Will this still allow efflorescence to come up in pavers? I don't want to trap efflorescence in the stones, but I want to protect them immediately.

This product appears to meet its description, it's absorbed into to brick & nothing appears to go in or come out. It seals well. I've had it on the walls for one year. You're welcome.

Beyond sealing does LastiSeal bring out the color of my concrete pavers? Gloss??

Very little gloss. I don't know if it will bring out the color of your pavers as I just on the concrete garage floor and driveway.

does it have a gloss finish

No. The intention of the sealer is penetrate into porous building materials (hence the word porous) without changing the look or friction of the surface.

Will this product turn white/cloudy when exposed to water?

Not at all. It's a milky color in the bottle but it doesn't turn anything white that I applied it to. What I did notice was the mortar between the bricks feels differently when I run my finger across it. Little grains that used to rub off before don't now. And the water seems to run right off
