A washi masking tape consists of a backing made from Japanese washi paper, or japanese rice paper, which is extremely thin, yet very strong and has a very low elongation meaning it won't stretch when using in an area where very long straight lines are required when spray painting. It is also highly tear resistant and therefore the perfect tool for creating precise masks for long and straight, razor sharp painting lines. On yachts, for example, very long and straight lines must be painted with absolute precision, or coachlines on canal boats - tesa® 4334 masking tape makes it easy to create highly accurate and straight edges.
