This comes in a bottle with a brush and you should paint a light coat of the glue around the stoma. This should cover all of the area where the plastic housing will be. Be very careful not to touch this area or couch once the glue has been applied, as this will lessen the chances for a good seal. After this had dried, you are ready to apply the housing. A double-sided adhesive tape disc is applied to the plastic housing and this is then applied to the neck.
Some people also use adhesive foam discs.
The hole in the housing should match up with your stoma. The housing should be firmly attached to the skin and pressure should be applies to make sure all air bubbles are worked out of the glue. If you decide to use the adhesive foam discs, you might want to first layer the housing with an adhesive tape disc and then put an adhesive foam disc over that so that when you are eventually pulling everything off the housing, it will be easier to remove. Read the information found in the instruction manual that came with your original Tracheostoma valve kit. As you learn to control the amount of air pressure in the stoma area, you can start to use less and less of the liquid silicone adhesive.
