Stucco is a cement lime based product. Often, when it rains you can see a “cloud” effect on stucco. Water penetrates stucco because it is concrete based and absorbs water. Thus, stucco dries from the inside out.
RE-STUCCO, PATCH, OR REPAINT
Most of the time, our team only has to repaint the stucco. Sometimes however, our team will first need to either re-stucco or patch stucco cracks before painting. If more than 50% of the stucco is cracking or falling off, we suggest to sandblast and re-stucco the surface. If it is not necessary to re-stucco, we patch all the stucco cracks, prime, and seal the surface. With the finish coat, the stucco is sealed and when water hits, it will drain quicker and won’t absorb as much moisture.
Primer is formulated to prime or seal stucco or wood. It is of the utmost importance that stucco is primed before it is painted. This step is only necessary if the stucco hasn’t been painted before. Not all homes need to be primed, it all depends on the condition of the home. We first fix the cracks, prime the areas that need it, then add the finish coat.
Wood siding, fascia board, and trim are some of the other materials we come across when painting exteriors. Old houses often have oil based paint while newer houses commonly have water based paint. Some paints are a mixture of both.
If there is an existing oil based paint on a surface, you can’t put a water based paint on top of it. The surface needs to be primed first. The oil based paint needs to be sanded off. In some cases, the paint needs to be sanded all the way down to the wood.
