How to Use Thinset Mortar Resurface Concrete

1. Make sure the concrete is clean and free of debris. This may include removing any paint, sealant, or other coatings from the surface. Clean the concrete with a detergent solution and a scrub brush. Rinse the concrete thoroughly with clean water and allow it to dry completely.

2. Apply a layer of thinset mortar to the concrete. Use a trowel or float to apply the thinset evenly to the surface. The thickness of the layer should be about 1/4 inch.

3. Let the thinset mortar set for the recommended time. This may vary depending on the type of thinset mortar used, so check the manufacturer's instructions.

4. Apply a second layer of thinset mortar. This layer should be applied in a perpendicular direction to the first layer. The thickness of this layer should also be about 1/4 inch.

5. Allow the thinset mortar to cure completely. This may take several days or weeks, again depending on the type of thinset mortar used. Check the manufacturer's instructions for specific curing times.

6. Once the thinset mortar has cured, you can apply a sealer or paint to the concrete to protect it. This will help to prevent wear and tear and make the concrete easier to clean.

Tips for Resurfacing Concrete with Thinset Mortar:

- Use a high-quality thinset mortar that is specifically designed for resurfacing concrete.

- Apply the thinset mortar in a thin, even layer.

- Allow the thinset mortar to set and cure completely before applying any sealer or paint.

- If you are resurfacing a large area of concrete, it may be helpful to use a power sander or diamond grinder to prepare the surface before applying the thinset mortar.

By following these tips, you can successfully resurface concrete with thinset mortar and create a new, durable, and attractive surface.
