Hempcrete is a natural building material made from the inner core of the hemp plant, known as the hurd. It is mixed with a lime-based binder to create a lightweight, breathable, and insulating material that can be used for walls, floors, and roofs. Hempcrete is becoming increasingly popular in the construction industry due to its sustainability, durability, and energy efficiency.
In this video, Will Brain of BrainBuilt.com.au demonstrates the process of spraying hempcrete. This method is great for creating curves and infilling hard to hand-place spots, such as where the wall meets the ceiling or spots you might have missed during hand placing. The process begins with mixing the hemp hurd and lime-based binder together, then adding water to create a slurry. The slurry is then poured into a hopper and sprayed onto the surface using a specialized sprayer.
Spraying hempcrete is a great way to quickly and efficiently apply the material to walls, floors, and roofs. It is also much easier than hand-placing hempcrete, as it requires less labor and time. Additionally, spraying hempcrete allows for more precise application of the material, which can help reduce waste and improve energy efficiency.
Overall, spraying hempcrete is an effective and efficient way to apply this sustainable building material. It is a great option for those looking to save time and money while still achieving a high-quality finish. With its sustainability, durability, and energy efficiency, hempcrete is quickly becoming one of the most popular building materials in the construction industry.
