Taping down and the buckled-paper truth

Paper is behind us; today we wet a sheet and watch it misbehave. Before we do, we need to cover tape, because tape is where people go either overconfident or too scared — and both cause problems.

Start with what will happen: paper under 140lb buckles when it gets wet. Not might. Will. Water swells the fibers, the sheet stretches unevenly, and unless you're using something heavier or you've properly stretched it ahead of time, you get waves — little hills and valleys across the page. It looks alarming the first time. It is not a disaster.

Why we tape at all

Taping does two things:

  • It holds the paper still so it doesn't slide around while you're working.
  • It gives you a clean edge when you peel it off at the end — a nice crisp white border like a little frame. That alone is satisfying and worth doing.

What taping does not do, at least with regular painter's tape on regular paper, is stop the buckling completely. I want that clear now so you're not disappointed later.

How to actually tape a sheet down

  1. Lay your paper on a board — cheap foam core, plywood, whatever's flat and bigger than the paper. I use a scrap of foam core I got from Macey's, nothing special.
  2. Run painter's tape along all four edges, about half the width of the tape on the paper, half on the board. Press it down firm with your thumbnail or the back of a spoon, especially the corners.
  3. Don't stretch the paper tight like a drum. Just secure, not tense. You're not upholstering a chair.
  4. Let it sit a second before you touch water to it. No real reason except it makes you slow down, which is good for you.

Once you've done it a few times, it takes two minutes.

The buckled-paper truth

Here's the honest, slightly embarrassing history behind all this. My very first wash ever, before I knew anything, I used regular printer paper — not watercolor paper, just what I had in the house, because I was too impatient to go buy real supplies. I loaded up my brush, put water down, and the whole sheet warped into a potato-chip shape almost instantly, like it had a personality of its own. It curled at the corners, it had ridges in the middle, it looked nothing like paper anymore.

The next time, I bought actual watercolor paper and taped it down properly, feeling very smug about having learned my lesson. It still buckled. Not as dramatically, but it did, and I remember being kind of annoyed — like, I did the thing, why is it still doing the thing. Eventually I just decided buckled paper was going to be part of my personality as a painter and stopped fighting it. For a beginner it doesn't matter much: a little wave in the paper doesn't ruin a wash. It mostly matters if you're framing something under glass later, and at this stage you are not framing anything. You're learning.

This is also why I tell every beginner to buy the cheap paper first. I didn't. I went and spent forty dollars on nice artist-grade cotton paper before I could even lay down a wash that didn't look like a puddle of regret. Big mistake — I was scared to touch it because it was expensive, so I barely used it, so I learned nothing faster than if I'd just bought the cheap stuff and ruined twenty sheets of it. Cheap paper first. Ruin a lot of it. That's genuinely my advice, not just a bit.

A real caution, quickly

Painter's tape can pull the surface fibers off cheaper paper when you peel it, especially if the paper's still even a little damp. Let your painting dry completely — a full hour at least here, given how fast things dry in this air — before you take the tape off. Peel slow, pulling the tape back on itself at a low angle rather than straight up. If it's fighting you, stop and let it dry more.

Before next time

Grab your cheap paper, your board, and a roll of painter's tape if you don't already have one, and get one sheet taped down at home so it's ready to go. Don't wet it yet. Just get comfortable with the taping part so next lesson we can jump straight to water.
