Problems You May Encounter With Granite

By Anita Ortega


Granite is one of the most used rock in industrial and commercial construction together with marble and other types of rocks. It is an igneous combined with quartz and feldspars and other mono rocks. Granite tampa florida mostly appears as a dark or light grey stone and mostly used as tiles, grave markers, sculpture and stone tables.

But there are some issues regarding its quality over time. These qualitative problems can be its natural reaction or its reaction towards some other thing. But this problems can be avoided if they are being managed accordingly. And this is why you need to know its issues for you to be prepared or find a way to avoid them.

The very first one is that this type of rock blisters, if being exposed to the water for a very long time, it will swell. This is a natural phenomenon of such stone which can be minimized using some lamination chemicals available in hardware stores. So if you think that exposure to water is part of the work, then this is not the ideal stone.

Chipping and cracking is another thing which can be very damaging especially if you are doing a sculpture. The former is a separation of some small pieces to the larger pieces of masonry. So if you are hitting it too hard, it could easily chip. This is somehow connected to cracking which can also occur if someone is doing it too hard.

Another thing is that it creates white substances that will appear like the north and south poles of the map. This is its efflorescence reaction which is usually caused of wrong usage of cleaning agents or using the wrong chemical for any purpose. This is not ideal considering that you will use it for aesthetic purposes.

If granite is left uncovered and it is always exposed in air or placed outdoor, surely its surface will erode. This case can be compared to the case of the great sphinx of Egypt in which you can see some deep lines on it which was once thought to be cause by water but then it is caused by air. This is because granite is not made of only one substance but different types.

Flaking and Peeling, flaking mostly cause by thawing and freezing cycles which can cause water exposure to its surface. The exfoliation and delamination is more affective than those in blistering. The latter is the process of flaking away of the surface of the rock. Usually comes out into thin strips which usually caused by improper masonry such as putting chemical covers.

Another problem is vandalism and bird waste stains. Yes, even if they are not caused by the stone, its reaction is a big problem because once the act is already done it can no longer be undone not unless you will sacrifice the surface affected.If the stain is already on it, it can no longer be removed without damaging it unlike glasses which you can still find a way. Those iron connectors can also cause for its staining. So whenever you will use something, be sure that it will not cause it to damage its real appearance.
