Excuse me, why is paste tile with stone powder, paste wall tiles with river sand?
Put tiles on the ground, does not appear to be falling, and floor tiles, is to put the thickness of 5 cm above the powder and cement mixture of flat ground, large amount of material, on the ground, it is easy to compaction, cement and powder with cohesive force as long as appropriate, can satisfy the requirement of use, floor tiles posted above in the leveling layer, floor tiles will put bricks before the water wet, and then glued only cement paste, is affixed to the above, it is ensured that the combination of brick and cement, stone powder mixture firmness.
1, cement mortar wall generally only a thin layer of powder, the larger particles can not meet this requirement, and the floor tiles of cement mortar generally above 5 cm, this problem does not exist, so the wall with fine sand, floor tiles can be used powder;2, because the wall is only a thin layer of cement mortar, bonding strength must be strong, can stick to the wall, otherwise, will be easy to fall, the formation of quality problems, can fine sand, sand and sand of the spacing between the inevitable small, it is easy to be filled with smaller particles of cement, so it will be cement, but can be combined to achieve both what no pores, so you can protect the brick wall and the adhesion area does not appear or rarely pore, so as to realize the brick wall and become one, as long as the cement strength is strong enough, it must firmly bond;
The stone powder is generally much cheaper than river sand, and the amount of floor tile is large, and the stone powder is much more economical and convenient to draw materials.Note: cement paste is usually used as cement wall, not cement mortar. Only when the wall surface is poor, cement mortar can be used when leveling layer is used.
