Household expanding foam

Household

— mounting foam, intended mainly for simple work that does not require special precision. The most noticeable feature of household compositions is that they are blown through the straw that comes with the bottle (unlike professional foams, for which a gun is used — see the relevant paragraph for more details). However, the differences are not limited to this. So, household brands of foam can have a smaller volume (from 350 mL), and after application, such a foam is noticeably deformed, and in both directions — first it expands almost twice, then it dries out by about 5 – 7%. For simple tasks like sealing cracks or installing doors, this is not critical, but such tools are not suitable for precise work. In addition, ideally, it is desirable to use up a cylinder of household foam at a time — otherwise you will have to blow the tube from the dried residues of the composition, which requires a special gas.
