Foam glue is waterproof Plugging the leak?

Foam glue , that is, polyurethane foam caulking agent, which is composed of polyurethane prepolymer and catalyst Caulking products made of foaming agents and other materials are mainly used on different building materials, For exampletalk about plastic steel doors and windows, aluminum alloy doors and windows, etc. The gap between the wall and the wall can be filled with foam glue, which has good bonding, sealing, heat insulation and sound absorption effects. So can foam glue block water leaks? Following is the authorLet’s learn about it together.

1. Can styrofoam seal water leaks

can plug water leaks, because styrofoam itself has a certain waterproof effect. Foam glue has a wide range of uses. It can be used in the gaps between doors, windows, etc. and walls. After filling, it not only has the effect of sealing and plugging, but also can fix and bond doors and windows, and at the same time play the role of heat preservation and sound insulation. .

2. What should you pay attention to when using foam glue to plug leaks

1, pay attention to cleaning the surface

Use styrofoam to Before filling the gaps in the wall, it is necessary to remove the floating ash and oil stains on the wall surface. These substances will affect the adhesion effect of the foam glue, and the oil stain will also affect the curing of the foam glue. At the same time, after cleaning the surface, you need to spray a little water on it to prevent the wall from absorbing the moisture in the foam glue due to dryness and affecting the effect.

2, pay attention to the filling operation

The foam glue needs to be filled from bottom to top or from left to right. Vertical gaps should be filled from bottom to top, and horizontal gaps should be filled from bottom to top. Fill on top. Because foam rubber has a certain degree of expansion, when gluing, the gap cannot be filled all at once. Only 50%of the gap needs to be filled, and then After the foam of the styrofoam expands, it will slowly fill the entire gap, which can avoid the waste of styrofoam. At the same time, the speed of glue application should be uniform to avoid uneven filling.
