Broom Finish Concrete Sealing Advice

Finished Concrete Front Door Steps, Sidewalk to the back and patio in plain broom finish. Around 800 Sq. Ft

The contractor recommended sealing to avoid soil and oil stains and salt damage or make sure we use Blue Salt.
To seal, I am getting quotes for different brand names including Seal King, Natraseal, Kimbol. I am looking for a semi-gloss look.

First of all, does broom finish require sealing? Also, is there any website or place where all these sealant comparisons are available? or a brand that you would recommend?

Strange. I had broom finished concrete done by Pro Concrete a couple of years back. They recommended not to seal. Unfortunately can’t recall what their justification was. But I don’t use ant kind of winter salt.

Well, one reason not to seal seal is to avoid it becoming slippery in the wet.
But you can DIY apply siloxane.

Don't do this. Siloxanes are toxic, persistent, and have the potential to bioaccumulate in aquatic organisms.

So no sealing and keeping it natural then? Does salt clung to the shoes damage the concrete?

If not sealing, then I would think that densifier would strengthen and prevent salt damage, but I'm not sure about that.

Salt damages everything. I would keep it shoveled with plastic shovel (no de-icing salts or chemicals), sweep with stiff brush broom after shoveling if you want and don't let your car drop those brown chunks onto it (and if they fall off, remove them ASAP).

I can't imagine sealing a brushed concrete. Sure it will offer some protection, but it's going to be slick in the winter.

Back in the 90's we had a brushed concrete driveway done and decided to seal it. It looked great (kind of a pearl finish) until after the first winter. With the constant pulling in and out of the driveway with salt/winter crud on our tires the area where the tires came into contact with the sealed finish it wore it down so it looked different from the rest of the beautiful pearl finish.

We tried power washing/degreasing the driveway then resealing the entire thing but the resealing actually highlighted the area where the tires went and always had a different look to it than the rest.

This was back in the days of the Xylene based sealers which are super strong and durable. The sealers of today are nowhere near as durable.

One thing to note was that our walkways we also sealed and they maintained a perfect pearl finish for as long as we were in the house which was about 12 years.

So I'd definite no to sealing the driveway but with option to seal the walkways if you like.
