There appears to be based my own personal experience that theres plenty of confusion amongst some contractors and the public as to what closing normal rock actually means. When we discuss closing a surface we generally imply that an impenetrable barrier is painted on or used in some way. For example tiled floors in many cases are covered to make them shine and give them additional security. To do this a number of applications of emulsion polish are applied to the top and allowed to dry. This gives security to it and seals the ground. Other areas such as wood are often closed with a coating of a memory item. This adds strength to the top and protects it. A number of other normally porous materials may be sealed with a layer that sits on top acting as a obstacle to penetrative agents and gives protection also. The closing of natural rock including granite, marble, limestone and slate is very different. In the event people hate to learn further about Pondering of migrating to Australia?

The nutrients which can be present as crystals in-the rock give it its color and striations. But there are spaces between the crystal and the smaller these spaces are and the more the crystals have been compressed together the less porous the rock is. Therefore these spaces will determine the porosity of the rock. A combination of pore size and mineral content of the rock will also establish its longevity its hardness and hence. These areas in-the stone are air filled if the stone is dry and water filled when the stone is damp. These spaces are inhabited by bacteria and these tend to be crucial for the preservation of the stone. Almost no re-search has been completed in-to these bacteria but whats been done indicate they are important in maintaining the integrity of the stone. Therefore we have the picture of stone as a significant complex mixture of vitamins, bacteria and rooms. You must imagine the rock to be something akin to a really hard sponge! Should you drop a fluid onto the stone itll be absorbed and spread through the areas. That is why what initially appeared to be a small spillage may end up as a significant large spot within the rock. To eliminate the stain its to be flushed from these spots. All a stone sealer does it refill these rooms. Most of the stone sealants in use are derived from essential fatty acids rather than manufactured sealants. These natural sealants are better because they do not destroy the bacteria but usually increase them. Artificial sealants may eliminate these bacteria thats longer-term consequences on the rocks makeup. Sealants according to fat however possess a shorter life and should be renewed occasionally. What-ever sealant is employed it simply fills up the spaces between the crystals it does not protect the area of the rock. Its function is merely to delay the penetration of liquids into the rock. Therefore if harsh materials get onto the stone then it will be destroyed. Stone sealants dont form a protective seal on the floor of the stone. Therefore stone is only protected from absorbing beverages. Its maybe not protected from surface damage..Cam Well Paving, Melbourne, 1300 732 703
