How to Touch up Wall Paint Like a Pro in 7 Foolproof Steps

Whether it’s a scratch, a scuff, or a spot that wasn’t fully covered the first time, touching up paint can seem like a daunting task. But don’t worry, it’s easier than you think.

In this post, I’ll walk you through the steps to touch up wall paint like a pro. I’ll also cover the tools you’ll need, how to prepare the area, and the best techniques for blending the new paint with the old.

So, let’s get started and give your walls the flawless finish they deserve.

Step 1. Gather Your Materials

The success of any paint job depends on having the right tools and supplies. For a touchup project, you’ll need the following:

  • Paint – You can use leftover paint from the original job or purchase a new can of paint that matches your walls.
  • Putty knife – A putty knife is used to remove old paint and debris from the wall.
  • Sandpaper – You can use fine-grit sandpaper to smooth out the surface of the wall before painting.
  • Paintbrush – Choose a natural or synthetic brush that will give you an even, consistent finish.
  • Roller – A roller is great for applying paint to large surfaces quickly and evenly.
  • Drop cloths and painter’s tape – Use drop cloths to protect your floors and furniture from spills and painter’s tape to keep paint where it belongs.

Step 2. Prepare the Area

Preparing a wall before a touchup is important as it ensures that the paint adheres to the wall properly and looks its best. Leaving dirt and debris on the wall can lead to an uneven paint job and possible cracking. 

Scrape away flaking paint 

If there are any areas of flaking paint, use the scraper or putty knife to carefully remove them from the wall. Be sure not to gouge or damage the underlying surface, as this can compromise the integrity of the wall.

Once all of the flaking paint has been removed, use a vacuum cleaner and dustpan to remove any remaining particles from the area.  

Clean the area

Once all of the flaking paint is removed, use a damp cloth to wipe down the area. This will remove any dirt or dust that may have accumulated on the wall and also help to ensure that the new paint adheres nicely. 

Repair any damage

If there are any holes or dents in the wall, use a putty knife and some spackling compound to fill them. Once it’s dry, lightly sand the area to ensure an even surface for painting. 

Sand down any rough spots

Use medium-grit sandpaper to lightly sand away any dents or rough spots that may be on the wall. This will help to create a smooth surface and ensure an even paint job.

After sanding, use a damp cloth to wipe down the area one last time and make sure it’s free of all dirt and dust particles before painting.

Step 3. Apply Primer

Once the wall is prepped and ready to go, it’s time to apply primer. Primer helps seal the wall and create a better bond between the paint and the wall surface. Be sure to use an even coat of primer and let it dry completely before moving on to painting. 

Step 4. Match the Paint Color and Finish

The first step in any touchup job is finding an exact color match for your existing paint. To do this, bring a sample of your wall color to the store and compare it to paint chips.

If you can’t find an exact match, try mixing two different colors together until you get the desired effect.

Once you have matched the color of your existing paint, it’s time to match the finish. The most important factor when matching a finish is understanding what type of sheen or gloss level the wall currently has.

For example, if your wall is painted with a semi-gloss finish, make sure to choose a paint that also has a semi-gloss finish.

A different sheen or gloss can throw off the look of your walls and cause a noticeable difference between the touchup paint and the original paint job.

Step 5. Apply the Paint

Once you have chosen the paint and supplies that you need, it’s time to get started. Here are the 5 steps for a seamless finish.

1. Prepare the paint

Make sure the paint is stirred and mixed thoroughly before using it. Paint can separate over time, so it’s important to mix the paint completely beforehand. Use a stick or stirrer to mix the paint and ensure that it’s consistent.

2. Thin the paint

Thinning the paint can help it to spread easier and make sure that you get an even coat. As a general rule, latex paint can be watered down by 5-10% before it is applied; however, check for the manufacturer’s recommendations on the paint can.

3. Pick your tool

Use a small brush for small touchups and a roller for larger areas. For areas measuring less than an inch, a foam brush is recommended. Once you’ve chosen the tool, make sure to load it up with just enough paint so that you can cover the area in one stroke.

4. Paint the wall

Start in the middle and work your way out in a sweeping motion. Paint with even strokes in one direction, going over each area until you have covered the entire section. Thin and even strokes will help you to achieve an even coat of paint on the wall.

