I have made many murals. I would use acetate first to trace the logo
and the other information. Use a Sharpie pen.
The size of the drawing should be about 5x7.
You are going to put this on an overhead projector and project the
images on the wall. You will trace these with a Sharpie right on
the wall, also.
Then you can paint in the image using acrylic paints. Use good
quality paints. Wash and prime the wall before you paint and finish
with a coat of acrylic varnish (non-yellowing). Let the paint set up
three weeks before you varnish. After you varnish, wait a few weeks
again and try washing a small area of the mural to see how well it
will withstand cleaning. Weak ivory soap and water with a soft
cloth should work well.
Before you start the project, you (the teacher) should do a tryout
to be sure the system described to transfer the image to the wall
will work. It will be best if you have a good sized space where you
have room to enlarge the image enough on the wall. A foyer is best.
Draw a simple shape and see how the overhead projects it. How close
do you have to come to the wall? How far back can you go? Trouble
How many students? I usually have a couple at a time. Be careful if
they have to climb. this is a safety issue. The safest is to have
an actual scaffolding, but if not, risers can work. No chairs on
top of desks, no ladders. You should check with your maintenance
workers and your principal or AP what system will work for you.
Don't proceed if the safety issues are not worked out.
Another safety issue is passing times. Painting should stop
completely if students are passing through the area during a change
Mess is not a problem if you give the paint out in small containers
with lids. Students planning to paint should be wearing clothing
that is not precious, or they should wear coverings. I use large
trash bags and ask students to wear short sleeves.
Accidents can happen, but if you explain that the paint is indelible
- permanent, students are usually very careful.
If you have many students you can divide the numbers by task.
Everyone will want to paint, but you need to find out who can paint
carefully and slowly so no do-overs. You will probably need two or
three coats of paint for a rich and permanent finish, so you will
probably have enough work to include all your students.
If the wall is cement block, I like to paint a background color, as
well as the main images.
It's important that you control the project. Too many painters at
once can get chaotic. But everyone should have a chance!
If this works, you might be able to paint other kinds of murals.
Murals are great. What an opportunity you have.
