i had a painting business back in the sixties and seventies . one thing i discovered is for the most part ,the thing that determines coverage with WHITE paint is the percentage of Titanium Dioxide in the paint . my partner and i did an unscientific test by comparing different brands with varying amounts of TD per gallon .The ones that covered the best had the highest percentage of TD . So, you can come to your own conclusions . however , because this was so long ago there may be newer factors that will improve coverage .
I believe that is still true about the TD. The amount of TD varies a lot in primers as well. If you are just sealing new drywall the cheaper stuff gets the job done, for hiding dark colors I spend a couple of dollars more for the extra TD to get superior hide.
I used Behr Marquee on a bedroom with a dark blue green paint and painted it a light gray-blue and was very happy with Behr Marquee After 1 coat it covered, but I always use 2. I never liked other Behr paints
Un popular opinion here, but I prefer behr ultra or marquee for interior due to ease of workability. Plus I don’t have to deal with SW supply and tint issues
Behr technically covers the best because the CPVC ratio (critical pigment volume concentration) is higher. More pigment = better coverage but also equals less binders,hardeners/fillers.
Honestly these videos are horrible.. For one thing, it's always better to run two coats of any paint. 2. It's not about just coverage, Yes, I prefer thin paint then thck paint.. if thin, paint can cover more than a thick one... im all ins.. as long as it's not runny.
Sorry, I was learning how to make videos then, I have tried really hard to make the newer videos better, I think if you check them out you will see an improvement... At least I hope so
