Essential mural tips and
techniques
My question is" I am doing an approx.
3'x4' wall painting and am wondering
if it can be done on canvas, then
removed from the wall in a few years
and saved? Would I stretch the canvas
on a wooden frame, prime and paint it,
then cut the dry painting from the
frame and glue to wall? Is it then
possible to blend the edges enough to
make it look like it is actually
painted on the wall? Or, is there a
better technique?"
You can apply a canvas to a
wall, and remove it later. There are a
couple different ways you can approach
this process.
Using pre-primed canvas - If
you use pre-primed canvas that is not
already stretched on a canvas frame,
then you can apply the canvas directly
to the wall and paint on it after
installation. If it is already
stretched, then paint your picture,
remove it from the frame and install
the completed work on your wall
surface.
Using un-primed canvas – If
you are using un-primed canvas then it
is best to purchase a pre-stretched
canvas on the frame, or stretch the
canvas yourself, and then prime the
surface. Follow the tutorial for ‘stretching
canvases’ on this site for more
details.
Removing the canvas from a frame
– Once you have completed your
painting you will need to remove it
from the frame. You can do this in 2
ways. The first, and recommended
method, is to remove the canvas
completely from the frame by removing
the staples. Then cut the excess
canvas with scissors, or a sharp razor
and metal ruler, to the size you want.
The second method is to cut the canvas
directly off the frame using a sharp
razor blade.
Mounting the canvas to the wall
– The objective is to hang a painted
canvas on a wall surface and be able
to remove the canvas at a future date.
You will need to use glue to mount the
canvas. The most common glue for this
purpose is ‘Jade Glue’ found at most
art supply stores. It is a white glue
and can be thinned slightly for easier
application.
Experiment first - You
should try gluing a piece of scrap,
primed canvas to a wall (scrap wall
board – or inside a closet) to
understand the adhesion and mounting
requirements. Spread the glue in a
thin, even layer over the entire back
surface of the canvas then apply to
the wall, working any wrinkles out
with a large plastic blade. It is best
to use the blade over a piece of craft
paper, or similar, so you don’t
disturb the painting. Be sure the
painting is completely dry, especially
if you are using oil paint. The
mounting of the canvas will be a bit
trickier if there is a noticeable
texture created during the painting
process.
Another option is to use wall paper
paste. There are a few different
grades of paste. Talk to a
professional wall paper hanger if you
have any questions about specific
products.
Canvas edges – Depending on
the thickness of your canvas you will
have a slight edge that remains from
the canvas to the wall. You can over
come this by attaching a frame
directly to the wall, simulating a
hanging piece of art. Also, once the
painting is mounted and dry you can
continue the painting onto the wall
surface, diminishing the visual edge
line by floating or softening out the
picture.
