Painting a house may seem simple, but there are several common mistakes that can affect the final result. At Bartolomé Bas Pinturas, we want to help you avoid these mistakes to ensure that your painting project is successful and long-lasting.

Inadequate surface preparation

Proper preparation is key to a good paint job. Many homeowners skip or rush this step, which can lead to problems such as peeling or staining. It is important to clean, repair and sand surfaces before applying paint to ensure optimum adhesion and a uniform finish.

Choosing the wrong paint

Selecting the right paint is essential. Many people choose paints based on colour alone, without considering the type of paint and its suitability for the surface or environment. For example, damp areas such as bathrooms and kitchens require mildew-resistant paints, while exteriors need paints that can withstand weather conditions.

Ignoring weather conditions

Painting under inappropriate weather conditions is a common mistake. Excessive humidity, intense heat or cold can affect how paint dries, resulting in a poor quality finish. It is vital to choose a day with suitable weather conditions and avoid painting in direct sunlight or when rain is forecast.

Incorrect paint application

Improper application technique can lead to an uneven finish, brush or roller marks, and insufficient coverage. It is crucial to use the right tools, such as quality brushes and rollers, and to apply paint with even, steady strokes. In addition, applying too many coats of paint or not allowing it to dry properly between coats can cause problems.

Neglecting safety

Safety is often overlooked in domestic painting projects. It is essential to use protective equipment such as gloves, safety goggles and face masks, especially when sanding surfaces or working with oil-based paints. Also, be sure to maintain good ventilation to avoid inhaling harmful fumes.

Lack of knowledge on drying and curing

Many people do not understand the difference between drying and curing paint. While drying refers to the evaporation of the solvent in the paint, leaving it dry to the touch, curing is the process by which the paint reaches its maximum hardness and adhesion. Using the painted surface before the paint is fully cured may result in damage or marking.

Failure to maintain paint tools

Proper care of brushes, rollers and other equipment is essential for a good paint job. Poorly maintained tools can leave lint, hair or residue on fresh paint, affecting the finish. Clean and properly store your tools after each use.

Neglecting the finishing touches

Finishing touches are crucial to a professional finish. This includes removing masking tape in a timely manner, touching up with precision and wiping up any splashes or drips. These small details make a big difference in the final appearance of your painting project.

Not testing colours in advance

A common mistake is not testing colours on the wall before deciding. Colour samples may look different under different lighting conditions and in combination with other colours in the room. It is always advisable to apply a paint sample to a small area and observe how it changes in natural and artificial light before committing to a colour for the whole room.

Underestimating the amount of paint needed

Many homeowners underestimate the amount of paint they will need for their project, which can result in colour differences between batches or the need to stop work to buy more paint. A good rule of thumb is to carefully measure the area to be painted and consult the manufacturer’s recommendations for coverage.
