Application Information
Instructions for use

Surface Preparation

All surfaces where the waterstop is to be applied must be dry, smooth, clean, free from dust, laitance or loose materials. When otherwise necessary, it is highly recommended to use compressed air or a wire brush in order to remove further dirt, oil stains and other inconsistencies.

Application

Cut CORDOFLEX according to the required length and lay it along the joints accordingly. Gently push the cord against the joint with extra caution not to damage the skin of the material.

Make sure that the diameter of CORDOFLEX is approximately 20% to 25% (required depth to width ratio) greater than the width of the joint in order to ensure that the cord is tightly held in position. This procedure enhances further the aesthetic effect of the material when done on a firm base.

The joint should then be sealed with a suitable sealant from COLMEF product range.

Warning

CORDOFLEX is a combustible product. Avoid exposure to all sources of ignition or flame.
