How to paint your house interior

Painting your interior can be a great way to update your home’s appearance. No matter what it is, you can achieve professional-looking results with the proper preparation, tools, and techniques. Taking the time to properly prepare the walls, choosing the right paint and painting supplies, and doing the job with the proper methods are all essential steps in getting the desired look. Doing these things right can help ensure your paint job lasts for years.

​Here’s a step-by-step guide on the interior painting of a house.


Choose your tools:

  • ​Paint
  • Paint roller
  • Paint roller extension pole
  • Drop cloths
  • Paintbrushes
  • Paint tray
  • Sandpaper
  • Painter’s tape
  • Rags
  • Putty knife

Determine the color:

​Consider the function of the room before choosing the color. You also must consider the amount of natural light in the room because it can affect your selected color. It is a good idea to test a small area of the wall with the color and then look at it at different times of the day to make sure you like it. Look at the latest color trend to get some inspiring ideas. And do not be afraid of experimenting with colors to the extent of creating your shade of a color. A paint specialist at any paint store like Home Depot can certainly help you with it.
it is not a bad idea to look at the color psychology to make choices.

Estimate the Quantity of paint:

​One gallon of paint covers 400 square feet, and one quart covers 100 square feet. To determine the square footage of the walls, measure the perimeter of the walls, multiply the perimeter by the ceiling height, and subtract the area of the doors and windows.
For example, if your room is 15 X 20 feet with 9 feet ceiling and has 2 doors and one window of the standard size then your calculation might look like this.
  • Perimeter of the room:
    • (15 + 20) X 2 = 70 ft.
  • Multiplied by the ceiling height
    • 70 X 9 = 630 sq ft.
  • Subtract the two standard doors and one window:
    • 630 – ( 21 X 2 ) – (15 X 1) = 573 sq. ft.
So you may need around
573 / 400 = 1.43 gallons of the paint for one coat.
If you want two coats then you may need to double the quantity and keep a little extra. so you need to buy 3 gallons and 1 quart.

Prepare the Room:

  • Taking all the furniture and fixtures off the ground, including HVAC registers, electrical switches, and outlet covers, is the first thing you should do. 
  • Ensure surfaces are free of cracks, holes, dents, or other imperfections. 
  • Fill and repair holes or imperfections using a putty knife with caulk or a lightweight spackling compound. 
  • Putty knife the excess spackling and let it dry. 
  • To smooth the repaired areas flush with the surface, use a piece of sandpaper or a sanding sponge. 
  • To clean the surfaces, dampen a towel or sponge and allow them to dry.
  • Wearing a respirator mask when working on an interior house painting project is always advisable.

The paint tape should be placed as follows:

  • ​You should always press the painter’s tape flat and evenly to prevent bleed-through. 
  • When painting non-textured surfaces, mask off the edges where the tape meets the wall’s edge and apply the tape in short, overlapping strips, pressing down firmly along the edges. 
  • Simply slide a screwdriver along the edge of a textured ceiling to create a small, unnoticeable, texture-free surface. This will make painting straight edges much more effortless. 
  • Mask off the inside edge of an accent wall from the rest of the room if you intend to have one.

The paint tape should be placed as follows:

You must protect whatever you are not painting, like your carpet, hard floor, or heavy furniture you cannot move. You may use drop cloths for this purpose. There are different types of drop cloths.
  • Paper: it is a very inexpensive option and suitable for furniture, but it is not great for floors because they tear easily
  • Plastic: They are inexpensive and do the job well. The only issue with them is that it needs to absorb the paint.
  • A paper/poly drop cloth is the best of both paper and plastic–they’re inexpensive, disposable, and absorb paint drips while providing more protection for what’s underneath. They also offer some slipping protection. 
  • Although expensive, canvas drop cloths are the most durable and absorbent.

Prime the walls:

Adding primer to walls before painting requires time, but it gives the surface a texture you can use to paint. It allows the paint to adhere to the primer and produce a high-quality finish on your wall. By pre-tinting the primer rather than leaving it white, you can reduce the number of colored paint coats required.
  • When priming the interior walls, starting with the proper techniques is essential. Use a paintbrush to “cut in” around the room’s edges, corners, and frames.
  • Be careful not to let the border areas dry before overlapping them to avoid a difference in sheen between the two coats.
  • Attach the roller cover to the paint roller.
  • In a tray, pour the primer paint.
  • Make sure the roller is fully covered with paint by dipping it into it.
  • Remove excess paint by passing the roller over the ridged area of the paint tray a few times.
  • Using V- or W-shaped strokes, begin painting in 3-by-3-foot sections, working your way down the wall until the section is covered.
  • Roll in one section at a time, moving from top to bottom and from one side of the wall to the other
  • Overlap areas of wet primer
  • Reload your roller as needed.
  • Once the primer has dried, fold a quarter-inch-thick strip of sandpaper into quarters to remove bumps and ridges.
By following these techniques, you can achieve a smooth and professional-looking finish.

Mix your paint:

​To ensure the paint is stirred consistently, use a wooden stick and re-stir often during the project. If you mix it consistently, it’ll prevent the ingredients from separating and compromising the actual color. If you use more than one gallon of paint, combine the cans in a large bucket just in case the color changes slightly.

Apply paint:

  • Paint walls one at a time to achieve a smoother and more seamless look by blending wet paint with wet paint
  • Use V- or W-shaped strokes when rolling the paint on the wall.
  • Smooth the coat by continuously rolling over the painted area from top to bottom.
  • Overlap areas that you already have painted to blend different areas seamlessly
  • Frequently remix your paint using a mixing stick or tool, especially after leaving the paint sitting for an extended period.
  • Wait 2 to 4 hours for the first coat to dry before applying a second coat and follow the same process and techniques for priming the walls.
  • Blend the sections as you go to maintain uniformity in the color.
  • If doing a large job, mix several gallons of paint into one 5-gallon bucket to ensure color consistency.

Clean the Work Area:

​If you use acrylic-latex interior paint, clean the brush with warm water and a paint comb. Remove drop cloths and let them air dry outside. Wad up plastic sheeting and throw it away. Wait until the next day to remove the painter’s tape. Pull the paint tape straight back to create a sharp line by removing the paint.
