Stone maintenance masters who have experience in repair know that small cracks are prone to occur in the process of stone use, especially the stone for floor decoration. There are many reasons for the cracks in the stone, which may be due to the impact of heavy objects, or it may be due to the corrosive effect of a certain substance on the stone, and the natural weathering effect. Regardless of the reason, what the stone care master has to do is to mending the stone immediately. Use patching agent to fill the gaps between the paved stones with the same color, so that the stones can achieve an integrated effect and increase the beauty of the stones.
Stone maintenance and renovation project
Wax cleaning, fully dry the ground, fill in the stone joints, natural air dry, flatten, polish, rust yellow treatment, protective treatment, crystal treatment
1. Waxing cleaning--we use marble **waxing water, after comparing the performance of several kinds of waxing water at home and abroad, and price comparison, we chose a certain brand of waxing water with the most cost-effective price, and mixing it with water. Waxed the stone surface and scrubbed it with a dust scrubber. In order to avoid too much water seeping into the stone surface, we scrubbed it while using a vacuum cleaner to absorb water wax and stains.
2. Ground into dryness-this process is divided into two kinds of operations.
①The water stains on the joints of the original stone surface are heated and dried by a far-infrared lamp.
②Moisture on other surfaces, let it dry naturally. As a result, water stains have been completely removed, economical and reasonable, and customers are very satisfied.
3. Filling the stone joints-using the method of filling joints to solve the infiltration water of the stone joints is an important preventive measure. Must pay attention to caulking work. The caulking material should have good adhesion, no powder, waterproof, grinding and polishing, we use the German super marble crack tonic, according to the process to fill the gap (filling surface and the stone plane flat, the filling should be even , To prevent omissions.) And after more than two hours of drying and curing.
4. Leveling, grinding and polishing--In view of the fact that the stone surface has been waterproof before, which causes the stone to change color, we did not directly use the method of leveling and grinding, but first use O# steel wool with ** equipment for grinding, polishing and grinding. The discoloration layer on the surface of the stone is removed, revealing the original background color of big gray. Fortunately, because the degree of penetration of the protective agent into the stone surface is very light, we have received good results only with the above-mentioned scheme, and the discoloration problem that we are worried about has been treated. The second set of plans is to use marble diamond polishing pads, water polishing pads, and step-by-step polishing, which is not used.
5. Rust yellow treatment--According to the overall plan, first polish the areas with serious rust spots with steel wool to remove the floating rust on the surface, and then use the marble rust remover to remove the rust.
The rust removal process is as follows:
Clean the surface, dry and wet the rusty surface, paste a white paper towel and add a rust remover cover, plastic film, and seal the surface. Aging treatment for 3 hours, neutral detergent cleaning, washing and drying (the rust that cannot be removed at one time can be reprocessed)
6. Waterproofing and protection-in order to avoid water stains, rusting, and other pollution of the marble in the future, it is our plan to protect the ground after grinding. We have learned the lessons of the original protection from discoloration and selected several For a better waterproofing agent, experiment with the same stone, on the one hand to check the protective effect, on the other hand to check whether the color of the stone is changed, and to determine the process dosage according to the water absorption rate. After making the above preparations, we have carried out protective treatment on a large area of the ground.
For protection treatment, we mainly focus on the following processes:
① Use stone cleaning supplies to clean the stone surface
②Fully dry
③Spread the protective agent evenly, moisten the stone surface, do not miss the brush, not too much, to prevent accumulation, the former affects the protective effect, the latter affects the appearance and increases the difficulty of cleaning.
④Under natural conditions, ventilate and dry for more than 24 hours. Here we need to emphasize that in the process of ventilating and drying, we must pay special attention to waterproof and dustproof, and also pay attention to the weather conditions to prevent the stone from discoloration and failure of protection caused by fog and rain.
7. Crystal processing: After the upper process, the crystal can be processed. We use Spanish crystal hardening agent. According to its use process, the brightening agent is pressurized by the equipment and polished at low speed to make the agent produce heat. Chemical reaction, so that the ground forms a non-slip hard mirror surface. After crystal treatment, it is new and bright, and the previous water stains, discoloration, rust spots, stains, etc. are wiped out.
