Pitfall # 2: poorly prepare its bracket before painting
When we want to repaint the walls, it is tempting to cut corners, to arrive as quickly as possible to the final result ... Error! For if we do not take care to prepare the surface for painting, we may obtain imperfect walls, revealing all defects.
Small reminder of the steps to follow: - If the painting surface is dirty (grease, grime, nicotine, fingerprints ...), it will wash it with a mild detergent diluted in water, always ending with a clear water rinse and a complete drying. Attention walls should always be washed from the bottom up to avoid dirty drips. - If cracks are visible on the surface to be painted, it will open with a triangular scraper and reseal carefully to the coating, and finish by sanding, once the dry coating. If the cracks are too important because " alive " (Due to variations in materials, they then receive the entire thickness of the plaster or wall), it is conceivable to put a glass cloth composed of very strong fibers and presented in rolls, prior to painting. The cracks will be much longer to reappear. Please note that the first layer of paint applied to a glass cloth must always be an acrylic painting that will not damage the coating. If you opt for this choice, avoid paper to paint reliefs and settle you a smooth surface, always reliable. Latest of painted paper, support for new arises like wallpaper and replaces the sandpaper. Smooth, it offers the possibility to apply a layer of paint on top, single or effect. - If the old paint is peeling, it will remove the loose paint with a stiff wire brush and then sand the surface with a medium-grit sandpaper, then fine grain.

Example: my part has a perimeter (5m + 7m) x 2 = 24m x 2.50m ceiling height = 60 m2.

A good brush should be tapered and have long securely fastened to the handle hair, it is better to choose raw wood (instead of plastic or painted wood) for better grip. Better use of synthetic bristles when painted with an aqueous emulsion-based paint, said water-based paint. However, wool and silk are recommended when using solvent paint, alkyd said. Again, do not hesitate to ask the sellers specialty stores, they will direct you to the right products.
Rolls-pile will be reserved for bright lacquers and paints, models with short or medium length hair will be perfect for satin and matte, anti-drops will be essential for ceilings. Finally, a large enough pan together with a grid will drain the excess paint before moving the roller. For baseboards and all flat surfaces, it is best to use flat brushes. However, use round brushes to paint the moldings and wall corners. As for the radiators, the corners are not easy to access, they will make it mandatory to use special brushes, elbow and long sleeve.

Pitfall # 5: Get started without having tried his mural
The choice of the color of a painting always proves tricky. What shade adopt out where the place, how it fits together to the room and it creates the right mood? These questions require real reflection. Recently, virtual simulators and color charts are used to test the colors at home. The rendering is often artificial and far from offering the delicacy of colors and halftones. Hence the need to check at home the tone selected using samples before embarking on big jobs. The quality paints, as Farrow&Ball or Resource, and recently the DIY stores such as Leroy Merlin or brands such as Dulux Valentine, offer for sale of small pots called 100ml " testers " that can be a pretty fair idea of the desired shade. Rather than applying the tester directly on the wall or part painting, better carry out tests on a white cardboard 50x50 cm, and then placing it in different places in the room and at different times of the day including night by electric light.
These preliminary tests prove essential when one wishes to apply halftone or light tones, which undergo more than strong colors the influences of the environment and that can actually change appearance depending on the circumstances.

In addition, it is likely to yellow with age, and its drying time is long enough between two layers.
Watercolor and acrylic. Acrylic paint, said " water color ", Is odorless and virtually contains little organic solvents harmful to the environment. Above all, there are now excellent Language @ acrylics in terms of rendering and texture. Easy to apply, it spreads easily, dries quickly and holds in any medium. It is washable and tools can be cleaned with water. His only fault: it is weaker than its " rival " glycerophthalic.
And that's not all ! Youngest paint radius, alkyd aqueous emulsion has the advantages of alkyd (resistance and tense appearance, high coverage) without its drawbacks (no smell, shorter drying, no yellowing). Tip: for not choosing an inadequate quality, ask yourself the following questions: are we going to paint the walls yourself? Are sensitive people may inhale paint? The work will be carried out while they are already living here? If the answer is yes to all three questions, we unhesitatingly opt for a painting in aqueous emulsion.
