KA Tanking Slurry 25Kg White

Product Information

The nozzle must be held at a 90° angle to the substrate being treated and the distance between the nozzle and the surface will vary depending on the spray gun / compressed air used. The internal walls of a property are vulnerable to water ingress and damp. This means you are open to a whole load of potential problems. If you want to take steps to protect against this or deal with existing damp walls then you should consider wall tanking. We take you through the tanking methods available and the products you will need along with our usual no-nonsense advice. Multicrete Tanking Slurry is to be mixed and used within 30 minutes @ 20˚C so any excess that is mixed and not used within the allotted time will be wasted. The mix ratio that is recommended is approx 5.5-6 litres of fresh clean water per 25kg. Vandex BB White is a version of Vandex BB75 based on white Portland cement. Its characteristic white colour makes it particularly suitable for use on exposed surfaces, e.g. potable water reservoirs. Vandex BB75 Z Note:all tanking products are prone to sweating during the drying out phase and if left exposed after the product has cured. We suggest they are always covered as above and/or adequate ventilation is installed to manage the humidity. PermaSEAL - Complete Solutions. Made Possible.

Above ground, we recommend a 3mm mesh membrane (the mesh provides an excellent key for dot and dab plasterboard or direct rendering) or 3mm clear membrane that is suitable for use behind stud work. Tanking slurry can be used on a damp wall above ground to stop the passage of water. Ideally, you will want to identify and resolve the source of damp before applying it.

Customer Reviews

Cementitious tanking slurry - a paint-like substance that has been chemically engineered to form a protective barrier when applied to internal walls. Retaining Walls and columns in reservoirs • Swimming Pools prior to tiling or painting • Concrete drinking water tanks • Water Treatment and sewerage plants • Foundation Slabs • Underground Cellars, basement car parks, garages, etc. • Pre-stressed and pre-cast concrete units • Tunnels, silos, irrigation channels • Bathrooms, kitchens, etc • Lift Shafts • Vehicle maintenance pits

For more information, read our guideon tanking a cellaror waterproofing a garage with tanking slurry. PermaSEAL - Complete Solutions. Made Possible. Below ground, you can use tanking slurry by itself as a form of Type A Waterproofing (barrier system). This offers you reliable protection from water ingress. Having said that, many people like the reassurance of drained protection with a cavity drainage system ( wall& floor membranes and sump pumps). If there is already water ingress of a substantial volume in a cellar or basement, you can use the tanking slurry to reduce the load on the system and the pumps before installation. If you're unsure which basement waterproofing method is best for you, then read our guide. For maximum effectiveness, it is essential that the applied layers of Vandex BB75 are kept damp for at least 5 days and protected against evaporation by sun and wind. Careful post-watering should be carried out at intervals, starting from the day following the application. Alternatively, the surfaces can be covered with plastic sheeting, wet mats or moist sand. The use of curing compounds is not recommended. More often than not, walls below ground like basements, cellars and sunken garages are surrounded by earth. This means that moisture, water pressure and ingress are serious considerations. How do you tank a wall? Vandex BB75 Z is formulated to have enhanced sulphate resistance, making it suitable for use in sewage treatment plants and sewer / manhole refurbishment projects.

Specifications

The waiting time before applying the second layer is approximately 2 – 4 hours, depending on local climatic conditions such as humidity, temperature, etc. The first layer must not be damaged during application of the second layer. Generally speaking, the second coat should cure within 24 – 48 hours. Temperature and ventilation both affect tanking slurry drying times. Cold temperatures and poor ventilation will lengthen the amount of time it takes to dry. The freshly treated surfaces should be protected from rain for a minimum period of 24 hours. Surfaces treated with Vandex BB75 should be protected from frost for at least 5 days. If necessary, cover them with insulation mats. Sometimes you may be dealing with a live leak in a basement or cellar. In these situations we recommend a rapid tanking system to stop the ingress. Wear protective overalls and a mask as the chemical compounds in cementitious slurry can be harmful to eyes and skin.
