Canvas Preparation

by Logan Ransley June 26, 2018

Sometimes wrinkling can be normal for shipping canvases like ours, so if your Paint By Numbers canvas has arrived slightly wrinkled, we've got two methods you can try to flatten the piece.

With both methods you’ll want to get the entire back of the canvas damp, and then let it dry at a uniform rate. Both methods use an approach that will not affect the front painted image.

For each of the approaches below, extreme care must be taken to make sure the water used to soften the back of the canvas doesn’t travel through the canvas and dissolve the print on the front side. 

APPROACH A:

Step 1

Mist the back of the canvas with water using a fine mist. You can also use a damp sponge. Do not over wet.

Step 2
Place newsprint paper down on a clean surface. The newsprint should be larger than the canvas.

Step 3

Place the canvas image-side down on the newsprint paper.

Step 4

Cover with another sheet of newsprint or a towel. Place a board over the newsprint paper that is larger than the canvas. 

Step 5

Put weights on top (you can use books if you don’t have weights).

Remove the board and weight every 2 hours and replace damp newsprint with dry newsprint. Repeat this until the newsprint is not wrinkling or does not feel damp, usually around 4-6 cycles. Then put another new dry sheet of newsprint down and cover with the board and weight. Leave 24-72 hours until paper is completely dry.

APPROACH B:

This approach is a more drastic solution that uses heat (an iron) with water to help relax the canvas fibers. If you have never used an iron to relax the canvas fibers before, a test should be done as this approach can ruin the canvas if the iron is too hot or if it sits on the canvas too long.

Step 1
Mist the back of the canvas with water using a fine mist. You can also use a damp sponge. Do not over wet.

Step 2
Place newsprint paper down on a clean surface. The newsprint should be larger than the painted paper.

Step 3

Place the canvas image-side down on the newsprint paper.

Step 4

Cover canvas with a sheet of newsprint or a towel.

Step 5

Using an iron set on medium low, gently rub over the entire surface. Adjust heat up as needed to allow the dampness on the back of the paper to relax the canvas fibers.

Step 6

Remove the towel or damp newsprint and replace with a fresh piece of newsprint over the canvas.

Step 7
Put weights on top (you can use books if you don’t have weights).
Remove the board and weight every 2 hours and replace damp newsprint with dry newsprint. Repeat this until the newsprint is not wrinkling or does not feel damp, usually around 4-6 cycles. Then put another new dry sheet of newsprint down and cover with the board and weight. Leave 24-72 hours until canvas is completely dry.
