It’s common to make mistakes and this can include using the wrong type of paint at home.
One of the main concerns people have is using damaged paint without noticing. This can include you shouting “I accidentally used moldy paint!” in a panic when you notice the difference in quality.
Using moldy paint is not an issue once it has been mixed in a separate bucket. When the paint dries, simply apply a second coat using a stronger paint to cover any noticeable splotches, stains, or discoloration.
This is not an issue to be concerned about and you can quickly resolve it without another coat. The most important factor is to ensure the moldy paint is not used again as a secondary coat.
Here is a look at what you should do when moldy paint is used accidentally including a step-by-step breakdown of the process.

Steps On How To Fix Moldy Paint On Surface
1. Inspect the Surface
The dangers of using old paint are well-known when it comes to damaged spots and uneven finishing. This is what most people get worried about.
In general, you will want to take the time to inspect the surface and better understand your options. If the surface is incredibly textured and damaged, this might be a sign that the paint didn’t settle at all.
In most cases, this is not going to happen. Even if you do use moldy paint at home, it will simply dry and looks respectable in the short term.
The first part of the process will be to inspect the surface and make sure it does get a chance to settle. You don’t need to touch or remove it at this stage. The only time paint should be removed is if the paint was completely ruined and didn’t settle at all.

2. Let The Paint Dry
You are now going to let the paint dry.
Yes, it might seem counter-productive to do this but it’s the only way to go. Letting the paint settle and dry is going to be essential to ensure the second coat is easier to apply.
If you attempt to remove wet paint, it might ruin the surface underneath and leave unnecessary marks. You want to avoid a scenario such as this because it will make your work harder. Look to paint on an even surface, which can include a primary coat of moldy paint.
While it is not ideal, it is not the worst scenario to deal with.
You can paint over moldy paint and that is what you should plan to do. Even if the dry paint still smells, you will have the opportunity to cover it with the second coat.
3. Clean The Surface Again
You will now want to clean the surface.
Take a cloth and begin running it over the primary coat. This will help even the surface and make sure any choppiness to the paint is eliminated beforehand.
A concern people have is the primary coat will begin to come off. If you let it dry, this is not going to be a problem at all because the coat will already have settled into place.
Take your time cleaning the moldy paint and ensure to do it from end to end. This is a must.

4. Apply a Second Coat Using Fresh Paint
The final step is to apply the second coat of fresh paint.
You will want to learn how to paint over moldy paint by using fresh paint. The goal is to take proper paint that has been verified as being fresh to complete the second coat.
If you do this, the moldy paint is going to become an afterthought even if it was going to pose a problem.
When you are painting over moldy paint, it is important to cover the entire surface. Don’t leave spots as that might become a problem later on as the paint starts to age. Go through every inch of the surface and make sure it is appropriately covered.
This is essential for doing things the right way.
Final Thoughts
I accidentally used moldy paint!
When you accidentally use moldy paint, it’s okay to let it dry and settle. The paint will likely have neutralized as soon as it was mixed in the bucket. If you are still concerned, it’s recommended to clean the surface and paint a second coat using fresh paint.
This will ensure the surface is protected and looks the way you want it to.
There is no reason to do anything dramatic with a scenario such as this one.
