In this episode we chat with Ben Kerslake of CarringtonLIME. Rich visited him at his premises in the Forest of Dean. We discuss Ben winning a Blue Peter competition, getting his neighbours to work on his house, and painting a room for 50p! On a more serious note, we talk about lime, hot lime, Naturally Hydraulic Lime, training, and innovation.
