How to know if your granite needs sealing
You probably won’t be able to find out if your granite flooring or kitchen counter needs sealing by just looking at it. There are simple tests which can determine this for you. One of those tests includes placing a paper towel or a cotton towel on the granite kitchen counter. If the towel becomes wet after a few minutes, then it indicates that water might be seeping into the granite.
Another test, called the solvent test, is used to determine the same. Just apply a spot of paint thinner and leave it to dry for 10 minutes. If the spot turns dark, then you probably need granite sealing to be done. Basically, if the granite turns dark after conducting these two tests, it indicates high absorption, which needs to be corrected through sealing.
Granite polishing and sealing in Phoenix
There are plenty of granite maintenance services in Phoenix that deal with granite sealing and polishing. Sealing cannot be done without polishing the granite first. Therefore, a professional service will do both. First the granite is polished using high end equipment, such as a grinder or stone polisher with diamond grit pads. These pads come with various grit sizes and the size used depends on how much polishing is needed. The more the polishing, the higher the grit size.
Granite sealing is done once the polishing is over. The type of sealant used depends on how much protection you want. For instance, a penetrative sealant is applied to ensure that the granite becomes completely non-porous. This, then prevents water or oil from permeating into the granite pores and damaging it.
