Description

WBA is a High Build Acrylic Membrane which displays outstanding performance where flexibility and long tern durability is required. The combination of low Carbon Dioxide absorbtion and high water vapour transmission makes WBA the preferred coating system for both new and remedial maintenance projects.

WBA 9000 is formulated on a unique flexible resin and long life pigments. The high resin solids ensures a superior film build which provides maximum performance in a wide range of climatic conditions.

WBA 9000 is the result of a product evolvement based on advanced technology, proven and improved over the past decade. These formulations are the result of a commitment to quality in research, product development and manufacturing.

PREPARATION

  • Do not apply coatings if temperature is below 15°c or over 30°c
  • Do not apply coating if rain is imminent
  • Not recommended for below grade waterproofing or where water pressure is from within the wall.

The surface to be treated shoud be dry clean sounds and free from oil, grease, flaking paint and laitence and othe deleterious materials. Some paint may be overcoated. New concrete should be minimum 28 days old before application commences. All cracks or holes exceeding 2mm are to be repaired before application commences.

APPLICATION

Apply one coat of the appropriate Westox Primer. Apply by brush, roller or airless spray to the prepared surface.

VERTICAL SURFACES

Apply one coat at the rate of 4m2 per litre and allow to dry. Apply second coat at the rate of 4m2 per litre W.F.T. approximately 250 microns. Finished dry film thickness (D.F.T.) should then be approximately 275 microns. (Total D.F.T should never be less than 250 microns).

HORIZONTAL SURFACES

Apply first coat to primed surface at the approximate rate of 2m2 per litre and whilst wet roll out reinforcing mesh and embed, working with a brush to ensure complete saturation of fabric.

Allow minimum 8 hours before application of second coat of membrane at the rate of 2m2 per litre and allow 24 hours to dry.

Apply third coat of membrane at the rate of 2m2 per litre at right angles to previous coats. Thoroughly check surface after 24 hours to ensure that complete coverage has been attained and no pinholing is evident. Surface will be touch dry in 8 hours, and will accept foot traffic after 48 hours. Will achieve full cure in 7 days.

  • Avoid water ponding for first 3 days after application
