Wall Coating Calculator
How much coating do you need?
Add each wall with its length and height, then add every door and window on that wall individually — sizes can all differ. Choose your finish and we'll estimate how many 25kg buckets to order.
Include Undercoat (levelling coat)
Recommended base layer before Gamazine or Granite — covers 15 m² per 25kg.

How To Measure Your Walls
Follow these simple steps to get accurate dimensions for a flawless architectural finish.
01
Measure Overall Dimensions
Multiply the total height by the total width of the wall surface to get the gross square meterage.
02
Identify Openings
Measure the height and width of any doors, windows, or fixed cabinetry that will not be coated.
