How to Paint Interior Walls like a Pro: Tips, Tools, and Advice

Interior walls can be a challenge to paint due to the attention to detail needed when painting walls and trim in your home. Just to put it in perspective, you should expect to pay a professional painter at least $10,000 to paint a traditional 4-bedroom home. But the good news is that with some basic painting techniques you will be able to save a lot of money while making your home improvement project look great in no time.

Not only do interior walls consist of weird angles that can slow down the painting process, but you also need to pay special attention to the interior paint because your family and guests are close to the walls at all times and they can spot imperfections if you’re not careful. This means you need to prepare your walls and apply even coatings of paint to ensure the final project looks great.

You will want to do everything you can to prevent drips or streaks with drop cloths and other painting supplies so you won’t have to clean up as much after you complete the painting job.

In this blog post, we’ll provide tips on how to paint interior walls like a pro. We’ll also give you advice on the tools and supplies that you need, as well as the process that you should follow. Follow our tips and you’ll be able to achieve beautiful interior walls for your home!

The Best Ways To Paint Interior Walls

Interior painting is not a one-size-fits-all project, so you need to take into account the surface you’re working with and do your research before getting started on your interior painting project.

Let’s take a look at the steps you need to take to ensure your interior painting project looks amazing and that you can avoid common mistakes people make with painting the inside of their homes.

1. Choose The Right Painting Supplies For The Job

One of the most important things that you need to do when painting your interior walls is to choose the right tools for the job. Here are just a few of the tools you will need to ensure your painting project is done in a professional and efficient manner:

  • Paint Roller & Covers: 3/8″ sleeves are best for most finishes, but you may need a 1/2″ sleeve for textured walls.
  • 5-Gallon Buckets: You will need one bucket for each color that you want to use, and you will use this bucket to reload your paintbrush and roller during the project. You can also use a paint tray to reload the paintbrushes and rollers, but a bucket can hold a gallon of paint without the risk of accidentally knocking the paint over onto the floor.
  • A Roller Grate: This will help distribute paint on your rollers and remove excess paint before applying it to your walls. You can use the roller grate to evenly distribute paint on the roller covers to improve paint adhesion.
  • Painters Tape: Use this to tape off areas between the trim and walls around your home. This will ensure you have clean lines and a professional look at the end of your painting project.
  • Paintbrushes: An essential tool for any painting job for cutting and painting the trim and baseboards around your home. Be sure to have at least one brush for each color that you intend to use so you don’t have to waste time cleaning your brushes between each use throughout the day.
  • Canvas Drop Cloths: The help to prevent splatters of paint from getting into your carpet or on your floor.
  • You will need caulk, putty, and a putty knife to smooth out any dings or scratches on the walls. This will ensure the painted surfaces will look great after you complete the painting.

No matter what type of paint you intend to use on the walls, always make sure that your brushes and rollers are properly cleaned before and after each use. This will help to ensure that the bristles stay in good condition and that they don’t become frayed or damaged during the painting project.

2. Prepare Your Walls Before You Begin Painting

Once you have all of the necessary painting supplies ready for your painting project, it’s time to start preparing your walls. This is an important step in the process because it will help to ensure that your paint goes on evenly and looks great once the painting project is complete.

The first thing you need to do is clean your walls to remove dust, dirt, and grime before painting. If you notice areas of the walls that require additional cleaning, you can use a sponge or rag and some soapy water to tackle dirty areas of the wall.

Next, you need to repair any cracks or holes in your walls to ensure you have a professional look. You can use putty or spackle to fill in any small cracks and holes and then use sandpaper to smooth those areas down before you apply the first coat of paint to the walls.

You should also remove all light switch covers and outlet covers before painting. This is much easier than trying to paint around these covers, and removing the covers makes the entire process much faster and easier.

Before beginning any interior painting project, be sure to do your research and choose the right tools and materials for the job.

By taking the time to prepare your walls properly, you can avoid common mistakes and achieve professional-looking results.

3. Cut In The Room Before

After your walls are clean and repaired, it’s time to start painting! But before you reach for the paint roller, you need to “cut in” the room first. This simply means painting a three- to four-inch strip around the ceiling, trim, and baseboards of the wall with a paintbrush.

Cutting in is important because it helps to create a clean line between the wall and ceiling or trim and applies paint to areas where the paint roller can’t reach.

To cut in, load your angled paintbrush with paint and then tap off excess paint using the grate that you have in your 5-gallon bucket.

Once you have the paint loaded on the brush, you will need to hold the paintbrush at a 45-degree angle and use small, even strokes to apply the wall paint directly against the trim around the area.

Since you will likely be cutting around door frames, window frames, and baseboards, it’s best to lay down a layer of painter’s tape before cutting the room.

You will still need to be careful to avoid mistakes, but the painter’s tape can help you produce clean lines and speed up the process since cutting the room typically takes the most time of any interior painting project.

4. Use The Roller To Spread New Paint On Your Walls

After you’ve cut in the room, it’s time to break out the paint roller to fill in the majority of the surface area around your interior space.

To start, load your roller with paint in the 5-gallon bucket and roll it on the grate in the bucket before you apply paint to the wall. This will even out the paint on the roller cover and ensure you don’t put too much paint on the wall since this can cause imperfections during the paint drying process.

Once you have the paint on the roller cover you are ready to apply paint to your walls by rolling the paint roller up and down the wall in even strokes. Be sure to overlap each stroke slightly to ensure that you’re getting full coverage.

As you’re painting, keep an eye out for any drips or runs in the paint, and if you see drips it means that you have too much paint on the roller so you will need to remove excess paint in the bucket before your next application.

If you’re painting a large room or working on multiple walls, it’s best to divide the room into sections and work on one section at a time. This will help to avoid missed spots and uneven coverage. Continue applying paint in this fashion until the room is completely covered in an even, professional-looking finish.

5. Avoid Streaks When Painting

One of the most common mistakes people make when painting interior walls is that they don’t use smooth strokes with the roller or paintbrush. This can cause streaks in the paint as it dries, which will ruin the professional look you’re going for.

To avoid streaks, be sure to use even strokes with your roller and brush and always overlap each stroke slightly. You should also avoid painting in direct sunlight since this can cause the paint to dry too quickly and create imperfections. You can also turn on a fan to circulate air in the room to ensure the paint dries evenly throughout your project.

6. Let Your Paint Dry, Then Apply A Second Coat As Needed

Once you’ve finished painting the room, it’s important to let the paint dry completely before applying the second coat of paint when needed.

This typically takes around 30-60 minutes before the paint is dry enough to apply a second coat, but can vary depending on the type of paint and the conditions of the room so be sure to read the label of the paint that you are using.

After the paint has dried, take a close look at your walls and decide if a second coat is necessary. If you see streaks and the original paint color on the wall doesn’t show through the new coat of paint then you may not need to apply a new coat of paint to the wall or trim sections of the room.

In most cases, one coat is sufficient, but if you’re painting over a dark color or notice any areas that need more coverage, go ahead and apply a second coat of paint. You may also need to apply a second coat around the areas that you cut into the wall with your brush since brushes hold less paint than rollers.
