Blistering and peeling Paint!

Blistering and peeling are almost always caused by moisture, either moisture vapour or actual moisture, usually water.
During the winter months, excess moisture building up inside the house escapes through walls and into exterior paint. When the summer sun heats the siding, water trapped inside the paint film is vaporized with the resulting pressure causing the topcoat to blister.
But how do you prevent this?
To fix the blistered spots in the paint on your house, you will need to scrape the blisters off. If the bare spots are very noticeable, you will need to sand them down flush with a fine grade of sandpaper. You will then need to use a good - quality primer to undercoat the bare areas. Follow the manufacturer's directions on the container in order to achieve the best results. However, it would be a good idea to let the primer dry thoroughly for a day or two. Then, follow that with a couple coats of good, quality paint.
