Instructions for use

Instruction for Use

All surfaces should be clean, dry, free from grease, oil or dust. Remove all loose materials. Apply in the corners (wall-wall junctions and wall-floor), in patched areas, or on micro-cracks, around the pipe penetrations and construction joints a waterproofing layer of weber.dry 110 FX or weber.dry 130 PR or weber.sys protec, etc… With a flat brush, cut the sealing strip weber band, with scissors and embed it in the waterproofing layer with a small trowel to thoroughly cover all angles, cracks, joints, pipe penetrations, etc... A second layer of waterproofing material can be coated over the band if necessary (check datasheet of waterproofing product). For movements joints (i.e in terraces), weber band must be positioned in the shape of an omega, as it can be subjected to tension.
