Off-Topic

Off-Topic is a holding category for posts that don’t fit the main focus of this site.

Some of these articles still get occasional traffic or answer useful side questions, but they aren’t part of my core content around concrete, plaster/stucco, and masonry. Over time, I may update, reorganize, or move posts out of this category as the site becomes more focused.

If you’re here by accident, the best place to start is the Concrete or Render/Stucco categories.

Color Matching With a Spectrophotometer: What It Gets Right and Where It Still Misses

Introduction Color matching with a spectrophotometer is a tool that measures paint or stain color and gives you a recipe, but it isn’t a flawless substitute for a human eye on the job.
