Have you painted your wooden furniture? Would you like to know whether they need more protection? To protect painted wooden furniture, products can be applied to enhance the protection of the wood. In this article, we will tell you about protective varnishes for painted wooden furniture, their usefulness and how to apply them.
Colourless wood varnishes protect the substrate from external influences such as stagnant water, stains or scratches. These products form a light film on the surface of the wood. This prevents water or greasy foodstuffs, for example, from penetrating into the wood, staining or damaging it. The wood paint underneath the varnish is therefore perfectly protected. In order to increase the protection of painted wooden furniture, we recommend that you varnish it when it is subjected to heavy use (repeated exposure to fatty foods, water, etc.). Putting clear varnish on painted wooden furniture is the best solution for high protection while preserving the initial rendering of the paint.
These varnishes also make it easier to clean painted wooden furniture. Wood paints, especially those with a matt finish, tend to fix dust. Applying a varnish on top of a paintwork helps the cleaning and maintenance of the furniture. By forming a film, painted wooden furniture becomes more washable. It can then be cleaned very easily with a cloth.
These products also provide paint protection for wooden furniture. By creating a light film, the varnishes protect the colour of the paint from the light. They prevent the paint from yellowing over time.
For the choice of the finish, a glossy wood furniture varnish will slightly intensify the colour of your paint but will also reveal the roughness of the furniture. A matt wood varnish will offer protection to the painted wooden furniture without making it shine. The paint will then be more matt even if it was shiny to begin with. The choice of protective varnish for wood paint therefore depends mainly on the finish you wish to obtain.
Within the Anova Bois range, you will find protective varnishes for wood paints. If you wish to varnish a piece of painted wood furniture that is in a very humid room (kitchen, bathroom), we recommend the Worktop Varnish VPT500. This varnish offers a reinforced protection against humidity. For a furniture that is less stressed, such as a decorative piece of furniture for example, the Furniture Varnish VM500 is perfectly suitable.
To apply a protective varnish for painted wooden furniture, you need to remove the old varnish if there is one. Otherwise (painted wooden furniture without any additional finish), you can apply the varnish to the previously cleaned and dusted wood. The varnish is applied in 2 to 3 coats in the direction of the wood fibres with a brush or roller.
After the first coat, the wood varnish should be lightly gritted with fine sandpaper (120 grain). This will remove any defects (air bubbles, dust, etc.) that are visible during the application of the first coat of varnish. After this light ginning, you will obtain a perfectly smooth appearance.
Apply the following coats (2 to 3 coats). Depending on the protection you wish to achieve, you can apply a third coat, for example on painted wooden furniture in a damp room.
