Plastering is an important part of building construction because it provides a finished and even surface for walls and ceilings. The quality of plaster can influence the appearance, bonding, durability, and finishing of a surface.
Ready Mix Plaster is a factory-manufactured plaster solution that is prepared using controlled proportions of cement, graded sand, polymers, fibres, and other performance-enhancing additives. It is supplied as a pre-mixed dry formulation and requires the addition of water before application.
Precise Conchem manufactures SILICO PLAST Polymerised Ready Mix Plaster, designed for internal and external plastering applications on different masonry and concrete surfaces.
What Is Ready Mix Plaster?
Ready Mix Plaster is a factory-produced cement-based plaster that is supplied as a pre-blended dry material. Instead of separately measuring cement, sand and additives at the construction site, the required materials are processed and proportioned during manufacturing.
The prepared plaster is mixed with the recommended quantity of water before application.
Ready Mix Plaster can be used for applications such as:
- Internal wall plastering
- External wall plastering
- Ceiling plastering
- AAC block plastering
- Brick wall plastering
- Concrete block plastering
- RCC surface plastering
- Renovation and repair work
SILICO PLAST is formulated for application on red clay bricks, fly ash bricks, concrete blocks, AAC lightweight blocks and other lightweight blocks.
How Does Ready Mix Plaster Work?
Ready Mix Plaster is manufactured under controlled conditions using defined proportions of its ingredients. This helps maintain consistency in the material supplied for plastering work.
At the construction site, the dry plaster is mixed with the recommended amount of potable water to obtain the required consistency.
For SILICO PLAST, Precise Conchem recommends approximately 6 to 6.5 litres of water for one 40 kg bag. The mixed material should be allowed to rest for around two minutes to support activation of the additives and polymers before application.
What Is Used in Ready Mix Plaster?
The formulation of Ready Mix Plaster can vary depending on the product. SILICO PLAST uses a combination of cement, processed graded river sand, polymers, fibres and additives.
Its listed formulation includes:
- Ordinary Portland Cement 53 with pozzolanic materials
- Processed and graded river sand
- Polymers
- Fibres
- Performance-enhancing additives
The maximum aggregate size specified for SILICO PLAST is 3 mm, with a listed mixture proportion of 1:3.
Benefits of Ready Mix Plaster
Consistent Material Composition
Because Ready Mix Plaster is factory manufactured, the materials are proportioned according to a defined formulation. This can help provide consistency between batches.
Convenient Site Preparation
Ready Mix Plaster reduces the requirement to separately measure cement, sand and other components at the construction site.
Easier Material Handling
The pre-packed formulation makes material storage, handling and reconciliation more convenient.
Faster Plastering Process
Ready Mix Plaster can simplify preparation and help improve workflow during plastering activities.
Reduced Material Wastage
Controlled material proportions and packaged quantities can help reduce unnecessary material handling and wastage.
Suitable for Multiple Surfaces
Depending on the product, Ready Mix Plaster can be used on brickwork, concrete blocks, AAC blocks, RCC surfaces and ceilings.
Ready Mix Plaster for Internal Walls
Internal wall plastering requires a suitable surface preparation and plastering system to achieve an even finish.
SILICO PLAST can be applied as a 10–12 mm single layer for internal plastering, according to the manufacturer’s specifications.
It can be used on suitable masonry and concrete surfaces before subsequent finishing activities such as painting or tile installation.
Ready Mix Plaster for External Walls
External walls are exposed to changing environmental conditions, making appropriate plaster selection and surface preparation important.
SILICO PLAST is designed for external plastering applications and is specified for a total thickness of 20–25 mm in two layers.
The manufacturer’s application method specifies a first layer of approximately 12 mm followed by a second layer of 8–10 mm after the recommended curing period.
Ready Mix Plaster for AAC Blocks
AAC blocks have specific surface characteristics that require suitable plastering materials and application methods.
Ready Mix Plaster can be used for AAC block plastering when the product is designed for this application.
SILICO PLAST is specifically listed for use on AAC lightweight blocks, along with red clay bricks, fly ash bricks and concrete blocks.
Ready Mix Plaster for RCC Surfaces
RCC surfaces require proper preparation before plaster application to achieve suitable adhesion.
Before applying SILICO PLAST to an RCC surface, the manufacturer recommends cleaning the surface thoroughly to remove dust, dirt, grease and other materials that may affect adhesion. A suitable bonding coat and key coat are also recommended as part of the application process.
At junctions between concrete surfaces and masonry walls, plaster reinforcement mesh is recommended according to the manufacturer’s application method.
Ready Mix Plaster Application Process
Correct surface preparation and application are important for achieving the intended plaster performance.
Step 1: Prepare the Surface
Remove dust, dirt, grease, loose particles and other materials that could affect adhesion.
Step 2: Prepare the Substrate
For brick and block masonry, the surface should be properly saturated with fresh water and masonry joints should be appropriately filled and raked.
Step 3: Add Water
For SILICO PLAST, use approximately 6–6.5 litres of potable water for a 40 kg bag.
Step 4: Mix Thoroughly
Add the plaster gradually to the water and mix until a smooth, creamy, lump-free and cohesive consistency is obtained.
Step 5: Allow the Mix to Rest
Allow the mixture to rest for approximately two minutes before final mixing and application.
Step 6: Apply the Plaster
Apply the material according to the recommended thickness and application method for the selected surface.
Step 7: Follow Layer Requirements
For thicknesses above the recommended single-layer thickness, appropriate surface preparation and layering should be followed.
The manufacturer’s technical instructions should always be followed for actual site application.
