Construction process

一,Delineate the construction area

The construction area should be separated by red and white safety ropes and warning signs should be posted or hung at the corresponding entrances and exits; After entering the site, the connection of large equipment must be completed by a maintenance worker or electrician. A maintenance worker or electrician should also check the operation of these equipment. Properly place construction equipment and prohibit third parties from entering the construction area.

二,Ground damage repair

First repair the original ground broken pits, use epoxy resin or high-strength special repair mortar to smooth and compact the damaged ground pits, and then use alloy steel bits to find out the flatness of the ground and use the diamond grinding head to polish the ground as a whole.

3.1 Construction tool preparation

Tools to be prepared for hardened floor construction include: grinders, hand grinders, industrial vacuum cleaners, brooms, mops, batching buckets, resin grinding discs, scouring pads, hand trailers and sprayers.

3.2 Specific construction steps

Step 1 Clear the ground

Clean the floor with a broom or thoroughly wash the floor with water to clean the concrete floor. The ground foundation is not good, it is necessary to grind off the loose layer of the concrete surface with iron grinding blades and clean the ground, the newly poured concrete must pass the curing period before construction, and the holes and cracks should be repaired with epoxy resin and quartz mortar.

Step 2 Plain sanded

1,If the plain ground is a concrete floor, it is generally recommended to use a diamond head to open the surface (the specific mesh number depends on the site or Party A's requirements).

2,If the ground is emery floor, it is generally recommended to open the resin sheet directly (if the sand has special requirements).

Whether it is a concrete diamond head open surface or a wear-resistant resin sheet open surface, if it is dry grinding: resin dry grinding blades are 50 mesh dry grinding blades, 100 mesh dry grinding blades, and 200 mesh dry grinding blades; If water grinding is carried out: resin water mills are 50 mesh water mills, 150 mesh water mills, and 300 mesh dry grinding discs.

Step 3 Material ratio

The resin-based curing agent material is mixed with water 1:2 (1 barrel of material + 2 barrels of water), and it can be directly added to clean water and stirred well.

Step 4 Material penetration

After the ground is completely dry, spread the well-proportioned material evenly on the ground. During the penetration process, push the material evenly with a mop or water scraper to allow the material to penetrate into the concrete. Once again, you need to be reminded that before applying the material, you must ensure that the ground is completely dry so that the material can be fully absorbed by the ground. The material soaking time is generally about 1 hour, to ensure that there is a thin layer of material on the ground surface (because alkaline materials will become viscous with time, and finally the material residue on the ground surface is too thick, which not only wastes materials but also brings costs to subsequent grinding; If the surface material is too small or partially absent, the final ground is prone to color difference and affect the final effect).

Step 5 Crystallization grinding (subsequent dry grinding)

When the curing agent and concrete react to the ground is completely dry, the grinder is replaced with a 400 mesh resin dry grinding disc to polish the ground, and the curing agent crystals after the ground surface is completely dried and polished clean. In the grinding process, it is necessary to pay attention to the uniform grinding, do not miss the grinding, the corners and other positions that are not easy to grind can be polished by a hand grinder, and the horizontal and vertical cross grinding. After sanding, use a dust pusher or ash pusher to clean up the ground dust.

Step 6 Preliminary polishing

After the 400 mesh dry grinding disc is polished and cleaned, directly replace the grinder with an 800 mesh resin grinding disc or dry grinding No. 4 piece, grind the surface of the ground, and pay attention to grinding and polishing. After sanding, clean the ground with a mop.

Step 7 Finally, fine polishing

After the dry grinding plate 800 mesh or No. 4 piece is polished, the grinder is replaced with a 1500 mesh resin grinding plate or No. 4 piece to polish the surface of the ground to achieve the effect of beautiful and bright ground. After sanding, clean the ground with an industrial vacuum cleaner.
