Paint sits on the surface and offers more color options and UV protection, while stain soaks into wood and enhances the grain. Stain typically lasts 1–3 years; paint lasts 2–5 years. Stain is usually cheaper per gallon but may require more frequent recoating.
Primer is recommended for bare or newly sanded wood to improve paint adhesion and coverage. Many modern deck paints are self-priming, so check the label. If recoating previously painted surfaces in good condition, primer may not be necessary.
Most deck paints cover 200–400 sq ft per gallon depending on texture and porosity. Measure your deck or porch square footage, then divide by the coverage rate on the paint can. Buy an extra half-gallon for touch-ups and waste.
