A few words about the sandstone
Natural stone is much more pleasing to the eye than even the most beautiful, but artificial finish. And no artificial material can match the strength with this type of rock - sandstone, which, in fact, is compressed for millennia by sand.
It can not be said that sandstone is the hardest stone, it does not occupy the highest positions on the Mohs scale( 2 times weaker than diamond), but can be processed. The color of sandstone can be different, which makes it more attractive when decorating houses.
Sandstone laying does not respond to any specific standard, each chooses the size of the stone and its color, even the type of masonry can be chosen independently. Everyone will find something that he likes more: someone likes stones of large sizes and the same, someone prefers small stones or, in general, a combination of different sizes. The technology of laying sandstone as such is absent, the standard of beauty does not exist.
Preparation of walls and materials for finishing with sandstone
So, you decided to lay sandstone yourself, then decide what exactly you want to do, what is needed for this, and go to the construction market. Buying sandstone, the tile of which will be thin( up to 10 mm), keep in mind that even though it should be well attached, for example, to the wall, but after all, it will also be supported by another tile. In this case, the thick one will be more reliable.
Continuing to discuss how sandstone laying is carried out, video materials on this topic can not be ignored, because the clarity in this matter will not be superfluous. Before putting the sandstone on the wall, it will be necessary to nail down on it a special metal mesh. The net is fastened with large washers with holes through which the dowels are pushed in for quick installation.
Sandstone slab laying provides concrete walls, not brick walls, as they quickly crumble. Adhesive mixture can be ordinary cement mortar with the addition of PVA glue.
How to pave a sandstone path?
When designing a sandstone path, do not forget that the material is original, so try to keep this identity by picking stones to each other, by texture and color. Do not get carried away with a sharp stone, as it will lose its natural appearance. When laying a stone, it is necessary to wash the joints formed between the stones. It is important to do this on the same day, so that the solution does not "grab".
Doing sandstone paving, you need to remember one condition: the temperature should not fall below five degrees a whole month. Otherwise, the tiles will start flying off. Basic requirements for work:
- Paving can be carried out on ordinary cement mortar, which distinguishes it from other types of stones.
- Specially left unevenness of the stone gives an original look to the cladding.
- The thickness of the stone must be at least thirty millimeters.
- The place where the sandstone is laid should be cleared of grass and leveled.
- When laying a stone, be sure to press it in addition.
For greater strength, a sand and gravel substrate is suitable, which is poured into an even layer, is rammed, and then the stone itself is laid on the mortar. At the end of the work, be sure to rinse the seams with water to clean the sand and cement of the track.
