The Hidden Secret to Better Water Control

Hi!

A lot of artists, even experienced ones, try watercolors only to find out it’s trickier than it looks 🙂

So just to reassure you:

it’s not you…

it’s not a lack of talent…

It’s just that watercolor has some unique characteristics that need to be learned! 

Luckily, these challenges are completely normal – and absolutely solvable.

After nearly 10 years of painting and teaching in watercolors, I’ve discovered there are some very common struggles that all artists face.

And “Water control” is the biggest frustration of all – no question.

But there’s one often overlooked factor that can make it a whole lot easier! 

In this lesson I’ll walk you through it step by step.

Water Control

If you’ve ever felt like water has a mind of its own, you’re not alone! Even now, I still get caught off guard by the occasional water control mishap.

You know the kind I mean – streaky washes, unpredictable blooms, or those moments when your paper suddenly turns into a mini swimming pool!

It’s no wonder, really. With watercolor, you’re essentially painting with water – which makes it very different from mediums like acrylic or oils. And that’s exactly why watercolors can feel so tricky – you need to understand how to work with the water, not against it, and how to control the water during the painting process.

Mastering this comes down to two key things:

• First, timing (because as the paper dries, the moisture level changes, affecting how much control you have over the paint).
• Second, the type of paper you use.

And this is where I think many watercolors beginners hit their first real stumbling block.

The type of paper you use actually has a huge impact on water control, especially when working with wet-on-wet techniques.

(And in case you don’t know, “wet-on-wet” simply means applying wet paint to a wet surface, and is one of the key techniques that makes watercolor so unique).

The longer you paint with watercolors, the more you’ll hear artists stress how important good-quality paper is!

To be honest, when I first got back into watercolors, I was a bit skeptical about this. How could paper make such a big difference?

But over time, I realised they were right 🙂

So if you’re struggling with water control issues – like watery stains, or streaky brush marks – the problem might not be your technique…

It could simply be your paper!

This is something my Masterclass students notice all the time.
For example, Ruth, one of my students, shared this after doing a paper comparison exercise:

“I did this exercise twice – once on student-grade paper and the other on Arches. The background on the student-grade paper was very streaky, but it blended beautifully on the Arches. What a difference!”

“Arches” is one of the best brands of artist-quality watercolor paper, and using it can make blending and achieving smooth washes much easier compared to lower-grade papers.

**Why Paper Matters More Than You Think**  

But why does the type of paper you use make such a big difference?  

It all comes down to how the paper is made…

Especially the way it’s “sized”

(“sizing” is the treatment applied to the paper to control how it absorbs water). 

Different papers handle water and paint in completely different ways, which is why some brands seem to make blending effortless while others leave you fighting against streaks and unwanted textures.  

To show you what I mean, let’s compare how brush marks behave on two different types of paper…

Artist vs. Student Grade Paper

Now… Not all watercolor paper is created equal. In fact, watercolor paper generally falls into two categories:

• Artist grade 
• Or student grade

Artist-grade paper is made from 100% cotton, while student-grade paper contains cheaper wood pulp. 

Cotton paper is stronger, more stable when wet, and absorbs water evenly – but it’s also more expensive and not as widely available. And the quality of its sizing is carefully balanced for watercolor painting.

Student-grade paper, on the other hand, is made from cheaper wood pulp and usually has inconsistent sizing… which means the water pretty much does whatever it wants! 😕

These differences in materials have a pretty big impact on how the paper handles water.

Let me show you what this actually looks like.

First, I tested Arches 100% cotton artist-grade paper. Then, I did the same on a popular student-grade, wood-based paper from Canson. To keep things fair, I mixed up the same puddle of paint to test on both.

First, I wet the Arches paper with clean water and painted the brush mark above. You can see how the pigment disperses smoothly, spreading in an even, and fairly controlled way.

Then I did the same thing on the student-grade paper. Right away, you’ll notice the difference. The paint doesn’t spread so evenly – it sits on the surface for longer, creating spidery edges, then suddenly absorbs in an unpredictable way, leaving a patchy appearance:

It’s all about how the water is absorbed, which depends on both the sizing and the type of materials in the paper.

Arches has high-quality internal and external sizing that helps paint flow beautifully. The student-grade paper, however, most likely has too much surface sizing or lower-quality ingredients, making it harder to get smooth, even blends with watercolor.

The problem is, artist grade paper can be pretty expensive! But luckily there are a few cheaper 100% cotton papers available on the market. The two that I have tried and like are:

• Ateza cold press 140lb/300 gsm paper (You can get a good deal on Amazon buying two pads)
• Meeden watercolor paper (A good solution for learning on cotton paper without paying the premium price).

These differences in paper quality are why I only recommend student-grade paper for sketches – not for paintings where you want to learn more control over water and blending.

If you’ve made it this far, you’re either seriously committed… or you really love talking about paper 🙂

But there’s so much more to explore when it comes to water control – and I’ve got you covered in my full course…

In my Watercolor Masterclass, you’ll learn everything from choosing the right paper to mastering wet-on-wet techniques, controlling brushstrokes, and perfecting blending.

With over 50 lessons, this course offers guided, step-by-step learning that you can go through at your own pace. It’s designed to help you build confidence and skills gradually, with plenty of support along the way – from me! I’m here to help whenever you need it!

So if you’re ready to stop fighting with your water and start making it your ally, I’d love to see you in the full course!
