Ordinary masking tapes must be removed as soon as possible after painting each coat as extended application will result in warping and glue residue staying on the wall. This is possibly why some say to remove the tape as soon as possible.
Fortunately, tape technology has come a long way and some tapes now have outstanding performance. A good example isBear 24mm x 50m Washi 14 Days Masking Tape. It is a professional quality, affordable masking tape featuring a high quality ultra-flat paper backing that resist bleed-through and ensures clean, sharp lines.
