Although the watering can is so inconspicuous in our lives, although it is small in size, it has great effects! For example, when using diatom mud for house decoration, the content and quality of diatom mud have a great impact on the function of diatom mud. At this time, we can use a watering can to identify the quality of diatom mud. Good or bad.
The main purpose of using a watering can to spray water is to test the respiration and moisture absorption and release properties of diatom wall materials. Diatom wall material display boards use different materials and have completely different effects.

When identifying true and false diatom mud, first hold a watering can, about a centimeter away from the diatom mud wall, and spray water directly onto the wall. If it is real diatom mud, you will find that the moisture on the wall is quickly absorbed, and there will be no water stains on the wall when touched with the palm of your hand.
High-quality diatom mud can be sprayed on the same point of the wall more than once, quickly absorbing water without any water stains, and the wall surface will not fall off, have no color, and will not crack. After the high-quality diatom wall has been sprayed with water many times in a row, it will quickly absorb the water. If you press it gently with your thumbnail, you will find that the wall has turned into mud, but the appearance will not change.
After being sprayed with water according to the above method, inferior diatom mud walls will not absorb water like latex paint, wall art paint, and liquid wallpaper, and the water will flow down the wall. After spraying low-quality diatom mud with water and pressing it with your thumbnail, the wall will still be as hard as a cement wall or latex paint wall.
The key points of this testing method are the short, flat and fast rules. Repeatedly spray mist water on the same place of the diatom wall material until it is saturated to test how much water it can absorb. At the same time, in the saturated state, it can quickly absorb a large amount of water smoothly and smoothly in a short period of time. It is discharged and released (spit out), and the surface of the wall material quickly appears in a dry state, which is a high-quality diatom wall material. During the test period, the water discharge and release (spitting out) process of the diatom wall material is short, the speed is stable and even, and it can be judged as high quality if it can quickly dry out. If it encounters mist-like moisture and immediately becomes saturated, does not adsorb, and shows a large number of water droplets flowing, it can be concluded that it is an inferior diatom wall material that does not have the basic functions of breathing and absorbing and releasing moisture.
If liquid mist water molecules are difficult to adsorb quickly, how can we effectively and quickly capture and adsorb moisture free in the air in gaseous form? For high-quality diatom wall materials, even if the sprayed mist moisture is in a saturated state, it can be quickly and completely absorbed by the diatom wall material itself, and can be smoothly discharged and released (spit out) in a short period of time, leaving it in a dry state. This is the true meaning of testing method.
After the wall is allowed to dry for an hour, use high-quality diatom mud
The wall will be restored to its original state without any water marks or slag on the surface. After spraying water, the color of the wall appears to spread. If you touch it with your hands, the color of the wall will discolor. This is a phenomenon of inferior diatom mud.
