Finishing calculators

Finishing trades have the highest wastage rates on site, and the coverage figures printed on packaging assume ideal surfaces. These tools keep both factors visible instead of hiding them inside a rate.

• Plaster Calculator Calculate plaster or render volume for a wall, and the cement and sand it needs.
• Paint Calculator Work out how much paint a wall or room needs, allowing for coats, openings and the coverage rate on the tin.
• Tile Calculator Calculate how many tiles a floor or wall needs, including grout joints and a cutting allowance.
