I would like to close up my a/c for winter. I have the insulation and plastic but do not know how to attach it to my cement walls. Cellophane tape, duct tape, electric tape and masking tape have all proved to fail (and pretty quickly too). Any suggestions from you wonderful Yahoo people? I would be grateful.
Why do you have to attach it to the cement wall. These products are made to just enclose the unit which is all you need.
If the cement is dry, dry brush it briskly and apply a 2 strip of double sided tape like they use for carpets. The other choice is to use that Velcro tape. It comes in a roll in a dispenser. It has tremendous holding power. A third choice would be to drill some 3/16 plastic plug holes, then drill a matching piece of 1x2. The 1x2's will hold the plastic in place when you screw the wood to the cement wall. Hope this helps.
Liquid Nails would hold it, or a similar adhesive, which you might find in different colors.
