Painting in Condition for Your Climate


Painting Conditions for Your Climate


The need for good weather is an essential condition for effective painting, and a warm dry climate is the perfect weather for painting. This usually happens during the spring, summer and autumn. Throughout these periods of the year, humidity, rains and strong winds are infrequent in the not too distant past. Painters had to wait for fine dry weather to a paint house. Consequently, interior residential painting was a seasonal project. Nonetheless, the development of technology, rivalry and an urgent need have made it practicable to paint houses at any time of the year except during intense weather conditions like high winds, heavy rains and frosty weather.

There are numerous areas in the world where the local climate is diverse and sometimes fickle. For example, one country may have a tropical northern area and a temperate southern region during the same period of the year. There are also places that have short summers and long winters and vice versa. Even so, many others endure unusual rainfalls during the summer time. Painters need to strengthen themselves up with effective techniques to resist the changing weather conditions in their particular areas so that they can continue in business throughout the year. Particularly, they need to know how to paint productively during hot or cold-weather surroundings and not just depend on the perfect weather for painting.


Cold Weather Painting


The two most commonplace types of paint are Acrylic and oil. Acrylic is paintable in temperatures no lower than 5 'Celsius while oil can only withstand temperatures no lower than 10' Celsius. Below these temperatures, high moisture levels can cause blotches, clouding, cracking, undesirable shadows or unappealing colours and significantly longer drying time. It is important to remark now that the temperature we speak of here is applicable to the air temperature. You also have to think ahead and consider what the air temperature is going to be in a few hour's time or overnight.
The weather may be fine and suitable for painting during the middle
of the day but oil-based paints usually need 12 hours to dry, and an unforeseen cold night can give problems in the morning. The substrate and the paint itself. The substrate is the object on which paint is applied.

Hot Weather Painting


Similar to cold weather, effectual painting during hotter conditions require the correct air temperature, the substrate and the paint. Many painters will confirm that air and substrate temperatures higher than 30' Celsius can significantly affect the proper establishment of the paint film. Excessively hot environment can also cause pin holes and lap marks during application while direct sun exposure can start blisters on the paint film. During the hotter summer periods, painting can best be done in the earlier and later in the day. Hot paint also inclines to flow unevenly leaving an un even surface finish.

Most Professional painters are fastidious about the quality of paint they use, particularly in places with unexpected weather patterns. Colour fastness, durability and wash ability is the test of good-quality paint. In order to preserve colour longer, the paint needs to contain more pigments than liquid or fillers, elements that are added just to increase volume. The binder should be of quality material so that the pigment particle's form into a uniform paint film that aggressively sticks to the substrate. All in all, quality paint makes for easier application, better hiding and protection and a more rewarding visible effect.
While most homeowners prefer to wait for the perfect weather for painting, the professional painter is fast acquiring techniques and skills so that they can continue to practice their profession the whole year round. Special equipment and tools, creativity and innovation have taken over many conventional methods that can be used limitedly during fine weather conditions.
