When you work in a school, you will need to ensure that the communal area conforms to certain codes. This will relate to everything from the number of fire extinguishers to the signs on the walls.

However, in relation to the latter, it can get costly to have a set of signs made, so many schools opt instead to use stencils to mark key areas around the school or even stickers.

Applying stickers is pretty straightforward (you just stick them to the wall!), but it can be a bit of a headscratcher to figure out how to apply stencils correctly. So, here is a simple step-by-step process to guide you through stencil application to the interior walls of your school.

Choose The Stencil Material and Agent

If you want to apply the stencil similar to a fire exit sign to a wall that has eggshell paint on it, you are going to need a specific type of paint or agent to pull this off, as well as ensure that the stencil is made from the right material so it will not bleed or warp.

So, if you need a bit of help choosing the right material and paint, head to for more information.

Clean The Area

Many people are surprised at how much dirt can accumulate on a wall, so before you do anything else, clean the surface thoroughly to remove any dirt, dust, or debris.

If you scrub a bit vigorously and remove some of the paint, it may be worth reapplying a coat before putting the stencil on the wall. This will help to ensure that the area is clean and will also help the stencil to stand out.

Sand The Surface

This only applies if the paint is glossy and as before, you will need to be very careful not to remove the layer of paint.

So, use the lightest sandpaper and apply it to the surface lightly. This will create a rough surface for the stencil to adhere to, and will, once again, boost the chances of the stencil standing out.

Prime The Surface

Prime the surface with a sealer or primer specifically designed for the type of surface you are working on, and, preferably, use a primer that will work alongside stencils and the paint that you want to apply the stencil with. This will help the stencil paint adhere to the surface and prevent bleeding underneath the stencil., creating blurred lines.


Now, you need to wait at least 24 hours to ensure that the surface is dry before you put the stencil onto it. You may need to wait longer if the paint has a slight gloss or if it is in a location where there is a lot of moisture in the air.

Apply The Stencil

The moment of truth! Now the surface is ready for stenciling, and you can now apply the stencil and it should stick. If you are using a stencil with paint, be careful not to smear it, and take your time for a professional finish.
