K 112

Description

Special conductive adhesive

 

 

Very low-emission, special conductive dispersion adhesive for

– conductive PVC sheet and tile flooring

– conductive rubber sheet (up to 3.5 mm thickness) and tiles (up to 2.5 mm thickness)

Recommended e.g. for operation theaters and computer rooms, laboratories in potentially explosive production and storage areas. Ceresit K 112 meets the highest requirements for indoor air quality and environmental compatibility.

Properties

  • Light color and conductive

Step by step

SURFACE PREPARATION

Substrates must comply with the requirements of ATV DIN 18 365 “Flooring work”, BS CP 8203 & 8204 or comparable national standards. In particular, they must be clean, free from structural defects, firm, dry and free of substances which may impair adhesion. To level off any substrate unevenness, first treat with the appropriate Ceresit primer and then apply the recommended Ceresit levelling compound. Every 30 m2 fix a copper strip of approx. 1 m length. Use a conductive adhesive and always leave a protruding end (tail). In the case of rubber flooring, fix a copper strip lengthwise under each row of rubber tiles or strips, over the full length. Connect the copper strips transversely at the end of each row. Allow the copper strips to protrude every 30 m2. Only in cases that a copper strip grid in needed, apply this before.

APPLICATION

Apply the adhesive evenly to the substrate with a S1 notched trowel. Wet bonding: After a short open time of approx. 10 – 20 minutes, place the covering material into the still wet adhesive bed, taking care to avoid air pockets, and carefully rub it down to ensure good wetting of the back. The covering material must be free of tension and lie flat on the substrate, otherwise weight it down. Avoid rucking at the joints. Pressure-sensitive bonding (only for PVC coverings): On imprevious substrates, allow the adhesive to air-dry until it has taken on a uniformly yellowish to transparent colour (approx. 30 – 60 minutes). Then test with a finger to make sure it is touch-dry.  Contact bonding (e.g. for rubber floor coverings on non-absorbent substrates): Rubber flooring can be fixed on non-absorbent substrates only by contact bonding. Apply the adhesive on back of the floor covering with a smoothing trowel. In addition, apply adhesive on the substrate with a notched trowel (size S1). Allow both adhesive surfaces to dry to the touch (check by finger test as described under pressure-sensitive bonding). Then place the floor covering, but avoid entrapping air. Always press the ready laid floor covering in place by vigorously rubbing or rolling it down again. Wait at least another 24 hours before welding the joints.
