I've run into a lot of problems with uneven wet washes, splotchy absorption or white speckled dots where watercolor paint will not sink into the surface coating (sizing) of the paper. It appears that Arches cold press cotton watercolor paper has been having an increased rate of sizing failure in 2020-2021. It is possible that during the pandemic supply shortages something changed with their core ingredients to make this paper more susceptible to this issue.

Thank you for this blog. I have painted with Arches, full sheet 22 X 30, 300 and 400 pound papers for many years, always with good results. About 3 years ago I had purchased 5 sheets of 400 pound cold paper and had problems with the way it absorbed the pigments. The problem showed up when using washes in backgrounds, they would not absorb evenly, and puddled and left a line, in a place where I did not want one. I lost several good paintings with this problem, it was very frustrating. Sometimes I could work around the problem, but it took a lot of time and effort, and some unwanted experimentation. I emailed Arches several times, but never had a response. This blog helps me get a better understanding of the problem. I hope this a temporary Arches problem, the paper was outstanding and very fine.

I am so glad to have read all these comments. I have almost given up on painting with .
watercolour for the very same reasons. All the paper I have which seemed to have worked before just acts like blotting paper. I am totally fed up and maybe should stick to acrylics!

Dang. I read the comments. I have been having awful results with the Arches 140lb coldpressed the last few years. I thought it was me. Glad to know it isn’t, but I want my old Arches back. My work is crap without it.

I’ve been having the white speckling issue A LOT lately with expensive cold pressed paper. A new pad of Arches, a new block of Lanaquarelle, a block of Baohong, sample sheets of various other brands.. The paint looks ok when wet and then as it dries it turns chalky and the speckles appear. It also causes edges to look very jagged. It’s extremely frustrating when an entire block is unusable. What is going on with the sizing these days?

Purchased my 300# Arches in May. 20″ × 30″ (2 sheets) and 4 other sheets about 1/2 that size. Cut my 20″ × 30″ down. Spent all of Ian hurricane tracing my beautiful peony that I planned to paint with a tutorial. (I was saving my paper for a “special project” I loved. Water on plain white area . . . soaked right through to the back. Looked like holes in a sponge. I couldn’t tell how much paint I was laying down as these speckles were so dark in color. I’m so upset. Notified Dick Blick. Another gal in the class was experiencing the same issue with her 300# Arches. This was the first time for both of us to invest in such an expensive paper to paint with. Urrrrr

I bought and used Arches watercolor CP 100% cotton paper for the first time this summer. I have been very disappointed with the way my watercolor paint looks or behaves on it. I am also very surprised because everyone praises Arches paper. I will not be buying this brand again.

I just got a large sheet and it immediately absorbs any water and pigment . It almost makes my watercolor pigments behave like ink. It stays where it is laid down and absolutely no blending or lifting possible. I’ve had arches paper that has gone bad before and it definitely speckles. But this is nothing like I’ve never seen before . Worst part is I used that sheet for a leather bound sketch book . 🙁

I’ve been having bad issues with Arches and the sizing actually lifting and mixing into my watercolors causing a muddy dull look. I switched to new brand and have had NO issues. It’s really upsetting when I’ve just purchased a couple pads and full sheets…what a waist and very disappointing.

My brand new Arches CP looks exactly like this! I’m glad I found this article because I’m a beginner and it’s my first time using Arches so I didn’t know what to expect. Which I didn’t like and it’s disappointing because I’ve only heard good things about them. I also get jaggy edges when I paint wet on dry, is it also due to bad sizing? It’s like when it’s wet it looks like a straight smooth line but as it gets dry it starts getting rough and jaggy. I’ll try the gum arabic strategy and see how it goes.

I too have been noticing my 140lb cp paper is not handling watercolor paint well. On a recent painting, there were ‘dead’ spots and a few speckles of white …where I didn’t want them. I finally, well into my painting realized that the paper was defective. I have had it maybe a year. I accidentally splashed just a few drops on a clean 140 hp paper. I quickly dabbed it with a towel and it did not lift leaving 3 spots! Thank you for your discussion. I have been searching for a sizing solution (pre-made). Daniel Smith has the paper ground but I was hoping to find liquid. Holbein has one but do you recommend any others?

Thanks for your useful blog. I also have this white speckles issue with my watercolor paper. Both Arches and Fabriano artistico from different brand new packages! I suppose it is an issue with the storage at the store… I will return some of it but still tried to figure out how to solve this. Soaking the paper helps, but simply applying a solution of 1/10 gum arabic and leaving it to dry restored the paper perfectly. Too much gum arabic would make layering difficult as paint would lift too easily, but 1/10 was great in my tests
