Editorial Standards

Who writes this site

I am the only writer and maintainer of PaintPro Calculator. There is no editorial team and no anonymous contributor pool. Questions and corrections come to the same inbox I use to maintain the calculator.

Sources I use

• Manufacturer technical data sheets (Sherwin-Williams, Behr, Benjamin Moore, PPG, Valspar, and others) for coverage rates, dry times, and application specs.
• EPA and state-level regulations for VOC limits, lead-paint disclosures, and disposal rules.
• Published cost data from RSMeans, HomeAdvisor, Angi, and direct retail pricing checked at Home Depot, Lowe's, and independent paint stores.
• Industry references including the Painting Contractors Association (PCA) and the Master Painters Institute (MPI).
• Original measurements taken on real projects, including my own home build.

What I don't do

• Republish or paraphrase content from other blogs without independent verification.
• Cite "industry experts" without naming them and linking to their work.
• Run sponsored posts or paid product placement disguised as recommendations.
• Take payment in exchange for ranking or inclusion in a "best of" list.

How I fact-check before publishing

This is the checklist I use for new work and for the older guides I am reviewing:

• Coverage rates, dry times, and application limits are checked against the current product label or technical data sheet.
• Products are checked for current availability. If I have not personally used one, I say so instead of implying a hands-on test.
• Useful primary sources are linked near the claim or in a source note.
• The draft gets a plain-language edit to remove filler and unsupported certainty.

Some older posts did not meet that standard. On July 11, 2026, I reduced the set submitted to search engines while I review the rest. Those older pages remain available, but they are not presented as finished reference material.

Update cycle

• Cost figures: reviewed quarterly. The "Last updated" date at the top of each article reflects the most recent review.
• Product recommendations: reviewed whenever a product is discontinued, reformulated, or replaced.
• Coverage rates and technical specs: reviewed when a manufacturer publishes a new data sheet.
• Regulatory information: reviewed annually or when EPA / state guidance changes.

Corrections

If I get something wrong, the correction is added at the top of the article in italics with the date of the change. The original error is acknowledged, not silently overwritten. To report an issue, email [email protected] and include the URL and the specific claim you're flagging.

Editorial independence

Affiliate links never determine what I recommend. If a higher-paying alternative is worse, the lower-paying one wins. If the best option has no affiliate program at all, I still link to it. Recommendations follow the work, not the commission.

What I'm qualified to say

I'm a homeowner who self-contracted his own house build, has painted many rooms, and reads paint manufacturer documentation for fun. I am not a licensed painter or a certified building inspector. The advice on this site is written for DIY homeowners and for people sanity-checking a contractor quote. For commercial work, fire-rated coatings, lead abatement, or anything that requires sign-off from a code inspector, hire a licensed professional.
