How to weld vinyl sheets together.

A bead of the same materials is extruded between two sections and then the two sections are immediately pressed together. Then apply heat again. The heat in the extruded bead is sufficient to cause it to weld to the adjacent surfaces. If you notice part of your design lifting up you can just hold it down with your finger while you pull off the vinyl surrounding it.

Then immediately apply pressure to fuse them together allow to cool down if too hot. Allow the adhesive to sit for the set time specified on the. Spread vinyl floor adhesive on the floor with a 1 16 by 3 32 inch notched trowel. Wait for the plastic to begin melting joining the pieces of plastic together.

Apply a uniform bead 1 8 to 1 4 wide centered at the seam. Notice the groove in photo 5 below has a more pronounced groove on one side of this failed heat weld. As the needle is drawn along the seam the sheets separate slightly which will allow the fluid to flow between them. Fit a tack welding nozzle on your welding gun then apply a little bit of heat.

Start at a corner and slowly pull the vinyl up at an angle making sure all the parts of your design remain attached to the carrier sheet. Roll the edges of both sheets away from the seam. Using the low setting on my heat gun gently heat up the two sheets till they get tacky. The bead of sealer must flow back together around the needle after it has been applied to the seam.
