Any spills are immediately and thoroughly removed. It is recommended that you have someone do a thorough cleaning after I have left. I regularly use materials from Sherwin Williams, Coronado, Benjamin Moore, Duron and Olympic. Which company I use on your project is determined by your preference, location of project, nature of work to be accomplished, length of warrantee required. Well, you can ask a hundred painters and get a hundred answers.
Most manufacturers have a high and low grade of paint.
Never compromise and use a low grade just to get a cheaper estimate for your project, unless circumstances are such that you don't need the highest quality. Restrictions imposed on paint manufacturers by the EPA has resulted in the removal of the lead content and the amount of solvent or vehicle contained in oil-base enamels. Consequently, the performance of oil-base enamel has suffered. Improvements in acrylic, water borne paint technology has, at the same time, improved substantially. The result is a quick drying acrylic-latex paint which levels well, cleans up with water, and can stand up to severe wear and tear.
