Accidentally Used Exterior Paint Indoors: What to Know and How to Fix It

Accidentally using exterior paint indoors can be a common mistake, especially for those who are not familiar with the differences between interior and exterior paint. It may be like a minor issue, using an incorrect type of paint can have consequences that affect both the appearance and the indoor air quality of your living space.

In this article, we will know about the difference between interior and exterior paint and provide a rectified solution to the situation if it happens to you.

The Difference Between Interior and Exterior Paint:

Interior and exterior paints are specifically formulated to meet the different requirements of their respective applications. Interior paint is designed to withstand regular cleaning, resist scuffs and stains, and provide a smooth and durable finish on indoor surfaces.

Exterior paint is formulated to fight against harsh weather conditions, such as UV rays, moisture, and temperature fluctuations while providing protection and longevity for outdoor surfaces.

Exceptions to the Rule:

While it is generally not recommended to use exterior paint indoors, there may be some exceptions to consider.

Using exterior paint with mold resistance properties might be appropriate. However, it is crucial to consult with a professional or knowledgeable paint supplier to ensure the suitability of exterior paint for indoor use in specific scenarios.

Is It Harmful?

Using exterior paint indoors can potentially lead to health and safety concerns. Exterior paints often contain higher levels of volatile organic compounds (VOCs) compared to interior paints.

High levels of VOCs can cause respiratory problems, eye irritation, headaches, and dizziness. It is important to address the situation promptly to minimize any potential health risks.

What to Do If You Accidentally Used Exterior Paint Indoors

If you accidentally use exterior paint indoors, here are some steps you can take to rectify the situation:

1. Ventilate the Area: Open windows and doors to allow fresh air to circulate and help dissipate the paint fumes. Use fans or ventilation systems to enhance air movement.
2. Decide on Your Plan: Assess the extent of the painting error. If the area affected is small, you may consider sanding and recoating with the appropriate interior paint. For larger areas or if you are unsure about the best course of action, consulting a professional painter or a paint supplier is advisable.
3. Repainting: If you decide to repaint, proper surface preparation is crucial. Remove any loose or peeling paint, clean the surface thoroughly, and ensure it is dry before applying the correct interior paint. Follow the manufacturer’s instructions for the best results.

Finishing:

Accidentally using exterior paint indoors is a common mistake that can have both aesthetic and health implications.

Understanding the differences between interior and exterior paint is essential to prevent such errors.

While there may be exceptions to using exterior paint indoors, it is important to consult professionals or paint suppliers to ensure the appropriate choice for specific situations.

If you find yourself in a situation where you have used exterior paint indoors, take immediate action to ventilate the area and decide on the best plan to rectify the issue.

By following the recommended steps, you can correct the mistake and restore the desired appearance and indoor air quality of your living space.
