What do you guys put on the floor? I've had a few batches in now and my 2 year old cement is starting to look pretty spotted. I've put down another coat of acrylic sealant but I would like to be able to not worry so much about spilling a little wort on the floor during brew days. I didn't plan the area around brewing beer so I have a cement floor. It's had two layers of acrylic sealant but that isn't helping too much. I'm thinking of raising the area a little, adding a floor drain and then tiling but that seems like a lot of effort and I'm wondering if someone has found a better solution.
