How to Moisture proof Piano

Updated: Dec 24, 2019

I am a professional piano tuner. I often encounter a question from customers: How can the piano moistureproof effect be the best?


Most people buy moistureproof pipes when they buy piano, which proves that most people still attach great importance to the moistureproof work of piano. But how to moistureproof the most scientific, convenient, the best effect? Below are some of my personal views, here for your reference.


Nowadays, many families are equipped with air conditioning. Everyone knows that air conditioning has a dehumidification function, but I personally think that using the dehumidification function of air conditioning to damp the piano is not a good way. Firstly, from the economic point of view, the power consumption of air-conditioning is much larger than that of damp-proof tube; from the effect point of view, air-conditioning is to dehumidify the whole space, because the piano is a relatively sealed space, if the piano has invaded the moisture, the moisture will be closed inside, and the effect of space-time adjustment on its dehumidification is very small. Slow.


The function of dehumidifier and air conditioning have little difference, and most households in Guangdong do not have dehumidifier because of living habits and price problems of dehumidifier. Therefore, I think the most practical and convenient method of piano moistureproof is the combination of moistureproof tube and dehumidification box.

When we are aware of the need for moisture-proof maintenance of the piano, it is often wet for many days or after several days of rain, this time the air humidity has been considerable, moisture has entered the piano interior. What we usually call moistureproof, in fact, is called tide drive. Then, it is the best choice to use self-heating and damp-proof tube placed inside the piano.


Usually we use damp-proof pipes are used to fix damp-proof pipes under the door, but where is the most appropriate place for damp-proof pipes?


We need to find the answer to this question from a physical point of view. It is well known that the air rises when heated, so when the damp pipe is heated at the lower door, the air will gather at the top of the piano. Because the top of the piano is closed, the humid gas will stay at the top of the piano for a period of time before it evaporates slowly.


Because the position of the piano stringer is on the top of the piano, the timber, felt and felt used in the stringer are all damp objects, which may be damaged during the stay time of the moisture. Therefore, if we put the damp-proof pipe at the door of the piano, let the heat spread around, directly protect the stringer from moisture invasion, and put one or two damp-absorbing boxes at the bottom of the piano, the effect of damp-driving will be more ideal.

A hand-rolled piano is a foldable piano keyboard called a "Hand Roll Piano". Since it can be rolled up and folded, it is convenient to carry around.
