Most self-builders choose aerated concrete or other large blocks for self-laying. Working with them is much faster than with ordinary bricks. But the process can be further accelerated by assembling the following adaptations. With its help, you can evenly apply the solution to several blocks at once in almost one movement.
- Edged board 100-150 mm wide;
- self-tapping screws;
- comb trowel that is wider than the block.
The process of making the mortar applicator
To make adaptations, you need to cut 2 blanks from the board. They should have one oblique end. To get it, the parts need to be sawed off with an indent from the edge on one side 40 cm, and on the other 42 cm.It should get a slope of 2 cm, while the second end remains straight.
The third board with straight ends at 90 degrees is also sawn off. In length, it should be the width of your cloud, plus the thickness of the two previously prepared slanting boards.
Of the three boards, you need to twist the U-shaped body of the device. This is done on the block. Slanting boards are located on the sides, and the third is screwed to them from a rectangular end. It must be shifted upward by 2 cm, creating a step. The sides are positioned so that the sharp corner is at the bottom.
A notched trowel will serve as the fourth side of the device. It is screwed onto the bevel of the sidewalls with self-tapping screws. Like the board opposite, it should be raised 2 cm.
The resulting device is installed on a stacked row of blocks, and masonry mortar or glue is poured into its frame. It is spread with a trowel towards the trowel. Then the device is pulled along the row. As a result, a uniform layer of solution remains.
Blocks for laying on this pillow must be set up in advance, poking up, close to each other. Thus, the solution is applied to their end. After that, the blocks are immediately laid out in a row, and trimmed with a mallet along a lace or bubble level.
The device allows you to work much faster than manually applying glue. He lays down exactly the same layer. In addition, the sides of the blocks remain clean, so the masonry looks much neater.
