How To Remove Old Paint From Walls?

If you want to learn how to remove old paint from walls, congratulations! You are in the right place. 

After so many trial and error and awry paint removal projects, I have figured out a way that effectively worked for me which I am going to share with you in this post. 

But before I proceed, let us quickly discuss the importance of removing old paint.
The Importance Of Removing Old Paint

Of course, you may be asking yourself, do I have to remove my old paint before I apply fresh coats of new ones? Is it important for me to go through the stress of removing the old paints? 

Well, removing old paints can be less stressful if you know how to go about it, and it is good for you to go through this process just as it is better for you to be safe than sorry. Do you want to know why I said that? 

The reasons go thus:

*** It helps to rid the surfaces of mildew and molds

Mildew and mold can build up over time, especially on the exterior parts of a building. 

By removing the old paint, you will remove the mold and mildew growing on your walls and also prevent it from spreading to other parts of the building.

*** It helps to create a clean and smooth surface

When it comes to painting, having a clean and smooth surface to paint is the key to achieving the best result. 

How will you feel if your new paint fails to adhere properly to the surface or start chipping and peeling after a few hours of application?

You would definitely feel frustrated and disappointed, hence, the need for removing old paint and preparing the surface for a new coat of paint.

By removing old paint, you will not only remove the flakes that can produce a rough and undesirable result but will also create a smooth surface that will aid the adherence of the new coat of paint.

*** Strip the surface of lead paint

Paint of houses built before 1978 tends to contain lead. Lead paints are unhealthy to have in homes or on other structures. It puts young children at a higher risk of developing serious health conditions if they take the paint or its residue into their mouth by accident. 

Removing this kind of paint, therefore, helps to maintain a healthy environment.

*** It helps to uncover hidden issues on the surfaces

When you remove old paint on walls or wooden surfaces, you will expose the hidden issues that have to be corrected before you apply a fresh coat of paint. 

The walls or the wood underneath may be cracked, invested by insect, molds or mildew, or suffering a bit of rot that you may not notice without removing the old paint. 

With the paint stripping process, you will identify these issues and correct them before they escalate into a bigger problem.

Hope you now agree with me that the removal of old paint is a task that should not be skipped or ignored? 

Now is the time to take you through the paint stripping process, but first, you need the right tool at your disposal in order to tackle this project efficiently. 

Tools and Materials

The tools and materials you need are:


* An oscillating tool with sanding and scraping attachments (in my opinion, a cordless oscillating tool is ideal for this project as it offers a good deal of convenience to work in tight areas).
* Dust sheet (may not be required for exterior paint removal).
* Brush 
* Vacuum cleaner
* Screwdriver
* Masking tape

* 40 to 150 grit sandpaper
* Tack cloth
* Liquid or chemical paint removers such as Ready strip or SmartStrip (you can also use a homemade paint remover liquid, I will teach you how to make one)

Safety tools

* Safety glasses
* Face or dust mask
* Rubber gloves 
* Earplugs

How To Remove Old Paint On Walls - Step By Step Guide

Step 1: Clear The Room Or The Area Near The Wall

Before you start removing the paint, you have to clear the area to make it easier for you to work faster and avoid paint splatters.

Remove the furniture, electronics, and other fixtures out of the room or to the center of the room if you have very limited space outside the room to keep your belongings. Cover the items that cannot be moved outside the room with dust sheets.

Remove the curtains, blinds, and fittings such as tracks, picture painting, tiebacks, etc. in the room and keep them out of the way. Unscrew the hardware that is fixed to your wall where possible.

Step 2: Apply Liquid Or Chemical Stripper To The Wall (Optional)

If your wall paint is not pealing or loosened on its own over time, you may have to use liquid or chemical paint removers to loosen the paint. 

These paint removers must be applied carefully as they contain strong chemical substances that can mar or discolor any surface if left for too long.

* Apply the stripper on your wall using a paintbrush.

* Allow the stripper to set on the surface for about five minutes or as directed by the manufacturer.

* Once the paint bubbles or get loosened, scrape it off from the surface.


* Chemical strippers can be very dangerous, and care must be taken when handling them.

* This step is optional and may not be required for wooden walls.

* You can make your own homemade liquid stripper if you do not want to use professional paint removers and this might take a little longer.

Homemade Chemical Stripper

To make your homemade chemical stripper, mix a part of acetone with three parts of mineral spirits and five parts of denatured alcohol. 

This solvents combination will help loosen the paint without causing serious damage. Spread it evenly on the wall with your painting brush and scrape away the paint.

Step 3: Scrape And Sand With A Multi-Tool

* Cover the floor and furniture with dust sheet and hold it in place with masking tape. You should also cover the switches and sockets with masking tape.

* Pick up your oscillating multi-tool and attach a steel scraper blade to the tool. Power on the tool and gently scrape off the blistered or loosened paint. Do not apply too much pressure to avoid gouging your siding.

* Once done, switch to a sanding pad with an 80 grit sandpaper attached to it and sand the area to remove the paint that is not removed by the scraper.
