Watercolour Canvas — Re-Erasable PET, No Glass | ACF

Watercolour Canvas — Re-Erasable PET, No Glass | ACF

The brush moves across the surface the way it would across good paper. Pigment pools, lifts, reworks — and keeps reworking, where paper would have started breaking down after four washes. No chalky ground cracking underneath. No shrinkage when the wash dries. No glass needed to frame the finished piece behind. 240gsm 100% PET with a proprietary watercolour coating, refined through seven iterations. What watercolour on canvas was always meant to be.

"I have been using ACFCANVASSES for a while now. I highly recommend all artists who have not yet experienced them to give them a try. You will be truly impressed with them, and the quality is superior to other makes of canvas on the market."

Watercolour without the workarounds.

  • Lift and rework where paper would have started giving way after four washes
  • Wet, dry, repeat - no shrinkage, no expansion, no wrinkling under the wash
  • Hang the finished piece without glass - gallery-ready as soon as the paint dries
  • Sharper, cleaner finish than paper — no fibres breaking down, no colour dulling on drying

What our watercolour coating changes.

  • Conventional watercolour-on-canvas requires a chalky absorbent ground that cracks underneath the wash. Our coating eliminates the workaround.
  • Paper degrades after about four washes. The PET substrate doesn't break down — lift and rework as many times as the work requires.
  • The coating is ours. Refined through seven iterations and validated by working watercolour artists, including RSMA member Mark Buck.
  • Manufactured end-to-end in our own factory — proprietary fabric, proprietary coating, proprietary strainer.
  • Polyester durability has been independently studied: the Victoria & Albert Museum found no measurable loss of strength under museum conditions equivalent to 80 years of display.

Tired of taping stretching and buckling

  • Watercolour paper that starts breaking down after about four washes - limiting how much you can lift and rework
  • Paper cockling, shrinking, or wrinkling the moment a wash gets too wet
  • Gluing paper down to stop it moving the moment water hits it
  • Watercolour grounds on canvas that crack, run off, or feel like the paint will rub away once dry
  • Framing every finished watercolour behind glass - adding weight, glare, framing cost, and a framing trip

Watercolour Paper vs ACF Watercolour Canvas

  • Traditional canvas

    • Degrades after about four washes - limiting how much you can lift and rework
    • Cockles, shrinks, or wrinkles whenever a wash gets too wet
    • Needs stretching, taping, or gluing to stay flat under water
    • Colours often dry two shades lighter as the paper absorbs pigment
    • Must be framed behind glass - adds weight, glare, framing cost

  • ACF Watercolour Canvas

    • PET substrate doesn't break down - lift and rework as many times as the work requires
    • No shrinkage, no expansion, no wrinkling under the wash
    • Taut on the frame from the start - no prep needed before painting
    • Colour stays where you put it - no two-shade fade on drying
    • No glass needed to frame - finished work hangs gallery-ready

Questions artists ask

Do I need to prime or gesso this canvas before painting?

No. The canvas arrives pre-coated with our proprietary watercolour coating, engineered to be painted on directly — adding gesso, ground, or any other coating disrupts the surface. Treat it like premium watercolour paper: handle the edges, not the face, since skin oils can mark the coated surface.

Will it shrink, wrinkle, or distort when wet?

No. The substrate is 100% PET (polyester), which doesn't react to water the way paper or cellulose fibres do — no cockling, no shrinkage, no expansion under a wash. The fabric stays taut on the MDF strainer from the first stroke onwards. Independent research at the Victoria & Albert Museum found polyester showed no measurable loss of strength under museum conditions equivalent to 80 years of display.

What paints can I use on the Watercolour Canvas?

Watercolour is what it's built for. Watered-down acrylics and gouache also perform well on the coated surface. The coating eliminates the chalky watercolour-ground workaround that conventional watercolour-on-canvas relies on — pigment spreads, lifts, and reworks the way it would on premium paper. TIP: As Mark Buck RSMA observed, the surface takes a slightly thicker pigment mix beautifully — go heavier on the paint than you would on paper.

How many canvases come in a pack, and what sizes are available?

Watercolour Canvas is sold in packs of 2. Currently available in A4, A3, and A2 — with additional sizes added as demand grows. Every canvas in the pack is matched in tension, surface, and coating.
