There are many reasons why choosing exterior paint can be a bit difficult. One of them is because the wide range of surfaces. The surfaces are usually made from clapboard and aluminum siding, wood shingles, tar shingles, cedar shakes, brick, concrete block, stucco, and, of course, old paint.
On some houses, especially on many older homes, you’ll find a combination of these surfaces. But don’t worry as you can find many exterior paints that are designed for every type of surface, and some paints are suitable for more than one surface. So, you only need to choose the right paint type and you are ready to paint it with your airless paint sprayer, brush or whatever you want.
Moreover, you can also find exterior paints available in either water-thinned or solvent thinned formulas and in three lusters: flat, semi-gloss, and gloss, just like the interior paints. However, for some reasons exterior paint is more expensive and they also contain more resin for moisture resistance and durability and pigment for color.
Most people usually want to use the same exterior paint based on what was used before. This makes sense, as latex works best over latex and alkyd works best over alkyd. But, you can use an alkyd-based paint if you are unsure about what type of paint is on the house.
Here are some advantages and disadvantages of each type of some exterior paints:
Latex Exterior Paint
If you are looking for a paint that are easier to apply, dry quickly, and can help minimize moisture problems because they “breathe”, latex is the best choice. However, latex does not adhere as well to oil-base or alkyd-based paints or to poorly prepared surfaces.
Alkyds Exterior Paint
Alkyd is best known as extremely durable paint, but at some point they are more difficult to work with and they dry slowly. Moreover, you may need solvents to clean brushes, rollers, paint trays, and drips. One of the alkyd types of exterior paint may be especially appealing because of its regulated, self-cleaning property. This called “chalking”, and that’s exactly what it does. After years, the paint surface slowly oxidizes and each rainfall washes off a minute quantity of the paint – along with dirt.
Chalking paint is unpopular for every house; this is because in areas with little rainfall, the powder tends to remain on the surface. But, the chalking paint may be suitable to be applied in wet regions as rainfalls will keep the outside of the house clean no matter what kind of paint is used.
