The below project was painted by students 2 years before we had to repaint it. When built it was originally painted with oil. A water-based paint, we believe to have been an interior product had been applied by the students. It resulted in 100% failure. We grinded the entire house, we applied an exterior oil primer and top coated 3 times with A100, the last coat was a breeze coat to smooth out the finish. This paint job will last 15 years plus. This is one of the many corrections I have completed over the years. The brown door image to the above right was the front door, I decided to remove it, completely strip it and refinish with an exterior wood stain to suit the completed paint job.
Below was a home where we carried out much the same process as above. Although I did not price the job for it, we again used a grinder on the the entire home. We applied Fresh Start oil primer which created an excellent base and top coated with Benjamin Moore. This job will last for 15 years plus. 3 coats are necessary for such work and an oil priming is by far the most effective way of ensuring the home receives a good base for the final top coats. We have completed many large and smaller heritage homes this way over the years.
