That's what they have in our county 4h barn it works great. I was going to suggest the same but someone beat me to it.KGW Farms said:I like lime. It still 'soaks up' like dirst but at the same time it gets hard like concrete and is easy to clean. When you clean it a little of the lime may come up and need a touch up every year or so but it is cheap! You can but a lot of lime for what you would pay to have it concreted.
