Construction of PVC wall plastic

Basic requirements for PVC wall plastic construction

       1. Ceiling works have been completed, including fire fighting, lighting and wall wiring of computer and telephone lines.
   2. Before entering the site for construction, the site must be clean and other types of work must be evacuated from the site.
   3. The indoor temperature and wall temperature should be 15 ° C. construction cannot be carried out below 15 ° C or above 30 ° C, and the relative air temperature should be maintained at 20-70%.


Treatment of PVC wall plastic base course

       1. The wall must be hard and free from grease, sand, shelling, pitting, cracks and other phenomena. The base course should be flat, dry, firm and free from dirt.
   2. The wall must be fully scraped and leveled with external wall waterproof putty (white cement and white emulsion can be used for full scraping and leveling) to increase the surface strength and facilitate bonding.
   3. If the wall with interior wall coating has been used, (this kind of wall has soft texture and is easy to fall off due to direct pasting), in order to improve the construction efficiency, save the construction cost and do not damage the original wall, the interface agent must be applied on the surface of the base course at least twice to improve the hardness of the original wall.
     4. The leveled wall must be polished with a grinder or sandpaper to improve the flatness of the bonding surface
     5. Air dry the leveled wall naturally or quickly by heating, so that the moisture content of the whole wall does not exceed 5%.
   6. The polished wall must be completely sucked by a vacuum cleaner, and the small particles on the wall must be removed.
   7. The internal and external corners of the wall to be constructed shall be straight, and the uneven corners will bring some difficulty to the laying. Before laying, the uneven internal and external corners must be treated, and the uneven internal corners must be filled and corrected with hard triangular strips. After laying, the external corners should be reinforced with anti-collision corner guards to improve the overall beauty.


Measurement and cutting of PVC wall plastic

  Through field measurement, in order to reduce waste, comprehensively consider the aesthetic degree, cut the required size as required, and give full play to the maximum economic benefits.
  cutting materials must be the responsibility of a specially assigned person.
   the damage caused during transportation shall be cut off with a trimming device before cutting.
  there are directional arrows at the back and bottom of the wall plastic, and its directivity must be paid attention to at all times.
  accurate data must be obtained from the site for each cutting,
  it shall be noted that a margin of 1-2cm must be reserved between the material and each cutting.


Construction tools

  Roller, scraper, rubber plate, mild steel ruler, medium knife, roller, cork block, etc

Paving method of PVC wall plastic

1. There are two paving methods: one is full paving and the other is half paving (i.e. dado).
   2. When paving, please uncoil the wall plastic in the order of increasing or decreasing the production volume number (identified from the outer packaging identification), and lay it in the opposite direction according to the direction shown on the back and bottom of the wall plastic, with the head and tail of the volume upside down, and adjacent to the wall plastic in the opposite row. The direction must be changed.
   3. Pop up the connecting line on the wall table according to the measured size with ink cartridge and snapping line.
   4. During gluing, it is required to scrape the glue on both sides. The whole bonding surface and the bonded surface can be thinly coated with a roller or shallow toothed scraper. Wait for 10-20 minutes to volatilize the solvent in the glue. After contacting the bonding surface without sticking hands, paste the two surfaces, connect the adhesive and press it hard. When pressing, use a cork block or roller to drive the air from the center to the surrounding direction until it is completely bonded.
   5. For the plastic overlapping part of PC wall, use a scriber or joint cutter to cut off the excess part (overlapping cutting of the joint). The joint should feel seamless, and then compact the wall and joint with a small roller.
   6. After installation, the excess glue on the wall plastic surface shall be cleaned and wiped off immediately with a wet and clean sponge cloth
   7. The top edge of wall plastic shall be trimmed with stainless steel strip by the general contractor.
