PRATIX® Aero Bond
PRATIX® Aero Bond is a cement-based, polymer-modified masonry mortar developed for laying aerated concrete blocks with thin joints. It provides high bond strength; the thin joint reduces thermal bridging in the wall and saves both material and labour.
Complies with class G M10 according to EN 998-2.
G: General purpose masonry mortar
M10: Compressive strength class (≥ 10 N/mm²)
Areas of Use
• For laying aerated concrete blocks
• For masonry in brick, hollow block and polystyrene concrete
• Indoors and outdoors, in loadbearing and non-loadbearing walls
• For partition and infill wall applications
Advantages
• High bond strength
• Saves time, material and labour
• Easy to prepare and apply
• Long pot life allows a large area to be laid from a single mix
• Resistant to freeze-thaw cycles
