Application steps

MIXING

Place the whole bag of powder in the mixing vessel and pour 3.5–4.5 litres of clean water in the powder. Mix until a homogenous workable mortar is achieved.

APPLICATION

Applied the well mixed Unicell® 40S mortar to the prepared and wetted concrete surface. Fill gap between the window frame and concrete surface by compacting the Unicell® 40S mortar firmly to fill all voids. Subject to ambient conditions, make good the mortar surfaces with steel trowel 2–3 hours after application.

CLEANING OF EQUIPMENT

Clean all tools and application equipment with clean water immediately after use.
