How to Paint a Mural on the Wall

Updated February 21, 2017

Unless you are blessed with considerable artistic talent, you will probably find it nearly impossible to create a wall mural without a guide. Fortunately, even the least artistic, amateur do-it-yourselfers can paint a mural if they know the proper techniques to employ. Most wall murals are created with the help of a projector, used to cast an image onto the wall. Using this image as a guide, even inexperienced painters can create sharp, professional-looking murals.

Abrade walls consisting of plastic, vinyl or fibreglass panelling by scouring them with sandpaper. Do not abrade wood or drywall.

Apply acrylic latex primer to plastic, vinyl, wood and fibreglass panelled walls, using a roller. Wait two hours for the walls to dry. Do not prime drywall.

Take a photograph to a film-processing store. Have it converted into a slide.

Insert the image into the projector. Point the unit so it casts the image in the area where you want the mural to appear.

Cover the floor beneath the wall with dropcloths.

Paint the mural using the projected image as a guide. Use an acrylic spray paint to coat larger, background areas and craft brushes to paint smaller, detailed areas.


Do not paint a mural on plastic, vinyl or fibreglass panelled walls without abrading them, first, or the mural will peel.
