Bond It TANKING SLURRY Grey 20Kg
A blend of Portland cement, quality graded aggregates and chemical modifiers, which provide a waterproof coating system.
- High water resistance.
- Excellent adhesion to most common building materials – see surface preparation.
- Water-based – safe to apply on damp surfaces.
- Easy application – applied by brush.
- Resistant to positive and negative water pressure up to 7 Bar.
- WRAS Approved:
- CE Approved: Conforms to EN998-1:2010.
For use on tanks, pits and swimming pools, above and below ground walls and floors, cellars, underground rooms, interior spaces, e.g. ducting, party walls, lift shafts and fish ponds. Can be used in conjunction with Bond It Plug-It (BDH106).
- Suitable for use with; brick, stone, and concrete surfaces.
- It is recommended sources of water and damp are removed. A damp proof course should be employed.
- All contact surfaces must be clean and sound, and free from dust, grease particles and loose material or
previous coatings. The surface must be prepared using abrasive tools, jet washing or wire brushing and any
debris removed with clean water. A sound mechanical key surface must be achieved prior to slurry or backing
render application, otherwise damp will build up under the tanking coating and will affect the bond to the
- Tap off water pressure where necessary insert a fillet at floor and wall joint.
- Running water and surface defects, such as holes, cracks or fractures should be filled with Bond It PLUG IT.
PLUG IT can be over coated with TANKING SLURRY as soon as it is cool and dry to the touch.
- Under normal applications, no priming is required. For difficult surfaces, Bond It EXTERIOR PREGRIT or SBR ADMIXTURE may be applied as a primer coat.
- Seal around all services and pipes with Bond It GRIPBOND PRO HYBRID SEALANT.
- The water required to produce the coating is 5 Litres of clean water per 20Kg of dry material.
- Pour the required quantity of water into a suitable mixing bucket/container. Slowly add the powder to the
water whilst continuously mixing with a mechanical paddle/stirrer.
- Mixing should be continued until all the powder is homogeneously combined into a “creamy” consistency.
As a rule of thumb – when the block brush is placed into the mix bristles first the non-bristle part should float
on the surface when the correct consistency is achieved.
- Additional water will reduce the effectiveness of the product.
- Do not mix more product than can be applied in a 60 minute period.
How To Use
- Bond It TANKING SLURRY can be applied when both the surface and air temperature is in the range of 5°C to 25°C.
- This product is susceptible to frost damage.
- Dampen the surface, ensure no standing or pooled water is present.
- This is a two coat application.
- Apply the first coat to a thickness of 2mm in a vertical direction, working the slurry into any pinholes, crevices
or edges thoroughly with a brush.
- Rollers can be used over larger sections but the surface should be inspected for any gaps or breaks in the coating.
- The slurry needs to be a continuous film for it to be effective, this is especially important at the floor/wall junction.
- Inspect the coating after approximately 3 hours for breaks or gaps.
- If the film is consistent, touch dry and fully adhered apply a second coat horizontally, as this will ensure complete coverage of the substrate.
- Do not re-temper stiffened material.
- Once applied protect from frost, direct sunlight and wet weather.
Do not apply over plaster, wallpaper or paint as the dampness will be retained under the Bond It TANKING
SLURRY and cause the plaster, wallpaper or paint to fail to take all subsequent coatings along with it. Not suitable for wood, plastic or fabric. Not suitable for Gypsum based plasters. Stainless steel form details only to be used.
Drying times are affected by the substrate, the moisture content of the substrate, the temperature of the substrate and the air. Under standard conditions, the film should be touch dry in 2 hours and thoroughly dry in 6-8 hours. Good ventilation is essential for correct drying and curing of the product. Dehumidifiers or other heat sources to accelerate drying must not be used. Protect from frost, direct sunlight, and drying winds for 24 hours.
Note: TANKING SLURRY is not designed to be a final wearing coat.
It is recommended that Bond It TANKING SLURRY is not overcoated until after 5 days. If plastering, only a cement-based renovating plaster can be used. Solvent-based paints are not suitable. Water-based paints can be used however, the first coat should be of a matt emulsion type, not silk or similar.
One 20Kg bag is sufficient to cover approximately 12m2.
