British ground brown polished stone renovation before the first pointing and waterproof, do caulk aimed Shi Dao Tan Brown Granite water as little as possible, to reduce the UK brown granite water law, under conditions permitting, the last to do it again waterproof .
Roughing: Tan Brown Granite before grinding to do the waterproof groove joints and caulk. Be waterproof effect out, the use of a hard resin diamond grinding blocks, rough grinding to remember that not too much water, each grinding mill finished dragging a clean mop, thoroughly dry the water, leaving a deep examination grinding notches plan whether to use channel 50 # grinding worn away, and so, tic-tac-go machine grinding, polishing coarse grinding representing 45% of the overall time is to ensure the quality of project completion and acceptance of the key links.
Fine grinding: grinding to do before waterproof, waterproof effect after it, use a soft diamond resin sheet mill, finely ground 35% of overall research time, finely ground to a 2000 # gloss after up to 50 degrees.

UK Brown Physical properties: a bulk density of 2.97g / cm3, compression resistance 122.6Mpa, bending resistance 17.4Mpa, water absorption 0.19%, Mohs hardness of 6.6, 86.6 gloss
Layout features: reddish brown, luminosity good, so different lines for different blocks of a material, there are no results, open face: large patterns, from the side of the opening: Small pattern
The main advantages and disadvantages: This variety is mainly brown-red bottom enjoyed like structure, according to the different colors is divided into dark red, pink, flower, flowers, etc. The species is relatively stable, the same mine its color, crystal, patterns, such as a slight change, the main defect black bile, black, red bars, uneven lines, flower uneven crack.
