Step 1: Prepare the Area

  • Place a plastic sheet on the floor right under the corner that’s in for a paint job.
  • It stops paint from dripping onto the floor and creating stubborn spots.
  • Make sure the sheet covers the surrounding area and the furniture.
  • That way, the paint won’t wander where it shouldn’t.
  • Grab some painter’s tape and use it to protect edges that should stay paint-free.
  • If the corner meets a wall or trim, tape that connection too.
  • For an even smoother experience, get a putty knife and gently press it against the tape.
  • This helps the tape stick well and keeps paint from sneaking underneath.

Required Tools

  • Plastic sheet
  • Painter’s tape
  • Putty knife

Step 2: Painting Prep Work

  • Take your step tool and place it beside the corner.
  • Take a clean piece of cloth and dip it in water.
  • Squeeze the water out of the cloth so it’s damp and not fully wet.
  • Using the damp cloth, wipe from top to bottom.
  • This gets rid of any dust or dirt that may be there.
  • A clean surface will also help the paint stick better.
  • Get the painter’s tape and cut a few pieces, each 1 foot long.
  • Put it over the baseboard that is at the bottom edge of the corner.
  • Run your fingers over it to make sure there are no trapped air bubbles and the tape is snug.

Required Tools

  • Step tool
  • Clean cloth
  • Water bucket
  • Painter’s tape

Step 3: Begin Painting

  • Make sure to drip the extra paint off the brush.
  • Now, gently put the brush right along the corner and keep it pressed lightly.
  • Start moving the brush upwards and downwards alongside the corner.
  • Make sure you are spreading the paint evenly.
  • Keep the bristles smoothly and lightly touched against the surface.
  • Before you switch places, make sure you have at least five layers of paint.
  • This ensures even coverage of paint all over the corner.
  •  Once in a while, redip your brush in the paint.
  • Keep on painting up and down the height of the corner to smoothen out uneven surfaces.

Required Tools

  • 2½-inch paintbrush
  • Paint

Step 4: Keep Brushing in Short Strokes

  • Continue making these short strokes until you’re sure that you have covered the whole corner.
  • Most of the strokes will be parallel to the corner’s edge during the process.
  • However, you may also need to make perpendicular strokes to even out some areas.
  • Make sure these crossing paint layers blend seamlessly.
  • This method ensures there are no bristle marks left on the new paint.

Required Tools

  • 2½-inch paintbrush
  • Paint

Step 5: Switch to a Roller

  • Take your paint roller and make sure it is clean and free of any old paint.
  • Now, take the paint and pour it on a paint tray.
  • Place the roller on the tray and start rolling.
  • Make sure the paint is evenly spread all around the roller.
  • Shake the extra paint off.
  • Position the roller over the edge of the corner gently and start rolling up and down.
  • Follow the same 5-layer rule as the brush for completing one area before you move upward or downward.
  • While painting, make sure the paint doesn’t get off the corner and is blending nicely.
  • This method ensures that the new paint mixes really well with the brush paint.
  • Once you have covered the whole corner, give the paint some time to dry.

Required Tools

  • Paint roller
  • Paint tray
  • Paint

Step 6: Remove Painter’s Tape

  • Wait until the paint in the corner is completely dry before removing the tape.
  • This stops the paint from peeling up when you pull the tape.
  • Use a putty knife with a thin edge to gently press on the tape.
  • Press where the tape touches the painted part.
  • This helps the tape come off without pulling the paint with it.
  • Hold the end of the tape and start peeling it off.
  • Pull it off at a 45-degree angle.
  • This way, the tape won’t tear or leave bits of paint behind.
  • Take your time and peel the tape off slowly.
  • This ensures the corner looks clean and neat after removing the tape.

Required Tools

  • Putty knife
