1. Pick the best tools for cutting in
A good brush for cutting in paint is essential. A number of products are labelled as 'cutting-in brushes' and may have tapered bristles or a slanted end to help get that pleasing clean line.
However, any good-quality 2in brush, which won't shed bristles, is a sound choice. Don't go too narrow as you need to be able to paint far enough from the edge to roller in (without scuffing the adjoining wall).

1. Clear the area and protect furniture
Assuming you are painting at least one wall, make sure you move away anything that could suffer from paint splatters. If you're cutting in paint on a ceiling, you'll want to consider covering the whole floor in dust sheets.
Be sure to also cover any exposed light switches and plug sockets that could get in the way, and cover any larger pieces of furniture that can't be moved, in plastic sheets.
2. Start in the right place
It's advisable to paint a ceiling before the walls as it's a slightly trickier task and you are more likely to make errors that can be cleaned up later when you start painting the walls.
Wait until the ceiling paint has dried before you start painting the walls as to cut in you will need to apply tape to the ceiling and wet paint + masking tape doesn't mix. idea.
3. Tape off areas
Unless you’re confident that you have a very steady hand, it’s best to use frog tape to tape off the areas where the ceiling meets the wall to ensure you get clean lines. To do this start by places a strip of tape in the corner of the ceiling, right where the ceiling meets the wall.
Press down on it firmly until it lies flat against the ceiling. Then slowly drag the tape along the length of the ceiling in a straight line, flattening it as you go. If you are doing the entire room as apposed to one feature wall, repeat until the whole ceiling has a ring of tape around it.
Top tip: Make sure there are no air pockets, otherwise you run the risk of paint seeping through onto the ceiling.
4. Fill a small paint pail
Pour some paint into a small paint tray – you don’t need much at this stage, only about an inch, as this will prevent spills and saturating your brush too much by mistake.
5. Ensure your visibility is clear
Not clearly seeing what you're doing is a recipe for disaster with every DIY job but most especially when cutting in paint so consider a head lamp/torch to increase your visibility if the room you're working in is dark.
6. Make the first brushstroke
Dip your brush straight down into the paint, until the paint covers roughly a third of the bristles. Then gently tap, don't wipe, each side of the brush against the side of the paint container to avoid any drips.
Holding the brush with a pencil grip for control, make a brushstroke on the wall about two inches away from the edge you’re cutting in, to remove the excess paint. This should be about 12 inches long.
7. Move towards the line
Then turn the brush so that you’re using the narrow edge and paint your downward stroke up to 12 inches long, edging up to the Frog tape/ line.
Top tip: Make sure you don’t apply too much pressure as the paint ooze from the brush and create drips.
8. Paint the rest of the room
After you have finished cutting in, continue to paint the rest of the room with your best paint roller.
Make sure you reach as high as your initial 1–2" strip of wall paint and do not push or drag the roller all the way up to the ceiling.
9. Remove the tape
Once the paint is dry you can remove the tape and voilà, nice clean edges.
