Painting your house is very important, there are a lot of reasons why we should consider painting as one of the most crucial part of maintaining our homes. By painting your house you are beautifying your home, add character to it, and most important reason of all you are protecting your house against the weather, insects and other damages. In that sense it is necessary to take enough time planning what colors, shades, and paint styles you want to use for your home. There is no timeline for when you should repaint your house. It depends on the quality of the previous painting job made at the same time the quality of the paint that has been used. Substandard paint job can only last for three years or less before it needs another painting job. Good quality paint jobs can last for twenty years and up. But sometimes some of us are just ready to make a sudden change and it doesn’t matter as long as we are doing the proper way of painting our houses.
Primarily, all paints are formulated with the use of similar main ingredients like solvents, resins, additives and pigments. But, the paints that are formulated for interior at the same time for the exterior surfaces are not the same as the environment to which they are exposed to are different. Different surfaces require different properties, and different paints have different properties and are prepared to suit different purposes.
All paints are produced from the four main ingredients: solvents, resin, additives and pigments. Interior and exterior paints have the same solvents and pigments, but exterior paint may contain more pigments. The main distinction between interior and exterior paint can be found in the additives and resins. To know the difference between interior and exterior paint, you need to understand the paint chemistry.
Painting outside the house requires a lot before you can proceed and start the project. You should wait for the warm weather. Since most exterior paint needs an ambient temperature of about 50 degrees Fahrenheit, waiting until the summer season truly starts in June, July, August, or early September will give you the best outcome.
Avoid the rain, check the weather when the highest rainfall and snow will be and make sure not to paint on those seasons. Holding off until dry season starts before doing an exterior paint job allows your home’s siding a tendency to dry out after winter snow and spring rain. A siding that is saturated with water can weaken paint’s ability to dry properly, but some professional painting contractors can identify when your siding’s moisture has reached a feasible level. Contractors should also know when wet weather is on the horizon and can avoid it as necessary.
Find ideal conditions, summer is the best time for painting because it is dry and warm. Not everyone can do the painting job over summer because of their schedule, other homeowners tend to do it during late fall or early spring. Some contractors extend the painting season as much as possible. Best quality painting contractors know that it is important to paint in times when the weather conditions are stable and temperatures does not change remarkably overnight or from day to day.
Do not compromise the quality just to save your time and budget. You should take the necessary time to do the job right. This means taking additional time to scrape, sand, and prime your home’s exterior prior to painting. Know the difference between latex, oil, and acrylic exterior paints and it can help you choose the right type and proper color to make your home’s exterior look great for longer period of time. Take note of this as well, if you are going to paint using latex the ideal temperature is between 50 and 85 degrees Fahrenheit. For oil-based paint is within 40 to 90 degrees Fahrenheit. In terms of corresponding humidity, 40 to 70 percent is ideal for drying paint.
Here are the characteristics of exterior paint, this can give you enough idea to get the results that you are aiming for.
Exterior paint is exposed to all types of weather conditions. Exterior paint is needed to provide protection against Ultraviolet radiation of the sun as well as fungal growth and of course wetness during the rain and snow falls. Exterior paints are made to resist mildew as well as fading. Moreover, it has to be fade resistant as it faces very high temperatures and UV radiation. Resins that are used for exterior paint can be softer so that the paint can survive varying temperature and damaging effects because of exposure to moisture. Exterior paint is tougher and capable of resisting peeling and chipping. It can resist water therefor it is made to be waterproof. Exterior paint needs direct sunlight for its curing process. It also contains many additives like pesticides and fungicides. During curing process the paint releases more VOC, one reasons why exterior paint is not safe to use for interior painting. If it rains the exterior walls of your house acts as a sponge, it absorbs a small amount of water. While flat paint allows the water to escape without bubbling your paint.
It can be too cold to paint the outside, but the weather can't keep you from doing some serious interior paint work on even the coldest winter days. Interior painting is just the same whether in summer or winter. The weather may be cooler, even inside, but that's not a problem. The paint smell can even be lessened. Whatever the weather is, ventilation is important whenever you paint. The interior paint is more on aesthetic and decorative purposes, and they also need to add properties of easy maintenance, wash ability and dampness prevention. Interior paint is made to resist abrasion. Interior paint is also produced to be more delicate compared to exterior paint because it occupies a similar space as you do. One of its purpose is to be easily scrubbed and resist stains. It is more resistant to physical damage. Resins in interior paints are firmer because it doesn’t need to deal with the harsh weather and temperature. It doesn't need to be fade resistant because it doesn’t deal with extreme temperature and weather conditions, so it doesn’t fade easily. It can be cured even without direct sunlight exposure. It is required for interior paints to be stain resistant to hide marks from the brush and rollers.
Unlike exterior paint, it does not require additives like pesticides and fungicides and interior paint is washable so it would be easier to clean spots and marks especially when there are small kids and pets at home. Interior paint should have a low or zero VOC (Volatile organic compounds). This is important in preserving the air quality in your home. Low or zero-VOC help to reduce your health risks. Even though the interior and exterior paints look similar, they differ on the bases of their properties, purposes and uses and that one cannot be used in place of another. Just like you can’t use interior paints on exterior surfaces and vice versa. Make sure that you check the label when you purchase one.
