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

FAQ
All of our C16 and C24 graded timber is regularised
Regularised timber is timber that has been processed to have a uniform shape and size. This means that the wood has been sawn and planed to remove any irregularities and ensure that each piece of wood has consistent dimensions. Regularised timber is often used in construction, particularly in the framing of buildings, as it is easier to work with and can be more efficiently installed than irregularly shaped timber.
We have one of the largest ranges of timber lengths, dimensions and grades available to buy online.
The variation you require will determine the exact lead time and delivery method.
Most orders arrive within 3-4 days, the maximum is 7 days. Please get in touch before you order if you need a specifc delivery date.
Delivery charges vary by postcode. To find out the delivery charge, add the item(s) you require to your basket and select CALCULATE SHIPPING at the bottom of the page.
Some orders are delivered on our own vehicles based in Leicestershire and Cheshire. We also use carriers including Yodel and Tuffnells. For some sizes and locations we use regional distributors.
If you'd prefer crane offloading rather than tail lift vehicle offloading for your brick order then this service is available for the majority of bricks that we sell. Charges are shown at checkout.
For deliveries of less than 6 packs then Taillift offloading is normally a more cost effective option
