One.Solid brickCan I apply cement directly onto the wall?
Using cement mortar on glazed bricks can easily lead to air pockets or detachment. The strength of the bond between the glazed brick and the cement mortar mainly depends on the water absorption rate of the glazed brick. A higher water absorption rate results in a stronger bond, while a lower water absorption rate results in a weaker bond. Glazed bricks have a relatively low water absorption rate, so they are not suitable for bonding with cement mortar.
Concrete mortar is inherently a rigid material. once concrete mortar has hardened, its strength is generally high. The adhesion between concrete mortar and the wall surface is a mechanical force. It relies on the mechanical adhesion between the pores on the back of the tile and the hardened concrete mortar.
Two. What type of adhesive is recommended for applying to solid wall bricks on walls to prevent detachment?
1、Prepare the substrate by cleaning the concrete wall. Apply full-body tiles using tile adhesive. Mix the tile adhesive powder with water according to the recommended ratio using an electric mixer until a smooth, lump-free paste is formed. Use a notched trowel to evenly apply the tile adhesive to the back of the full-body tiles, creating a patterned effect. Then, press the tiled surface onto the wall surface.
2. Apply the wall covering by pressing the entire brick onto the wall surface. Ensure that the bricks are laid from bottom to top, controlling the width and length of the laid area.
3. Measure the left and right lengths of the background wall. The vertical and horizontal lengths of the background wall sides, as well as its front-to-back length, must be consistent, maintaining the fixed tile laying angle and marking the height of the background wall.
4、Lay the entire brick wall layer by layer, ensuring that the edges of the tiles are vertically offset from each other as you move upwards during installation.
5. When laying tiles, pay attention to the timing. The tile adhesive should be used within two hours after mixing, to avoid a decrease in its bonding ability after it has hardened.
