Porous surfaces are used to refer to the type of surfaces that contain pores (small empty spaces), allowing certain elements like water, air or dust particles to seep in through, penetrating their outer layer. Some materials that contain porous surfaces are paper, wood, sponge, fabric and more! Because of the spaces in between the material, stamping a crisp clean image with your rubber stamps can be difficult, especially when you are dealing with slow drying ink.
If you intend on combining rubber stamps with materials that contain porous surfaces, you will need to take the time to prepare your material in certain ways so as to minimise the ink seeping or smudging. Here’s what you need to do:
Test out your rubber stamps on scrap pieces or leftover pieces of the material you want to rubber stamp on- if the ink runs or seeps into the material, it would be good to seal the material’s surface first by either painting on a protective coating or other paint material so that you will have a better background to place your rubber stamps on.
Consult your rubber stamp supplier and ask for recommendations on the coating you can make use of before rubber stamping, make sure to let them know the material you are using so they can choose the right primer based on your requirements.
To apply the coating, a brayer style rubber stamp is recommended so that the coating can be evenly spread. Experiment with the layer of protective coating that is needed so that you will be able to produce the best results. Clean the material you wish to place your rubber stamps on and make sure that the surface is completely dry before you begin rubber stamping again.
Once you have successfully completed this step, you should be able to apply your rubber stamps on the material as per usual. However, take note that if you are using slow drying ink for your rubber stamps, you may want to give it a moment to dry completely again before resuming the stamping process. Once it is done, the final result of your rubber stamped image should be clean and crisp on the material.
If you need additional steps like colouring your rubber stamped images, then you can either combine your rubber stamped images with markers or dry colouring material like chalk before sealing with varnish to protect the appearance of your results.
