Unmounting a rubber stamp from a wood block is a process that can be completed within several minutes. In order to unmount a stamp, you will need scissors, a microwave, an X-Acto knife, a sponge brush, an adhesive foam sheet and vinyl sheets.
Microwave and remove wooden base
Place your stamp inside of the microwave and turn it on for about 5 seconds. Once you have removed the stamp from the microwave, you can take it off of the wooden base with your fingernails. Pull carefully so that the back of the stamp is smooth.
Trim the rubber
With your scissors, roughly trim the rubber of the stamps and cut away anything that is not relevant to the image. This will reduce the amount of work you need to do later and help save space.
Stick the stamp to the vinyl sheet
Press the back of your stamp against the adhesive foam sheet. Stick the adhesive sheet to the non-clinging side of the vinyl sheet.
Trim the edges
Using the X-Acto knife, cut carefully around the edges of the stamp. The stamp should be smooth on all sides so it can be used as a clear stamp or attached to another base.
