I cut two 6 x6 pieces and glued them with a water resistant glue.
Attaching 2 plastic sheets.
Then apply heat again.
There are several ways to safely seal plastic sheets so nothing can seep through the seams but duct tape is a simple practical and inexpensive way to seal two or more plastic sheets for your home project.
Using the low setting on my heat gun gently heat up the two sheets till they get tacky.
Step 1 clean the two pieces of plastic to be epoxied together.
Attaching the second sheet step 1.
Covering objects step 1 repeat steps 2.
I am making a craft project.
Then immediately apply pressure to fuse them together allow to cool down if too hot.
When you finish remove the thumbtacks and fill in the holes with tiny dots of putty that match the ceiling color.
To join two plastic sheets the sheets can either be glued preferably with a good epoxy or fused together.
Plastic sheeting is notoriously hard to join tape is messy and glue won t stick.
Attach the plastic along the ceiling by pressing thumbtacks through it and into the ceiling at the rate of one every foot or so.
For lightweight plastic you may be able to use fewer tacks.
I need a glue that will hold water inside.
Rob shows a clip of plastic laminating where heat fuses plastic to paper.
Repeat sections 1 and 2 for as many sheets as necessary.
If the actual composition of the plastic is unknown an epoxy is the best choice as it will survive longer than the plastic sheets themselves.
