Im really not a fan of sealants for concrete..Im just not convinced
they are worth it. But if you would like to seal it there are many
products out there for this. One word of caution depending on how the
aggregate was exposed (sandblasted or hosed off) the surface may
already be very slick. If it was sandblasted then you have a much more
rough surface to start with. If it was hosed then Im sure you know
that the slightest water makes it very slick...now imagine adding a
sealent to this already slick surface..guests with a few drinks in
them....a recipe for disaster. When we seal stamp work we use glass
beads (like used for sandblasting) to add some traction to the surface
but in my opinion it is still slippery. I honestly would not wory about
a stain of this nature even if it does stain the surface it can be
removed with a cleaning agent of your choice. The other draw back is
the sealant must be re-applied on a yearly basis so if you are looking
at a large area thats quite a bit of "upkeep cost"

Concrete or concrete aggregate?
As an industry term it is usually refered to as "exposed aggregate".
For example I have an exposed aggregate drive way or patio. I think
that is what you were asking right?

off if such an accident happens.

Have you sealed a concrete patio?
Concrete or concrete aggregate?
Did the sealer last well over the years?

Any idea which sealer is the best to use?

Kind regards,
