I take care of all my work. And I make sure that the oil paintings are protected from the harmful effects of sunlight and dust.
And so I coat all my work with varnish. The procedure is recommended to be repeated approximately every 5 years, since over time, the varnish is absorbed a little and the picture loses a uniform matte sheen.
Anyone who has my work can contact me and ask TOTALLY FREE to process the painting with topcoat. Even if the job came to you 5 or 10 years ago.
I take care and follow each of my work, despite the limitations of its writing and the current location.
