Choosing the right type of paint can be just as important as picking a color. Some paints work a lot better for certain conditions than others.
One problem every home encounters is exposure to sunlight. UV rays will cause paint to fade, chalk, and lose its original tint. Latex paint tends to resist these effects better than oil-based paints.
Wood exposed to wet conditions will expand and contract, causing some paints to crack and flake. Latex paint allows moisture to vaporize and escape before it can damage the wood fibers.
Temperature change is another factor to consider, because drastic changes will also affect wooden surfaces and siding. Here again, acrylic latex is an ideal choice because it is slightly elastic, so it will deal with the stress of seasonal climate change without blistering or cracking.
