying, the use of light water fogging for 48
hours or application of a suitable water based
curing compound like Sika Antisol is recommended. Do not commence fogging until final set has
been reached.
CLEANING OF TOOLS
Clean all tools and application equipment with
water immediately after use. Hardened / cured
material can only be mechanically removed
