Application BuildenSeal-202 must be applied at least two coats. The first coat is applied by stiff brush to cover the area evenly within 1 hour of it being mix.
The second coat may be applied with a soft brush or roller when the first layer has become tack free after 2 to 4 hours depending on the ambient condition.
The recommended thickness of application is 1 mm per coat depending on the expected water pressure and abrasion.
The maximum thickness per application should less than 1.5 mm.
For areas which exposed to sunlight, protective topping / screed / render should be installed for further enhance the durability of BuildenSeal-202.
