The Silkpaint! company has specialized in this resist for years, and it shows. It has a lot of uses and advantages:
- Paint while resist is still wet!
- Add dyes to make colored resists.
- Use as a stop-flow when thinned with water.
- Steamable, or can be used with fixatives (painted on).
- Remove with cool water!
- No fumes, non-toxic!
For a water based resist, this one holds the lines pretty well. We used to get reports of it being more difficult to remove when steamed, but not lately as they have improved it even more. This one is nice because you can get it in quarts too.
Note: This resist is steamable, but even so, if the resist is subjected to the prolonged high heat of steam-setting it changes the composition of the resist and can make it really stick to the silk and hard to wash out. The best thing you can do at this point is GENTLY scrub with a SOFT toothbrush over the lines during the washing. It doesn't always work. If you use silk dyes and don't want to deal with resist being hard to wash out you can use solvent-based gutta and dry clean it out, or use colored water-based resists that you leave on the fabric. Water-based resist does wash out easily if you use a silk paint rather than a silk dye because the paints only require ironing to heat-set.
