MIXING
Mix the entire 15kg bag of powder with 2.9 - 3.1 Litres of clean, cool water. Slowly add powder to the water while mixing with a suitable electric drill and mixing paddle. Thoroughly mix for only 1 minutes to a lump free consistency and apply directly. Not mixing for the recommended time or additional water may result in product irregularities and possible product failure.
APPLICATION
Using Sikafloor®-045 Rapid 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®-045 Rapid 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®-045 Rapid.
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®-045 Rapid into the concrete void. Sikafloor®-045 Rapid 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®-045 Rapid must be protected from damp, condensation and all forms of water while curing for at least 24 hours.
