Choosing quality interior paints is the best decision you can make when painting the walls of your home, whether you are doing it yourself or commissioning the job. If you do not want to regret it, that your budget multiplies or that the colour of the plastic paint fades, you have to read this.
We are going to explain what characteristics the paintings must have to be considered quality paintings, and what you should base your choice on. But above all what is the difference between a “good paint” and a cheap one.
Characteristics of quality interior paints
Good quality interior paints have several characteristics that we are going to list here:
- They apply more easily. Their texture makes them ideal to be spread easily.
- Leaky less. The quality paints for interiors splash during application.
- Achieve greater coverage. Good quality paints cover original colour and imperfections very well, often in one application. Thus, you save product and money.
- Colours remain unchanged. The colours of good quality paints remain unchanged longer, thanks to the quality of the pigments.
- They resist dirt better. Quality interior paints have greater resistance to stains, preventing them from penetrating. Cleaning the painted walls is more superficial and simple.
- They absorb touch-ups better. If you need to touch-up a good quality paint, you can do it more easily and without being noticed.
- They are not attacked by mould. Quality paints have better behaviour against mould produced by humidity.
The components of quality interior paint: what is their proportion.
Paint has three main components: pigments, binders, solvents and additives.
- Pigments are those that provide the colour, and can be of two types: quality paints have pigments such as titanium dioxide in their composition, accompanied by small amounts of other pigments that provide colour. Lower quality paints use other types of pigments such as talc, plaster, calcium carbonate or silica. Although they are initially opaque, they lack the durability that good products have.
- Binders are what make pigments stay well mixed once the paint dries. They allow a better adherence of the paint to the surface and also determine the durability of the paint.
- The solvent controls the consistency or texture of the product. In acrylic paints that are normally used to paint the wall, its solvent is water; in oily paints, mineral spirits or oil. Both evaporate when the paint dries.
- Additives: They are the chemical elements that improve the characteristics of the paint, increasing its resistance to mould and facilitating its application.
The quality of interior paint is determined by the amount of solid components that its formula incorporates or, in more technical terms, the ratio of resins and pigments to the other ingredients. That is, the more resins and pigments, the better the paint.
Quality paint has more solid components (pigments and resins) compared to solvents (water in plastic paints; mineral oils in oily ones). So when solvents evaporate, quality paint leaves a thicker, stronger layer on the wall.
Prime pigments. Prime pigments, such as titanium dioxide, provide better coverage. Quality white latex paint usually contains 20-25% of titanium dioxide.
The concentration of binders. A higher percentage of binders in the paint will improve performance by resisting cracking and peeling.
The price. If you are comparing different products in the range of the same manufacturer, the price is a good indicator of the different qualities of paint. Surely it has a Premium range and other simpler ones.
