For the preparation of the substrate, make sure that the surface is clean, dry, free of impurities, and uncontaminated by oil or grease.
METHOD OF APPLICATION
For the renovation of previously coated surfaces, make sure that signs of mildew and fungus are removed from the surfaces to deter subsequent growth. Wash surfaces vigorously with a solution of 1 tablespoon of detergent and 1 to 2 pints of liquid bleach in 1 gallon of water (0.125 to 0.25 liters per liter of water). Rinse thoroughly with clean water. Pressure clean (2100 psi min) to remove all impurities, laitance, and peeling. Allow surfaces to dry before proceeding (at least 24 hours or longer if the surface is porous). Repair delaminated stucco, damaged concrete, brick, and concrete block using Pioneer Pro Water-Tite 200 Barricade.
For sills, all stucco windows sills should receive a coat of brush-grade patching compound to render a smooth surface.
For parapets, do crack repair and treat backside of parapets in the same manner as exterior walls, terminating at roof counter flashing. If the top of the parapet wall is exposed to masonry, apply a coat of patching compound to create a smooth, well-drained surface. Recaulking of reglet may be required.
Recaulking of old windows is essential in the waterproofing and renovations of existing structures. Perimeters, joints, and mullions should be inspected and recaulked as required.
For new construction of stuccos (trowelled, floated, or blown on), all stucco must be cured for at least 28 days prior to application of Water-Tite 200 Barricade. Surfaces should be clean and free of oil and grease.
On clean and unpainted surfaces, apply one Water-Tite 200 Barricade Prime coat. As finishing coat, apply Water-Tite 200 Barricade at 20-25 sq.m/4L in 2 coats.
For pre-cast and cast-in-place concrete (cured 28 days), prepare the surface by removing all impurities and contaminants that may affect adhesion. Smooth precast or cast-in-place may require acid etching. In such cases the surface must be first dampened, then acid cleaned and etched with 1:1 solution by volume of commercial muriatic acid and water followed by a thorough pressure wash to remove the acid.
Allow surfaces to dry (at least 24 hours), then apply Water-Tite 200 Barricade Prime coat at a rate of 30-35 sq.m/gallon in 2 coats. A finish coat must be applied in a pinhole-free, continuous membrane for waterproofing integrity.
