Creating a sand blasted sign involves 9 stages. All 9 stages will be expanded upon below, but you can also click each timestamp to be take to that part of the video.

Below we briefly explain each phase of the process of creating a custom sand blasted wood sign. You can view our custom crafted wooden signage page for example layouts and designs.

File preparation is an important phase of the design process, and generally includes laying out the design of the stencil in software like Adobe Illustrator or Corel Draw or Flexi Signs. From there you’ll be importing the design into plotting software which will plot out the design and get it ready for printing.
At this stage you’ll be using the plotter to cut the template for the sign-blank. We use a Roland plotter printer to cut the vinyl to the exact specifications of the intended design. The plotter enable us to get an accurate cut-line onto the HDU and trimming. The perimeter stencil is used temporarily and once you’re done using it on the sign-blank you can discard it.
At this stage you’ll also want to create the inside stencil design and have it plotted as well. This stencil will be used at the final sand-blasting stage.
This is the weeding stage which is where we remove all the excess material that we don’t need from the sign stencil. We start from the outside of the stencil and move inwards being very careful not to rip it, or the other necessary parts of the stencil, although the vinyl material is usually quite sturdy.
Once the excess material is removed from the stencil, we hand-balm the stencil onto the wood-blank or HDU and then trace the design using pencil, chalk or paint. In this example we dusted the stencil with spray paint because it’s much more accurate than using a pencil and saves a heap of time.
When hand-balming the vinyl, make sure to get the stencil as flat as you can and remove all air-pockets. Once you’ve traced out your lines and removed the vinyl, you’ll begin to see the wood sign edges starting to take shape.
This step is where you’d get your jigsaw tool out and start cutting around the edge of your stencil. The more practice at jigsaw cutting you have the more easier it will be to be accurate, but if you take your time, you can get it right the first time.
Simply just cut around the edge of your stencil along the marker you created (we used spray paint).
At this stage you’d sand and prime the surface of the template. Use low-grit sand paper to smooth the edges and surface, and then prime it and paint it. The primer gives the template a little more surface-strength and helps you identify any spots that need to be fixed or other minor imperfections.
To fix any imperfections, you can simply apply a body filler and then sand again, and when that’s done, give it one more coat of primer. Then add your final paint job with the selected base colour. When this stage is complete you move on to applying the blast stencil.
Pro Tip: for best results, let the paint on your template sit for at least 2 weeks before moving onto the next stage in order to allow all the gases from the paint and primer to escape and allows the paint to cure properly. This also hinders any paint from peeling off the template during the blasting process.
In this stage you will use a sand-blast imprint-stripping material that has the inner design cut out using our plotter printer, just like in the first stage. See the section of this document above titled Preparing the blast stencil.
Once your design-stencil is applied to the blank template, you’ll be ready to move onto the next stage where you begin to engrave the template using the actual sand-blast media.
This is the sand-blasting stage where you’ll be sand-blasting your stencil with blast media which will create a recessed look to your project. This gives your sign a really nice looking effect with shadows and depth and make it look like a genuine hand-carved sign with very high accuracy.
Once you’re finished sand-blasting your template, you can paint it to your specifications. Make sure to choose the right colours, and be as accurate as possible.
Your final product may not look as clean cut as this one but with time and practice you’d definitely refine your skills and be able to product a truly professional sand blasted sign just like this one.
