APPLICATION
Using Sikafloor® Rapid Patch prior to floor coverings:
Grading/Ramping
Once product is mixed immediately apply and begin working to heights required.
Product can be worked/shaped/shaved with the back of a trowel up to 20 minutes after application.
Using Sikafloor® Rapid Patch to repair concrete:
Patching concrete
On a well prepared clean and roughened concrete
surface a bonding primer is generally not
required, but pre-dampening of the surface with
water is recommended. After water has been
applied and allowed to soak the concrete surface
should achieve a dark matt appearance without
glistening and surface pores and pits shall not
contain water. The surface shall not be allowed
to completely dry before application of Sikafloor®
Rapid Patch.
If priming is preferred first diluted Sikafloor® 01
Primer 1:3 with water then apply by way of a brush till
all areas have been coated and allow to dry.
Once placed, a trowel is used to pack & shape
Sikafloor® Rapid Patch into the concrete void.
Sikafloor® Rapid Patch can also be left high of the
finished surface required and shaved using the trowel
until full set. Working time 15 - 20 min @ 23°C.
Note: Freshly applied Sikafloor® Rapid Patch must be
protected from damp, condensation and all forms of
water while curing for at least 24 hours.
