With the right paint, you achieve more than just aesthetically transforming any wall: this product with ancient origins increases its level of sun protection, prevents threats such as oxidation or humidity, and prevents plaster and other architectural materials from suffering accelerated deterioration.
But what paint is best for interior walls? As interesting as the influence of the brand on the final result is, the crux of this question forces us to delve into the different types of paint that are manufactured and sold in the current market: from acrylic, plastic, and metalized, to mineral and ecological thermal ones, among others.
Plastic Paints
Plastic paints have surprising qualities that justify their widespread use in partitions and interior walls. Its composition based on polymers and latex diluted in water stands out for its absence of odors and easy application on various surfaces. Unlike other paints, they lack volatile organic compounds, so they are non-toxic.
This type of paint for interior walls is available in two classes, with very different benefits: vinyl, intended for the protection of surfaces, moldings, and decorations, and acrylic, which provides the wall with additional resistance against humidity and solar radiation.
Silicate paint
Potassium silicate is the star component of this mineral paint, characterized by high breathability and impermeability, valid for surfaces where humidity is a problem and additional protection against molds and other microorganisms is required.
Silicate paint is a wise choice when a resistant finish is required, without the contaminating substances that are common in other products.
Answering the question of what paint to use for interior walls, silicate paints are one hundred percent recommended.
Acrylic paints
This paint for interior walls is manufactured with acrylic resins and pigments and stands out for its clean finish, free of odors, adhesive properties, and highly respectful of the environment.
According to renovation professionals, the qualities of acrylic paints suit rooms with poor ventilation. Since it does not yellow over time, it is kept in optimal conditions and can be washed with aqueous solutions, without fear of causing damage.
This type of paint is also compatible with facades and exterior surfaces. Over time, it degrades without emitting toxic substances, so it does not negatively affect human health.
Synthetic enamel paints
Decorative and protective, synthetic enamel paint is composed of synthetic resins and is used on interior walls, regardless of its constituent materials: wood, metal, plaster, etc.
Its most notable characteristic is durability because while other paints base their formula on water, synthetic enamel is based on a solvent. Easy to apply, this type of paint is available in a wide range of colors.
Ecological Thermal Paints
More innovative is the ecological thermal paint, capable of increasing the heat insulation in those interior walls that are in contact with the exterior on one side, thus combating annoying heat and cold leaks.
Its formula provided with ceramic microspheres makes the paint act as an air chamber that promotes the breaking of the thermal bridge.
Metallic Paints
When looking for something different from typical interior home wall paint colors, metallic solutions open up a world of possibilities.
It is a water-based paint, easily applicable on cement, plaster, and other common masonry materials, with an attractive, ready-made, and shiny finish.
Thanks to its hardness and resistance superior to other paints, metallic paint withstands friction and small impacts. It lacks bad odors, and the new products available on the market do not incorporate toxic compounds.
However, this paint tends to aggravate wall defects and imperfections, making it an option that will not satisfy all homeowners.
