The construction of the NFJ metal aggregate explosion-proof surface material surface layer starts from obtaining a flat and bleeding free foundation concrete, until all surface layer operations are completed. It is mainly divided into the following stages:

When the surface layer concrete is initially set, spread NFJ metal aggregate anti-static and non igniting surface layer material. The NFJ metal aggregate anti-static and non igniting surface layer material is a dry mixture of high-grade cement, silicon powder, and intermediate agents, with different packaging according to different transportation and storage environments. In order to spread evenly, the material is required to be spread in two stages. The spreading amount is calculated by technical personnel based on usage and warehouse area, and the amount must be guaranteed.

Spread 2/3 of the total amount of NFJ metal aggregate anti-static and non igniting surface material (base material) evenly on the finished cement floor for the first time. Use a polishing disc to compact the burrs and trowel back and forth multiple times. Use a manual trowel to cooperate with the construction at fine edges and corners, and determine the next process time based on temperature and humidity;

Spread 1/3 of the total amount of NFJ metal aggregate anti-static and non igniting surface layer material (fabric) on the finished cement floor for the second time, with the spreading direction perpendicular to the first time. Use a polishing disc to compact the vertical and horizontal staggered operation of the trowel, at least twice or more;

Use a troweling machine to press and polish the blade in stages, with a vertical and horizontal staggered operation for 3-4 times, until the surface is fine and shiny (construction personnel must wear soft flat shoes to avoid damaging the surface);

The corners that cannot be operated by machinery shall be roughened and polished manually by professional Plasterer.
