DESCRIPTION

With KÖSTER Mortar Tight, creating a waterproof render, screed or simple sealing slurry on the construction site using sand, cement, and water is possible. KÖSTER Mortar Tight is added to the mixing water. KÖSTER Mortar Tight improves the density of the mortar structure. It makes the mortar water-repellent (hydrophobic) and promotes selfhealing of micro-cracks through crystallization. As a result, the mortar becomes waterproof and the capillary absorption capacity is reduced. KÖSTER Mortar Tight is free of chlorides and nitrates.

AREAS OF APPLICATION

KÖSTER Mortar Tight increases the impermeability of mortars and slurries against ground moisture, hydrostatic pressure, and driving rain. It is used for the production of waterproof renders, screeds and slurries for internal waterproofing, of underground structures such as basements or swimming pools. It can also be used externally for the production of water-repellent renders and in various other areas where a waterproof mortar is required, e.g. for tanks, shafts, masonry, etc. Always ensure that the intended application complies with the requirements of local building authorities. The performance of KÖSTER Mortar Tight is dependent on correct on-site mixing and application and only high-quality materials should be used. A self-made mortar with KÖSTER Mortar Tight cannot replace approved or certified sealing mortars or sealing slurries.
