Apply it sparingly to one surface and press the parts together immediately. Hold in place until the bond sets. Do not reposition parts. Clean the adhesive applicator with a tissue and close it. Remove glue using moistened tissue. If you need to clean up larger quantities of uncured adhesive, moisten it and let it cure before carefully scraping it off. You can cut away cured adhesive with a sharp blade and remove it with acetone or boiling water. Exercise caution, though, because acetone can damage some plastics and is highly flammable.

Work in a well-ventilated area. Open your doors and windows before you begin or work outdoors. For extra protection, be sure to wear a respirator mask. You can find them at any home improvement store. Heat up your soldering iron.
A low-watt soldering iron works best for this project. To test it, hold it to the plastic. Cut a piece of metal to bridge large gaps. For larger gaps, such as where a piece of plastic has broken off, purchase some cable ties or metal wire. Clip off a piece big enough to lay over the gap. The metal combines with the plastic, making the plastic stronger. You could even use a spare paperclip laying around your house. Hold the plastic together.
Pick up the metal or tie you clipped earlier and place it where you want to weld. It should be over the area, not inside a crack. Melt the metal over the plastic. Try not to stretch or bend the rest of the plastic. If the edges of the crack cannot connect, you use a small piece of scrap plastic as a patch by melting the edges of the patch and the edges of the crack, and then fusing them together.
If you do use a piece of scrap plastic as a patch, cut the plastic to a size that fits the crack, and try to use the same type and color of plastic. Melt the edges of the crack with the soldering iron. Lightly rake the hot tip of the soldering over the edges of the crack until they melt and fuse together.
Be sure to heat the plastic evenly so it fuses together smoothly. Allow the plastic to fully cool before using it. Melting plastic can put off fumes that are harmful. Work in a well-ventilated area or wear a breathing mask to avoid breathing in the fumes. Allow the plastic to cool completely.
The plastic must cool completely in order for it to set. If you try to use the plastic before the crack is fully set, it may reopen and be harder to repair the next time. Remelting plastic can affect its appearance. Turn off and store the soldering iron. When you are done welding your plastic together, turn off and unplug your soldering iron and allow it to cool.
Wipe the soldering tip clean of any plastic residue that may have collected there. Then store the iron in a safe location. You may need to scrub the tip of the soldering iron with a brush to remove the residue. You can use a cleaning solution to clean the tip, but make sure the iron is unplugged first.
