Safety of Using Polyurethane Foam for Inserting Flush-Mounted Boxes into Outlets

Yeah, they ordered. End of the world ! Bricklayers / plasterers rule the construction site !!

And didn't they say that a bricklayer and a forester are not a craftsman?

Well, because the electrician rules the construction site. A bit of common sense.

The electrician is the most important at the construction site. Then nothing for a long, long time.

You have the effects of cooperation with plasterers -



And here the bricklayer-forester installed ... the lid from the foam container. She was supposed to do for the can :P

Ok, I will tell you how it works in my area because we still do not understand ... An electrician makes wiring on the wall in the place where the box is to be embedded, cuts a hole with a hole saw larger than the box, forks the cable's approach, puts the boxes, puts the wires into it and leaves it. A plasterer comes and plasters, then he also manages the cans, if an electrician notices the wrong cans, the plasterers correct them, if you still talk badly with the investor because the manager is probably not on the construction site anyway. Then the investor is to oblige them to fill them correctly.

Of course, everything still depends on the general arrangements between the electrician - investor, plasterers - investor.

Ps. I do not think that the electrician is God at the construction site and certainly not the most important. If you think so, you will probably be led out of the mistake someday, maybe a gas worker or an inspector or a manager, and most likely it is an investor.

I do not have a photo, but under the tiles I saw a total lack of a can because it is not needed the paws catch the plate what the can for better to make a hole

They won't be on time anymore. I am too old and I have been doing too much or doing too much.

Then the investor is to oblige them to correct filling .

Unless he sends them to the course first, it will be "correct"

Well, correctly and correctly it is a difference, but I wrote how it should look like common sense. I cannot imagine that plasterers leave places without plaster where the cans are supposed to be. I always get along with plasterers filling the cans and doing it until it is reasonably good to put something in the can. If there are plasterers who know their job, they will do it well. A similar case is with the cans that are in the plates, the one who puts the pollen is filled with the can so that the can is flush with the plate.

By the way, there are plasterers who know how to fill the cans properly ...

I have been setting up electrical installations for many years. From my practice, every tenth plasterer knows how to place the cans correctly.

Well, every tenth, but there are still such

hehe Today I showed the owner how the foam cans hold i.e. how much flew out when trying to check the installation fortunately, before painting and tomorrow the guy who finishes it all will be correcting after the plasterers who made the foam; p Laughter in the room ...

Gentlemen, I will not fully agree, I am just doing electrics in my new home and for a test I have filled a few cans with low-pressure foam for gluing styro (hard), after a few hours there is no chance of tearing them out.

Just check how this foam reacts to the flame.

I wonder why the manufacturer of cans uses flame retardant material for their production?
But "rationalizers" always know better.

Hehe, a plasterer is able to properly and properly place a set of 4 or 5 cans horizontally, according to the art.
Do not make me laugh.

I share my friend's opinion.
I use an angle template to embed the cans. Attached to the screw hole.
Using a spirit level, set the level, the template is based on the surface finish, the box is seated at the correct depth.

Gentlemen, you're reheating the cutlet. I close.
