verde uba tuba 'granite' to seal or not to seal? is daily cleaner/sealer okay to use?

Answer 1

I am no expert but I have seen other sites which say that dark granite slabs are usually not sealed because it is denser than lighter colored. If is cut into squares and then set with grout, then the grout needs to be sealed.

The Oil And Lemon Juice Test
Getting Started:
(Perform this test prior to your stone purchase.)
Line your Granite samples on a table with the polished side up and then dust them thoroughly.
Spill a few drops of lemon juice and cooking oil on each one of them. Be sure to use different spots of the surface on the stone for the juice and oil.
Let the lemon juice and the oil sit on the surface of the stone for 5 minutes or so, and then wipe it dry.

Test Results:
If you notice dull spots where the lemon juice hit the surface, you do not want this Granite for your kitchen counter tops. This "Granite" is mixed with calcite or other acid sensitive minerals and maintenance will be a nightmare!
If the stone surface turns dark almost immediately, you do not want this Granite for your kitchen counter tops. This "Granite" is extremely absorbent and you will be a slave to it!
If it takes 30 seconds or a little more to turn dark, you may have a stone that can be controlled with a good quality impregnating sealer.
If it takes more than 5 minutes, you have a stone that probably doesn't even need to be sealed!
