I just painted my 8' by 12' shed with exterior satin paint. I was wondering if i would be able to put some type of sealant on it to keep it from scratching the paint over time. I am kinda looking for something non slip. I just don't know what I would be able to put over a satin paint that wouldn't ruin the paint.
Don't know that Satin paint was your best option for a shed floor. I would have used a semi-transparent stain, or, if you wanted it painted, a porch and floor enamel that holds up better to foot traffic. Any kind of sealer you put on is gonna potentially make the floor slippery.
