Render bags

MEASURE FIRST

How to prepare your inputs

Measure net wall area. Obtain the product consumption for the actual thickness and number of coats from the supplier.

How this calculation works

Product mass = area × total consumption × (1 + allowance). Packs round up.

Assumptions & exclusions

Enter total consumption covering all required coats or thickness, not a single-coat rate. Product example values are illustrative. Does not choose adhesive, waterproofing systems, thickness or compliance. Use the exact datasheet and substrate requirements.

Your next step

Confirm substrate preparation, reinforcing, movement joints, finishing and curing with your renderer.

What if my shape or product is different?

Use dimensions and product data that match the stated method. For complex work, calculate separate sections or obtain a project-specific take-off. Do not apply simple geometry to structural or compliance decisions.

Why are quantities rounded up?

Whole bags, packs, sheets or cartridges round up to purchasable units. Decimal area or volume results are planning figures; confirm order increments with the supplier.
