Service life of foam sealant

No, the main component of styrofoam is usually polyurethane, which is generally unstable. After spraying, it reacts with moisture in the air to solidify and set. After the reaction is completed, it is difficult to clean up, not to mention failure, even if it is stuck on something, it is difficult for you to clean up. Except the special styrofoam cleaning agent, the removal effect of other things is not good, so don't worry about the failure of styrofoam.

However, after installing the wooden door, there are other situations that can cause problems with styrofoam:

1. In order to save costs, the installer or manufacturer reduced the amount of styrofoam used on each door cover. In theory, all the positions are filled, and the most perfect effect is not to see the gap. Take a step back, hit five points up and down, and hit three points at the top, which can also ensure the strength. If it is less, the effect is hard to say.

2. In order to be quick, the installer began to install the door leaf when the styrofoam was not completely dry, deformed or not firmly bonded.

3, the manufacturer's door cover material itself is not strong enough, this is easy to understand, the thing itself has defects, and even the best glue can't stick.

4. There is something wrong with the wall of your cave, such as the wall cracking and falling off due to moisture.

The styrofoam provided by the manufacturer is inferior. After spraying from the tank, the reaction speed is extremely slow, and the foaming effect is poor, which affects the adhesion.

If the above five items can be ruled out, it is almost impossible for styrofoam to go wrong.
