The correct selection of protective agent:
     The stone protective agent, consideration should be given to the surface type of stone, stone, the
requirements on the stone decorative effect and climateMany environmental factors such as selection of
specific products and construction scheme. In addition, it is the most serious, no matter what the protective
agent,Large area before the construction, should be the first to do local scale, prevent accidents due to ill
considered and. Specific selection method can be simply summarized as follows:
     1, water repellant not alkali resistant, recommended for dry hanging stone, dry hanging stone to the
general water repellant six maintenance. Water absorptionThe stone surface of the smaller (especially
black, cyan stone) should use oily protectant etc..Granite stone
     2, installation of the wet paste, the front must choose strong permeable protective agent, it can pene
trate into the depth of 5-8mm, stone, andPart formed strong resistance to the hydrophobic layer, effective
organization supratidal infiltration, and keep the water discharge, so as to effectively prevent the formation
of water spot.Stone as the characteristics of strong absorbent
     3, strong water absorption, recommend the use of specific products sandstone protective agent, to
achieve more satisfactory waterproof,Antifouling effect. Water soluble products can be used in sandstone,
but antifouling effect is unsatisfactory.
     4, the marble is a kind of CaCO3 as the main component of the stone material, different from siliceous
granite, generally relatively soft texture (there are a fewThe number of hard dense varieties) and contains
many small cracks. The processing technology and also polished granite surface of different, add the resin
A, it should use the products marble protective agent, dry suspending construction water repellant or oily
protective agent for six surface protection, wet pasteDuring the construction, especially the more varieties,
cracks often appear seepage phenomenon, with the bottom end of the interface agent to seal protection,
to achieve the mostBetter effect.
     5, the environmental temperature is too low, water repellant likely due to icing and can not work, then
should use oily protective agent. But it should be appropriately extendedThe maintenance period to make
the active ingredients fully fixed, suitable for the construction of the environment temperature is
10 ℃ -40 ℃, relative humidity 50%-80%.
