Affect Property Values
Cracking and Flaking
Home and business owners have many good reasons to keep their properties structurally sound and visually appealing:
-
Properly applied coats of paint protect underlying wood, masonry, or metal surfaces from contaminants and water, contributing to the long-term durability of buildings.
-
Professionally applied paint helps property owners maintain or raise the value of their holdings.
By contrast, those who apply sealants at the wrong times or in the wrong ways can expose their properties and their work to the ravages of paint failure, including cracked and flaked paint.

Prevention
Cracking and Flaking
Prevent the onset of paint cracking and flaking:
-
Improperly prepped surfaces, like wood or brick, may harbor moisture that can make it hard for paint to adhere to walls. Avoid poor paint adhesion by properly cleaning and prepping walls, wood and brick surfaces before painting.
-
Use the correct primer for the project. Alkyd primer is a high-adhesion paint-primer, popular with building professionals. This kind of priming-liquid can adhere to many different materials, including metal, masonry, and wood. It is also useful for priming pre-painted surfaces, and builders who plan to apply oil-based paints over latex sub coats should always consider using alkyd primers on the latex first.
-
Do not dilute paint by adding too much thinner.
-
Do not apply overly thin layers of paint to walls and other surfaces.
-
If the weather conditions are too hot or too cold when paint is applied, this could lead to eventual cracking or flaking. Always apply paint when favorable weather conditions prevail.
