What’s the difference between water based and solvent based gutta/resist?
The main difference is in the dry times. A solvent gutta will dry within a minute after application, allowing you to paint your silk colours immediately. A water based gutta /resist takes about 10 minutes to dry. The main advantage of water based gutta/resist is the easy removal or wash out. It comes out in the finishing rinse with warm water. Solvent gutta requires dry cleaning to properly remove. Most painters leave solvent gutta in though. Solvent guttas are known for providing a very strong resist line with little issues of dye break ing through. Water based gutta is a bit weaker line and more care must be taken when painting over them as it may dissolve the line.
