Painting A Surface
Where to start? You start with the fact that the paint and the painted surface in terms of physical and chemical properties must be compatible with each another. Each facade material for best results requires its own color. Before starting the work necessary to determine the type of surface and analyze its condition, because the surface characteristics determine the requirements for one or another form of paints and varnishes. For example, for the concrete surfaces of paint used must be weather-and alkali-resistant, for timber – water-resistant, Elastic and non-combustible, for metal – are necessary corrosion resistance and moisture resistance. In addition, if the surface has been previously painted, then it is necessary to determine the composition of old paint.
If they are not compatible, the result may turn out the most unpredictable. Once defined the type of surface, it is very important to evaluate quality and to prepare the base before applying the cladding coating. Training surface includes the cleaning, degreasing, hardening impregnation, finishing leveling, and in conclusion – the opaque coating primer to equalize the color and improve the adhesion (bond) to paint. It should be remembered that the only good-quality surface preparation will provide a quality finished surface. It is known that the appearance and durability of facade coatings depend on: 60% – from surface preparation; 10-15% – of the correctness of the paint; 25-30% – on the quality of the paint itself.
Selecting the type of facade paints for exterior paint binder divided into three groups: acrylic paint, silicate paint, latex and silicone paint. To date, the world's leading paint facade materials are acrylic coatings – paints, primers, enamels, fillers. The main advantages of acrylic materials – durable and reliable protection of covered surfaces. It is worth to underline the fact that the acrylic coating (unlike oil, alkyd, silicone, etc.) and has the ability to flexibly "Breathe".
