Reusable Stencils are made for outdoor use, however with the right supplies, they can also be used indoors.
The Reusable Stencils are typically used outdoors on pavement, and are designed with that intended use in mind. However, the stencils are like templates and can be used indoors as well. If you choose to use the stencils indoors, we recommend using a different paint that is compatible with your surface(s). It is best in this case to seek advice from a professional painter and your local Sherwin-Williams store as to the best paint for your particular surface material.
