You’ve just bought your new painting canvas. Ready to paint a masterpiece when suddenly you come across 8 small pieces of wood<\/strong> behind your painting.<\/p>\n

At the time, I was the first to say to myself, “What the hell<\/em> is this?<\/p>\n

This “trick” is called a chassis wrench, and it’s the key to a beautiful, sturdy chassis that will age well.<\/p>\n

What is a frame wrench?<\/h2>\n

Chassis wrenches<\/strong>give your painting an optimally stretched canvas.<\/p>\n

In fact, many canvases are slack at the time of purchase, and the use of wrenches will enable the canvases to be correctly tensioned.<\/p>\n

A well-stretched canvas will ensure that your painting ages well over time. It is also possible for a canvas to relax over time. This is due to a number of factors, but in particular to changes in temperature over the different seasons and years.<\/p>\n

How to stretch a web with keys<\/h2>\n

You will find below the video demonstration where I show you how to stretch a canvas with the keys. I recommend you watch it.<\/p>\n

Here’s how it works:<\/strong><\/p>\n

    \n
  • Detach the small package containing the various keys (in most cases, you’ll have 8 pieces of wood).<\/li>\n
  • Place the 8 keys in the slots in each corner of the frame, there are 2 slots per corner (see video).<\/li>\n
  • Then tap each key lightly with a hammer (two to three light blows per key), move on to the next key and continue cyclically until the canvas is optimally tensioned.<\/li>\n
  • To check that your canvas is correctly stretched, you can regularly tap it with your finger and listen to the sound it makes.<\/li>\n
  • Caution: Under no circumstances should you overstretch your canvas, as this would have a detrimental effect on your stretcher and risk twisting your painting.<\/li>\n<\/ul>\n

    And here’s the video on how to use the keys on your board.
