Instructions for using Quadra-Lock Interlocking Stencils
Quadra-Lock™ interlocking stencils are pre-spaced stencils cut like puzzle pieces. Just place the letters or numbers together and you are ready to start painting.
| Quadra-Lock™ stencils can be used in a standard horizontal method: | Quadra-Lock™ stencils can be used vertically: | Quadra-Lock™ stencils can used together to form perfectly spaced signs and markings for any surface. |
IMPORTANT INSTRUCTIONS
There are three ways to set up a stencil job using the Quadra-Lock™
Stencil system. If you will be using SPRAY PAINTS, PLEASE READ
THE FOLLOWING INFORMATION:
1. BASIC SET UP
Put letters and numbers together with spacers if needed. Spray on, brush on or roll on paints, inks or other mediums. Note: Spray applications often cause overspray in seams where stencils meet. Depending on your application, you may want to try the OVERLAP technique or SEAM TAPE method shown below under “Taping the Seams”.
2. OVERLAP
Quadra-Lock™ Stencils can be closely locked together by pushing stencils together so they overlap. The overlap method will push letters and numbers closer together and help prevent overspray in the seams. Please note that using this overlapping technique may cause some of the letters or numbers to raise slightly off the surface and overspray may occur. Depending on your application this may or may not be an issue.\
3. TAPING THE SEAMS
If your project requires zero tolerance for overspray, we suggest using painter’s tape to cover all seams where stencils and spacers meet. (show image) You may also want to use cardboard or newspaper and tape that to the edges of your project to prevent spray going onto other surfaces.
Quadra-Lock™ stencils ordered in sizes 8" - 36 will be laser cut on our white 60 mil material. This white 60 mil material is slightly more rigid than our 40 mil stock and is better suited for larger size letters and numbers. Sizes 7" or smaller will work fine with the 40 mil blue material. There are two ways to interlock these stencils together.
Using this 36” Letter Set we show how the stencils can be placed together using the standard “puzzle piece” format. Using a horizontal or vertical layout just fit the pieces together.
We still suggest using painters tape or cardboard around the edges
of the stencil if you are using an aerosol spray. This will prevent
unwanted overspray.
What Is Blank Mylar?
Blank mylar is a clear, flexible polyester film that's used as a stencil material across a wide range of industries and applications. It's durable, reusable, and holds a crisp, clean edge that transfers beautifully to almost any surface. Whether you're cutting your own designs by hand, with a craft cutting machine, or using it as an overlay material, a mylar craft sheet gives you a professional result that cardstock or paper can't match.
Because it's see-through, blank mylar also makes alignment easy, a huge plus when precision matters.
Why Order a Custom Size?
Standard sheet sizes work great for a lot of projects, but sometimes you need something a little different. Custom blank mylar sizing is a practical solution when:
- Your design is larger than a standard sheet
- You're cutting shapes in bulk and want to minimize waste
- You need long, continuous runs for borders or repeating patterns
- You're working with an industrial or commercial application that requires consistent, oversized material
- You want to match a specific substrate or format for production work
Whatever your reason, we're here to make it happen without any hassle.
The Applications Are Almost Endless
Our blank mylar custom-size sheets are used across a surprisingly wide range of projects. Here's just a small sample of what customers use them for:
- Home décor and DIY crafts: Create repeating wall patterns, furniture stencils, and decorative accents with a polished, store-bought look
- Sign making and lettering: Cut your own lettering stencils for wayfinding, retail displays, and event signage
- Pavement and floor marking: Thicker mylar holds up to repeated use on rough surfaces like concrete and asphalt
- Industrial labeling and safety marking: Used by facilities managers, warehouses, and plant operations teams who need reliable, reusable stencil material
- Screen printing and art projects: Mylar's smooth surface and dimensional stability make it a go-to for artists and printmakers
The clean lines you get from mylar are noticeably sharper than what you'd get from paper or acetate; it's one of those small upgrades that make your finished work look genuinely professional.
