Check the elasticity of the gypsum board. By tapping with a hand, a very solid sound is given to indicate that the gypsum board is durable and durable. For example, a sound that is very empty indicates that there is an empty drum in the board and the texture is not good. The weight of the gypsum board can also be measured by the weight of the handcuff.
