Precautions in Use

Duram Leak-Seal Tape is considered safe to use if used as intended.

Priming and Surface Preparation

Good preparation is essential. Surfaces must be sound, stable, dry, clean and free of dust, loose, flaking, friable material and substances that may diminish adhesion.

 

Surfaces must be sound, dry and free of contaminants, dust, dirt, oil, grease, waxes and any adhesion detracting substances and smooth and even enough to allow good adhesion to the surface.

Prime surfaces with Duram Primeseal  - our recommended primer, (or other suitable waterproofing primer as required for the Duram waterproofing membrane to be used), and allow to dry.

To corners and joints apply a flexible polyurethane joint sealant in the usual manner. The Duram Leak-Seal Tape can be applied directly and immediately over the sealant provided that the bead of sealant is no more than 10mm wide.

Application

Peel and stick the Duram Leak-Seal Tape , centred over the joint, crack or corner.  Overlaps should be at least 100mm.

It is important that pressure be applied uniformly to the entire areas of the tape to ensure a good bond.

Duram Leak-Seal Tape can be applied over the wet polyurthane sealant provided that the bead of sealant is no more than 10mm wide.

As soon as the tape is installed the Duram membranes can be applied over it.

Coat over the Duram Leak-Seal Tape with a suitable Duram waterproofing membrane extending to the substrate as would usually be done or required for that product. Refer to the product data sheet.

Suitable Duram waterproofing membranes include: Duram Multithane, Duram 195, Durabit EF, Durabit Reo, Azcoflex, Crystoflex, Pondseal, Duramax Maxiflex & Supreme.
