THANKS Clarence, I have a Lowes down the road and will check to see what they have.
While looking for the "green" sponge I came across THIS article. It looks very similar to what I have. The biggest surprise is that they didn't use a trowel or grout float. They used a 7" brush
It's called "SAND SWIRL" and they use something called Perlite. I haven't read the whole article but it seems very similar from what I've read so far.
Has anyone here ever used this Perlite? Could I just mix some sand with the paint to get a similar appearance? If so, then what kind of sand would be best to use?
