OM Group manufactures and supplies Plaster Sand — also known commercially as P-Sand — across North and South Goa, for internal, external and ceiling plastering.
OM Group manufactures Plaster Sand, also supplied commercially as P-Sand, for internal, external and ceiling plastering across North and South Goa. Plastering requires a different sand grading than structural concrete work, and Plaster Sand is produced and classified against IS 1542:1992, the Indian Standard specific to sand for plaster.
OM Group manufactures and supplies it under the commercial name P-Sand, alongside its Plaster Sand designation.
IS 1542:1992 recognises natural sand, crushed stone sand and crushed gravel sand as eligible sources, provided the material meets the standard's grading and cleanliness requirements — meaning plaster sand is properly understood as a grading and cleanliness specification, not a single fixed raw material.
Plastering is a thin, trowel-applied layer, and the sand's particle-size distribution has a direct effect on finish, workability and cracking risk in a way that matters less in a thick structural pour.
IS 1542:1992 requires sand for plaster to be hard, durable and clean, with combined clay, silt, dust and organic impurities not exceeding 5% by mass. Grading is established by sieve analysis under IS 2386 (Part 1), with a minimum fineness modulus of 1.4 for crushed stone or crushed gravel sand and 1.5 for natural sand. The limit on material passing the 150-micron sieve is relaxed to 20% specifically for crushed sources, since crushed rock fines behave differently from the clay-bearing fines typical of natural sand.
A controlled amount of fine material is expected, not eliminated. IS 1542 sets a minimum fineness modulus and a maximum fines limit — it does not require zero fines. Concrete-grade M-Sand is not automatically the same as plaster-grade sand; the two are classified against different targets.
Current grading information for the material OM Group supplies is available on request.
Plaster Sand and M-Sand belong to the same broad material family — crushed stone fine aggregate — classified against two different targets: IS 383's Zone II for structural concrete, and IS 1542's finer, differently-fined envelope for plastering. OM Group manufactures both, produced and graded for their respective applications.
Using concrete-grade material as-is for plastering can produce a rougher finish and higher rebound loss, since it isn't classified to the specification plastering requires. For full technical detail on M-Sand and IS 383 grading, see M-Sand.
"Washed" describes a processing stage; "plaster-grade" describes a grading specification. Washed material may or may not meet IS 1542's grading requirements on its own — washing affects cleanliness and fines content, not particle-size distribution by itself. Washed Sand and Plaster Sand can therefore overlap in a given batch of material without being interchangeable terms. See Washed Sand for detail on OM Group's washing specification.
Plaster Sand is selected for plastering and mortar requirements, while concrete sand is selected for concrete mix requirements. The two should not be treated as interchangeable simply because both are fine aggregates.
| Attribute | Plaster Sand | Concrete Sand |
|---|---|---|
| Primary application | Wall and ceiling plastering, mortar | Concrete mix |
| Specification context | IS 1542:1992 | Concrete-grade fine aggregate, generally IS 383:2016 |
| Grading objective | Fine, plaster-suited distribution | Suited to the concrete mix design |
| Workability | Trowel workability for a thin applied layer | Workability within a structural concrete mix |
| Finish | Smooth, trowel-finished surface | Not applicable as a finished surface |
| Selection basis | Project plaster specification | Approved concrete mix design |
| Plaster Sand | River / Natural Sand | |
|---|---|---|
| Source | Crushed rock, classified to IS 1542 | Naturally deposited |
| Fineness modulus (IS 1542 minimum) | 1.4 | 1.5 |
| Fines character | Rock flour, non-plastic | Often clay-bearing |
| Grading control | Process-controlled, consistent where classification is controlled | Varies by deposit and lot |
| Availability in Goa | Manufactured to demand | Subject to current regulatory conditions on extraction |
Neither is universally superior — IS 1542 accepts both, subject to meeting its grading and cleanliness limits.
Stone dust and quarry dust are the uncontrolled fine by-product of crushing, not classified to any grading standard, and not a substitute for Plaster Sand under any circumstance. Substituting dust for graded plaster sand produces unpredictable water demand, poor workability, and a compromised, often cracked finish — a costlier failure to redo than most structural grading errors, since it's visible on the finished wall.
Particle-size distribution against IS 1542, confirmed by sieve analysis.
Controlled, not absent; excessive fines risk shrinkage cracking, insufficient fines hurt workability.
Free of organic matter and deleterious material.
Reliable grading batch to batch, produced under OM Group's own processing and quality control.
Finish quality also depends on mix ratio, water content, application thickness, substrate and workmanship — sand grading is one factor among several.

OM Group manufactures Plaster Sand through its own processing and grading operations, classifying material against IS 1542's requirements for plastering use, rather than reselling generic sand sourced from elsewhere.
Source material is processed through screening and grading to separate and classify the fine fraction appropriate for plaster use. Quality checks confirm the material against the applicable grading before dispatch. Material is stockpiled and dispatched on OM Group's own transport fleet, with operational bases at Kundaim and Thivim in North Goa and Sancoale in South Goa, for delivery across North and South Goa.
Current grading and specification information for the material being supplied is available on request.

OM Group's Plaster Sand is produced for plastering requirements, with IS 1542:1992 serving as the relevant Indian specification; current grading and documentation can be confirmed against the project requirement.
IS 1542:1992 is the Indian Standard specifying requirements for sand used in plaster mortar, covering natural, crushed stone and crushed gravel sand sources.
IS 1542:1992 sets grading limits via sieve analysis, a minimum fineness modulus of 1.4 for crushed sources and 1.5 for natural sand, and a combined fines limit of 5%.
Fineness modulus is a numerical index of a sand's average particle size, derived from sieve analysis, used to assess grading suitability.
OM Group does not publish a fixed fineness-modulus value as a permanent product property; current test data can be confirmed against the material being supplied.
IS 1542 permits combined clay, silt, dust and organic impurities up to 5% by mass — a controlled amount, not zero.
Yes — a controlled proportion of fines is normal and expected under IS 1542, contributing to workability.
Concrete-grade M-Sand is generally coarser than material classified to IS 1542. Plaster-specific grading is what plastering specifications generally call for.
Both are manufactured from crushed stone; Plaster Sand is classified to IS 1542 for plastering, while M-Sand is typically classified to IS 383 Zone II for concrete.
Washing describes a processing stage affecting cleanliness and fines; Plaster Sand describes a grading specification for plastering. The two can overlap without being interchangeable terms.
Plaster Sand is selected for plastering and mortar requirements; concrete sand is selected for concrete mix requirements. Both are fine aggregates, but they are not interchangeable.
River sand is naturally deposited; Plaster Sand is manufactured and classified to IS 1542. Both are eligible sources under the standard provided grading and cleanliness requirements are met.
Stone dust is the uncontrolled fine by-product of crushing, not classified to any grading standard. Plaster Sand is classified to IS 1542 and is not interchangeable with dust.
