- Ready to Mix with Water at site.
- Suitable of interior walls, exterior walls and ceiling plaster works
- Easy to shift to any floor
- Has to be stocked in waterproof area
- Total Plastering Cost Per Sqft Is Same As Conventional Method
- Achieve Faster Plastering Work
Product Variants

All Other Bricks and Blocks
Plastering Coats and Application Thickness
Recommended thickness for 1st coat is 8-12mm.
Recommended thickness for 2nd coat is 6-8mm, upto a maximum total thickness of 18mm
After final coat, minimum 3 to 5 days curing must be done
Coverage
15 sq.ft. per bag of 40kg, with a thickness of 12mm for a reasonably even substrate
Water Demand W/W
6 liters per bag of 40kg, to be adjusted as per specific requirement
Application Instructions
1. The substrate should be visually dry and clean
2. It should be free from dust, dirt particles, foreign particlers, oil, grease, dirt, loose plaster, loose particles and other such particles which may affect the bonding
3. The surface should be well cleaned before application, using tools such as a wire brush, mop, water jet, etc.
4. There should not be dampness, leakage, fungus, efflorescence, etc.
5. To create reinforcement and reduce chances of cracking, cover all concrete and block joints with a chicken mesh or fibre.
Mixing
1. Apply a thin layer of the mix to the substrate before plastering.
Normally an initial layer of cement and water is applied under Traditional method. Instead of cement and water layer, a thin layer of the same Ready-Mix Plaster can be applied to avoid purchasing, maintaining and monitoring cement separately
2. Take a clean bucket and fill it up with 6 liters of clean and good quality water.
3. Cut open the Ready-Mix Plaster bags carefully and take out the material in as much quantity as may be required for a plastering work of around 45 min to 60 min.
Avoid mixing large quantities at once as it may affect the plasticity of unused mix and reusing of already mixed plaster is not advisable
4. Slowly pour the Ready-mix powder into the bucket filled with water. A sturdy, good quality bucket is recommended as it will be used many times for mixing. And if an electric operated mixer is used instead of hand mixing, a good quality bucket is a must.
5. Do not pour the powder into the bucket before water. Pouring powder first and then adding water would create lumps.
6. Mix the composition nicely for 5 minutes. Hand mixing would be sufficient, however if you want a better homogenous mixing, you can go for an electric operated hand mortar mixer.
7. Check for presence of any lumps or uneven mixing and remix for another 2 minutes. This will provide a good lumpfree, consistent and homogenous plaster
Application & Curing
1. Decide the level of thickness required. Based on that, pick the mixture and throw it on to the surface forcibly and uniformly, using a good trowel.
2. After this level the plaster to obtain desired finishing, using appropriate tools. For recommended tools please refer the relevant section provided later in this document
3. In case a 2nd coat is required, the surface with 1st coat should be roughened for the 2nd coat to bind to.
Give enough time between 1st and 2nd coats depending on your specifications, requirements and practice.
Recommended thickness for 1st coat is 8-12mm; and recommended thickness for 2nd coat is 6-8mm, upto a maximum total thickness of 18mm
4. After completing both the coats, carry out proper levelling to get a good finish as required, using appropriate tools. Again, there are different tools available for different kinds of finishing preferred. You can refer to our ‘Recommended Tools’ section for more information Do not forget to clean all the tools thoroughly after use.
5. A 40kg bag of Ready-Mix plaster with 6 liters of water would approximately cover an area of 15 sq.ft. with a thickness of 12mm for a reasonably even substrate
6. After final coat, spray water 2 to 3 times a day for 3 to 5 days for curing. In case you are opting for Self-curing Ready-Mix Plaster curing can be reduced to 3 days.
