PlastoPlus
One-coat gypsum plaster
Description
PlastoPlus is a one-coat gypsum plaster for internal walls and ceilings. One kilo covers one square foot at 13 mm: proved on our customers’ sites. Your wall in square feet is your plaster in kilos.
We make PlastoPlus at Panvel. Our own lab at the factory tests the production batches. The QR code on every bag opens the test certificate of that batch.
Where to use
- Brick and AAC block: plaster directly.
- Mivan and RCC: Gypbond Pro goes on first. Then plaster.
- One coat, 6 to 20 mm thick.
Features
- One kilo. One square foot. At 13 mm. Proved on our customers’ sites.
- 93%+ white. A whiter base needs less putty and gives paint a brighter colour.
- Sets in 15 minutes. Final set.
- 5.85 N/mm² bending strength. Over 11 times the IS 2547 minimum.
- One coat. 6 to 20 mm in a single coat.
- No water curing. No curing wait before the next trade.
- Does not burn. Gypsum is non-combustible.
- Lighter. Less load than sand-cement plaster.
- Low heat flow. Gypsum conducts little heat.
- QR on every bag. Scan it. Read the test certificate of your batch.

| Coverage | 1.00 sq ft per kg at 13 mm (20 sq ft per 20 kg bag) | Proved on customers’ sites | Customer sites |
| Whiteness | 93%+ | Every batch: above 93% | Factory lab |
| Final set | 15 min | IS 2547: 10 to 30 min | Factory lab |
| Initial set | 4 min | Our range: 2 to 4 min | Factory lab |
| Workability | 11 min | Time to work the mix, in our test. Our range: 8 to 16 min | Factory lab |
| Bending (transverse) strength | 5.85 N/mm² | IS 2547: not less than 0.49 N/mm² | Factory lab |
| Compressive strength | 15.08 N/mm² | Factory lab | |
| Fineness | less than 2% left on a 150 µm sieve | IS 2547: not more than 5% | Factory lab |
| Surface hardness | 3.4 mm ball indentation | IS 2547: 3.0 to 4.5 mm | Factory lab |
| Expansion on setting | 0.14% | IS 2547: not more than 0.2% | Factory lab |
| pH | 6.5 | Our range: 6 to 8 | Factory lab |
| Heat on setting | 50.7 °C | Peak temperature as it sets. Our range: 45 to 53 °C | Factory lab |
| Dry bulk density | 780 kg/m³ | Powder, as packed. Our range: 600 to 800 | Factory lab |
| Normal consistency | 43% | Water for a workable mix | Factory lab |
| Shelf life | 1 year | In the closed bag, in a dry store, off the floor | |
| Mix | 1 water : 1.25 plaster | ||
| Thickness | 6 to 20 mm in one coat | ||
| Working time | Use each mix before it sets | Working time in our test: 8 to 16 min. Initial stiffening: 2 to 4 min. General practice: mix only what you can apply in this time. Do not add water to a mix that has started to set. | |
| Drying time before paint | Typical: 3 days | General practice for gypsum plaster. The time depends on the thickness and the weather. The plaster must be dry before you prime and paint. | |
| Tools | Mixing tray, trowel, straightedge | General practice. Use clean tools and clean water. | |
| Cleaning | Wash the tools with water before the plaster sets | General practice. Set plaster on a tool or in the tray makes the next mix set faster. |
Tested in our own lab at the Panvel factory, on production batches. Setting time is from a test sample: site time depends on water, batch and weather. A line marked "typical" or "general practice" is common to gypsum plasters: it is not a test result of this product.
Coverage
| Thickness | sq ft per kg | sq ft per 20 kg bag | 20 kg bags for 1,000 sq ft |
|---|---|---|---|
| 10 mm | 1.30 | 26.0 | 39 |
| 13 mm | 1.00 | 20.0 | 50 |
| 15 mm | 0.87 | 17.3 | 58 |
| 20 mm | 0.65 | 13.0 | 77 |
20 sq ft from one 20 kg bag at 13 mm. Coverage at another thickness is scaled in proportion. Bags are whole bags.
Application
- Clean. The wall must have no dust and no oil.
- Prime. Mivan and RCC only: roll on one coat of Gypbond Pro. Let it dry for 24 hours. Plaster within 14 days of coating. Brick and AAC block need no bonding coat.
- Measure. 1 part water to 1.25 parts plaster.
- Mix. Mix until smooth.
- Apply. One coat, 6 to 20 mm thick.
- Finish. Level the surface. Then trowel it.
- No water curing. Do not water the plaster after it sets.
Limits
- For internal walls and ceilings.
- One coat is not more than 20 mm.
- On Mivan and RCC, do not plaster without Gypbond Pro.
Packaging
- One pack: 20 kg bag.
- A QR code on every bag opens the test certificate of that batch.
Storage and shelf life
- Store the bags closed, in a dry and covered place.
- Keep them off the floor and away from damp walls.
- General practice, from IS 4082 for bagged cement: stack not more than 10 bags high.
- Shelf life: 1 year, in the closed bag.
Health and safety
- Gypsum plaster is a fine powder. Do not breathe the dust: wear a dust mask when you open a bag and when you mix.
- Wear gloves and eye protection.
- If powder or wet plaster gets in the eyes, rinse them with clean water.
- Wet plaster becomes hot as it sets. Never let plaster set around a hand or another body part: it can burn.
- Wash your hands after work. Keep the bags away from children.
