SikaMur System


SikaMur® mortars consist of specially selected limestone aggregates, cements and air entraining additives. They are moisture vapour permeable, allowing the wall to dry out and are also designed to prevent efflorescence damage, improve thermal properties and protect against condensation. Suitable for internal or external application to damp masonry, including walls suffering from rising damp, containing salts or having undergone d.p.c. injection works.
