Advanced Salt Neutralising Treatment for Damp & Salt‑Affected Masonry. A clear, water-based pre-treatment specifically designed to neutralise soluble salts (e.g. sulphates, chlorides, nitrates) in porous masonry. Essential for basement tanking, flood remediation, chimney repairs, rising-damp projects, and any situation where salt contamination could compromise coatings or tanking systems.. Key Benefits. Chemically stabilises hygroscopic salts, converting them into insoluble compounds to prevent efflorescence and render failure.. Deep-penetrating liquid reaches deep into brick, stone, or concrete for effective substrate stabilisation.. Stops damp patch recurrence, salt staining, and coating blow-off from rising salts.. Compatible as a primer with cementitious tanking slurries, renders, breathable coatings, and mineral finishes.. Product Details. Form: Clear, water-like liquid containing metal fluorosilicates. Pack Sizes: 5 kg & 10 kg.. Coverage: Approx. 17.5–22.5 m² per 5 kg two-coat system (dependent on porosity).. Shelf Life: 12 months unopened; store in cool conditions (+5 °C to +30 °C).. How to Use. Remove all salt-damaged plaster, render, coatings until bare porous substrate is exposed.. First coat (1:1 dilution with water) — apply via brush or coarse garden sprayer until surface saturation.. Allow to dry for 6–18 hours, depending on temperatures.. Second coat neat — reapply until saturation.. Once fully dry, proceed with tanking, rendering, or decorating — no additional wait time required.. Usage Guidelines & Limitations. Only for clean, bare, porous masonry. Not suitable for gypsum plaster, bituminous coatings, painted or sealed surfaces.. Can be applied indoors with adequate ventilation — low odour, water-based.. Not a permanent finish—must be followed by waterproofing, rendering, or coatings.. Avoid use outside +5 °C to +30 °C to ensure proper absorption and reaction.. Ideal For. Basement waterproofing (Hey’di K11 systems). Chimney breast refurbishment. Flood-damage remediation. Rising damp salt stabilisation. Any porous masonry prior to coating application
