Frequently Asked Questions
What surfaces do these stencils work on?
The oil board construction resists paint bleed-through on most smooth to mildly textured surfaces — cardboard, wood, concrete block, and paper all work well. Heavily porous or irregular surfaces like rough brick or unfinished lumber may require slower paint application to prevent bleeding under the stencil edges.
How durable is the oil board material through repeated use?
Oil board is more durable than plain cardboard stencils but will eventually soften if soaked repeatedly in paint or cleaning solvents. Wiping the stencils clean after each use and letting them dry flat extends their lifespan considerably — with moderate care, these handle dozens of applications before the edges lose definition.
What paint types are compatible with these stencils?
Spray paint, brush-applied latex, and oil-based paints all work. Spray paint at medium distance gives the cleanest edges. Thick brush-applied paint can seep under the stencil if applied with too much pressure — use a stippling or dabbing motion rather than dragging strokes.
Are all characters individual stencils, or are multiple characters on the same sheet?
Each character is a separate stencil piece. The kit includes the full A–Z alphabet, numerals 0–9, and common punctuation symbols as individual boards, which allows you to arrange any combination without the other characters getting in the way.
Is the 10-inch size appropriate for shipping boxes and outdoor signage?
At 10 inches, these produce lettering that is clearly legible from several feet away — well suited for shipping and warehouse box labeling, yard signs, and project boards. For smaller applications like binders or craft projects, the size may feel oversized; for large outdoor signage visible from a distance, the 10-inch characters may be smaller than needed.
