Edited for some grammatic as well as punctuation mistakes. Likewise added a declaration concerning seasonal useage of various items.
I'll allow you in one a key: the cost professionals pay for most of the paint at Sherwin-Williams or Benjamin Moore costs them much less than what you pay for a gallon of Behr.
Basically, Sherwin-Williams as well as various other paint manufacturers/sellers act as both wholesalers and merchants at the very same time.
To cover it off, the state-of-the-art paint at Lowe's, House Depot, or any type of various other house facility is most likely about the exact same item as the top-line builder/painter grade product.
SW and also BenMoore's top paints are chemically better than those items. Seriously. They use greater quality components as well as chemistry that is merely advanced.
Currently, if you like one over the other, simply utilize it. Yes some are much more scrubable, cleanable, mar immune, have better splatter control, etc, yet most painters don't buy exclusively from one location.
In fact, one repair professional I recognize makes use of products from all over the place. He has carefully evaluated guides, leading coats, varishes, spots, caulks, and so on. And also in as many different ways as feasible. He will certainly make use of one brand for a latex guide, a various one for oil, and a 3rd brand name for smoke/stain blocking. And then he will switch as required between 'summer' products and 'wintertime' products.
However, I think you may desire some fast solutions:
General Customer service
Ability to make an easy call and also make an order
Quantity of item available (I would keep 200-- 500 gallons of some products handy for some products. You will not discover that a lot in your home Depot at once, total).
Educated store personnel
Uniformity in shade criteria
Uniformity of staff
Full-service chances (acquire high-end sprayers and various other equipment).
Quality of product.
Efficiency (125 feet from truck to counter versus 125 feet from vehicle to ... still in the car park).
Donuts and bagels (I would certainly purchase these every Friday).
I could possibly locate extra, however I assume I've made some good points.
