Mix Quantities — Plaster Mortar (1:6)
Cement bags, sand and water for Plaster Mortar (1:6) from wet volume with yield factor.
A 12 mm coat at 1:6 covers a surprising area per bag — and runs out anyway, because walls undulate and corners double-dip. The 30% extras allowance baked into the default thickness practice is honest, not pessimistic; lower it only on machine-applied work.
Formula
Note: Planning estimate only — strength for structural decisions (formwork striking, post-tensioning, loading) must be verified by site-cured specimens or a calibrated maturity system per the project specification.

About Mix Quantities — Plaster Mortar (1:6)
Mix Quantities — Plaster Mortar (1:6) computes the governing relationship dry vol = wet × factor; split 1:6; cement at 1,440 kg/m³; water = w/c × cement live as you type. A 12 mm coat at 1:6 covers a surprising area per bag — and runs out anyway, because walls undulate and corners double-dip. The 30% extras allowance baked into the default thickness practice is honest, not pessimistic; lower it only on machine-applied work. Defaults are pre-filled with realistic values for this exact scenario, and the worked example substitutes your numbers step by step so the math is never a black box.
How to use Mix Quantities — Plaster Mortar (1:6)
- 1Enter your values — Wet (finished) volume, Dry volume factor, Water-cement ratio, Wastage (sensible defaults are pre-filled).
- 2Read the live results: Cement (50 kg bags), Sand, Water.
- 3Check the "with your numbers" line to see dry vol = wet × factor; split 1:6; cement at 1,440 kg/m³; water = w/c × cement substituted step by step.
- 4Adjust inputs until the scenario matches yours, then copy or share the result.
Why use Mix Quantities — Plaster Mortar (1:6)?
- ✓Instant, free and private — every calculation runs client-side in your browser; nothing is uploaded
- ✓Built on the stated formula dry vol = wet × factor; split 1:6; cement at 1,440 kg/m³; water = w/c × cement with authoritative sources cited on the page (IS 456:2000 — Plain and reinforced concrete code of practice; IS 10262 — Concrete mix proportioning guidelines)
- ✓A 12 mm coat at 1:6 covers a surprising area per bag — and runs out anyway, because walls undulate and corners double-dip.
- ✓SI ⇄ Imperial toggle converts your inputs in place, so you can work in the units your drawings use
Frequently asked questions
What formula does the mix quantities — plaster mortar (1:6) use?+
It evaluates dry vol = wet × factor; split 1:6; cement at 1,440 kg/m³; water = w/c × cement, exactly as published. Sources: IS 456:2000 — Plain and reinforced concrete code of practice; IS 10262 — Concrete mix proportioning guidelines. The substituted worked example on the page lets you verify every step against the textbook.
How should I read the result — and how far can I trust it?+
A 12 mm coat at 1:6 covers a surprising area per bag — and runs out anyway, because walls undulate and corners double-dip. Planning estimate only — strength for structural decisions (formwork striking, post-tensioning, loading) must be verified by site-cured specimens or a calibrated maturity system per the project specification.
When is this calculator the right tool for the job?+
Cement bags, sand and water for Plaster Mortar (1:6) from wet volume with yield factor. A free concrete curing, maturity & strength tool. The 30% extras allowance baked into the default thickness practice is honest, not pessimistic; lower it only on machine-applied work. For neighbouring scenarios, the related tools below cover the same engine with different presets.
Does it support both metric and imperial units?+
Yes — the SI ⇄ Imperial toggle converts the values already in the fields, preserving the physical quantity, so you can flip mid-calculation without re-entering anything.
