Consumption

Mix each 25 kg bag Sika®-1 Pre-bag Render Mortar with 3.1L of clean water. A mixed 25kg bag of Sika®-1 Pre-bag Render Mortar will yield ~12.3L of mortar which is sufficient to cover ~2m2 at 6mm thick
Application steps

APPLICATION INSTRUCTIONS

WALLS/BRICK:

All existing treatments shall be completely removed and the exposed surfaces roughened by mechanical or water blasting techniques, followed by washing down and brushing to ensure full removal of all loose material. Mortar joints should be bonded and sound. Any defective mortar joint should be raked out to a depth of 12.0mm and repointed using Sika®-1 Finishing Mortar made up with clean water.

WALLS/CONCRETE:

All laitance shall be removed to expose coarse aggregate by mechanical or water blasting techniques. On new concrete walls retarder can be applied to the face of the shuttering followed by wire brushing and washing of concrete surfaces.

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
