With sand-lime brick wall in 3 steps

Limestone can also be walled by a layman quite easily. Both with a normal mortar joint and without visible joint in Dünnbettmörtelverfahren the limestone can be bricked. The sizes of the stones often fit so meaningfully that only a few cuts are necessary.

1. Foundation and preparatory work

No matter how short it may be under any wall, it must have a solid, straightforward foundation. The foundation should be wet with the quast before the walls. Hit a nail at the beginning and end of your wall and pull a tight string between them. So you do not come from the direction of building the wall.

If you are not very experienced in walling, you should always mix only a little mortar. For this, four parts of sand and one part of cement are mixed with each other and with a little water. The sand should not be grosser than about five millimeters.

2. Align the first row

Along your taut string, apply a layer of mortar about two to three centimeters thick. This location should be slightly stronger than the later joints. In addition, the mortar layer on both sides must be about one to two centimeters narrower than your sand-lime brick is deep. So the stone can be well pressed into the mortar bed, without too much spilling out.

You should immediately pick up excess mortar, but do not throw it away, but give it back to your mixture. Place the long board on your first row and use the spirit level to check that the stones are absolutely straight. If this is only checked with the spirit level, the series can still go wrong. You should also check the alignment with the string again with the board.

3. walls in the composite

In the second row, place each of the sand-lime bricks half the length of the previous stone. So the vertical joint should be about in the middle of the underlying stone. Here, the gap may only be just under a centimeter thick. Always remember to resume any bulking mortar immediately.

Tips & Tricks

Always dip the sand-lime bricks about half way into the water. So the stone better absorbs the mortar mix and does not bind too quickly. However, the stones should not be placed completely in the water, then they suck up too much water. If you have to take breaks during construction, you should remove all mortar residues on your wall and protect them from the weather. If you want to continue building later, you should wet the existing wall parts well with the Quast again.
