How to eliminate the mounting foam from the door surface before it is still dry?

If you, by blowing out doors or anything else with a similar sealant, notice that she accidentally got to where she does not need to be, she needs to be eliminated as soon as possible.

Important! Under no circumstances should you try to do this with water.

You may be surprised that the more and longer this type of sealant comes into contact with water, the faster it dries.

Remove with ordinary acetone as soon as possible. It dissolves the liquid sealant right in front of your eyes. This is because hard bonds between molecules have not yet formed in it. But acetone cannot dissolve a dried mixture. The hardened mass is firmly connected at the molecular level and a rigid framework is formed. Therefore, if you missed the moment, wipe the mounting foam from the metal door, other tools will help you.

How to clean the mounting foam from the door if it has already frozen?

After the sealant has dried and then fully polymerized, you only need to use the mechanical method of removal. But in such a situation, do not panic. In most cases, the mortar for repairing cracks and joints is removed quite well. Although of course, a lot depends on the surface on which it appeared.

If the doors are metal, and at the same time they are not painted, then there will be no trace of building sealant, but if the foam got on the surface of wooden doors, then get ready to tinker with it.

How to clean polyurethane foam?

If you had to face a situation where the sealant has already solidified, but not where you needed it, use one of the following means. All of them are tested in practice by home craftsmen and professional masters of finishing and construction works, so for sure you will be able to remove the mounting foam.

Special tools

The easiest and surest way is to use special chemicals to wipe the mounting foam from the metal door. The removal speed will be high, as well as the quality of the result, but you should be prepared to ensure that, along with the foam, a paint layer may come off.

Important! It is advisable to purchase a wash from the same manufacturer as the sealant itself. So the likelihood of a coincidence of the chemical composition of mutually applicable agents is much higher.

Delicate method

In the event that you abandoned the use of chemistry and decided to eliminate the sealant from the door surface with your own hands, you must arm yourself with a knife or a scraper, a kitchen sponge, on one side of which there is a rough surface.

Use gentle mechanical movements to scrape the dried mortar from your door. If, after the cleaning is completed, small traces or scratches remain, they can be hidden with a polish.

Dimexide

When the polymerized solution lends itself rather poorly, you can try to dissolve its dimethyl sulfoxide. You can get it in a pharmacy - this medicine is called "Dimexidum".

Important! "Dimexide" is incredibly well absorbed into the skin, and then badly affects it, so it is imperative to work with rubber gloves!

To apply this product correctly and remove the mounting foam:

1. To get started, try using it in a small area, and not wet the entire door at once. This must be done because whitish tracks may remain from Dimexidum.
2. Pound “Dimexidum” over a small area of ​​the door for 30-40 seconds.
3. The crust of foam will not be able to peel off, but it will become transparent and easier to come off the door surface.

What is polyurethane foam?

Inside the cylinder with mounting foam, two main ingredients are under very high pressure:

1. A prepolymer in a liquid state of aggregation, which is a complex of complex organic compounds:
   • hydroxyl terminations of polyalcohols;
   • isocyanate groups of methyl phenyl diisocyanates.

During the exit from the container, during contact with air, as well as with water, a specific prepolymer polymerizes and, ultimately, a sufficiently strong polyurethane foam is formed.

2. Propellant is a mixture of gases in dissolved, liquid in the prepolymer, as well as in gaseous form. The main task of these substances is to push the foam out of the balloon and then form a large number of bubbles.

 

Sealing foam has a very high adhesion to a large number of building materials, which during installation is a huge plus, and during cleaning creates considerable difficulties.

Pollution prevention

When working with sealant, be sure to remember that the best ways to remove polyurethane foam from any surface are preventive measures. First of all, this is achieved with the right skills for working with foam. It is convenient to protect surfaces from contamination with masking tape. After the foam has completely dried, the masking tape is eliminated along with the impurities that have fallen on it.
