Polyurethane

[William Bannister]

Has anyone ever mixed 2 different types of polyethylene together?
Im doing a house and have 4 large rooms to refinish hardwood floors and up to this point have always used the highest quality materials on the hardwood floors. I have always wondered if it would be worth saving money to mix product.
I have gotten away with this game for ages mixing paints. I would buy 5 dollar a gallon oops paint at Menards or Home Depo then get 5 cans and throw em all together so I could paint an entire building or several apts one color.
Today I saw 2 gallons of clear poly on sale for only 20 bucks per and the brand I use is like 33 dollars a gallon. The thought to mix suddenly popped in my head. Mix 2 gallons of Cabot name brand with 2 gallons of the similar but different name brand all into a 5 gallon jug so its the same product going down on all 4 floors.
Which brings next question has anyone used the Cabot name brand for covering wood floors . I have been up to this point using Mini Wax name brand poly.
