Microcrystalline stone construction notes: (It is not recommended to lay the product on the ground in public places.)
Surface protection: The surface protection film that has been posted is not only prevented from contamination but also prevented from scratching the sand grains. Whether dry hanging or sticking, must adhere to the completion of the work and thoroughly cleaned before removing the protective film. If the brick surface does not have this protective film, it should be covered with a protective layer on the brick surface, such as cardboard or thin wood.
Cutting: The microcrystalline surface layer is both high in hardness and extremely dense. The texture is very similar to that of jade. When cutting, it is necessary to prevent collapse. For this reason, the following measures should be taken in cutting:
1 Give priority to the use of a stable desktop sawing machine. Selected brand-name crystal glass special diamond saw blade. No marble saw blades (not granite) were used. 2 Ensure sufficient cooling water to avoid overheating causing bursts or even rapid damage to the blade. 3 Always keep the saw blade one way forward, after cutting,
The tiles are removed first, and then the saw blade can be pulled backwards to prevent the blade from accidentally scratching during the return stroke and causing chipping defects. 4 If you use a portable electric marble saw, because it is difficult to operate, it must be arranged by experienced skilled workers to ensure that the injected cooling water flow is always aligned with the moving cutting point. And first
A shallow groove is cut out as a guide groove for subsequent deep cuts, so as to ensure that the saw blade always moves forward smoothly without causing collapse and damage caused by left and right swings. 5 In the case of sharp edge consumption, care must be taken to sharpen the edge in time. Always keep the cutting edge of diamonds sharp. No matter what kind of sawing machine, you should use good edged materials.
First use ordinary clay firebricks.
Waterproof: Apply waterproof lacquer to the four sides of the tile, and apply a 2 cm wide waterproof lacquer layer around the bottom of the tile. Only after the above waterproof coating is dry, do it work.
Paving: Advocate the use of organic rubber tiles with appropriate elasticity. The use of a traditional cement mortar process on the ground is often prone to cracking of some of the tiles. The improvement measures for this issue are:
1 Pay attention to the size and color number marked on the package, and use them separately. When laying a tile, reserve 2-3mm mortar between brick and brick. 2 Both the cement mortar bed and the pure cement "primary ash" applied directly to the bottom surface of the bricks need to be mixed with suitable sawdust (wood filing). 3 Regarding the cement type, the ordinary cement of the bed should not exceed 400#, 350#
better. Pure "prime gray" should use 275# white cement. 4 The recommended weight mixing ratio of sawdust is 10 to 15% for cement mortar in the foundation bed and 5 to 7% for “primary ash”. However, the applicable value under the specific conditions of the project should be determined after on-site testing. Inhibit the mixing performance under the premise that the incorporation ratio should be as large as possible, if needed
Appropriate to add a small amount of building 107 glue. 5 Caulking operations should first clean the brick joints. Then the four edges of the tile are attached to the separation paper to protect it. Only then use proper caulking agent for caulking. The construction process also needs to pay attention to the refinement of the process. In order to maintain the overall surface flatness, the seam piece fits. Ground-mounted products in public places should be periodically maintained (similar to stone maintenance).
