Renders are crucial for building elevation, whether interior or external. They prepare the wall substrate so that it may be suitably built out for a flat face that can be painted, textured, or even clad. As a result, selecting the appropriate render is critical.
What Exactly Is Cement Render?
Looking for a visually appealing and cost-effective exterior finish? Then cement-based rendering is the ideal option for you. Cement render, often known as dry bag render, is the most prevalent type of render. It is composed of three major components: lime, sand, and cement.
1. The lime – Assists the render in avoiding cracking as it dries and hardens.
2. Sand – For applying the undercoats, coarser sand is added to the concrete render, and finer sand is used when applying the top coats.
3. Cement – The color of the render is determined by the cement used in the mix.
The Benefits Of Cement Rendering
• Low cost: Its three basic components make it incredibly affordable and a perfect solution for individuals on a limited budget. As a result, you may apply it to your entire property for a low cost.
• Simple to apply: It may be applied to any masonry surface, however, it is most typically used for bricks. Depending on how you apply it, you may get a smooth or textured finish (i.e. bagging or trowelling). It can also be simply painted if you haven’t chosen to color the cement itself, and this may be done at any point after the render has cured (at least 28 days).
The Drawbacks Of Cement Rendering
- More prone to cracking: Because it is not waterproof, it will crack with time. It might also have efflorescence’s (staining from the salt coming out of the bricks).
- Requires expert assistance: It is beneficial to have a professional prepare the walls properly since the effectiveness of the final render is almost entirely dependent on how well those walls are prepared.
What Exactly Is Acrylic Render?
Looking for an appealing and long-lasting exterior finish? Then acrylic rendering Sydney is the greatest invention for you. Acrylic render, as the name indicates, is any sort of render that incorporates acrylic, a type of plastic, into the mix. A wet render is becoming more common, making it a favored option.
The Benefits Of Acrylic Rendering
• Excellent adherence to all surfaces: Unlike traditional render, which will not attach to any surface, it may be applied to painted masonry, uneven concrete brick, fiber cement, and plasterboard.
• Extremely flexible and strong: It maintains elasticity, allowing for absorption, shrinkage, and resistance to surface cracking. This is especially useful if you live in a location where the weather varies greatly.
• Simple to apply: Can be rolled, troweled, or even sprayed onto a surface without the need for mixing.
• Attractive and versatile, it may be used in a variety of ways: Can provide a variety of finishes, such as a smooth surface similar to concrete or an aesthetically textured finish.
• Extremely rapid drying: It cures in a matter of days rather than a month as typical render, saving you time. There’s also no need to apply a second layer of paint because it may be colored to match the color of your wall.
• Better for your home: Allows the material beneath to “breathe,” resulting in a drier and healthier environment. However, it is also water-resistant and will not succumb to bacteria or fungi.
Acrylic Rendering’s Drawbacks
- Acrylic render is often more expensive than cement renders for various reasons:
- Acyclic is sold in pre-mixed buckets that often include more ingredients than the cement render equivalent.
- Because acrylic is typically used as a top coat, it must be preceded by a base coat.
