Adawall 'Rendering Mortar'
Cement-free rendering mortar
Applications
Adawall Render Mortar can be used as an external or internal dehumidifying render on masonry subject to rising damp.
As a dehumidifying render over stone (especially porous, such as those of a lime nature) or brick structures, including burnt bricks (walls, columns, vaulting, etc.) and wherever saline efflorescence exists.
Restoring stone, brick or friable renders bonded with mortars which were originally mechanically weak.
Characteristics
ARM is a pre-mixed light-coloured cement-free powdered mortar based on special hydraulic binders with synthetic fibres and fine additives, with pozzolanic activity.
After ARM has been mixed with water in a mixer, it forms a sulphate resistant plastic-thixotropic consistency mortar, that is easily workable on both vertical surfaces and ceilings.
Mortars prepared with ARM are very similar to the old mortars based on lime, pozzolan-lime or hydraulic lime originally used in the construction of historical buildings in terms of colour, mechanical strength, modulus of elasticity and porosity. Compared to the original mortars, however, ARM based mortars possess a durability that make them virtually indestructible in the face of natural aggressions: rain, freeze-thaw cycles, cracks caused by plastic shrinkage, alkali-aggregate reaction, and above all, attack by the sulphate salts that are often present in masonry.
ARM based mortar has the porosity and transpirability properties of antique lime and pozzolan based mortars. This allows for the crystallization of salts in its porosity and a slow and gradual evaporation of capillary flow of rising damp from the foundations. The technical data sheet (final performances) lists some examples of typical data relating to the principal properties of ARM mortar in the plastic and cured state.
