Paving Method Of Commercial Carpet Tile

Requirements on the ground:

1. The cement floor needs to be self-leveling.

2. The ground is flat, clean, dry, free of oil, sand, unevenness, and adhesion. The cracked or irregular surface of the ground should be smoothed and smoothed with a smoothing agent. The moisture content of the ground base layer is less than 7%, and the PH value of 6-8 is the most ideal, otherwise the PVC carpet tile will produce peculiar smell due to hydrolysis.

3. It is recommended to use an infrared pay-off instrument for installation and leveling of the network floor. The accuracy of the entire floor should be controlled within 0.5mm/m, otherwise the corners and corners of the carpet will not be firmly bonded.

4. Remove the protrusions on the ground as much as possible, including all kinds of conductive lines, otherwise the piles of the protrusions will be stressed when the carpet is used, and it will be easy to get dirty and easy to break.

5. Avoid cross-construction, especially if corrosive liquids containing marble glue, pine perfume, repair paint, etc. drip onto the carpet, it will cause the carpet to discolor, which cannot be compensated. When cross-construction is necessary, precautions must be taken to avoid contaminating the carpet.

Three common paving methods in the market.

1.Self-adhesive installation method:

Use a kind of 70mm*70mm self-adhesive plastic rigid sheet to paste the four corners of the carpet tile installation method. Its advantages are that it uses less glue and has little peculiar smell, which is suitable for small area and popular installation. The disadvantage is that the self-adhesive installation method is a single-sided gluing, and only the four corners of the carpet are pasted, and there is no sticking to the ground, so the sticking force is small. In the later use of the carpet, especially when carrying or moving objects on the carpet, cleaning the carpet, vacuuming the carpet, and rubbing the seat rollers, the carpet joints are usually cracked and the carpet surface is uneven. , Affect the service life and appearance of the carpet. Moreover, this method has a slow construction speed, high cost, and poor effect, and is not suitable for large-area use.

2. Installation commercial carpet tile method of stainless steel thorn piece:

Use steel nails to fix the square stainless steel spikes with a size of 70mm*70mm with a round hole on the ground, and then pry the four corners of the four carpets on the stainless steel spikes with a spatula. Its advantage is that it avoids stickiness and has no peculiar smell. The disadvantage is that the connecting points of the four corners of the carpet are about 0.3mm higher than other areas. When walking, you can clearly feel the uneven surface of the carpet at the connection point. The problems caused by the use of the carpet are the same as the self-adhesive installation method.

3. Water-based glue installation commercial carpet tile method:

The paving method is to coat the floor with glue or make a 10 to 15 cm wide square grid at the joints of the carpet, and then place the carpet on the glued floor. Its advantages are that the carpet is firmly attached to the ground, the carpet joints are flat, anti-rolling, and strong friction. The carpet is not easy to crack and deform when vacuuming and cleaning, and it is relatively easy to replace or repair the carpet. The disadvantage is that the newly installed carpet has a slight glue smell. It is recommended to use environmentally friendly water-based glue, such as first-line brand glue such as Bangdun and Nanbao. This kind of paving is also the most common and mature paving method for carpet tiles used in large office buildings and office buildings worldwide.

The actual paving operation of the engineering commercial carpet tile on site:

(1) Necessary materials:

Bangdun hydrosol (or other similar water-based glue), scraper, roller brush, flat spatula, infrared pay-off instrument

(2) Operation method:

Vacuum the ground, move the carpet in place, use the pay-off instrument to use the two walls at the door as the coordinates and combine the specifications of the carpet to brush glue. For example: pave a 50cm*50cm square carpet, make the distance between the two lines of the coordinate and the wall ≦50cm, start applying glue from within the coordinate line, and start paving after the glue turns from white to colorless, and then pave a large area at the end. Close.

(3) Paving requirements:

When paving, it must be constructed in an orderly manner according to the arrow direction on the back of the carpet and the design requirements. Regardless of forward or cross paving, use a flat shovel to shovel the seams up, down, left, and right to avoid leaking seams, especially for plain loop pile carpets. Before paving in winter, it is recommended that the carpet be equilibrated at room temperature for 24-48 hours. After the carpet is installed, open doors and windows for at least two weeks for ventilation. If the windows cannot be opened, indoor and outdoor ventilation devices must be used.
