Good day. If you are going to build any building from aerated concrete or ash blocks. You will really like this homemade or a device that will save your time and nerves. And the main thing to do this adapt is not difficult. This homemade product is a box, the 3 sides of which are made of planks, and the fourth side is made of combs. Inside this device, the solution is thrown, then with the help of a comb it is evenly applied to aerated concrete or ash blocks, when moving along a row. This was done by the author of the YouTube channel, but unfortunately he did not show the process of its manufacture, but only showed it in work. Well, I hope to collect it device, you will not have any difficulty. This homemade product is made to the size of aerated concrete, which does not allow it to go sideways. The article turned out to be very short, I did not even indicate the steps and photos of the manufacture of this homemade product. Well, the device is really useful, so I decided to share it with you. And I hope that the admin of this site will skip this article. From myself I want to add that instead of boards, it would be possible to use another moisture-proof material. So that you can wash this device or remove excess solidified solution. I myself somehow laid down ash blocks and now I regret that I had not seen this homemade product before. Well, if I don’t understand what problems may arise and whether it is possible to lay aerated concrete or ash blocks in this way, then write about it in the comments. This will help newcomers and me in addition, because as they say - one head is good, and two is better. This can be done, thanks for watching and don’t forget to like.
