Our safetly treads help to prevent slipping in a bath or shower. They are self adhesive, easy to apply and available as strips (20 x 200mm each) or as discs. Please Note: The surface you are applying the stickers to, must first be cleaned with an alcohol based cleaner, to ensure no residue is left, creating a good adhesive bond between disc and surface. Using any cream cleaners will leave a powder residue, which will contaminate the adhesive and cause it to fail.
