Preparing the Surface for Acrylic Render Application
Before you start applying the acrylic render to the surface, it is critical to prepare the surface properly. This will ensure a better finish and longer-lasting results. The preparation process involves inspecting the surface, repairing any damage, cleaning the surface, and applying a primer.
Inspecting the Surface
The first step in preparing the surface is to inspect it thoroughly for any damage or issues. Look for any cracks, holes, or loose materials on the surface. These imperfections can affect the final result and reduce the adhesion of the acrylic render to the surface. Make sure that the surface is also structurally sound and stable. If you find significant structural issues, you may need to consult a professional to address them before proceeding with the acrylic render application.
You should also check for any water damage or dampness on the surface. If there are signs of moisture, it is necessary to eliminate the source of the moisture and wait until the surface is completely dry before moving on to the next steps.
Repairing Damage or Cracks
Once you have identified any damage or cracks in the surface, it is crucial to repair them before applying the acrylic render. For small cracks or holes, you can use a suitable patching compound or masonry repair product to fill the gaps. Follow the manufacturer’s instructions regarding the application and drying time.
For larger cracks or damage, you may need to use a more robust repair method such as applying a layer of reinforced repair mortar or using steel mesh to provide additional support. In some cases, you may need to remove and replace damaged sections of the surface or consult a professional for more advanced repair methods.
After the repairs are complete, make sure the repaired areas are smooth and flush with the rest of the surface. This will ensure a seamless and even finish when you apply the acrylic render.
Cleaning the Surface
Once you have addressed any damage or cracks in the surface, the next step is to clean it thoroughly. The surface should be free of any dust, dirt, grease, or other contaminants. These substances may interfere with the adhesion of the acrylic render, leading to an inconsistent finish or premature failure.
Use a brush or broom to remove any loose debris, followed by a high-pressure water cleaner to wash away dust and dirt. In some cases, you may need to use a mild detergent or degreaser to remove tenacious dirt or grease. Make sure to rinse the surface thoroughly after using any cleaning products, and wait until it is completely dry before proceeding to the next step.
Applying a Primer
Once the surface is clean and dry, it’s time to apply a primer. A good quality primer will promote better adhesion of the acrylic render to the surface and provide a more durable and long-lasting finish. It will also help to prevent moisture from penetrating the surface and reduce the risk of efflorescence, a white powdery substance that can form on surfaces when salts migrate to the surface and react with the atmosphere.
Choose a primer that is specifically designed for use with acrylic renders and follow the manufacturer’s instructions regarding application and drying time. Typically, you will need to apply the primer using a brush, roller, or spray gun, ensuring that you have full coverage and an even coat. Allow the primer to dry completely before you start applying the acrylic render.
Tools and Materials Needed for DIY Acrylic Render
When undertaking a DIY acrylic render project, it’s essential to have the correct tools and materials at hand. This ensures the project runs smoothly and results in a professional, high-quality finish. The following list elaborates on the necessary tools and materials you will need for this project.
Acrylic Render Mix
The most important component for any rendering job is the render mix itself, and in this case, an acrylic render mix is required. Acrylic render is a premixed compound that’s specifically designed for exterior applications. It consists of a blend of cement, sand, and acrylic resins, which gives it excellent flexibility, water resistance, and durability.
This premixed render is available in various colors and textures, allowing you to achieve your desired finish with ease. You will need to purchase enough render mix to cover the entire surface area you intend to apply it over, as well as a small amount of extra material to account for any wastage or touch-ups needed during the process.
Trowel and Hawk
A trowel and hawk are essential hand tools required for applying and spreading the render mix onto the walls.
- Hawk: A hawk is a flat metal plate with a handle attached to its underside, which is used to hold the render mix. It allows for easy transportation and application of the material onto the walls. Hawks come in various sizes, and selecting the appropriate size depends on the size of your project and personal preference.

Polystyrene Float
A polystyrene float, also known as a sponge float, is a rectangular tool with a spongy or foam surface used for creating a textured, even finish on acrylic renders. The soft foam material allows for gentle, controlled pressure on the render, helping to create the desired texture without damaging the surface. Some polystyrene floats also come with a plastic trowel edge for additional smoothing and shaping if needed.
Paint Roller and Tray (for Primer)
Before applying the acrylic render, it’s essential to prime the surface of the wall with a suitable primer. A paint roller and tray make primer application quick, easy, and even. Choose a roller with a medium nap for smooth surfaces or a longer nap for textured surfaces to ensure adequate coverage.
Plastic Sheeting (for Protection)
Rendering can be a messy job, and protecting surrounding areas is vital to prevent staining and damage. Use plastic sheeting to cover windows, doors, and any other surfaces that you do not want the render mix to come into contact with. The sheeting can be secured with tape or weighed down so it doesn’t move during the rendering process.
Cleaning Supplies
Finally, make sure you have cleaning supplies at hand to clean your tools and any spills or splatters that may occur during the rendering process. This could include:
- Buckets of water
- Soft brushes or sponges
- Cloth rags or old towels
