How To Mount a Stamp Using Mounting Foam

Unmounted rubber stamps need to be mounted prior to use. The use of mounting foam allows the unmounted rubber stamps to be used with acrylic blocks. This combines many of the features of a wood mounted stamp with the ease of use and convenience of clear polymer stamps.

Mounting foam products are coated on one side with a strong adhesive that adheres to the back of the stamp, with the other side being lightly clinging which will hold the stamp tight to an acrylic block, yet allowing it to be easily removed and repositioned.
Difficulty: Easy
Time Required: Quick

Here's How:

  1. If you have never worked with mounting foam take a moment before starting to familiarize yourself with the product. Gently lift off the protective paper a tiny amount in the corner and compare the two sides. One will be extremely sticky and this is will permanently stick to the stamp, the other is clingy and will adhere to the acrylic block.

    The adhesive is extremely strong so take care when using, particularly to ensure that no small bits of discarded foam become stuck to you or any of your work that maybe nearby.

  2. Ensure that the smooth side of the rubber stamp is clean and free from dirt, dust or grease and is completely dry. This will help the stamp to make a permanent bond with the adhesive.

  3. The first step of the process is to stick the stamp to the adhesive side of the foam. This will stick it in position permanently so choose carefully where you want it to go on the foam. As you will be cutting into the foam sheet it makes sense to stick the stamp in one corner to eliminate the need to waste the foam by cutting needlessly into it.

  4. Peel back the protective paper from the adhesive side of the foam, just revealing enough space to place the stamp. Firmly place the stamp in position.

  5. Roughly cut around the stamp to remove it from the sheet.

  6. Carefully snip around the stamp, snipping as close as possible to the stamp, but be careful not to cut under the stamp as this will result in unclear images.

  7. Remove the remaining piece of protective paper from the stamp and press it to an acrylic block and the stamp is ready to use!

  8. To clean, wash the stamp in water or use a stamp cleaner. Do not leave the stamp to soak in water. To store the stamps keep them in a clear plastic wallet, or stick to a sheet of plastic. This will help protect the stamp and keep the clingy side clean and clear from dust.


  1. Use a stamp with a simple shape to start with as this gives you the opportunity to get the feel of cutting the foam before moving on to more intricate shapes.
  2. Scissors with short sharp blades are the best for cutting rubber. There are special rubber cutting scissors available such as Kai scissors. A craft knife also works well, allowing small shapes to be cut with relative ease.
  3. Keep a sheet of scrap or scratch paper to hand to stick any odds and ends of foam onto. This will stop them from falling on the floor or attaching themselves to unwanted items.
  4. Maximize the amount of stamps that you can mount from a single sheet of foam by placing stamps carefully to eliminate waste.
  5. It is possible to place a whole sheet of uncut stamps onto the mounting foam, cutting the stamps and the foam together. Before doing this, however, ensure that the stamps are efficiently laid out on the stamp sheet to avoid wasting any foam. It might be better to cut the stamps out first and place them on the foam as required.
