What Is Ready Mix Plaster? Benefits, Applications and How to Use It

Ready Mix Plaster is a factory-prepared dry plastering material designed to simplify wall plastering applications. Instead of separately measuring cement, sand and other required materials at the construction site, a ready mix plaster provides a more consistent dry mixture that can be mixed with the recommended quantity of clean water before application.

ProCon RP1 Ready Mix Plaster is designed for wall plastering applications in residential and commercial construction, including brick masonry and AAC block masonry.

What Is Ready Mix Plaster?

Ready Mix Plaster, also known as premixed plaster or pre-mixed wall plaster, is a dry powder material prepared with controlled proportions of cementitious and other suitable components.

The material is supplied in bags and mixed with water at the site according to the manufacturer’s recommended mixing procedure.

The main purpose of ready mix plaster is to provide a convenient and consistent plastering material while reducing the need for individual measurement and mixing of conventional plastering ingredients at the construction site.

Where Is Ready Mix Plaster Used?

Ready Mix Plaster can be used for various wall plastering applications, depending on the product specification and substrate.

Common applications include:

  • Internal wall plastering
  • External wall plastering
  • Brick masonry
  • AAC block masonry
  • Residential construction
  • Commercial construction
  • Renovation and repair applications

Before application, the substrate should be properly prepared and free from loose particles, dust, oil and other contaminants.

Benefits of Ready Mix Plaster

1. Consistent Mix

Factory-controlled preparation helps provide a more consistent material compared with manually measuring individual dry ingredients at different stages of construction.

2. Faster Application

Ready mix plaster simplifies the preparation process because the dry material is supplied in a ready-to-mix form.

3. Easy Site Handling

The material can be transported and stored in bags and mixed with the recommended quantity of clean water when required.

4. Excellent Coverage

The actual coverage depends on application thickness, surface condition, substrate and material consumption. Contractors should calculate material requirements according to the actual site conditions and manufacturer’s technical recommendations.

5. Suitable for Different Masonry Surfaces

Ready mix plaster can be used for suitable brick masonry and AAC block applications when the substrate is properly prepared.

How to Mix Ready Mix Plaster

For ProCon RP1 Ready Mix Plaster, approximately 6.5–7.0 litres of clean water is recommended per 40 kg bag, subject to the product’s technical instructions.

Mixing Procedure

  1. Add approximately 6.5–7.0 litres of clean water to a clean mixing container.
  2. Slowly add one 40 kg bag of ProCon RP1 Ready Mix Plaster while continuously stirring.
  3. Mix thoroughly until a uniform, lump-free consistency is obtained.
  4. Allow the material to stand if required by the manufacturer’s technical instructions and remix before application.
  5. Apply the prepared plaster uniformly to the properly prepared surface.
  6. Finish the surface according to the required plastering finish.

Do not add more water than recommended, as excessive water can affect the performance and consistency of the plaster.

Ready Mix Plaster for AAC Blocks

AAC blocks have different surface characteristics from conventional brick masonry. Proper substrate preparation and the correct plastering procedure are therefore important.

Before plastering AAC block walls, remove loose particles and dust and follow the manufacturer’s recommended application procedure.

ProCon RP1 can be considered for AAC block masonry applications where the product specification and site conditions are suitable.

Ready Mix Plaster vs Traditional Plaster

Traditional plastering generally involves separately measuring and mixing materials such as cement and sand at the construction site. Ready Mix Plaster, on the other hand, is supplied as a pre-prepared dry mixture that requires the addition of water before application.

The choice between the two depends on factors such as project requirements, material availability, labour practices, application method and required consistency.

How Much Water Is Required for a 40 kg Bag?

ProCon RP1 Ready Mix Plaster requires approximately 6.5–7.0 litres of clean water per 40 kg bag, according to the recommended mixing procedure.

The final consistency should be suitable for the intended application. Site conditions and application requirements should always be considered, and the manufacturer’s technical instructions should be followed.
