What Is the Most Durable Paint – The Factors to Consider

If you want to know what is the most durable paint, then you should read on! Almost every household has paint residues in buckets, cans, or other containers. However, the durability of paint is not the same – this applies to emulsion paints, varnishes, and glazes.

How long these paints last depends on a number of factors. What these are, how best to store paints, and how to detect bad paint, this article reveals.

What Is the Most Durable Paint

Durability of Unopened Paints, Varnishes, and Glazes

On the label of a paint, varnish, or glaze container, you can find information on the durability of the paint in some cases – and if so, the date before you open it.

Even though most manufacturers state a two-year shelf life for their paints, varnishes, and glazes, in practice, these last five to ten years without spoiling. Note that this is the durability of the paint before you open it.

Paint usually lasts significantly longer than the label states. You can stir sunk components such as pigments and fillers, relatively easily.

However, if the paint is bad- this is relatively easy to detect. The next paragraph tells us how!

Detecting Bad Color

If the paint is past its shelf life,  it emits a bad smell after opening the container. Then, it is important to close the paint bucket as quickly as possible, and dispose the hazardous waste.

If there is only a thin, liquid layer on the actual paint without any sign of mold or bad smell, then you can stir up the paint.

Smaller and dry cracks on the walls of the paint bucket are not too bad, but you should not stir them in. In case there are large dry layers, for example, due to a leak, then you can no longer use the paint.

On the other hand, if the paint thickens so much that you cannot stir it, you should realize it is past its shelf life. There is unfortunately no other choice but to dispose the paint.

What Is the Most Durable Paint – The Correct Storage of Paint

In addition to the quality of the products, correct storage is also responsible for the durability of paints, varnishes, and glazes.

For this reason, you should press the lid tightly immediately after you complete the painting work. It will ensure the container is as airtight as possible.

Moreover, you should store the paint in optimal storage conditions in the cellar, in a uniformly tempered and cool place.

However, do not store them too cool, because the products do not tolerate frost. Once frozen, it is sufficient to set the shelf life of the paint products to zero.

Shelf Life of Emulsion Paints

The durability of emulsion paints is different from the durability of varnishes and glazes. As a rule, dispersion paints do not have any preservatives. It means the durability of the paint continuously decreases after opening the paint bucket.

The bacteria and germs that you introduce into the paint by the brush or paint roller slowly decompose the ingredients. The decomposition begins with the binder and continues with the pigments.

This decomposition causes the paint to lose its properties, such as viscosity, smudge resistance, wall adhesion, or spreadability.

All too cheap dispersion paints usually “age” faster, as they tend to have a weak binder or poor quality pigments.

Since decomposition is a slow process, you can significantly extend the durability of the paint by working cleanly. Moreover, seal it immediately and store it upright, in a cool and constant temperature, after you complete your project.

Durability of Paints and Varnishes

Acrylic lacquers and water-based glazes last significantly longer than solvent-based products. However, the reason for this is not the faster decomposition, but the fact that solvents evaporate much faster.

With a little tip, however, the durability of these paints can also be extended considerably.

To do this, take care not to deform the lid when opening the paint or glaze can. Furthermore, when you complete the project, close the container again so that it is airtight. Keep in mind that airtight does not mean sealing the lid with silicone, but simply turning the can upside down.

Lacquers and glazes are therefore always stored in appropriately large tubs, which can easily absorb the paint in case of a leak.

This little trick is already enough to significantly extend the durability of solvent-based paints.

Tip: If a thin skin nevertheless forms on the paint or glaze, remove it carefully. Then sieve the paint through a stocking into another container. In this way, the thick substances remain in the stocking and you can still use the varnish after stirring.

Conclusion – What Is the Most Durable Paint

The durability of paint often lasts much longer than the manufacturer specifies, especially before you open it. You can recognize poor paint by its bad smell and by its lack of miscibility.

So throwing away old but still good paint is not only throwing away money, but it also pollutes our environment. If you properly seal-the products and store them in a cool, evenly tempered place, nothing stands in the way of their use even after two to five years.
