Hello all! My name is Dulce and I just joined the site. I am painting a mural in a school, using latex and acrylic paints, and I need to find a varnish to protect it. Despite being indoors, there are some skylights that allow the sunlight hit the walls for a few minutes and also I am concerned about the fluorescent lights that also tend to fade the colors. In the previous works I have used the Behr Crystal Clear Water Based Polyurethane no. 780, but it was discontinued. I am looking for some product with UV filter in a flat finish. Does anyone know any product that fits this profile? Thanks.
