Project progression (9)

Select a colour

  • Even before you pick up a paintbrush, the first thing you should ask yourself is, “How do I choose a paint colour?”
  • Get three or four colour samples mixed for you at your local paint or home centre.
  • To obtain a sense of the paint colours, test your colour samples on various areas of the space. Remember that the colour will fluctuate significantly depending on the room’s lighting.

Decide on a paint finish.

  • The most light-reflective paint finish available is glossy, and it is also the most easily cleanable. It works well for wood doors, cabinets, and trim.
  • A semi-gloss finish is practical in areas that need to be cleaned frequently, durable, and somewhat reflective. Excellent for utility rooms, closet doors, baths, and trim.
  • Because the satin surface has only a slight gloss, it is simple to clean. In addition, it works well in high-traffic areas like children’s bedrooms, kitchens, living rooms, and corridors.
  • Matte and flat coatings work well on walls that have flaws because they absorb light rather than reflecting it. Bedrooms, uneven walls, and walls with texture all benefit greatly from it.

Keep your furnishings and floors safe.

  • To guard against paint spills and splatters, tape down masking paper or rosin paper to the carpet and floor along the baseboards.
  • In the room you are painting, lay a drop cloth on the floor and cover any furniture there. Fabric drop cloths are more suitable for this because they are less slick than plastic ones.

Prepare and trim the walls.

  • It’s a good idea to wash all the walls and trim with a powerful cleaner like TSP before painting and repairing. The paint will adhere better if dirt and grease are removed.
  • To see the flaws on the surface of the wall more clearly, shine a utility light on it.
  • Any nails or bumps on the walls should be removed. Use patching compound or spackle to patch up the holes and cracks. Use sandpaper to smooth out each patch.
  • Before painting over the patched areas, always apply a coat of primer.
  • Remove the switchplates and outlets.

Decorate the ceiling.

  • You may avoid paint splatters on your walls and trim by painting the ceiling now.
  • A small container that you can grasp in one hand should contain around three cups of ceiling paint. Paint the edge of the ceiling around the entire space with a 2-1/2-inch angled paintbrush. Use an angled paintbrush to paint the ceiling’s edge around the entire space. (This is referred to as “cutting in.”
  • From one end of the room to the other, paint the ceiling with a 3/8-in. nap roller. One roller width at a time, and overlapping the prior row, apply the paint in the same way. Roll the paint in the opposite direction from the first coat’s direction if a second coat is required.

You should paint the trim.

  • Paint the trim before the walls in most cases. After allowing the paint to dry, tape off the trim and start painting the walls. Paint the walls first, let the paint dry, tape off the walls, and then paint the trim if the top edge of your trim is not wide enough to retain painter’s tape.
  • Before painting the trim, there are a few things to consider. Are you painting the windows and doors in addition to the trim, or just the trim? Removing a door before painting it makes the task much simpler.
  • Use a 2-1/2″ angled paintbrush and premium semigloss acrylic enamel paint. Don’t rush it, take your time, and do a beautiful job.

Apply Tape to the Edges

  • Before painting the walls, run painter’s tape—not masking tape—along the borders of the trim. A lovely clean line between the walls and ceiling will be created by taping along the perimeter of the ceiling to prevent brush and roller markings.

Put a Cut in the Walls

  • Cutting in one wall at a time and immediately rolling out the wall while the cut-in paint is still wet is an excellent practise. The cut-in paint will complement the wall paint much more effectively.
  • Pour around three cups of paint into a tiny container you can handle in one hand, as was specified in Step 4 of the procedure. With a 2-1/2-inch angled paintbrush, paint the ceiling’s perimeter as well as the edges of the trim and baseboards.
  • To prevent your brush from drying out in between cut-in coatings, wrap it in plastic wrap or place it in a freezer bag.

Roll paint on the walls.

  • Before you begin, make sure you swirl the paint with a paint stick.
  • Paint should be added until the roller tray is about halfway filled. If the tray contains too much paint, it can leak.
  • Roll paint on the wall from the baseboard to the ceiling after filling the roller with paint from the paint tray. To make sure the wall is covered, roll straight back down without reloading the roller.
  • Refill the roller with paint, then begin a new row by overlapping the one just finished. Paint the wall up to its maximum height. Lines of paint accumulation are frequently left behind by the roller’s edges. The lines should be rolled over once more to mix them in with the surrounding paint.

Clean up the mess after removing the tape.

  • Use a flexible putty knife to score the tape’s edge where it touches the wall before removing it from the trim and baseboards. (See image.)
  • Always use hot, soapy water to thoroughly clean your brushes and rollers.

An advice:

  • When painting, need good lighting; the ideal light is natural daylight.
  • Before painting, mix the paint for at least five minutes.
  • To prevent colour variations from gallon to gallon, pour all the paint into a five-gallon bucket.
  • Prior to commencing your endeavour, gather all the necessary tools.
  • Avoid putting paint on your freckles by painting your clothes and wearing a helmet.
  • Keep your paintbrush and rollers clean in a plastic bag that can be closed.
  • Keep a photo album of all the various paint labels on your computer or phone.