4.1. How to apply the paint with a brush

Start by cutting in the edges of the area to be painted. Dip your brush into the paint and then tap off most of it on a piece of cardboard or newspaper; too much paint will cause it to drip down the wall.

Using light, even strokes, stroke the paint onto the wall, being careful not to apply too much paint in one area. Work from top to bottom and left to right, allowing the paint to dry between coats.

To further ensure an even finish, feather out the edges of each stroke with the tip of your brush (see step 5).

Once you have finished painting, allow the touchup to dry completely before applying a second coat if needed.

4.2. How to apply touch-up paint with a roller

Load the roller with paint, but don’t soak it too much. Start by using the corner of the roller to cut in the edges and then roll outwards towards the center of the wall. Use light, even pressure when rolling, and overlap each stroke by about one-third.

Make sure you cover the entire area with paint before applying a second coat if needed. Once your touch-up is dry, it should blend seamlessly with the rest of your wall.

5. Feather the edges

Use a brush to “feather” out the edge of each stroke. This will help to ensure that there are no noticeable lines between the original paint and the touchup job.

To achieve a seamless touch-up, start at the inside of the repaired area and use a feathering technique with the brush to blend the edges into the surrounding paint.

Feathering involves extending brush strokes slightly beyond the touched-up area to create a smooth transition between the new paint and the existing paint.

Step 6. Drying and Blending

Generally speaking, latex paint will be dry to the touch in about an hour and ready for a second coat in four hours.

Oil-based paints have a much longer dry time. It generally takes up to eight hours to be dry to the touch and a full 24 hours before a second coat can be applied.

Curing is just as important, though. Curing is the time needed for the paint to harden and achieve its full durability.

Latex paint usually takes a week to fully cure, while oil-based paints can take up to a month or longer. During curing, it is recommended not to do anything to the newly touched-up walls, such as cleaning or mounting pictures.

Once the paint has cured, you should be able to blend it seamlessly with the rest of your wall. If you feel that there is still a noticeable difference in color or texture between the touch-up and the wall, you may need to give it an extra coat of paint for a better match.

Step 7. Clean-up

Why is cleanup important? 

Paint that has been left on brushes, rollers, and other tools can dry up and become difficult to remove.

Plus, it can also lead to a build-up of dried paint residue, which takes even more time and effort to remove. That’s why it’s important to clean your tools properly after each use.

What you need to do the job 

Before you begin cleaning up, make sure you have all the necessary items on hand. This includes a drop cloth, lint-free rags or paper towels, a bucket of warm water and mild detergent, an old toothbrush or paintbrush, and a putty knife.

Depending on how much paint was used during the touch-up job, you may also need some sandpaper or steel wool.

Clean up your tools first 

The first step in cleaning up after touching up wall paint is to clean your tools. If you use a brush or roller, clean them off with warm soapy water.

This part of the process is very important. If you don’t clean your tools properly, they could become stiff and unusable for your next project. 

If you have latex paint on your brushes, wash them with soap and warm water until the water runs clear.

For oil-based paints, use mineral spirits instead of water. Once these supplies have been washed, rinse them with cold running water. Let your tools dry completely before stowing them away.  

Carefully remove excess paint 

Once your tools are cleaned and put away safely, it’s time to start removing any excess paint that may have dripped during the touchup process.

Start by blotting up as much of the paint as you can with a paper towel or lint-free rag. For any hard-to-remove areas, try using a putty knife or an old toothbrush and some warm soapy water.

Finally, for any remaining paint splotches, you may need to use some fine sandpaper or steel wool. Carefully rub the area in a circular motion until all traces of the paint are gone, and you are left with a smooth surface. 

Vacuum and mop floors 

The last step is to make sure all of your floors are free from dust and debris from sanding prior to painting as well as dirt from walking around while working on the project

Vacuum thoroughly using an attachment hose for those hard-to-reach places like under furniture pieces where dust may have accumulated over time without being noticed until now.

Once vacuuming has been completed, mop all floors using either a damp mop or a wet Swiffer pad, depending on what type of flooring material you are dealing with.
