Sakrete joint mortar Black 25 kg

Sakrete Joint Mortar UA is a low-efflorescence dry cement mortar that is suitable for grouting different types of stone in masonry. It is specially designed for applications where the masonry is exposed to strong weathering conditions, water-retaining masonry, and high mechanical stress, both indoors and outdoors.

The Sakrete Pointing Mortar UA offers several unique properties. It is more resistant to salt loading than normal cementitious mortars, which is especially beneficial in maritime climate and coastal areas. In addition, it minimizes the risk of 'burning', resulting in strength retention. This joint mortar is low in efflorescence, which prevents white scale efflorescence from occurring. It can be compacted better with less energy and has hydraulic setting properties, which contributes to weather and frost resistance.

It is important that the masonry is at least 2 weeks old before grouting. A longer waiting time is recommended at low temperatures and hard types of stone. When preparing the joint mortar, Sakrete Joint Mortar is mixed with approx. 2.0 litres/25 kg of clean tap water until a moist, homogeneous joint mortar is created.
