Lap marks are those ugly stripes caused by uneven layers of paint buildup. They occur when you roll over paint that’s already partly dry. (In warm, dry conditions, latex paint can begin to stiffen in less than a minute!) The key to avoiding lap marks  when doing DIY wall painting is to maintain a “wet edge,” so each stroke of your roller overlaps the previous stroke before the paint can begin to dry.

Federal law requires all renovation, repair, and painting firms (including sole proprietorships) working in housing, or facilities where children are routinely present, built before 1978, to be certified. Firm certification is a key requirement to ensure the training of individuals and the use of lead-safe work practices.  Firms must apply to EPA for certification to perform renovations or dust sampling. To apply, a firm must submit a completed application and fee to EPA online. 
Stucco is a specialized material that requires extensive preparation work (cleaning, caulking, filling in cracks, etc.). Additionally, paint suitable for rolling or brushing over stucco varies greatly depending on location and climate conditions. Some stucco paint varieties will chip and peel away in certain climate conditions, so painting professionals won't recommend them. These factors make stucco one of the more expensive siding materials to cover. You can expect to pay anywhere from $900 (~500 sq. ft.) to $3,000 (~1,500 sq. ft.) to have stucco revitalized with paint, depending on how much is needed to cover the home exterior.
