Renovation of the implementation of the granite floor

Hard granite structures, rich colors and a high-level construction surface decoration materials. However, due to improper construction or wear course of time, change, tend to make the surface dull and style. This requires professionals to the ground renovation, be reinstated.
 
However, because the granite tablets of the larger grain, hard wear-resistant, and absorb water, renovation of the corner when the stone is prone to the phenomenon of gaps and water damage, it is also more difficult to improve the gloss.
 
How to develop the program? How to implement in order to achieve satisfactory economic results? Following example to illustrate a project, for reference.
 
A site inspection of

Not long ago, I undertake the city hall on the ground in a nursing home renovation, the hall of the ground about 200m, shop Sichuan red, more than four years, numerous worn surface, dark dull, some have stone surface shallow ground pit, the stone seams varying degrees of inequality and the maximum gap has 0.6mm, about 15% of the total area; gap 0.4mm, about 30% of the total area, and the remaining gap to 0. 2mm. Stamp hard step, find a loose stone. Joint sealing material off the stone, dark and dirty, very unsightly. Two pieces of stone off the entrance hall, split corner, stepped on a loose feeling.
 
From the above survey of the situation, we believe that in the Sichuan Red is the high hardness of granite varieties must be used when re-refurbished models leveling equipment and diamond film; stone about the serious drop over 40% of the total area, which determine the the renovation of the main engineering solutions to the depth of the basic ideas.
 
Second, the specific process of renovation programs
 
Our site inspection of records conducted a comprehensive analysis and research, project implementation plan presented to the nursing home and note:
 
Sample confirmed that bonding of a broken slab of a stone sealing a deal with a classification of ground water sealing a deal with a crystal polishing a hard protective treatment
 
1. Do fall on the ground to take a serious renovation of a model, as both acceptance criteria, both sides recognized model, the program can continue.
 
2. Consent of the Court agree on two slab cracking first adhesive installation.
 
3. Due to the Sichuan Red absorbent, so all the re-sealing of the stone joints, and to do waterproofing, renovation of the ground water to minimize the formation of water-soaked phenomenon.
 
4. Gap according to the size of the ground, into the depth of renovation (0.5ram above), moderate renovation (0.4ram ~ 0.3ram), shallow renovation (0.2mm ~ 0.1mm) to start renovation of three cases, grinding, protection and crystalline hard treatment.
 
5. Grinding in the renovation process, the timely adoption of high-power vacuum suction machine, suction, to reduce the infiltration of water on the ground to avoid water damage occurs slate.
 
Third, the implementation of engineering solutions
 
(A) of the sample confirmed
 
We developed the program by the hospital consent, found a gap between the first significant renovation of the stone do. As bright as a mirror to see the stone and restore the natural beauty of the original pattern, when the hospital is very pleased pleased to sign the contract.
 
(B) broken stone adhesive
 
We are under the Sichuan Red slate color, the color selected in good agreement with Billy marble glue two pieces of stone have been broken for the adhesive, the main process is as follows:
 
Section to the residue of dry cleaning a section of a transfer adhesive (refer to the provisions of blending ratio of curing agent) in a section of adhesive bonding over a 48h drying
 
In order to avoid the renovation due to vibration caused by re-grinding cracking, we attach great importance to the operation of the quality of each process.
 
1. In the section before cleaning, get rid of all the cement residue, dust, easy to take off some crushed carefully removed. And bonding the stone to check on the joints, seams not to have residue inside and small particles.
 
2. Section Cleaning: To remove stubborn dirt and dust cross section, first a strong cleaning agent Akemi Germany (10826) on the cross-section, back for a thorough clean brush, then rinse many times.
 
3. Drying: in the natural dry conditions, should be dry, should generally be dry and more than 12h, 4h dried under the sun than is appropriate.
 
4. Gel preparation: According to the stick length and gap size of the slit adjusted the amount of glue, put the number of curing agent and temperature shall be required on the level of modulation, the curing reaction after the gel time should meet the requirements, the reaction is easy too fast curing, affect the bonding, too slow is not conducive to curing adhesive.
 
5. Section Bonding: knife evenly with the transfer will be transferred as soon as possible put on a good glue joint cross section, and then align the seams, and squeeze any excess plastic force to the appropriate degree of both sides of the line as the reference standard, and corrected bond flatness.
 
6. Drying: Drying more than three days under natural conditions is appropriate, 'the section of adhesive quality is directly related to the next step of the installation and grinding, so attention must be, otherwise it will come to naught, affect the progress of the project.
 
(C) sealing slate
 
The implementation of this process aims to beautify the ground, sealed seams, dust and water, specific methods are as follows:
 
1. Special power tools with clear sewn, with d ~ lturn special bit of water to remove soil along the old dirt seam and wipe the water and mud in a timely manner.
 
2. Dry 24h or more (preferably dry).
 
3. Produced by the Hong Kong fast curing adhesive with approximately 800 stone-colored paste, the addition of appropriate amount of curing agent blend evenly, using a narrow plastic knife to wipe even one not to miss a pressure within the seam. Excess adhesive outside seam with a knife to clean up in time.
 
4. Drying: drying under natural conditions over 4h.
 
In order not to affect the progress of work, we have concrete construction, according to the basic process scheme, the use of end to end, interspersed with a reasonable construction to reduce the slowdown time.
 
Fourth, sealing waterproofing
 
1. First, along with a vacuum cleaner crevice cleaning.
 
2. Dip the brush along the crevice Polaroid even better brushing stone penetrant, permeation, and dried over 24h.
 
Five, grade grinding
 
We according to the hospital by ground and the depth of wear, moderate, and shallow renovation area, using the first high to low, high crude method of low-fine grinding process, saving time and work, and tools to reduce consumption of the device, very effective .
 
1. Depth of grinding (leveling)
 
Leveling, we drop the stone slabs in more than 0.3mm, (about 50% of the total area) higher than the first hand mill stone rubbed off the corners, to prevent the mill's higher ground leveling produce chipping stone corner, out grain phenomenon. MB then a 1093 renovation of the Italian grinder, equipped with special diamond film leveling, plus the right amount of water from the stone slab of low-end position to the ground plane leveling. Grinding machine should be driven slowly and evenly, the focus is gradually leveling end. Check the high end is grinding to a level with the surrounding stone can be taken.
 
Note: Grinding the entire peacetime, in time with the vacuum suction machine to suck the net dust, water, sand. (Grinding each of the following procedure will not go into)
 
2. Medium grinding (rough grinding)
 
1096 MB grinding machine with a small number to the queen has 50 # 300 # with granite water mill grinding chip set is gradual leveling of the rock face and some lighter Ma Hang, no more No operation. Each procedure should be a process on the left wear scar wore off, each implementation of a process before they must be left before a process of grinding dust removed.
 
3. Shallow ground (the ground)
 
The mill is targeted at the entire floor, including the coarse stone face too. The process we use a grinder than the MB a little lighter 1093 MB for a 1096 machine, with 400 # 1000 # piece of granite water mill grinding step by step, with the coarse part of the process requirements. The difference is to check the ground even white can be, there should be a good ground smooth visual effects.
 
4. Mild grinding (finely grinding)
 
1800 # 3500 # with a Water Mill films progressively polished granite, grinding process requirements themselves with part of each procedure is different after the scraper often scrape the ground using glass powder in water, check the reflective brightness, strong consistency to avoid grinding stone surface into a wavy surface caused by, or to timely renovation, polished.
