a good coating

[qizhenapp]

<p>The purpose of the coating is to cover up the cover, do a good coating can be almost real ones. For example, the use of imitation stone paint on the external walls, we have made the use of cutting saw stone waste made of imitation fire board and wool board coating: for indoor ground, for example, some of the more serious erosion, holes, cracks or loose stone , Can be used to fill the pores and cracks with resin filler, and then use the stone enhancer penetration reinforcement, and then grinding and polishing. We produce stone reinforcements commonly used in stone renovation works. In addition, some bright resin is also commonly used in indoor stone surface of the light or light treatment, can achieve the effect of improving the quality of stone. </p><p>For some difficult to clean the way to remove the shallow stains, such as organic stains, salt and white, water and water spots, grinding and sandblasting method is also effective, but the cost is higher. Second, cleaning and renovation after the protection After cleaning and refurbishment, the micropores of the stone have been opened, increasing the specific surface area, so that the adsorption capacity of dust and sewage increased, if not timely for the treatment is easy to be contaminated again.</p><p> For the stone surface protective agent we have a lot of discussion, here only to mention a few basic to have a better protection, that is able to alleviate or block the surrounding environment erosion, destruction and defacement, such as acid rain, anti-pollution, Alkali cleaning, hydrophobic oil repellent, etc .; protective agent and stone should have a good compatibility, that is, the protective agent itself and its role in the process can not have a negative effect on the stone, such as yellowing, resulting in expansion of pressure, The protective agent should have good weather resistance and recoatability because the normal life span of the stone is much longer than that of the ordinary organic protective agent. The better the weatherability of the protective agent, the less the number of recoat, the better the recoatability. The smaller the negative impact on the stone after failure. Generally speaking, the use of respiratory function of the penetration of silicone protective agent is better.</p>
