Common Mistakes to Avoid

1. Inadequate Surface Preparation

Reason: Skipping steps like cleaning, patching holes, and priming the wall leads to paint issues and uneven finishes.
Solution: Thoroughly clean, repair any damage, and apply a quality primer before painting.

2. Using the Wrong Paint Type

Reason: Choosing a paint not suited for bathrooms (e.g., low-moisture resistance) results in peeling, mold, and mildew.
Solution: Select a paint specifically designed for bathrooms with high moisture resistance and mildew protection.

3. Ignoring the Overall Bathroom Design

Reason: The accent wall clashes with existing fixtures, colors, or style, creating a disharmonious look.
Solution: Consider the existing bathroom design and choose paint colors and textures that complement the overall aesthetic.

FAQs

What's the best type of paint to use for a bathroom accent wall?
For bathroom accent walls, you'll want a paint specifically designed for high-moisture areas. Look for paints labeled as 'bathroom paint,' 'mold-resistant paint,' or 'scrubbable paint.' These paints are more durable and resistant to mildew growth.
How do I prepare the wall before applying paint or tiles?
Proper preparation is key! Start by cleaning the wall thoroughly to remove any dirt, grime, or loose paint. Fill any holes or cracks with spackle and sand smooth. If you're painting, apply a primer to ensure better adhesion and even color coverage. If tiling, ensure the wall is clean, dry and level.
