The quality of materials used on your project will impact how it looks and how long it lasts. There is a huge difference in quality among coatings like paints and stains. There are also many specialized coatings that should be used for specific applications. Differences in the costs of a $9 gallon of paint versus a $50 gallon of paint represent real differences in the ingredients, with higher-priced paint having more expensive ingredients that look better and last longer, such as resins, binders and even titanium.
If you paint over dirty, oily surfaces, the paint will easily chip or peel off. So before painting, clean grimy areas with a deglosser or heavy-duty cleaner intended for prepaint cleaning. They work well to clean painted, varnished or enameled surfaces to improve the adhesion of the new paint. They’re ideal for cleaning greasy or oily areas like kitchen and bathroom walls and removing hand marks around light switches and doorknobs.
