Preparing Acrylic Renders for Mixing

The first step in using acrylic renders correctly is preparing them for mixing. It’s important to make sure all materials used are clean and dry before getting started. The materials should be dampened if needed, but not wet. Once these preliminary steps have been taken, the acrylic render can be measured and mixed.

For best results, mix the acrylic render in a clean bucket with a drill-mounted mixer. This will ensure that all of the materials are evenly combined. The water content should also be right to ensure that the mixture is not too thin or thick. If it’s too thin, it won’t adhere properly; if it’s too thick, it could crack and peeling will occur when dry.


Applying Acrylic Renders

Once you have prepared your acrylic render for mixing, you can then begin applying it to your exterior wall surface. It is important to make sure that the surface is even and free from dust before starting this process. Any uneven surfaces should be sanded down and the dust removed.

Once the surface is ready, you can begin applying the acrylic render with a trowel or sprayer. If using a trowel, make sure to spread it evenly across the entire wall surface. Smooth any ridges as you go along with your hand. When using a sprayer, be sure to move steadily in one direction so that all areas are adequately covered.


Protecting Acrylic Renders

The last step in ensuring that your acrylic renders last long-term is protecting them from weather damage. This can be done by applying an acrylic sealant or waterproof coating once the application of render has been completed and given time to dry.

These sealants and coatings should be applied using a paint roller or brush. It is important to make sure that the entire surface is covered evenly with the sealant or coating. Once this application has been completed, wait for it to dry before applying a second coat if needed.


In conclusion, mixing, applying and protecting acrylic renders correctly is essential to ensure long-term durability and aesthetic appeal. Make sure all materials are clean and dry before beginning, mix in a clean bucket with a drill-mounted mixer, apply the render evenly and smoothly with either a trowel or sprayer, and finally protect the render from weather damage by adding an acrylic sealant or waterproof coating. With these steps taken care of, you can be confident that your exterior walls will look great for years to come!
