Time Status And Application Of Paint
Temperature, humidity and wind are factors you should consider not to affect the good adhesion and paint finish.
The heat should not be excessive
It is recommended not to paint the sun. The direct effect of sunlight on surfaces causes them to acquire high temperatures that impair adhesion of the material. The solvent with which they are dissolved evaporates quickly producing an immediate drying and avoiding penetration into the surface, causing air bubbles or blisters almost immediately after applying. This is seen more frequently in oil paints and synthetic enamels and varnishes. For water-based paints may occur cracking of the layer of material applied to the wall. Therefore it is recommended facades and exterior paint in the shade or morning or evening. It should take into account the heat in the painting of swimming pools, where it is advisable to work on dry days with temperatures between 10 º and 25 º.
As the environmental humidity affect the paint
In the case of excessive humidity, condensation occurs on the surface wetting and adhesion difficult material applied, especially in the case of oil paints. Never paint when rain is approaching.
The wind and dust particles
The difficulty imposed by the wind is obvious. The adhesion of dust and dirt particles from the surface soil and give you a rough finish. This is less evident during the hell out of walls but seriously affected carpentry as door, windows and surfaces exposed to the touch.
