If you’re looking to improve the appearance and durability of your exterior surfaces, creating an exterior cement screed is a great option. A cement screed is a thin layer of cement that can be used to level or resurface concrete, providing a smooth and polished finish. In this step-by-step guide, we’ll walk you through the process of creating an exterior cement screed.

Materials You’ll Need

  • Cement
  • Sand
  • Water
  • Measuring tools (bucket, scale)
  • Mixing tools (shovel, trowel)
  • Leveling tools (spirit level, straightedge)

Step 1: Prepare the Surface

The first step in creating an exterior cement screed is to prepare the surface. Start by cleaning the existing concrete thoroughly to remove any dirt, debris, or loose particles. Patch up any cracks or holes to ensure a smooth and even surface for the screed.

Step 2: Calculate the Amount of Materials

Before you start mixing the cement, calculate the amount of materials you’ll need. To do this, measure the dimensions of the area you want to cover and determine the desired thickness of the screed. Use these measurements to calculate the amount of cement and sand required. A common ratio is 1 part cement to 3 parts sand, but you can adjust it based on your project’s needs.

Step 3: Mix the Cement and Sand

Once you have the measurements, it’s time to mix the cement and sand. Start by combining the dry ingredients in a clean container or mixing tray. Gradually add water while stirring the mixture until you achieve a smooth and workable consistency. Be careful not to make it too watery or too dry.

Step 4: Apply the Cement Screed

With your cement screed mixture ready, it’s time to apply it to the prepared surface. Start by pouring the mixture onto the surface and spreading it evenly using a shovel or trowel. Use a straightedge or leveling tool to ensure an even and level surface. Work in smaller sections, smoothing and leveling each one before moving on to the next.

Step 5: Curing and Finishing

After applying the cement screed, allow it to cure for at least 24 hours. Cover the surface with a plastic sheet to prevent it from drying too quickly and cracking. Once the screed has cured, you can add any desired finishing touches, such as brushing or polishing, to achieve your desired look.

Creating an exterior cement screed can significantly enhance the appearance and durability of your outdoor surfaces. By following this step-by-step guide, you can successfully create a smooth and polished finish on your concrete. Just remember to prepare the surface, calculate the materials, mix the cement and sand, apply the screed, and finish it off. Now you’re ready to transform your exterior spaces with a stunning cement screed!
