Adhesive foam aerated concrete. Nuances that can only be seen in practice.
Greetings to all those who have followed my building, and those who are first on my channel.
I already wrote about how I was doing laying the first row. The process continues, and with it new and interesting moments are opened. One such was the experience of using foam adhesive in vertical joints.
For me, its use in general was new (like so much else), But to be honest, I did not think it would be so much subtleties.
Adhesion.
Apparently, when I watch videos on the Internet, then either I do not see the details, either do not talk about them.
When I first started working with the foam and apply it on the block, then she constantly fell off. I did not understand what was going on ???
It turns out, you just need to wet the surface with water prior to application (It called "the instructions read"). Once work becomes easier. To do this, I began to use conventional spray.
Final assembly blocks.
This I also did not think, until you came down to it.
When the vertical joints is usually applied adhesive for aerated concrete, it all turns out simply. And try, with foam at the ends, insert the unit into the opening... I tried it, and the whole foam simply moved out.
And to be honest, I can not imagine how to deal with it until it looked.
You can cut out the blocks "cone", but there needs accuracy.
I liked the option of sawing grooves at the ends. It is done quickly and easily.
Then, the unit is placed on the solution (without foam), Is set on a par with the rest, and after that foam filled with those same grooves.
But if the block is already installed and you are not sure of a good sizing vertical seam, you can just drill holes in the full height of theAnd also fill with foam.
Generally, in these embodiments, I began to use the usual assembly foamSince there must be a maximum filling of the grooves. A good adhesive foam is just a minimal extension.
Foam foam strife.
Just want to say that I do not advertise a particular manufacturer. I describe their experience and results but how will you do not know.
In my work I still had a chance to use two types of foam, glue, and the difference is palpable.
Expanding in a foam should be minimal.
In the last article, I wrote that I had a problem with the seam thickness. So, it seems to me that the degree of foam expansion played its role here.
Here is one example:
Moreover, I have noticed that even if the first was a thin seam, the after a while it could increase.
And this foam, almost did not give extensions especially over time.
And the main thing is the expense.
- One foam cylinder (in the first example) Was enough for me literally on the two sides of the first row.
- And second, I reported to the entire series, and many more left.
I think what the foam is more expensive does not need to talk, and so clear. But here the price is more than compensated during operation.
So it is not that simple :)
And, probably, it will be more "interesting." But this is the beauty of building a house with his own hands!
