The bad sides of the glycero : she smells strong, remains harmful to the environment and cleans with white spirit. In contrast, the painting acrylic exterior, with dilution with water, releases very little VOC (volatile organic compounds) and less odor. It can be applied during the day, with 3 or 4 hours between two layers. "

On metal furniture, apply an underlayment rustproof. For shutters, it is best to have them sandblasted by a company that will remove the various layers of paint present. Once the media is ready to paint, an undercoat can be useful depending on the original color and the desired color. "

On shutters or furniture, the exterior color becomes lighter with time. "With the sun, the paint is skating," said Claire Delahaye of Slowgarden. "Better to choose the hue above the desired one."

"Between the all-gray and sunny days, climate variations offer a wide range of different lights, and the shadows will also create reflections on the paint," says Slowgarden's creator.

Like the rest of the house, the exterior painting can also be an opportunity to visually modify the space, to enlarge for example. "On small terraces or in the inner courtyards, it is better to avoid shades of greens that absorb light, warns Claire Delahaye.In a narrow garden, the color is found on a side wall or with a return on part of the wall to give an illusion of space In the same way, a very high wall can be "cut" by applying color only on the bottom of the wall. " Depending on the structure of the terrace or garden, enjoy the application of exterior paint to make the most of the space.
