Paint & Stain Buying Tips
Always buy all your paint at once to ensure consistent color across the project. Different batches can have slight tint variations. When in doubt, buy an extra gallon — you'll need it for touch-ups down the road.
Premium paints ($40–$65/gallon) provide better coverage and durability than budget options ($25–$35). You often need fewer coats, which saves time and can actually cost less overall.
