I've been using SW paints for many years. I trust the product to perform, and the manager always is willing to advise me on correct products, etc.
I used Duration Home satin today and I have to ask why is this product the "top of the line"? I find it very "watery" to apply. Once on the wall, it looks great. What makes it so durable? I primed with a gray primer #5.
I assumed a thicker paint (Promar 200 and Superpaint) would be the choice. The owner(a commercial job) selected the paint after talking with the SW rep.
The first time I used Duration Home, I thought it was a little thinner than other paints too. I'm used to it now and have no problem applying it. We have been using it for a couple of years on about 95% of our residential re-paints. I usually use the matte sheen and then either the satin or semi-gloss on trim. It is pretty durable and stain resistant and does look good once it is applied. Being that it has mildicides and is scrubable you can use it in every room including the bathroom and kitchen.
