In the last few weeks we have been getting plastered on a regular basis. To make the cob walls of the Roman building more waterproof we have been adding several coats of traditional lime render. The first coat was a sloppy ‘harling’ coat applied by hurling it at the wall , first with a churn brush but later with a tyrolean gun.

On top of that goes a base coat of lime and sand render and then a fine smooth coat under Adrian’s watchful eye. Lime wash will then provide a bright white finish.
