If we are going to repaint doors, windows, chairs, tables, fences or any surfaces that are already painted with solvent-based enamel, we can paint them with water-based enamel. To do this, we do not have to do anything special, we simply sand the surface and clean it with a cloth and solvent to remove possible traces of grease, dirt, cleaning resin, etc. And then we can calmly paint with water-based enamel.

How will you know if the surface is painted with solvent-based enamel?

You only need to know the approximate time of painting the surface. For example, if we buy a house and the door is painted and we want to repaint it, knowing how old the house is, we will know if it is solvent based enamel. If the door has been painted for more than 5 years, it is most likely a solvent-based enamel, as water-based enamel has been used for several years.

We can also know if it is a solvent-based enamel if the surface is painted with a special enamel, such as ferrite, martel, polyurethane, etc., because these enamels are solvent-only.

Paint with solvent-based enamel over water-based enamel.

If we want to paint with solvent-based enamel on top of water-based enamel, We won’t be able to because if we do, the solvent will lift and crack the water-based enamel layer.

The same goes for enamel coatings. You have them available for water and solvent.

Coat with water with solvent coating if applicable.

A solvent coating cannot be applied to an aqueous coating.
