Stone curing agent use method

1) Drying stone slabs with an oven or gas gun. Some companies use stone-based curing agents to save costs without first drying the stone and directly using stone curing agents, resulting in poor maintenance. In fact, it is necessary to dry the stone slabs. The reason is: the dry stone slabs can remove the water in stone gaps, and the stone curing agents can penetrate to a sufficient depth and have a deeper maintenance function. When drying the slate, it should be noted that the speed of movement of the gas gun on the slate should be well controlled. If the speed is too fast, the temperature of the gas emitted by the gas gun is not high enough for the surface of the slate to effectively remove the water in the stone void. If the gas gun moves too slowly and concentrates at a certain point, the temperature of the surface of the stone will be too high, causing the surface of the stone to swell and rupture in severe cases.

2) The stone must be warmed to 40 degrees Celsius before curing agent can be used. The reason is that the temperature is too high, the solvent evaporates too quickly, the curing agent hardens on the surface of the stone earlier, and the depth of penetration is not enough. The deep conservation effect of stone curing agent is very poor. Spot materials can penetrate into the visual range.

3) Use proper amount of curing agent. The amount of stone curing agent must be sufficient, otherwise the stone cannot absorb enough to produce maintenance effect.

4) Spread evenly with a brush, so that the stone curing agent can penetrate evenly into every point on the surface of the stone, so as to avoid localized heavy use, strong conservation, and insufficient local use, resulting in a state of invasive disease.

5) Wipe the residual curing agent with a rag to prevent the residual curing agent from hardening the surface of the stone and destroy the surface gloss of the stone.

6) The project can be carried out only after 24 hours of static maintenance. If the curing agent has not completely hardened, its curing effect will be poor, which may lead to failure of maintenance.
