CERESIT® CC 81 can be used as an additive for adhesive slurries, adhesive bridges, cement-based plasters and for joint mortars used on faced brickwork, clinker masonry and glass bricks. For ensuring reliable bonding and crack resistance of cement- bound repair mortars. For improving workability and increasing compaction of the mortar. For increasing flexibility, elasticity and bonding to the surface. For reducing early drying-out.
Mortars with the addition of CC 81 adhere to all solid, load-bearing and clean mineral surfaces free of substances which can cause separation. Completely remove surface layers of insufficient bearing strength or any contamina-tion. Dedust and slighty prewet thesurface.
Dilute CC 81 in clean, clear water following the specified mixing ratio (see Technical Data). Use this liquid to prepare the mortar. Apply the necessary adhesive bridge, adhesive slurry or pneumatic mortar prepared at the suitable mixing ratio. Then apply the mortar onto the still wet adhesive bridge and rub over. Wet aftertreatment may be necessary.
Use CC 81 only in dry conditions and at temperatures of +5 °C to +35 °C. Problems may arise if CC 81 is used in combination with other additives.Carry out preliminary tests or obtain advice. Use cement or lime/cement as a binder.
Ceresit CC 81 can be used as finishing agent for joint mortars used on faced brickiwork, clinker masonry and glass bricks. Not suitable for priming or sealing.
Ceresit CC 81 can be used as finishing agent for mortars with hydraulically setting binders. For adhesive plasters, thin-layer plasters and levelling plasters.
Use CC 81 only in dry conditions and at temperatures of +5 °C to +35 °C. Problems may arise if CC 81 is used in combination with other additives.
