The Ardex B1 2mm V Notch Trowel is for use when laying decoupling membranes or other matting with Ardex AF200 Plus Adhesive, Mapei Ultrabond Eco VS90 Plus Adhesive or any other LVT or Vinyl Adhesive. This trowel features a 2mm V-notch for creating a ribbed bed of adhesive on flat and level substrates, prior to laying any matting.
For maximum coverage, use the Ardex B1 2mm V Notch Trowel at a 45° angle.
Dry lay the uncoupling matting prior to adhering it to the subfloor to ensure accuracy of fitting.
Apply a ribbed adhesive bed to the subfloor using the B1 V-shaped notched serrated trowel, and leave to air for 5-10 minutes. The matting must then be laid into the wet/tacky adhesive fleece-side down, and pressed firmly into place using a steel trowel, abutting all edges.
The matting must be installed within the specified open time for the adhesive used and can be adjusted and repositioned within the specified adjustment time. Tiling can commence immediately.
NOTE: The airing time is dependent on the absorbency of the subfloor and site conditions. Higher temperatures will shorten and lower temperatures will lengthen the time.
