Painting the outside of your house is a big project that can completely transform the look and feel of your home. Whether you’re doing it yourself or hiring professionals, avoiding common mistakes can save you time, money, and frustration. This guide will help you understand the most common errors homeowners make during exterior painting — and how to avoid them.
Here are the top 7 mistakes to avoid when painting the outside of your house:
1. Skipping Surface Preparation
One of the most common mistakes is rushing into painting without preparing the surface properly. Dirt, mold, flaking paint, and dust can prevent the new paint from sticking well. Before you begin, make sure to:
Wash the exterior thoroughly (pressure washing is best)
Scrape off any peeling or cracked paint
Fill holes and cracks with exterior filler
Sand rough areas for a smooth finish
House painting tip: Good prep work can add years to your paint job’s life and improve the final look.
2. Using the Wrong Paint Type
Not all paints are suitable for outdoor use. Many people make the mistake of using interior paints or low-quality products for the exterior.
Use only high-quality exterior paints that can withstand harsh weather like rain, sun, and dust. Acrylic latex paints are a great option because they are durable and flexible.
Also, don’t forget to choose paint with UV protection to prevent fading.
3. Painting in the Wrong Weather Conditions
Painting the outside of your house during extreme weather is a big mistake. If it’s too hot, the paint dries too quickly and may not bond properly. If it’s too cold or humid, paint may take too long to dry, leading to streaks or bubbles.
Ideal painting temperature: Between 10°C and 30°C (50°F to 85°F) with dry weather conditions.
Always check the weather forecast before planning your painting job.
4. Choosing the Wrong Color
Picking a color without testing it on your home’s exterior is risky. Colors can look very different in natural light than on a small paint chip or a digital screen.
Before committing, paint a small section of your wall and check how it looks during different times of the day. This will help you avoid disappointment and ensure you love the final result.
5. Underestimating the Cost
One of the most overlooked aspects of painting the outside of a house in Ireland is the actual cost involved. Many homeowners assume that a quick paint job will be affordable, only to realise later that the expenses can add up — especially when hiring professional painters.
Costs can vary depending on several factors:
The size and height of your home
The condition of the exterior walls
Type and quality of paint chosen
Labour charges based on the complexity of the job
Need for scaffolding or special equipment
It’s also important to remember that exterior painting typically costs more than interior painting, due to the extra preparation, weatherproofing, and accessibility challenges.
To avoid surprises, always get a detailed quote from at least two or three local painters. Ask what’s included in the price — such as prep work, number of coats, and cleanup. Comparing this with the average cost to paint a room inside your home can also help you understand the pricing difference.
Proper planning and budgeting will ensure you’re not caught off guard and can complete your painting project stress-free.

6. Not Using Primer
Some people think they can save time or money by skipping the primer. But skipping this step can lead to uneven color, peeling paint, and a poor finish — especially on bare wood, new surfaces, or patched areas.
Always apply a coat of exterior primer before the main paint, especially if you’re changing from a dark to a light color.
7. Poor Planning and Execution
Exterior painting is more than just applying paint. It’s about planning every detail — from choosing the right tools and materials to knowing how many coats are needed.
Here are some quick house painting tips to avoid poor execution:
Always paint from top to bottom to avoid streaks
Use painter’s tape to protect trim and edges
Don’t rush — allow proper drying time between coats
Invest in quality brushes and rollers or use a sprayer for large areas
Final Thoughts
