Interior Painting Mistakes Almost Everyone Makes

When it comes to painting the interior of your home, achieving a professional finish is essential for creating a stunning and long-lasting result. 

However, many homeowners unknowingly make common painting mistakes when repainting or painting that can compromise the overall outcome. In this guide, we’ll explore the twelve most common interior painting mistakes and provide practical tips on how to avoid them. 

By learning from these pitfalls, you can ensure a flawless finish and transform your living spaces into works of art that will leave everyone in awe.

1. Insufficient Surface Preparation:

One of the most common mistakes is neglecting proper surface preparation. Knowing how often and when to paint is key, so proper prep work is critical. Failing to clean, patch, and sand the surfaces adequately can result in paint adhesion issues, uneven finishes, and visible imperfections. Take the time to thoroughly clean the walls, repair any damages, and sand them to create a smooth and even base for the paint.

2. Poor Colour Choice:

Choosing the wrong paint colour can have a significant impact on the overall aesthetic appeal of your home. Avoid rushing into colour decisions without considering factors such as lighting, room size, and existing decor. Test paint samples on the walls and observe how they look under different lighting conditions before making a final colour choice.

3. Skipping Primer:

Primer acts as a crucial foundation for the paint, ensuring better adhesion and enhancing the durability of the finish. Skipping the primer can lead to uneven coverage, poor colour vibrancy, and a shorter lifespan of the paint job. Invest in a high-quality primer and apply it before painting to achieve professional results.

4. Neglecting Proper Paint Application Techniques:

Improper paint application techniques can result in streaks, brush marks, and an uneven finish. Use smooth and even strokes, work in small sections, and maintain a wet edge to avoid visible lines. Consider using a high-quality brush or roller for better coverage and smoother application.

5. Overloading the Brush or Roller:

Overloading the brush or roller with too much paint can lead to drips, runs, and an uneven distribution of paint. Load an appropriate amount of paint onto your brush or roller, tapping off any excess before applying it to the walls. This will help you achieve a consistent and professional-looking finish.

6. Neglecting Proper Ventilation:

Good ventilation is often overlooked but is crucial for a successful paint job. Insufficient airflow can result in longer drying times, strong odours, and even paint not adhering properly. Open windows and doors or use fans to ensure proper ventilation during the painting process.

7. Rushing the Drying Time:

Patience is key when it comes to drying times. Rushing the process can lead to smudges, smears, and surface damage. Follow the manufacturer’s instructions for drying times between coats, and allow ample time for the paint to fully cure before moving furniture back into the room.

8. Ignoring Surface Imperfections:

It’s important to address any surface imperfections before painting. Ignoring cracks, holes, or uneven surfaces can lead to an unprofessional finish. Fill in gaps, repair cracks, and smooth out uneven areas with Spakfilla or putty before applying paint for a flawless result.

9. Inadequate Lighting:

Painting under poor lighting conditions can lead to uneven coverage and missed spots. Ensure proper lighting in the room by using a combination of natural light and artificial light sources. This will allow you to see the true colours and ensure a thorough and even paint application.

10. Lack of Protection for Floors and Furniture:

Failing to protect your floors and furniture can result in unwanted paint drips and stains. Cover the floors with drop cloths or plastic sheets and move furniture out of the room if possible. If removing furniture is not an option, cover it with plastic or use painter’s tape and plastic wrap to shield it from accidental paint splatters.

11. Switching Paint Manufacturers Mid Job

I was once guilty of this and learned from my interior painting mistakes, so I’m hoping to save you some future trouble. 

It’s so easy to underestimate how much paint for your project and must run for more, but the original store is miles further away. You can swing by this store that’s nearer to home and have them match the colour, right? Paint is paint. NO. All paint brands have their own signature propitiatory blends not even from product lines within the same brand. If you try to compensate with a colour match of different paint, it will be noticeable, even if it appears the exact same colour in the can.

Take the original paint can lid with the colour formula on it back to the same paint supplier. That way you can’t go wrong.

12. Selecting Paint Colours at the Paint Store

What could be the harm in this? You’re spoilt for choice. It can’t be that hard, can it?

Even though your local paint stores have tried to mimic natural lighting in their displays, you’re likely seeing the samples illuminated with over-saturated LED or fluorescent lighting. This doesn’t replicate how the colour will be viewed in your home under more natural lighting conditions. 

A pro tip is to take your colour samples outdoors to see them in ordinary lighting. This will help you visualise a colour’s true impact. Even better? Take the samples home with you and view them in the lighting in the designated room.

FAQ:

Q1: Should I sand the walls before painting?

A1: Yes, sanding the walls is an essential step in surface preparation. It helps smooth out imperfections, promotes paint adhesion, and ensures a professional finish. Use fine-grit sandpaper to gently sand the walls before painting.

Q2: Can I skip using primer if the walls are already painted?

A2: It’s generally recommended to use primer, even if the walls are already painted. Primer helps provide a uniform base, improves adhesion, and enhances the appearance and longevity of the paint job. It’s especially crucial when transitioning between dark and light colours or when covering stains and marks.

Q3: How can I avoid visible brush or roller marks?

A3: To avoid visible marks, use high-quality brushes or rollers and apply the paint with smooth and even strokes. Work in small sections and maintain a wet edge by slightly overlapping each stroke. This technique will help blend the paint and create a seamless finish.

Q4: Is it necessary to use painter’s tape?

A4: Painter’s tape can be a valuable tool for achieving clean and crisp lines. It helps protect adjacent surfaces and ensures precise edges. Use painter’s tape to mask off areas that should remain unpainted, such as trim, baseboards, and ceilings.

Q5: Can I paint over wallpaper?

A5: It’s generally not recommended to paint over wallpaper, as it can lead to a subpar finish. The wallpaper may peel or show through the paint, resulting in an uneven look. It’s best to remove the wallpaper before painting for a smooth and professional outcome.

Q6: How long should I wait before applying a second coat of paint?

A6: The drying time between coats of paint varies depending on the type of paint and environmental conditions. Refer to the manufacturer’s instructions for specific drying times. In general, waiting 2-4 hours is common, but it’s best to allow the paint to dry thoroughly before applying the second coat.

Q7: What should I do if I make a mistake while painting?

A7: If you make a mistake, act quickly. Use a damp cloth or sponge to remove the paint while it’s still wet. For dried paint, carefully sand the area and apply a touch-up coat. It’s always a good idea to keep some extra paint on hand for touch-ups and repairs.

Conclusion:

By being aware of and avoiding common interior painting mistakes, you can achieve a professional finish that transforms your home into a stunning masterpiece. Remember to thoroughly prepare the surfaces, choose colours wisely, use primer, and employ proper paint application techniques. Avoid overloading your brush or roller and strive for even coverage. By following these tips, you’ll be well on your way to a flawless and pro-level interior paint job.
