Care should be taken when handling the product in line with current manual handling regulations.

Preparation

Visqueen Polyethylene Damp Proof Course can be cut with a sharp retractable safety knife or robust scissors.

Installation

When built into a masonry wall construction, Visqueen Polyethylene Damp Proof Course should be installed on an even bed of wet
mortar, and any perforations in adjacent courses of masonry should be completely filled with mortar. To ensure mortar adhesion,
as soon as possible after laying the DPC, lay at least one further course of masonry including a bed of mortar.

If positioned on the sleeper walls below a suspended ground floor e.g. beam and block floor system, the DPC can be dry laid,
however all sharp protrusions must be removed from the substrate. The DPC must extend through the full thickness of the
masonry wall, including pointing, applied rendering or other facing materials.

All DPC to DPC laps should be a minimum of 100mm and bonded with Visqueen Zedex Jointing Tape.

Usable temperature range

It is recommended that Visqueen Polyethylene Damp Proof Course and all associated system components should not be used
below 5°C.
