How to Fix a Warped Cutting Mat

NSC Question

Help! My cutting mat is buckled up and warped on one side now when it got accidentally too close to some heat. I paid $50 for this mat. I laid some heavy old machines on it for days to see if it would force the mat to return to its original flat surface, but no go. What should I do?

Oh no! Not what you want to have happen to your expensive cutting mats! But I think there is a solution here – this might seem counter-intuitive but one way to get a mat to lay flat again is to add back a little heat. This will soften it down and then you can try setting something heavy on it to get it to retain its flat surface. I’m not sure where you live, but if you are in a sunny area you can lay the mat out on a porch or deck to warm for an afternoon and then stack something heavy on it to get it to lay flat again.

Good luck!

    You might also try submerging your mat in very hot water (in the bathtub). Leave it in the tub to soften, then take it out and place some bricks or very heavy books (wrapped in plastic) on it and let it cool. If you have a tile floor in your bathroom, place it there. Dry it off after it flattens. It may need more than one dunking in very hot water.

    I looked online and found this: use your iron! Yes – your iron! Heat up the mat with a protective presscloth then lay it on a flat surface with books weighting it down. Leave it for at least 12 hours or so. It worked and my mat looks great.

    I tried that on mine – but it didn’t help – though maybe I didn’t heat it enough. Maybe putting it in very hot water might be safer than ironing over it again. It would be easier to control the heat I think. Fortunately I already had an extra mat that I found at a yard sale. ($4 !!!)
