When sealing the balcony window, you must beat the styrofoam! Increase the dust-proof sealing effect.
It's okay, the foaming agent is just a filling, and the sealant is the key, and there will be no water after sealing.
This gap is not very large and can be sealed with a blowing agent. >>>More
Styrofoam can be beaten, but after beating, it is cut with a wallpaper knife and then sealed with cement mortar (other materials such as glass glue or plaster can also be used).
The quality of the sealant mainly depends on the price, a penny for the price, and a good price for ten points. Generally, more than 20 yuan for three or five years is no problem. Seven or eight yuan will be kept for a year at most, and even cracking, peeling, and falling off in the same year. Also, remember to buy from regular sources.
