What changed

This page records what changed on the site and in the guides, with the date. When a law, a rule or a data sheet changes and we update a guide, we write here what was changed and why. If you find a mistake or something out of date, tell us through the contact page.

First version of the site, with this content:

• Paint calculator on the home page: it draws the room and works out the area to paint and the litres of paint. How it works is in the methodology.
• Wall form, to describe your case and leave your contact details. At the moment we do not forward requests to painters.
• Legal and transparency pages: privacy policy, cookie policy, terms of use, methodology and about the project. Google Analytics is switched on only if you accept the analytics cookies.
• First structure of the site. The guides on preparation, paints, damp, mould, salt deposits, condominiums, renting and choosing a painter come next, and each one will be recorded here.
• English version, for people living in Portugal who do not read Portuguese.
• Plain-text copy of every page (add .md to the address) and a map for AI assistants at /llms.txt, with the access rules in robots.txt. The content may be read and cited by search and AI assistants, but not used to train models.

How we record changes

• A change that alters what the reader should do (a deadline, an amount, a rule) is recorded here, with the date.
• Corrections of typos and links are not recorded.
• Every guide shows the date of its last review at the top.
