Cement-based waterproofing coating, used for sealing and protecting structures exposed to active or passive water.
Underground parking areas
No need for surface to be dry, can be applied on to damp substrate.
Excellent waterproof barrier.
Excellent adhesion properties to sound substrate.
Ease of application, simply mix and apply by brush.
Each 25kg will cover 6m² in two coats. The above figure will depend on site conditions.
All surfaces must be clean, properly cured and sound. All Loose material must be removed mechanically, either by wire brush or sand/water blasting. The surface must be free from oil, paint, grease or any other product that might reduce the bonding process.
SWS Slurry is a two-component system, requiring the addition of pre-diluted Bondaid Plus (Liquid).
Mixing Bondaid Plus (liquid)
Use a clean empty container and add 5 litres of undiluted Bondaid Plus into the container.
Add 20 litres of clean water to the container.
This will make 25 litres of pre-diluted Bondaid Plus. (if you purchased the SWS Waterproofing Kit, no pre-dilution will be required).
Mixing SWS (Powder) and Pre-diluted Bondaid Plus (Liquid)
Only mix sufficient product that can be used within 40 minutes.
Pour pre-diluted Bondaid Plus (Liquid) into a clean mixing bucket. 6-8 litres of
pre-diluted liquid is required per 25Kg bag of SWS Slurry.
Slowly add SWS Slurry (Grey powder) to liquid while mixing (mechanical mixer
A lump-free consistency should be obtained.
Let product stand for 5 minutes and re-temper if necessary.
Dampen the substrate thoroughly with clean water before applying SWS Slurry. Ensure that the substrate is still damp, apply the first coat with a hard bristle brush to a thickness of 2mm. Once the first coat has dried sufficiently (2 to 6 hours) a second coat can be applied; a third coat might be necessary on areas of high water infiltration.
NOTE:Flexseal Membrane can also be used with the SWS Slurry to seal cracks and to re-inforce points of stress like corners and joints.
The maximum thickness in one application should not exceed 3mm.
Protect from wind and direct sunlight for at least 12 hours.
Uncured SWS Slurry can be removed with water.
Cured material can only be removed mechanically.
