After the floor or countertop of the home is decorated with terrazzo, the surface of the terrazzo has an old state for a long time, and it does not look like new. At this time, it needs to be refurbished, but how to refurbish the terrazzo?

How to refurbish terrazzo

1. The old terrazzo must be cleaned of stains before terrazzo mirror treatment can be performed. Terrazzo refurbishment machine grinds old or diseased terrazzo, such as yellow spots, stains, scratches, etc., to remove 1-2mm of the surface, revealing a new layer and then glaze, using a stone grinder to use different grinding discs from low to high grinding and polishing to achieve desired brightness.

2. The newly produced terrazzo can be treated with terrazzo mirror after polishing.

3. After using the special penetrating agent for terrazzo, grind with a terrazzo crystal surface machine to make the surface of the terrazzo crystal hardened bright, improve the brightness and wear resistance of the terrazzo, and then add a layer of crystal surface agent on the surface for maintenance.

4. Local maintenance or quarterly maintenance of the floor according to the number of people on the ground can maintain a good mirror effect for a long time, which can save costs and make it easier to operate.

Specific process of terrazzo refurbishment, grinding and polishing

1. Coarse grinding

The old terrazzo floor is polished with a terrazzo refurbishing machine to remove oil stains and empty layers on the surface, and eliminate uneven ground and potholes.

2. Fine grinding

The rough ground of the terrazzo is ground with a terrazzo refurbishing machine, a ground grinder and a metal grinding wheel to remove rough grinding marks. At the same time, the ground that is too high is ground and leveled to increase the flatness of the ground.

3. Repair

Fill and repair potholes and cracks (as the case may be) with terrazzo ground repair mortar. Grind the ground. Use terrazzo, ground grinder, and terrazzo grinder to further grind the ground, from coarse grinding to fine grinding, until it meets the actual requirements.

1. Maintenance works must be carried out during the renovation process. For example, pay attention to the problem of waiting a few days for maintenance after watering, because only at this time can the cement mortar be completely cured, and the future construction can be more secure.

2. In order to improve the refurbishment effect of terrazzo, it must be cleaned with water during the process of cleaning the ground. The use of pickling solution is prohibited, and the terrazzo is also prone to corrosion problems.

3. When repairing the base layer, it may lead to insufficient adhesion, so be sure to pay attention to the details during the repair process. If the base layer is not handled well, it will also easily affect the renovation of the terrazzo after repair.

4. When cement mortar needs to be filled, the consistency of the cement mortar must be appropriate, and the stirring must be uniform, so as to ensure that there will be no problems in the later stage of the terrazzo.
