Brick masonry is one of the most common wall construction methods used in residential, commercial and other building projects. Proper plastering helps create a smooth, uniform surface and prepares the wall for finishing treatments such as painting.
Traditionally, brick walls are plastered using a cement and sand mixture prepared at the construction site. However, Ready Mix Plaster for brick walls provides an alternative in which the dry plastering material is pre-prepared and supplied in bags, requiring the recommended quantity of water to be added before application.
In this guide, we explain what ready mix plaster is, how it can be used on brick masonry, how to prepare the surface and the recommended steps for applying plaster to brick walls.
What Is Ready Mix Plaster for Brick Walls?
Ready Mix Plaster is a factory-prepared dry plastering material designed for suitable masonry applications. Instead of separately measuring cement and sand at the construction site, the plaster is supplied as a prepared dry formulation.
When required, the material is mixed with the manufacturer’s recommended quantity of clean water and then applied to the prepared wall surface.
ProCon RP1 Ready Mix Plaster is a polymer-modified plaster supplied in a 40 kg bag and is intended for suitable internal and external wall plastering applications, including brick masonry.
Can Ready Mix Plaster Be Used on Brick Walls?
Yes, a ready mix plaster product specified for brick masonry can be used for plastering brick walls.
However, successful plastering depends on more than the plaster material itself. The brick surface must be properly prepared, the material must be mixed according to the manufacturer’s instructions, and the plaster must be applied at the appropriate thickness and under suitable site conditions.
Before beginning the application, always check the product’s technical specifications and recommended application procedure.
Why Use Ready Mix Plaster for Brick Masonry?
Ready mix plaster can provide several practical advantages when used for suitable brick wall applications.
1. Pre-Prepared Dry Formulation
The dry material is prepared before it reaches the construction site. This reduces the need to separately measure multiple dry ingredients for every batch.
2. Consistent Material Preparation
A factory-controlled formulation can help provide greater consistency between batches when the recommended mixing procedure is followed correctly.
3. Convenient Site Handling
The material is supplied in bags, making transportation, storage and handling more convenient compared with separately handling loose sand and cement.
4. Simplified Mixing
Ready mix plaster only requires the recommended quantity of clean water to be added before application, simplifying the material preparation process.
5. Suitable for Residential and Commercial Projects
Ready mix plaster can be considered for suitable brick masonry applications in residential buildings, commercial buildings and other construction projects.
Preparing a Brick Wall Before Plastering
Proper surface preparation is an important part of achieving a good plastering result.
Before applying ready mix plaster, inspect the brick wall and remove loose material, dust, dirt, oil, laitance or other contaminants that could affect adhesion.
The wall should be stable and suitable for plastering. Any damaged or loose sections should be repaired before the plastering work begins.
Depending on the brickwork and site conditions, the surface may require appropriate dampening or other preparation according to the plaster manufacturer’s recommendations.
Do not begin plastering over a surface that is excessively dusty, contaminated or otherwise unsuitable.

Prepare ProCon RP1 Ready Mix Plaster using approximately 6.5–7.0 litres of clean water per 40 kg bag, according to the product’s technical instructions.
Step 4: Apply the Plaster
Apply the prepared plaster uniformly over the prepared brick surface using suitable plastering tools.
Step 5: Level the Surface
Spread and level the plaster to achieve the required surface profile and thickness.
Step 6: Finish the Surface
Finish the surface according to the desired project requirement and the manufacturer’s recommendations.
Step 7: Follow Curing and Aftercare Requirements
Follow the manufacturer’s recommended curing and aftercare procedure. Proper curing and protection from unsuitable environmental conditions can be important for cement-based plastering systems.
Internal Brick Wall Plastering
Ready mix plaster can be used for suitable internal brick wall applications.
For internal walls, the surface should be properly prepared before application. The required plaster thickness, finishing method and subsequent painting or finishing work should be determined according to the project requirements.
A properly prepared and finished plaster surface can provide a suitable base for subsequent decorative finishes.
External Brick Wall Plastering
External walls are exposed to weather and environmental conditions, so the plastering material and application procedure should be suitable for external use.
When using ready mix plaster for external brick walls, make sure the product is specified for external applications and follow the manufacturer’s recommendations for surface preparation, application, finishing and curing.
Ready Mix Plaster vs Traditional Cement Plaster for Brick Walls
Traditional cement plaster generally requires cement and sand to be separately measured and mixed at the construction site.
Ready mix plaster is supplied as a pre-prepared dry formulation and requires the recommended quantity of water before application.
For brick wall construction, the choice between the two can depend on project requirements, material availability, labour practices, site conditions and preferred construction methods.
Ready mix plaster can be particularly convenient when simplified material preparation, bagged handling and a controlled dry formulation are important.
Common Mistakes to Avoid When Plastering Brick Walls
