The other main method for achieving a crisp line is “cutting in,” which uses an angled brush loaded with paint to carefully carve out a straight edge. This is the go-to for professional painters, because once you get it down, the process is much quicker than using tape.
Favored by professional painters, the cut-in method is pure freehand painting. No tape is used. Metal or plastic masking guards are not used, either. Using an angled sash brush and a special cut bucket (a small paint can without a lip), draw wide sweeps of paint close to but not touching the excluded area.
Many people opt to use masking tape instead of painters tape because it's cheaper. Sometimes the substitution works just fine.
Cutting in is the process of painting edges or straight lines with a quality angled brush without tape. It is all done freehand. This is the method that most professional painters use. The case can be made that using painter's tape is extremely time consuming and can be a colossal waste of time.
Green Frog Tape has medium tack (slightly less than typical painter's tape), and is safe on most surfaces. Taping off carpet and fully-cured walls are common places to use this version. Yellow Frog Tape is the best choice when needing to mask off anything with a delicate finish.
Most high quality painters tapes can stay in place for 14 days or more before being removed with no issues, although if the paintwork has been completed, and the paint is allowed to harden for too long, removing the tape will be more likely to crack the edge of the painted area and cause some damage, so ideally you ...
Because of its special design and residue-free results, painter's tape costs more than your average roll of sticky tape. That's because it offers premium properties and desirability for contractors and painters. Of course, the comparatively higher cost of painter's tape leads to vastly improved results.
The only edger tool you need to paint the edges of your walls and ceilings is an angled paintbrush. When you use this brush, you will find it much easier to get neat cutting in. That's because the angle of these brushes gives you more control and precision in tight corners.
Impact: masking tape can be used for painting, but it needs to be removed in a matter of hours; while painter's tape can be left on for a long time and still leave no residues when removed. Functional integrity: water-based paint can cause masking tape to collapse or crumble, letting paint drip on the surface below.
Do you paint walls or trim first? From a professional point of view, with interior painting, it makes the most sense to paint your trim first, then ceilings, and then your walls. It's much easier and faster to tape off trim than to tape off your walls. And you definitely don't want the hassle of taping them both.
Apply a very thin coat of paint
Paint over the edges of the tape with your base coat color using gentle strokes of a paintbrush: this will create a seal between the tape and the base coat. Sealing the edge of the tape prevents any seeping and ensures that your next paint color won't bleed underneath the tape.
Masking film
Masking films are an efficient alternative to tape, providing complete coverage of windows. Here's how to use masking films: Clean the window surface: As with the masking tape method, clean the window thoroughly. Measure and cut the film: Measure the window dimensions and cut the masking film accordingly.
As crazy as it may seem, no one ever tells you what to do after you're done painting: how long to leave painter's tape on after painting? If you peel it too soon, you risk the paint dripping where it shouldn't; if you leave it on too long, you risk chipping away some of the paint when you take it off.
If you need to write on tape for any reason, get a Sharpie ultra fine tip pen. It dries quickly, does not bleed through, and shows up well.
Always cut in first then continue painting with a roller. Cut in and paint with a roller one wall at a time. If you cut in all areas first and then roll the entire room, the paint that was applied when cutting in will have dried quicker and you will be left with a patchy, uneven finish.
Buy a Good-Quality, Angled Sash Brush
Angled sash brushes are easier to control and provide a better cut-in for a new painter. The angle gives you a fine line of paint to make a straight line from.
Wait until the paint is dry to the touch before removing the tape. Check the paint can for the manufacturer's dry times. Use a putty knife or razor blade to score along the edge of the tape. This prevents paint from being pulled up with the tape and from cracking along the paint line.
Don't: Apply tape the day before—or earlier—you paint. The glue on painter's tape is intentionally less sticky than regular masking tape, so it will start to release a little on its own from tiny imperfections in the surface, which could allow paint to bleed under it.
The difference between painter's tape and masking tape lies primarily in the adhesive. Masking tape is designed to be extra sticky and not come off, while painter's tape is designed to have a low tack that makes it easier to remove after painting and less likely to leave residue.
Green painter's tape, often marketed as "multi-surface" or "delicate surface" tape, offers similar benefits to blue tape but with added features for extra protection. It's designed for use on more delicate surfaces where the risk of damage or adhesive residue is higher.
The other main method for achieving a crisp line is “cutting in,” which uses an angled brush loaded with paint to carefully carve out a straight edge. This is the go-to for professional painters, because once you get it down, the process is much quicker than using tape.
If you have recently painted your walls, this usually indicates that the paint has not fully cured. Stretching the tape as you apply it can also cause it to lift off of the wall. It could also mean that the surface was not properly prepared.
'For the quickest and most economical alternative to masking tape when painting edges, use a sheet of paper or thin card,' confirms Pat. 'It works along the same principle as a paint shield by forming a barrier between the paint and the surfaces you want to protect.
