How to deal with the solid wood door stained with styrofoam

Once the styrofoam gets on the door, don't touch it, wait until it's dry, just shovel it off with a spatula and wipe off the mark with gasoline or paint thinner. But be careful not to remove the door skin, if the door is painted, you can't use paint thinner and gasoline. It is best to wash it with a dry towel and wipe it off.

As the name suggests, styrofoam is a kind of glue with foaming properties and adhesive characteristics, which is mainly used for filling, sealing and bonding at the edge joints of building doors and windows, expansion joints and holes of components. It is a polyurethane elastomeric sealing foam that relies on moisture curing. Styrofoam is composed of polyurethane prepolymer, foaming agent, catalyst, crosslinker, etc. filled into a high-pressure resistant iron can, and filled with propane and other gases.

It is divided into two types: gun type and tube type, the gun type is required to use a special polyurethane foam gun, and the tube type is equipped with a disposable hose.

It's a bit difficult because polyurethane styrofoam is very sticky and has a very strong adhesion, and there is currently no very effective way to remove styrofoam. However, a suggestion, if the styrofoam sticks, you should be careful not to flatten it, if you press it, it will make the styrofoam bond more tightly, you should let it cure naturally, so that the contact surface is not large, and you can directly pick it off or rub it off when it dries. Now the only way to do this is to cut it off without damaging the paint finish.

If you accidentally spray on the door, don't flatten him, don't wash it with detergent, and when it's dry, it's good to pick it off, if you flatten, you try to soak it in hot water and wipe it with a hot towel, and if it doesn't work, you can only use mechanical methods to cut it off.

There is a special styrofoam cleanerDo not use chemicals. has an impact on wooden doors. It is recommended to take a look at the market, which generally sells styrofoam.

Here's how to clear it:

1. If the styrofoam is sticked, do not flatten it first, and then buckle it off or rub it off directly after curing, without damaging the paint surface.

2. Since the foaming agent contains egg white, it should be wiped with wet and hot water with a towel.

3. If the above methods do not work, scrape them directly with a blade, if they scrape the surface of the skin, polish them with 320 sandpaper, and then brush them with the place where the paint has been polished, and the paint is the same.
