Peeling paint
Understanding Peeling Paint
Paint bubbling, also known as paint blistering, occurs when paint starts lifting from a surface. These terms are used interchangeably.
Such imperfections can affect the appearance of a finished painting project.
Causes of Paint Bubbling and Blistering
Several factors can cause paint bubbling. Common culprits include surface contamination, improper cleaning, environmental conditions, and incompatible additives.
Surface contamination refers to painting over areas with oil, wax, grease, or silicone. Improper cleaning is also a contributing factor.
Peeling Paint and Lead Hazards
In 1978, the federal government banned the sale of lead-based paint for use in homes, childcare facilities, and preschools. Approximately three-quarters of U.S. homes built before 1978 may still contain some lead-based paint.
When painted surfaces are not maintained, lead-based paint can deteriorate, peel, chip, or crack, potentially becoming a hazard.
Old or worn lead-based paint, especially on surfaces subject to constant friction like doors or window sills, can produce hazardous chips and dust. Renovation, repair, or painting projects in these older homes can easily create dangerous lead dust.
Estimating Paint Needs
Accurately calculating the amount of paint required is a crucial step when planning any painting project.
