Never shut the HVAC system down completely - keep air circulating at all times. Vacuum carpeted areas frequently using vacuum cleaners equipped with HEPA filtration systems. Mop bare floors and vinyl floor-coverings frequently. Clean blinds, ceiling fan blades and HVAC return air vents frequently. The world of painting materials continues to evolve.
Health concerns are a continuous challenge and ease of application a primary goal.
Paints have now been prepackaged for ease of application, techniques for mixing and matching colors have simplified a once difficult task, harmful lead and mercury components have been eliminated, and the life span of the products has been extended. A few interesting developments deserve mentioning today. Although exterior painting was impractical during colder months, there are now exterior points that can be applied in temperatures below 40 degrees - extending paint seasons. The quality of new water borne enamels continues to improve and will soon replace alkyd or latex enamels. There are new points for bathrooms that have a guaranteed resistance to mold or mildew.
