IMPORTANT：
Crystallized Glass Stone is a latest building material and its application and construction method differ greatly from that of natural stone. Be careful.
1. Protection of surface protective film: The surface protective film pasted ex works can resist pollution and prevent scratching by sand grains. And it can be removed only after the completion of the project and being thoroughly cleaned.
2. cutting: The crystallized glass stone has high hardness and density with texture like jade. Therefore, following measure should be taken when cutting:
1) Give priority to stable cutting machine with brand diamond saw blade for crystallized glass stone. If unavailable, marble cutter (granite machine is not applicable)  with diamond saw blade can be applied.
2) Ensure sufficient cooling water to damage or explosive disruption to saw blade caused by overheat.
3) Always keep the saw blade forward in one way and draw it back after tiles have been removed to prevent accidental damages to the crystallized glass tone when returning.
4) Handheld electric marble saw is hard to operate and should be operated by trained and experienced workers. Ensure cooling water ejected aiming at the cutting position all the time. Cut a shallow slot first as a guiding slot for following cutting to ensure smooth cutting and avoid damages caused by swinging of the blade.
5) Due to high wearing of cutting edge, the blade should be edged timely to ensure the sharpness of the diamond cutting edge. No matter which cutter you choose, excellent edging materials should be ensured. And common refractory fireclay block is recommended.
3. Laying: Organic glues with appropriate flexibility are recommended to bind the tiles. Application of traditional slush technique in laying on the floor may cause cracks to some tiles. In view of this, improving measures are as follows:
1) It is necessary to add saw dust of proper amount to both bedding of the slush and plain cement directly pasted to the bottom of the bricks.
2) As regards the type of cement, the strength of the cement for the bedding should be lower than 400#, and better to be 350#. Plain cement should apply 275# white cement.
3) Recommended amount of addition of saw dust is respectively10-15% and 5-7% for bedding slush and plain cement and should be applied according to specified amount after on-site test for specific engineering situations. On the premise of not influencing mixing performance, the amount should be as large as possible. Add a little 107 liquid cement if necessary.
4) Brickwork joint should be washed clean before joint filling. Paste the four sides of the tile along the joints with color protective paper and then carry out operation with appropriate filler
