How to install the pu line? You can also complete the installation by yourself, let’s take a look!
Construction method: According to the construction case, the acoustic substrate is divided into two construction methods
1. If the substrate is RC mixed soil, to avoid the unevenness of the wall and cause inconvenience in future construction, fix a layer of plate (thickness is about 12mm or more) on the wall, which can solve the unevenness of the wall and the appearance of the line board after construction. The phenomenon of bending.
2. Lay the cut wooden core board on the size position mark
3. Use steel nails to nail, and nail the wooden core board to the wall
4. Mark the size and position of the upper line board on the wall at the junction of the ceiling street
5. White glue or nail-free glue is evenly applied to the contact surface of the line board and the wall and the two line boards
6. The PU line board is aligned and attached to the originally marked wall and ceiling
7. The line board is aligned and attached to the originally marked wall and ceiling
8, nailing skills. After 2-3 nails are placed in the center of the long line board,
9. When the PU wire board is nailed, the distance between the nails and the nails is about 20 cm, and then from the right.
10. After the PU wire board is nailed, take a damp cloth to wipe the spilled white glue or nail-free glue clean
11. Gap filling: Filled with AB glue, which is characterized by high hardness and toughness; and high dust resistance and moisture resistance after filling
12. Use water-based silicone to replace AB glue (Neutral silicone is not allowed to be used, otherwise it will be impossible to paint)
13. The previous batch of soil: gypsum powder can be added to increase the hardness of the batched soil. The mixing ratio of the batched soil and the gypsum powder is about 3:1 to 5:2 (volume ratio), depending on the speed of the individual. Increase or decrease the amount of gypsum powder.
14. Sanding with sandpaper: Use sandpaper to attach it to the rough parts of the wire board and grind it smooth to facilitate painting.
15. Painting: Use a spray gun to spray paint on the wall or cabinet. The difference from brushing is that there are no brush marks, so it is commonly used in indirect lighting, so that when the light is illuminated, no brush marks will be seen.
16. The finished product of the line board is presented: between the corners of the line board, pay special attention to whether the line and the texture are consistent, and the effect of tightness must be achieved.
