Application steps

APPLICATION INSTRUCTIONS

FLOORS/GENERAL:

All existing treatments shall be completely removed and the exposed concrete floor mechanically prepared, washed down and brushed to ensure full removal of all loose debris to give an exposed aggregate finish, free of laitance, and surface contamination.

MIXING

Place the correct amount of water into a mixer, add the mortar and mix until the water has been fully combined, approximate 3 minutes. The Sika®-1 Pre-bag Render Mortar should be mechanically mixed using a forced action mixer or drill and paddle mixer to limit the amount of air entrapment. A tumble mixer is not suitable for mixing.

APPLICATION

Refer to Sika-1 Waterproofing system datasheet for full application methods
