Angle-cut Vs square-cut paint brush

"Hi Laura. Angled cut brushes are to help make the cutting (edges of the paint) easier and to create a neater finish without overlapping any paint. For example you would use this brush type at the top of the wall so that you don’t paint the ceiling or cornice the same colour. Square brushes are for the actual painting job to help you apply paint evenly over the surface.in summary, angled for borders, square for colouring in."

"Hi I am a painter and I get on with square brushes but that's my preference. An angle brush is for cutting in to get a nice straight line u can use on cutting into ceilings or can be used as cutting in to gloss work ie door frames skirting boards
Hope that helps"

"I prefer angle brushes give a better edge but for covering big areas like doors or walls use a flat edge brush"

"An angle brush is for what the title suggests.
Painting with a square cut brush is what one needs to paint all surfaces, apart from a roller of course.
An angle brush is for those angles and corners that require cutting in..Can be done with a square cut, but those who do not have painting experience or a steady hand, will probably end up with paint everywhere!
Where walls are coloured and ceilings white, go within 2 - 3 cm of newly painted ceiling with roller then finish and cut with a 1" or 3/4" angle brush..The perfect finish. Use also the point of the angle to drawer your lines.

"The advantage of an angle-cut brush is that it goes neatly into the corners ( ex. Where the ceiling and 2 walls meet)
The advantage of the square-cut it’s there when cutting it goes back ad forth while the angle-cut you either have to start again or turn the brush( when cutting-edge)
Otherwise, both brush can be used the same way.
It's just preferences really.
Hope this helps."

"I like to use a a angle cut brush for cutting in and I would say most painters I know do and use this brush for cutting in but really whatever you feel most comfortable with and works for you"

"I use a chisel tip brush for cutting in at more of a pace than a flat tip. It allows you to maintain keeping the brush at 45° angle and a good view of where your painting"

"Angle brush is better for cutting in with but you can use both"
