Painting or staining your deck or porch is a rewarding DIY project that transforms your outdoor space. This guide shows you exactly what materials you'll need to buy and realistic 2026 pricing—so you can budget accurately and get started.
Estimated DIY materials cost for total materials for typical 200–400 sq ft deck or porch — you supply the labor. Prices vary by region and brand.
Across the full range this works out to $0.38–$4.00 per sq ft, depending on material grade and how much waste you plan for.
Here is the arithmetic, so you can redo it with your own numbers: a typical project here is 200–400 sq ft and runs $150–$800 in materials. Divide the middle of that cost range by the middle of the area range ($450 ÷ 300 sq ft) and you get $1.50 per sq ft. Measure your own space, multiply, and you have your materials budget.
Materials only — labour is not included. See what a contractor charges below.
This is beginner-friendly — a confident DIYer can usually handle it and keep the labor savings. The pro figure is a rough rule of thumb (labor on jobs like this often runs 1–2.5× the materials) — always get real quotes. It is not a NailIt estimate.
NailIt estimates materials only, so here is the honest version of the labour question rather than a number we cannot stand behind. Installed, this job commonly lands somewhere around $300–$2,800 — that is the materials range above with labour applied at the rough 1–2.5× multiplier trades typically work to on jobs like this. It is a sanity check for reading a quote, not a NailIt estimate and not a substitute for a real one.
What actually moves that number: your region and local labour rates, access and prep work, whether a permit and inspection are involved, disposal of the old material, and how much the crew has to work around your schedule. For this project the DIY route is realistic for most homeowners, and the labour saving is the whole point. Always collect three written quotes from licensed, insured contractors and compare what each one includes — how we handle pricing.

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.
