Please don't confuse bluntness with rudeness, but you tried to cut a corner to save a buck, and now you're screwed. I'm at a total loss as to what to do short of removing the screw up and starting over with what you walked away from. Sorry.
I started a project using Behr Smooth Texture Paint. I ran out and researched that I could make a substitute homemade texture paint out of joint compound mixed into my paint.
I got plain latex paint & dry joint compound. Based on all the info I found, I should not have to mix all that much dry powder to get into a nice texture. Well I now at equal parts paint to drywall powder and altho it seems sort of thick when i roll it onto my walls it droops or still runs. Kind of like egg whites that won't stiffen up. It eventually drys hard as a rock but I did a "knock down" technique with the Behr & I simply can't get to that stage with this stuff. I have to keep re-rolling it as it dries just to keep some definition and to keep it from wheeping down the walls. Thank goodness I don't need to do this much longer but what the heck am I doing wrong?
