Always buy 10-15% more paint than calculated to account for touch-ups, spills, and future maintenance. Consider the surface texture and condition - rough or porous surfaces will require more paint than smooth ones. Test your paint color on a small area first, as colors can look different under various lighting conditions. Remember that proper surface preparation is crucial for a professional finish and can actually save paint by ensuring better coverage and adhesion.
