Additionally, you may need to obtain any necessary licenses or permits for the hair salon within the beauty salon. **

To apply concrete on concrete, the existing surface must be clean, free of debris, and properly moistened. A bonding agent or primer should be applied to the existing concrete to ensure adhesion. The fresh concrete mix can then be poured or pumped onto the existing surface and spread evenly using a screed or trowel. It is important to properly cure the new concrete to prevent cracking and ensure a strong bond between the two layers. **

Yes, it is possible to pour new concrete over old concrete as long as the existing concrete is in good condition and properly prepared. The old concrete should be clean, free of any loose debris, and roughened to provide a good bonding surface for the new concrete. Additionally, a bonding agent may be used to ensure a strong bond between the old and new concrete. It is important to consult with a professional to assess the condition of the existing concrete and determine the best approach for pouring new concrete over it. **

Cutting a concrete ceiling afterwards is possible, but it can be a challenging and labor-intensive task. It requires specialized equipment such as a concrete saw and may generate a significant amount of dust and debris. It is important to ensure that the structure can support the modifications and that proper safety measures are in place before attempting to cut a concrete ceiling. Consulting with a professional contractor or engineer is recommended to ensure the job is done safely and effectively. **

To cut concrete with a pressure washer, you would need a specialized attachment called a rotary nozzle or turbo nozzle. These nozzles concentrate the water pressure into a small, powerful stream that can cut through concrete. It is important to wear protective gear such as goggles and gloves when using a pressure washer to cut concrete, as the process can create a lot of debris and splashback. Additionally, make sure to work in a well-ventilated area and follow all safety precautions outlined in the pressure washer's manual. **

For setting lawn edging stones, garden concrete would be the better option. Garden concrete is specifically designed for outdoor use and is more durable and weather-resistant than concrete screed. It also has better adhesion properties, making it more suitable for securing the edging stones in place. Additionally, garden concrete is often formulated to be more resistant to cracking and shifting, which is important for maintaining the integrity of the lawn edging. **

To cast figures in a concrete style from plaster, you will need to first create a mold of the figure using a flexible material like silicone. Once the mold is ready, mix plaster with water according to the manufacturer's instructions and pour it into the mold. Allow the plaster to set and cure completely before carefully removing the figure from the mold. To achieve a concrete look, you can paint the plaster figure with a mixture of gray paint and water, or use a concrete finish spray to give it a textured appearance. **
