TYPE A PVC-Cold-Welding Liquid

Cold-Welding of PVC-floor coverings / PVC-wall coverings with closely-cut seam

Field of applicationff Seam sealing of PVC-floor coverings / PVC-wall coverings with closely-cut seam (new installation with double cut)

Characteristicff Firmly mounted steel needle with special cap

Propertiesff very high seam tensile strengthff durable, waterproof seam sealingff nearly invisible seamsff ready for use and reusable

ProcessThe steel needle penetrates deep into the seam area, opens it temporarily and the cold-welding liquid flows along the needle into the seam. Thus adjacent sheets will be temporarily dissolved and joined together strongly and permanently in the whole cross section of the seam. To protect the surface of the floor covering the seam area will be covered with a special masking tape before welding.

Delivery programmeAvailable in displays with 30 pieces each.

The durability lasts 3 years from the date of manufacturing, if the product is always kept dry, free of frost and not stored above 30 °C.

Remove the masking tape about 10 minutes after the welding by pulling it steadily backwards at an angle.

Attach a special masking tape centred over the closely-cut seam and press on with the seam roll.

With few tools you achieve a lot!

3 steps to a successful seam sealing exemplified by TYPE A

The result: A nearly invisible and waterproof seam!

Cut the masking tape in the seam area with a rolling knife, a trapezoid blade or a hook blade. In case of stiff or little flexible PVC-floor coverings (for instance Commercial Floor Coverings) warm up the seam area to a maximum of 40 °C by

using a blow dryer or an iron before welding.

Always work with both hands! Hold the tube in such a way that the index finger of one hand guides the cannula and the other hand holds the tube.Press the needle deeply into the seam, go through the seam area steadily and control the rinse in a way to get an approximately 5 mm wide moistening on top of the masking tape.

3. PVC-Cold-Welding with TYPE C

Precautionary we recommend the use of safety gloves approved for Tetrahydrofuran for the prevention of skin contact (splash protection).

3.1 Gaps from 0.3 – 4 mm (Repair Works)

Clean the seam area (glue remainders, dirt et cetera); fix lose seams onto the ground. Go through the seam with the tube and dose the PVC-cold-welding paste in such a way that the gap is filled entirely. For smaller gaps use the aluminium nozzle which is included. Remove the plastic stopper; it is meant for cleaning the nozzle. The volume of the applied paste reduces about 75 % while drying. Depending on the width of the gap and the thickness of the floor covering the curing time is from 2 to 12 hours. The process can be repeated every 2 hours, in case the gap is not filled entirely after drying. Swellings in the seam area of the PVC-floor covering will decrease.

3.2 PVC-Wallpapers

PVC-Wallpapers can be welded by using the aluminium nozzle which is included. Remove the plastic stopper; it is meant for cleaning the nozzle. Bring the aluminium nozzle evenly and centred onto the seam and apply the PVC-cold-welding paste steadily, working from top to bottom alongside a straightedge. The volume of the applied paste reduces about 75 % while drying, therefore do not wipe off any paste but let it dry (about 30 minutes).

4. PVC-Cold-Welding with TYPE A

4.1 Explaining the ProcedurePress the special masking tape firmly to the PVC-floor covering by using a seam roll (article no. 50020), ensuring that no cold-welding liquid penetrates beneath the masking tape.

The patented needle system opens the seam area briefly and the cold-welding liquid runs along the needle into the whole cross sec-tion of the seam. The adjacent edges are moistened by the cold- welding liquid, temporarily dissolved and melted together, becoming strong and durable after a short period of time.

The overlapping laid floor layers (3 to 5 cm) will be cut in one step alongside a metal bar (double cut).

After about 10 minutes the cold-welding liquid on the masking tape is dry and the tape has to be removed steadily backwards at an angle. Swellings in the seam area of the PVC-floor covering will decrease. The result is a barely perceivable seam with a high seam tensile strength. The seam can be walked on after about 30 minutes.

Precautionary we recommend the use of safety gloves approved for Tetrahydrofuran for the prevention of skin contact (splash protection).

Shake the tube well before use. While opening the tube (screw-top facing upwards) make sure that no cold-welding liquid reaches un-covered areas of the floor covering. Clean the nozzle and the needle before use with a clean cloth. Always work with both hands! Hold the tube in such a way that the forefinger of one hand is on the nozzle and the other hand holds the tube. Press the needle deeply into the seam, so that the cold-welding liquid can flow into the forming opening. Go through the seam area steadily and control the rinse of the cold-welding liquid by lightly squeezing the tube. The dosage of the cold-welding liquid is at its best if an approximately 5 mm wide moistening in the form of a closed film appears on top of the masking tape.

In case of hard and little flexible PVC-floor coverings (for instance Commercial Floor Coverings) warming up the seam area (to a maxi-mum of 40 °C by using a blow dryer or an iron) before welding enables an easier and more even guidance of the needle in the seam.

Easily cut the masking tape with the rolling knife (article no. 50010) in the seam area. Alternatively a straight blade or a hook-blade can be used. It is important not to damage the edges of the floor layers while cutting the tape. This can be done effectively by pressing the knife deeply into the seam, resulting in a good guidance.

Clean the seam area and fix a special, even masking tape (article no. 50000), which is resistant against our cold-welding liquid, centred over the closely cut seam. This is absolutely necessary to avoid damage to the floor finish (e.g. made of Polyurethane) of the floor covering.

In case the PVC-floor covering is not glued holohedral on the floor (please consider the manufacturers recommendations), the seam area has to be fixed to the surface by using a proper double-sided adhesive tape. Press the floor layers, which have to be laid tightly, firmly onto the double-sided adhesive tape.

After the double cut remove the cut-offs of the upper and lower layer.

2.2 Preparation for Cold-Welding

Place special masking tape (article no. 50000) centered over the seam.

Press the special masking tape firmly to the PVC-floor covering by using a seam roll (article no. 50020).

Easily cut the masking tape with the rolling knife (article no. 50010) in the seam area. Alternatively a straight blade can be used.

In case of hard and little flexible PVC-floor coverings (for instance commercial floor coverings) the seam area has to be warmed up to a maximum of 40 °C by using a blow dryer or an iron directly before the welding.

2.3 Cold-Welding of the Floor Covering Edges

With one hand press the screwed T-nozzle deeply into the seam and pull along. With the other hand control the rinse of the cold- welding paste so that an approx. 5 mm wide moistening appears on top of the masking tape.

After about 60 minutes pull off the masking tape backwards at an angle.

2.4. Cleaning of Nozzle TYPE T

Immediately after use screw off the T-nozzle and close the tube. Break enclosed plastic strip the long way in half and insert immedi-ately into both wings of the nozzle.

Before using the tube again pull out backwards both strips, re-screw nozzle again and test flow of the paste.
