There are a variety of solutions, one of which is sealed off from air and water, it means to clog the pores of concrete sealing closure, to achieve this functionality, there are a variety of ways, such as King Fung concrete sealer is a very good one, there are other, different. Concrete sealer on the old ground has a significant role, especially King Fung concrete sealer. Concrete sealer Its principle is as follows: King Fung concrete sealer is a liquid curing agent, non-flammable, non-toxic, tasteless, for hardening concrete floor, hardened, wear-resistant, dust-proof, impervious, gloss and other functions . Concrete sealer by fully penetrate into the concrete, and wherein the chemical composition of a chemical reaction, change the structure of concrete, in three-dimensional space to form a dense integrally, such that microvoids concrete becomes small, increasing the enhanced gel structure. Therefore, the strength of the concrete floor, a substantial increase in hardness and wear resistance, can block foreign substances (oil base) erosion and weathering, permanently sealed, hardened, and dust. Epoxy floor coating thin in one to two years after construction use, may appear different degrees of crack size, while its surface repair, we should not forget the analysis of its causes and favorable conservation measures, King Fung building materials floor where you talk about the common causes of cracks. Structural cracks: a foundation is not primarily due to the force caused uneven compaction or due to uneven subsidence occurred; b manifestations: usually occurs after the force between adjacent plates, wall, pedestal, etc., cracking at There are obvious concavity; opening wider, wider at throughout the entire plate. c pre-control measures: according to design requirements and construction specifications, foundation backfill need stratification, rolling compaction (the density of greater than 0.93); add dowel between adjacent plates; pedestal preset floor spacer and disengaged. and so on. Epoxy floor coating thin crack how conservation: a timely water conservation or conservation is not in place, or has not yet reached the design strength to premature use; b mainly for cracking phenomenon, and is accompanied by surface strength decreases from. ash, foundry and other phenomena;. c should be based on concrete curing reaction, weather and other circumstances, generally 20 hours into the mold after the sprinkler maintenance, if water conservation cause premature concrete strength is not high, it is too late as the surface of the turtle back like crack; reasonable maintenance for the first three days, watering once every two hours, seven days can watering twice a day.
