Plastering Walls in Your Home – How Unitech SA Gets It Right Every Time
At Unitech SA, we know that plastering is more than just a finishing touch – it’s the foundation for beautiful, long-lasting walls. Whether you’re building a new home or renovating, the right cement mixture for plastering is essential. Using the correct plaster mix ratio ensures that your walls are smooth, strong, and ready for years of wear.
We’ve worked on countless homes, and we’ve learned that knowing how to plaster a wall with cement properly is just as important as choosing the right materials. That’s why we use only top-quality products and proven techniques to deliver a finish that not only looks good but also protects your home.

Why the Right Plaster Mix Matters
When it comes to cement plaster, the quality of the mix directly affects the durability and appearance of your walls. At Unitech SA, we focus on getting every detail right.
A good plaster mix provides:
- Durability – The walls stay solid and resist cracking over time.
- A flawless finish – Smooth, even surfaces that are easy to paint or decorate.
- Moisture resistance – Reduces the risk of damp, mold, and peeling paint.
- If the wrong mix is used, the plaster may become brittle, absorb too much moisture, or fail to bond to the wall. That’s why our team never takes shortcuts.
How We Mix Cement for Plastering
Knowing how to mix cement for plastering is a skill that comes from experience. At Unitech SA, we combine years of know-how with precise measuring and mixing.
Here’s our process:
-
Select high-quality cement – We choose cement that offers strong bonding and durability.
-
Use clean, well-graded sand – No clay, silt, or organic matter that could weaken the plaster.
-
Follow the correct plaster mix ratio – Typically 1 part cement to 4–5 parts sand, depending on the surface and application.
-
Measure water carefully – Enough for smooth application without making the mix runny or weak.
-
Mix thoroughly – We ensure every grain of sand is coated with cement for an even texture.
This careful approach means your walls will have a strong, even coat of cement plaster that lasts.
