Cement renders are not limited to external applications; they can also be used for internal renders. Internal cement renders are commonly applied to interior walls and ceilings to provide a smooth and durable finish. Here is some information about cement renders for internal applications:

1. Material Composition:

Internal cement renders are typically made from cement, sand, and water. The ratio of these components can vary depending on the desired consistency and application requirements. Additional additives may improve workability, adhesion, and crack resistance.

2. Application Process:

The application process for internal cement renders involves several steps:

- Surface Preparation: The surface to be rendered should be clean and free from dust, grease, or loose particles. Any existing coatings or finishes should be removed or adequately prepared.

- Bonding Agent: A bonding agent or primer may be applied to enhance the adhesion between the render and the substrate. This is especially important when using the render to smooth or non-absorbent surfaces.

- Mixing and Application: The cement render mixture is prepared by combining the cement, sand, and water in the appropriate proportions. The mixture is then applied to the surface using a trowel or spray equipment. Multiple layers may be applied, allowing each layer to dry before applying the next.

- Finishing: Once the render has partially dried, it can be smoothed or textured using various tools or techniques, depending on the desired finish. This can include techniques such as sponge float, trowel finish, or textured patterns.


3. Benefits of Internal Cement Renders:

- Durability: Internal cement renders provide a durable, long-lasting finish that withstands everyday wear and tear.

- Versatility: They can be applied to various interior surfaces, including masonry, concrete, plasterboard, or existing renders.

- Aesthetic Appeal: Cement renders for internal applications can be finished in different textures and colors, allowing various design options. They can be left as a smooth finish or textured to create visual interest.

 - Can be used to reduce moisture ingress when used with water proof additives and paying attention to detailed preparation and application requirements.  

 - Waterproof cement renders can be used as part of a basement waterproofing system provided that either external or internal drainage is used to adequately alleviate ground water pressure and any necessary measures are taken to deal with any cracks and joints which might be subject to  movement.


4. Maintenance:

Proper maintenance of internal cement renders involves regular cleaning and inspection for any signs of damage or deterioration. Any cracks or defects should be repaired promptly to prevent further issues. Following the manufacturer's recommendations for cleaning products and techniques is essential to avoid damaging the render.

When considering internal cement renders, consulting with professionals experienced in rendering and plastering is advisable. They can assess the specific requirements of your project, recommend the appropriate materials and techniques, and ensure a successful application and finish.
