Water-based or solvent-based enamel: differences, uses and many tips for use for painting wood, floors, walls, iron and other metals.

Enamel is a perfectly covering paint, it is suitable for painting any surface and on the market we find two different types: solventorwater. Let's immediately see the difference between these two products and the advantages and disadvantages of using one or the other.

They exist on the marketenamelsfor any purpose: thanks to the ability to cover a surface homogeneously, some glazes were created to paint the parquet floor in order to renew the appearance of the house without having to resort to deep renovations.

Difference between water-based enamel and solvent-based enamel

Theredifferenceit does not lie in the specific use, in fact on the market we find indifferently water-based or solvent-based enamels for wood, walls, iron and any type of metal. In some cases, these two glazes are interchangeable and both represent a valid choice but in others, the choice must be made based on the work you have to do. When to use solvent-based enamel and when to choose the water-based one? Let's see the answer together!

Solvent-based enamel

Solvent-based enamel is diluted with chemicals such as white oil or white spirit. Since the diluent used is rather aggressive, its use is recommended for external works.

Solvent-based enamel is suitable for external works when a surface is to be obtainedvery shinywith a "mirror" effect, or to paint the iron in poor condition without having to resort to preventive treatments.

Among its advantages, we mention that itsolvent-based enamelit returns a brighter color, which is why it is recommended for luminous and reflective finishes. They have a high understanding power and last a long time. This nail polish is easily cleaned with a damp cloth.

It is not without disadvantages: it has a very pungent and penetrating smell. Among its main disadvantages we mention that thesolvent-based enamelhas a negative impact on human health and the environment: these glazes release volatile organic compounds (the so-called VOCs) to the extent of 400 grams per liter. For thisNOTthey must be used indoors. If you really can't do without it and want to paint something at home with onesolvent-based enamel, remember to ventilate the premises well. Solvent-based nail polish dries much slower than water-based nail polish and, furthermore, the tools you have used must be thoroughly cleaned with white spirit otherwise they have to be thrown away.

Water-based enamel

TOdifferenceof thesolvent-based enamel, the water one is less aggressive and more tolerable for human health and the environment. It is not entirely exempt from the environmental impact, returning to talk about VOCs, thewater-based enamelsthey release 130 grams per liter.

They are more suitable for working indoors precisely because it is important to minimize the emissions of volatile organic compounds. They require more careful surface preparation but return better results when used on difficult materials such asplastic, aluminum or zinc.

Thewater-based enamelsthey have a less covering effect and therefore require an extra pass, they are effective on rusty iron without treatment but do not protect the iron from rust.

Thewater-based enamelit is odorless, dries quickly and is morepleasant to the touchwith respect tosolvent-based enamels. The maintenance of the tools is simple: the enamels are diluted with water so you just need to wash the roller and brush under hot water and then put them back in the toolbox.

Have you already painted a surface with water-based enamel and want to know if you can repaint it with solvent-based enamel or vice versa?
Yes, in both cases there is no problem, the water-based enamel can be passed on a surface painted with solvent-based enamel and vice versa and you do not need to perform any preparatory treatment.
