Antistatic products
Normal laying using high performance acrylic adhesive which has low water content. The flooring has antistatic properties of its own. These properties do not depend on the laying method used. Copper strips are not necessary.
Dissipative products and conductive products
There are two laying systems:
•with conductive adhesive and conductive primer,
•on a copper strip grid with a
Width: 1 cm | Average length: 250 lm |
Thickness: 6/100 mm | Weight: about 3.6 kg |
LAYING PROCEDURE FOR CONDUCTIVE FLOORING
WITH CONDUCTIVE ADHESIVE AND CONDUCTIVE PRIMER
The sheets must be unrolled and left in the room to be covered, with the adhesive, for at least 24 hours prior to laying.
Minimum ambiant temperature must be 15 °C.
1.Apply a conductive primer.
The coverage should be
Leave to dry for at least 12 hours.

3.Use 2 lm of copper strips for every 30 m2 for earthing. Connect the copper strip to the earth (1 earth for every 30 m2).
For rooms over 30 m2, lay copper strips at the periphery of the room and on the diagonal.

In order to achieve a regular and appropriate coverage change the spatula regularly.
Carefully follow the manufacturer's instructions when applying primer and adhesive. Ensure that the supplier can provide a 10 year guarantee for the conductibility of the adhesive.

LAYING PROCEDURE FOR RESIDENTIAL SHEET PRODUCTS
Check that the subfloor on which you intend to lay the floorcovering is smooth, free from grit, grease and wood treatments. Most of these floorcoverings should not be laid over damp areas although Texline and Griptex have higher tolerances for damp. Please refer to the Technical Department for further advice.
The floorcovering should be placed in the room where it is due to be laid for at least 2 hours prior to laying. The temperature should no less that 18oC.
If you plan to lay two or more widths please ensure sufficient material is purchased to allow for pattern match.
Sheet lengths should be reversed laid.
Most installations can be safely loose laid whilst ensuring that exposed edges that may be kicked up (such as doors and joints) are securely adhered to the floor using an 8 to 10cm width application of Gerflor E120 adhesive. Joints should be treated with Gerflor Cold Weld Liquid SG916 to ensure a strong bond. We recommend threshold strip to be fitted to doorways.
For permanent installations or where heavy domestic furniture such as washing machines are likely to be moved around, the floor covering can be fully adhered to the subfloor.
