Use a stencil adhesive for flawless results.
When inexperienced amateurs attempt to paint with stencils, the paint often bleeds under and through, causing damage to underlying surfaces. Combat this problem by using impermeable stencils made of plastic or vinyl. Use a special low-tack adhesive, specifically designed for stencils, or you may end up with flawed results. Apply the paint in a specific manner, or the finish may pool and sag.
Instructions
1. Place the vinyl or plastic stencil facedown on a strip of cardboard.
2. Apply stencil spray adhesive to the back of the stencil.
3. Affix the stencil to the area where you want the letter, shape or number to appear. Apply painter's tape to the edges of the stencil for extra security.
4. Coat the exposed letter, shape or number within the stencil with spray paint. Maintain an 8-inch distance between the exposed area and the spray nozzle as you apply. Wait one hour before removing the stencil.
