Santa Cecilia Stone countertop/backsplash

We have Santa Cecilia (polished) countertops and backsplash with an accent of Black Galaxy (polished) behind the cooktop. What is/are the best product(s) to seal these stone surfaces and how many coats of product should be applied? Thanks for your input. Mark

 

Dear Mark:

The Black Galaxy accent can't be sealed. (The stone won't absorb the impregnator, a.k.a. sealer).

For the rest, you have first to find out if your stone can actually take any impregnator in.

Santa Cecilia does need to be sealed with a good-quality stone impregnator in its natural state, but (very good) chances are that your slab had been resined from the factory. If that's the case, the resining process may have already taken care of the sealing in a permanent way.

How to find out if your countertop can be sealed?

Do this:

Spill some water in a couple of spots of your countertop, let it dwell for 5 minutes or so, wipe it dry and observe if the areas under which the water has been sitting have become (temporarily) any darker than the rest. If so, then you will apply a good-quality impregnating sealer like MB-4. If not, don't.

 

Most important of all…

Remember: it's never too early to think about the proper maintenance of your stone. The issue of what you'll be doing day in and day out to your stone is far more important than the sealing itself and it's all too often neglected.
