How to Stencil With Spackling Paste
- 1). Create a stencil shape by cutting a design out of thick cardboard with scissors or a utility knife, or buy a stencil from a craft store.
- 2). Mix the spackle according to the manufacturer's directions. Typically, ready-mixed joint compound only requires gentle stirring, but setting-type joint compound requires you to add clean water to the powder to achieve the proper consistency.
- 3). Hold the stencil flat against the surface you are stenciling.
- 4). Use a drywall knife to apply a smooth, even layer of joint compound across the stencil. Choose a knife that is wider than the stenciled design to minimize lines from wiping. For example, if the stenciled shape is 5 inches wide, use a 6-inch drywall knife.
- 5). Peel the stencil away. Move slowly and carefully to avoid smudging the design.
- 6). Allow the compound to dry according to the manufacturer's directions.
- 7). Sand the design gently with 150-grit sandpaper if there are any surface flaws or lines.
