Terrazzo floors are popular because of the characteristics of freely splicing, convenient construction and low cost. From the beginning of the industrial field to today's commercial field, the heat of terrazzo floors has not been reduced. It can be seen in supermarkets, shopping malls, restaurants and home furnishings. Brightness has always been a very bright feature of terrazzo floors. It can be said that most of them still like the color and brightness of terrazzo floors, so they choose to be terrazzo floors. However, sometimes the terrazzo surface will be dim after the completion of construction, and the gloss can not reach the standard obviously. As for why such a problem occurs, most people are not aware of it. The following is a brief introduction to the reasons for the poor brightness of terrazzo floor and the solution.
1. Reasons for poor brightness of terrazzo floor
1. When grinding, the specifications of the grindstone are uneven.
In the construction of terrazzo floor, the frequency of polishing should not be less than 3 times. However, in construction, the specifications of forbidden grinding wheels used are often uneven, and the second and third times of grinding stone requirements are not enough attention, as long as the stone, separator bars are clearly visible, but the construction requirements of surface brightness are ignored.
2, waxing money did not apply oxalic acid solution.
The terrazzo floor is coated with oxalic acid solution before waxing, and it is difficult to ensure the homogeneity of oxalic acid on the ground if it is not coated with oxalic acid solution but dried with powder oxalic acid. After scrubbing, the cleanliness of the ground surface is inconsistent, and there will be spots where it is not cleaned, which directly affects the effect of waxing, resulting in low brightness of terrazzo ground.
3. Use the brush method to reinforce the pulp.
The disadvantage of grouting by brushing method is that it can not eliminate the holes completely, but only form a layer of film above and below the holes. After polishing, the holes still exist, which will lead to low brightness of terrazzo floor.
Two. Solution to the difference of terrazzo floor brightness.
The difference in brightness of terrazzo does not need to be knocked out and re-constructed, but only the use of concrete sealant curing agent can improve the brightness of the ground. The concrete sealing solidifying agent can block the pore of terrazzo surface and make it a compact whole. After multi-level polishing with professional polishing machine, the terrazzo surface can show marble-like luster. And the gloss will also increase with the increase of use time.
In addition to brightening terrazzo floors, concrete sealants can also achieve hardening, strong, anti-wear, dust-proof, waterproof, chemical erosion resistance, salt resistance, oil pollution resistance, safety and environmental protection of the sealing effect, but also increase the service life of the floor, up to 30 years.
