Plaster Mortar Equation
V_{wet} = A_{net} times t; quad V_{dry} = 1.33 times V_{wet} times (1 + text{Wastage})
Engineering Specifications & Method of Calculation
Calculate plastering material batching for internal smooth walls (12mm), external weatherproof coatings (20mm), or ceilings (6mm).
Plastering Thickness Guidelines
Internal brick walls require 12mm plaster with a 1:4 to 1:6 cement-sand ratio. Ceiling plaster is typically 6mm at 1:3 or 1:4. External walls require 20mm two-coat waterproof plaster.
Frequently Asked Questions
How much plaster does one bag of cement cover?
One 50kg bag of cement with 1:4 mix at 12mm thickness covers approximately 16 to 18 square meters (170-195 sq ft).
