Lath and Plasterwork

Lath and plasterwork continues at Wingfield Station - this is a very time consuming process!

Laths have been fixed across the underside of joists or horizontally on stud work and have to be lightly dampened immediately prior to the application of the first coat of plaster (the 'pricking up' coat) to remove any dust.

Once the plaster has been applied a cross hatch key must be formed in the surface with a wooden scratch comb in order to create a mechanical key for the second coat (the 'floating coat').

The plasterers are using non hydraulic lime putty that has matured for a minimum of 3 months.

Drying out take a long time - rapid drying has to be avoided as this leads to poor carbonation of the lime and, ultimately, failure!
