| Tim and Lee were excellent instructors showing how best to repair flint walls. Tim recommended a mix of three parts sharp sand to one part hydrated lime, with enough water added to make a pliable but not too wet mix. Tim guided attendees how best to apply the mix with a trowel. Tim waits for the lime to set sufficiently, then pushes the lime deep into the wall. Once set, the lime is brushed off and wiped. The repaired wall will then be left slowly to dry……Hessian covering helps prevent the lime setting too quickly in sunny ocations. Volunteers discovered it is not as easy as Tim makes it appear – but of course he has decades of experience! Thanks to Tim, Lee, Howard and Paul for their cooperation. |
