When power mixing, reduce the splattering by putting the container in a large trash bag.
One of the most important things to be aware of is that paint is formulated for either interior use or exterior use, and they have different properties: Interior paint is formulated for: Scrubbability and stain resistance; Good hiding ability; Splatter resistance; Easy touch-up. Exterior paint is formulated for: Color retention; Resistance to fading; Flexibility to withstand expansion and contraction due to weather; To provide a mildew resistant coating; Resistance to tannin bleed. Don't think that you should use exterior paints indoors on the assumption that it is "tougher". In fact, some of the highest-grade exterior paints can be worse to use indoors than a lower-quality interior paint.
Lead-based paint is usually not a hazard if it is in good consition, and it is not an impact or friction surface, like a window. It is defined by the federal government as paint with lead levels greater that or equal to 1.0 milligram per square centimeter, or more than .5% by weight.
Using a power drill and paddle attachment mechanizes the job of stirring paint, but it can cause splatters. One way to solve the problem is to use a paper plate. Punch a hole in the center of the plate and push the end of the paddle attachment through the hole before chucking it into your drill. Then hold the plate down over the open can while stirring.
Latex paint makes clean-up simple and fast: Clean any spills with a damp paper towel before they dry; Clean brushes, rollers and other tools with soap and water; Brushes should be paper-wrapped in a manner that retains their original shape before storing.
To reduce your child's exposure to lead, get your child checked, have your home tested (especially if your home has paint in poor condition and was built before 1978), and fix any hazards you may have. Children's blood lead levels tend to increase rapidly from 6 to 12 months of age, and tend to peak at 18 to 24 months of age.
Use the right solvent to clean up paint equipment. Check the paint can label. Generally use a mild detergent solution for water-based paints, mineral spirits for alkyd enamels, mineral spirits or turpentine for oil paints, alcohol for shellac, and mineral spirits for varnish. When you are reusing solvent for cleaning equipment, occasionally rub some between your fingers. When it begins to feel sticky, dispose of properly.
Oil-based (alkyd) paint must be removed from tools with brush cleaner or paint thinner. Pour the cleaning material into a clean bucket and rinse brushes and rollers well. When done, allow the solids to settle out of the cleaner, then strain the liquid back into the original container for reuse. Allow the settled solids to air-dry away from children, pets or open flames, then dispose of the container in the trash.
Lead dust can form when lead-based paint is dry scraped, dry sanded, or heated. Dust also forms when painted surfaces bump or rub together. Lead chips and dust can get on surfaces and objects that people touch. Settled lead dust can re-enter the air when people vacuum, sweep, or walk through it.
Even if your paint was mixed at the store, stir it thoroughly before each use. If it sits for a while during painting, it is best to give it a quick stir periodically.
