The question of how to effectively wipe the dried foam from the metal door, often occurs in the masters during construction.
Without the contamination of hands, tools, surfaces, work is not bypassed.
That's why it is worth preparing the necessary tools that will help clean the door of the sealant.
Before using this or that agent, it is important to evaluate the nature of the setting of the means by which the slits are sealed.
After all, fresh pollution can be washed away in a different way than that which has already frozen.
Foam in its composition has a polyurethane foam. It has a high degree of setting.
Instant hardening is one of the qualities that made the sealant popular during construction work.
Elements are stuck together very firmly, so the tool is so difficult to wipe off.
But if the product has got on the door and other objects while it is getting stained, it's time to orient and remove it, while it is still frosty. Later, it will be more difficult.
The composition of the sealant is very complex. The cylinder contains a complex of isocyanate groups, as well as hydroxyl terminations of polyalcohols.

In addition, the cylinder contains a mixture of gases that are in gaseous and liquid forms. Their task is to forcefully push the composition outward and form a large number of bubbles in the mixture.
Coming out of the cylinder, the mixture of organic compounds is contacted with air, after which the polymerization reaction immediately proceeds. A few minutes later, the sealant hardens.
Being a complex chemical compound, a means for foaming crevices, seams for the installation of metal, wooden doors, plastic windows requires knowledge, experience, and the use of protective equipment.
Getting to the surface, the foam is capable of several times increase in its volume. Calculate the amount of sealant is difficult, so the substance often falls on doors, windows.
This is not included in the plans for construction. It is necessary to act without delay, therefore it is important to study instructions on how to clean the sealant from the metal door and other surfaces, and do not spoil the appearance.

What kind of foam cleaners do I need?
Specialists recommend the use of a foam cleaner, which is produced by the same manufacturer that manufactured the sealant.
Such a means of pollution are removed very easily, without causing the surface of harm.

Special tool can wipe not only doors, but also other contaminated surfaces, cylinders, guns for mounting foam, valves.
Masters who have been working with polyurethane foam for a long time are advised to wipe with surface composition before carrying out repair and construction work.
Since they will come into contact with the means for sealing, the removal of contamination is not difficult.
The composition for removing the mounting foam can be washed as fresh traces of sealant, and those that have already seized.
Before working on contamination with the compound, it is necessary to carefully remove the material cap to seal the joints.
As a result, the tool will not act on the entire piece of polyurethane foam, but only on the thin film that remains on the door.
The cleaner should be used very carefully, since it has a negative effect on the hands.
Also, do not put it on clean areas of the door - they can form defects.
To remove the mounting foam from the door, apply the compound for 10-15 minutes. During this time the foam will soften as much as possible and the contamination can be removed with a soft sponge.
Removing fresh dirt
If there is no special agent that will help wipe off the fresh mounting foam, then other compounds can be used. Water to take for these purposes does not make sense, because when it comes into contact with her, the sealant will wither faster.
You can use acetone. It will dissolve the liquid agent to seal the cracks and seams fairly quickly, thanks to the yet unformed bonds between the molecules of the substance.
It is necessary only to seal the sealant, acetone for removal of pollution will be useless.

Acetone can be used to remove dirt from a metal or wooden door. If the door has elements of plastic or vinyl, then you can not get acetone on such surfaces.
Otherwise they will peel, lose an aesthetic appearance, will not be able to perform their functions.
Masters who work with the installation of doors, windows, work with the tool "Kosmofen".They can clean the sealant not only from the metal door, but also from the plastic.
This tool has a drawback - on sale it is represented by a volume of 1 liter. If you need to clean the contamination only from the door, this option will be unprofitable.
Removal of the foam that has not yet solidified:
- Take the scraper and carefully, taking care not to smear the composition over the surface, remove it. The scraper must be made of plastic or other material that does not scratch the surface;
- Take a sponge soaked in a solvent and wipe the place of contamination;
- Dry with a dry cloth to wipe dry the place where there was a stain.
Frozen sealant on the door - what to do?
If the foam for mounting on a metal door has time to freeze, then it will be more difficult to clean it from the surface.
It's not necessary to panic - the pollution will be removed, but for this you will have to make an effort and be patient.
Procedure to remove dried wiping foam:
- It is necessary to take a knife, a blade and gently cut off the cap of the sealant. It is necessary to make sure that the cut is as close as possible to the surface, and the knife does not damage the surface;
- The remaining layer of soiling should be moistened with a solvent and leave for 10-15 minutes;
- Sponge with a hard surface to rub the place of contamination;
- Wipe clean with a dry cloth.
It should be ready, that from the first time the means by which seams are sealed, the cracks will not be erased. The above actions will need to be repeated again until the layer is completely removed.
There is one more way that you can remove contamination - you need to take a material that is stronger than the used means to seal the cracks and scrape off the stain.
There is a "folk" way to clean the metal door from the sealant. In the pharmacy you need to buy dimethyl sulfoxide. For sale it is presented as "Dimexide".
On a small area of the surface you need to grind the product and check that no whitish spots form. Rinse dimexidum dried polyurethane foam for 25-30 seconds.
It does not come off the surface, but the film will become very thin and soft - it can be easily removed. When working with Dimexide, it is worthwhile to be careful.
It has a negative effect on the skin of the hands. Work with this tool is recommended in gloves.
You can try to clean the sealant with ordinary sunflower oil.
Before applying it, it is necessary to cut off the main part of the contamination, which acts as a cap. It is important not to scratch the surface of the metal door.

On the remains of polyurethane foam, apply a layer of oil and wait 15-20 minutes. During this time, the surface of contamination will become much softer that it will be easy to remove it from the metal door.
After the polyurethane foam has been successfully peeled off the surface of the door, it is necessary to remove the oil grease stain.
For this, a little soap is diluted in water and a place of soiling is wiped with a soft sponge or cloth.
All these methods are effective for wiping sealant from a metal surface. If during the installation of interior, entrance doors there was a pollution, it can easily be removed.
Pollution of foam is better to warn than to apply afterwards, spend money on funds to remove stains.
Before you start working with the cylinder, it is recommended to buy a paint tape or tape.
They need to glue the door frame, the door leaf on the installation side, and the floor under the foaming area. Do not forget about the part of the wall adjacent to the slit or seam.
After working with the sealant, the paint strip is easily separated from the surfaces together with the polyurethane foam that has fallen on the tape.
The metal door will remain clean and it will not need to be wiped off in various ways.
