A typically daily rate for a plasterer varies from Â£150 - Â£250 depending on the materials required and the location in the country. A plasterer's hourly rate (plus material costs) will be about Â£26 per hour (as of August 31, 2017) depending on where you are in the country.
If a plasterer skimped on materials, the wall may not have sufficient plaster thickness to withstand the normal stresses within a building. The minimum total thickness for plaster on gypsum board (rock lath) is 1/2 inch. On metal lath the minimum thickness is 5/8 inch; and for wood lath it is about 3/4 to 7/8 inch.
