Differences between dry trowelling and wet trowelling
Dry trowelling and wet trowelling are two different methods used in the process of finishing concrete surfaces. While both techniques are aimed at achieving a smooth and polished look, there are distinct differences between them.
Dry trowelling refers to the technique of using a power trowel without any water or other liquid. It involves running the power trowel over the surface of the concrete to smooth out any imperfections and create a polished finish. This method is typically used when the concrete has already cured and hardened.
Wet trowelling, on the other hand, involves the use of water or a liquid mixture to aid in the trowelling process. The liquid helps lubricate the surface and allows the trowel to glide smoothly across the concrete. Wet trowelling is often done while the concrete is still in the early stages of setting and has not fully hardened.
One of the main differences between dry trowelling and wet trowelling is the timing at which they are performed. Dry trowelling is done after the concrete has set and hardened, while wet trowelling is done while the concrete is still in the plastic state and can be easily manipulated.
Another difference lies in the finish achieved. Dry trowelling typically results in a harder and denser surface, as the absence of water or liquid allows the concrete to cure fully. Wet trowelling, on the other hand, can produce a smoother and more polished finish due to the addition of water or liquid.
Additionally, the equipment used for dry trowelling and wet trowelling may also differ. Dry trowelling often requires the use of a power trowel with blades specifically designed for dry applications. Wet trowelling may involve a power trowel with specially designed blades that can handle the presence of water or liquid.
In conclusion, while dry trowelling and wet trowelling have the common goal of achieving a smooth and polished concrete surface, they differ in terms of timing, finish, and equipment used. The choice between the two methods depends on factors such as the stage of concrete setting, desired finish, and specific requirements of the project.
