[Instructions]
1.Surface treatment
The block surface should be clean, no mud, sand and oil or other impurities;
Remove the big defects on the block surface such as the soil;
Polish the sharp edges or corners on the blocks.
2.Prepare the glue and mix
Mix the glue in A:B=1:1(by weight)and stir completely with the electric mixer, do not mix the apparatus of A and B. Do not pour the mixed glue back to the package;
Please use up the glue within the pot life. The glue will be fever and is prohibited to use when beyond the pot life. Under 25~30℃, the mixed glue 3kg should be used up within 10 mins. The more of the glue mixed, and the higher of the temperature, the pot life is shorter.
Do not mix the cap of A and B. Please seal the caps anytime in case the moisture and dash from the air.
If temperature is very low, the glue will be thicker, heat up the glue in water bath to decrease the viscosity for a convenient use.
3.Spreading the glue
The perfect temperature to spread the glue is 25-35℃, air humidity less than 75%;
Scrape the glue back and forth, spread the glue evenly on the surface of the block;
Wrap the block with the fiberglass mesh flatly and overlap should be more than 10cm;
Press the fiberglass mesh to be block with the scrape, then spread the glue again on the fiberglass mesh.
4.Glue solidify
Initial curing of the glue is in 2-3 hours at room temperature and can be proceed to next procedure after 24 hours;
The operation temperature should not be lower than 5℃, when the temperature lower than 10℃, the curing speed will be slow down, we suggest to heat up to accelerate the curing speed.
5.Clean up
Please clean the apparatus with professional cleaner before the glue cured.

[Protection measures]
For different workers, the glue may irritate the skin, but the product meet national standard GB18583-200, it is environmental friendly and no harm to human body.
When using this glue, please take the protections as below:
Use the glue in the ventilate environment
Wear the protection cloths, gloves and mask
In case the glue contact skin directly, if any, clean with the soap water
Before mix the glue, open the cap of Part B first, wait for the volatility of the free low molecular materials
If any irritation to the skin, better to change to other jobs.

[Notes]
1.Some facts will affect the performance of the glue as below:
The stone is not dry enough or the air humidity is too high, the stone absorbed the moisture from air
Part A and B was not mixed exactly base on the stipulated ratio
Glue mix uneven or not completely 
The mixed glue was not used within the pot life.
2.In winter and low temperature, the product may form crystal or caking. Just heat up the glue and make the crystal or caking dissolved, this will not affect the glue performance.
3.Clean and wipe the glue on cloth or skin before it cured with alcohol, then flush with soap water. If in eyes, flush with plenty of water and seek for medical cure; if swallowed, do not emetic, drink plenty of egg white or milk, then seek for medical cure immediately. 

[Stock and package]
1.Sealed and stock in cool, dry and ventilate place, stock temperature under 5-40℃. Shelf life one year from the production date, it can be still used based on passing the test when beyond the shelf life. 
2.This product is corrosive goods, keep far away from the heat, fire, sunshine and rain during delivery and stock. In the process of transportation, operate gently, it is prohibited to roll, impact, stress, inversion, and offset
3.Packing size: 60kg/set,packed in plastic drum.

[Important notes]
1.For materials to be bond are different, this may affect the glue performance. Please have a try before plenty use.
2.We solemn promise: we produce the products according to our enterprise standard strictly, we will responsible for the product quality, but not responsible for the operation process.
