To use, cut or fold the blackout sheet to fit the window (glass or frame), apply the double-sided tape to the sheet, peel away the backing tape to reveal the repositionable adhesive and place your blackout against the window.
Thin, flexible, lightweight and extremely effective. For larger windows, two blackout sheets can be overlapped.
The repositionable adhesive can be used a number of times. Between uses, we recommend replacing the backing tape to protect the adhesive until the next use. It is also possible to fold the tape over so that it sticks to the blackout sheet until the next use. When the tape looses it's effectiveness, simply replace it from the 50m roll included in each kit.
For even faster blackout, blu tack (not supplied) is very effective for use with this plastic blackout sheet.
