The rapid frozen of the mounting foam contributes to a strong bonding, so it is difficult enough to clean.
It happens quite annoying the situation when when installing the door it does not work out to achieve that accuracy during the faving, which would like. So, the door is evaporated by mounting foam. And the question immediately arises: what to clean the mounting foam? The person is unprepared in this business misses the precious time, and to clean the surface after the composition of the composition will be much more complicated. Not yet frozen composition is purified much easier. Therefore, when planning works in which the installation foam is intended to be used to worry about its purification, which is an indispensable condition for the use of foam.
It is well known that this tool includes a polyurethane foam, which has a high degree of adhesion (grasp). Adhesion is considered an important characteristic, and due to this property, foam found its use when installing doors and windows. Instant straightening of the composition contributes to a strong gluing part of the parts. It is for this reason that it is quite difficult to clean it. But if it happened, it is necessary to react immediately.
How to eliminate not yet dried mounting foam with doors?
Acetone is used when cleaning not yet thickened foam.
If, blowing the lumens when installing the door, it is found that the composition hit the surface on which he should not be completely left, then it should be removed and made it as quickly as possible.
Trying to carry out this through water is useless. The more to contact the substance with water, the faster it will begin to dry out.
On ready to stand acetone. They need to wash off the unwashed foam. It will also dissolve a liquid mass right in front of the eyes, because it has not yet formed tight connections between molecules, which would have gripped them with great strength. When the mass is frozen, acetone will already be powerless against her.

In the hardened composition of the molecules are firmly connected and form a hard frame. Therefore, if the moment "X" is missed, the acetone will be useless.
What do the metal door clean when the foam froze? After drying the assembly mass and its complete polymerization, remove the mounting foam is presented exceptionally mechanically. Although it does not make sense here to panic. In most situations, foam is removed well. However, everything will depend on the material on which the assembly composition hit. On the metal door, also not painted at the same time, the trace will not remain from the presence of foreign substances here. If the mass was not a tree, it is not a tree, then it will have to be a little longer.
Of course, sometimes it makes sense to apply special chemical compositions to remove the mounting mass. Only in this case should be prepared for the fact that with some layer, paint will have to part, as such a means is simply implant.
Special foams
Cleaner mounting foam is applied to a quarter of an hour before the process of removing foaming bunches.
Consider the application of the use of special cleaners for foam in more detail. The cleaner specially intended for the foam is produced by the same company that produces the assembly foam itself. Therefore, every product is inexpensively for each product.
In addition, the presence of a suitable cleaner for those who work with foam is simply a mandatory requirement. They can be cleaned by different surfaces, including valves, equipping mounting guns or cylinders. It is very useful to clean the treated surface before the process of applying foam over it.
Such a substance is intended specifically to eliminate the consequences of pollution arising in the process of using the assembly mass, both in a situation with a freshlylandized composition, and with already a little scenes from it. Before cleaning the mounting composition with the door to the means, we emphasize the initial need for cutting it with a sharp blade. After that it is possible to use the cleaner to eliminate foam. It turns out that it is not eliminated by the entire hardened yellow clutch, but only a small film on the surface after its mechanical cutting.

Using the cleaner is recommended with extreme caution. You should try not to disseminate it to unpolluted areas. This is due to the fact that the active substances that make up the means have a negative impact on some materials, leaving the defects on them. And the tree here is also no exception. Special accuracy in cleaning requires surface painted and lacquered.
Before the removal process, the cleaner for a quarter of an hour is caused to remove foam bunches from such doors. This technique will help maximize the hardened material. It will only be left to remove the residues of the mass with the help of cleansing napkins.
Cleaners used to remove from different surfaces of the mounting foam, will rise and for maintenance of the mounting pistol. The latter is required to wash or clean, for which the cylinder with a cleaner is installed in the socket in which the cylinder with foam is mounted. By unscrewing the outlet, it is trying to keep it away from ourselves for security purposes, withsting some distance. Next, they press the lever several times, which allows the substance to penetrate into the tube. So it will pass through the gun, thoroughly eliminating the remaining foam from it.
Elimination of foam without cleaning cleaners
The mounting foam can be removed with your own hands using a scraper or knife.
If chemistry is decided not to use, then remove the mounting foam from the door canvase is possible with its own hands. For which it is more correct to arm a scraper or a knife (well-sharpened), a sponge for washing dishes (on one side of which there is grungy material). A tight movement of the hands scrape the clutch. Traces of small scratches in the future can be disguised as a polyrolla.
When the hardening passes very badly, you can try to apply dimethyl sulfoxide. Such a means is sold in the pharmacy network and is called "Dimeksid".
Please note: "Dimexide" is easily absorbed by the skin of the hands, having an adverse effect on it. Therefore, all manipulations with the participation of this medicine should be carried out exclusively in rubber gloves.

It is recommended to initially carry out an experiment on a small island of the surface. Washat "Dimeksid" the entire door should not immediately follow, because it can leave behind whitewashed traces. Within 30 seconds, the drug is triturated on a small block of surface. Foam crust will not fit, but discharge and will become much more fuel to break from the surface.
By purchasing a mounting foam, do not forget about the cleaner for it.
Consider: who competently prepared for fossing, he will get less trouble in the future and an ideal clean door without "surprises".
