|Paint Tips and Hints|
|From Benjamin Moore... Historically, blues have been used to ward off wasps and other insects. I never heard of this before.|
One common problem with paint on concrete or brick surfaces is a condition of efflorescence, which is the white powdery stuff that appears to grow out of the concrete.|
"Efflorescence is an accumulation of minerals and salts on masonry surfaces, such as brick, cement, and sometimes stone. Inspectors should know how to prevent against and remove this unsightly residue. They must also be aware that, while efflorescence itself is not dangerous, it indicates the presence of excess water, which can lead to more serious structural and health issues.
