Steps for usage
1. The plate is heated or ventilated to remove moisture;
2. Use a brush or a rag to remove dust, scum and other impurities from the surface of the stone;
3. Evenly spread the glass fiber mesh on the surface of the stone slab;
4. Mix the rubber in a ratio of A:B=2:1 (weight ratio) and mix well;
5. Pour the glue to the surface of the stone, scrape the glue with a squeegee knife, and apply the glue evenly on the surface of the stone, so that the glass fiber mesh is completely wetted by the glue and pasted on the surface of the stone slab;
6. under normal temperature conditions, generally should be in the next step after the adhesive layer is cured for 24 hours;
Precautions
First, when dispensing glue:
1. The proportion of glue adjustment must be accurate, and the glue must be mixed evenly;
2. Do not mix the glues of components A and B. Do not put the remaining glue after mixing back into the original packaging;
3. the glue should be used now, after the glue must be used up within the available time;
4. If the glue that exceeds the usable time has a fever, it should be stopped.
5. If the temperature is 25~30 °C, 600g of glue must be used within 5 minutes;
6. The more the amount of glue is adjusted, the higher the temperature, the shorter the time that can be used, and the longer the time is;
7. If the amount of one-time adjustment is too large, it should be used separately and quickly;
8. Do not cover the cover of components A and B. Please cover the cover at any time to avoid absorbing moisture from the air and falling into dust.
9. It is recommended to use a flatware to adjust the glue. When the temperature is high, it is better to use a cooling method to adjust the glue, which can extend the use time;
10. According to the actual situation, an appropriate amount of stone powder can be added to the glue.
Second, when scraping glue:
1. If the conditions permit, the stone can be heated to 40-50 ° C and then glued. Generally, the reference amount of the glue is 100-200 g/m2.
2. stone surface treatment agent, non-epoxy adhesives and other chemicals should not be applied or infiltrated into the stone bonding surface, otherwise it is not suitable for recoating the surface glue.
3. the stone surface has major defects, such as the soil layer should be removed first, and then take the glue and the right amount of stone powder to mix and repair the defects, after the glue is cured, then brush the rubber back mesh.
Third, when curing:
1. If the conditions permit, the glued sheet can be heated to 40-50 ° C, and after 2-3 hours, it can enter the next process;
2. Before the glue is cured, the plate should be placed in a flat position and cannot be stacked. After initial curing, a lubricant such as talc may be applied to the surface of the plate so that the plates are not bonded together when stacked.
