- 4. Hot Pressed —(smooth surface) Little difference between the front and back of the paper, and both are equally usable. Needs to be stretched to avoid buckling when wet; smooth, hard-size surface causes paint to puddle before being absorbed slowly by the paper. It takes all traditional watercolor techniques, but due to the absence of surface texture, the artist needs to work hard to prevent the painting from looking dull.
- 5. Hot Pressed —(smooth surface) Paint settles and puddles in fresh (and frustrating) ways often resulting in back runs and flowers; drybrush effect is more difficult to achieve and depends more on brushstroke; the absence of surface texture enables precise brushwork and an excellent capacity for detail. Difficult to make corrections: only minimal paint can be removed by rewetting and scrubbing. For wet-in-wet techniques, the base wash must be no more than damp or the colors run too far.
- 6. Cold Pressed—(subtle irregular texture) Generally considered easy paper to work on, taking most techniques very well. Perhaps the most popular choice of artists. Washes spread and dry flat and relatively bright. A new layer does not soften the dry color below, so that many layers can be applied before the colors begin to dull. Take care not to over-work the painting, however, as paintings overworked on this type of paper tend to look dull; drybrush is more subtle than with Rough. Both sides of the paper are usable. Excellent capacity for detail.
- 8. Lightweight (under 140lb) papers benefit from being stretched, otherwise they are likely to buckle when water is applied to them. Usually, paper over 140lb does not need to be stretched. If you intend to use a lot of water in your water colour painting, then it is important to stretch the paper before starting to avoid cockling – this is where the sheet wrinkles and forms ridges that are almost impossible to remove when substantial amounts of water are used.
- 9. Soak paper with clean water –either with a 2” wash brush, big sponge, or you can soak it in your tub or sink. (Be careful not to scratch the paper.) When paper is thoroughly soaked, lay it on the board. If any bubbles or buckles appear, simply lift on the side of the paper to the buckle. Now, slowly lay the paper back down on the board while applying gentle pressure with your wet brush to remove the buckle.
- 10. When it is completely flat, lay paper towels over the entire surface to remove the excess water. (Or you can roll a roll of paper towels over the surface.)
