TL;DR Summary: This worked for me. The rain drops beaded up and wicks down my concrete driveway.

First time homeowner here. I'm learning a lot about home care/maintenance from my neighbors & internet. Recently, neighbors brought up benefits of sealing the concrete driveways. This is to prolong and protect the concrete from winter conditions (freeze/thaw, road salt). If you live in an area without harsh winters…I don't know if there is much benefit in sealing your concrete surfaces.

There are a number of options for sealers (different chemistries) – since this is my first time sealing, I can't comment on the pros & cons of other sealers. I choose this brand because the active chemicals (silane/siloxane functional group) is relatively benign for humans/pets/lawn.

I got the larger (32 oz. concentrate) which is rated to cover 1000 ft. It is a low-viscosity (thin) white liquid concentrate that you mix with water. I used a pump sprayer to apply it.

Per directions, I power/pressure washed my driveway. Allowed ~24 hours to dry (important: concrete must be dry before you apply sealer!!!).

Knowing how much to spray-on is kind of an art. Per directions, I sprayed the first coat, waited for it to (mostly) dry, then applied second coat. Started at the top of my driveway. By the time I reach the bottom of the driveway, next to the curb (during the second coat), I ran out of sealer. I thought, "oh well, at least I got one coat next to the curb…". After a few days, it rained. My driveway areas that got 2-coats, are wicking off the water (like rain drops off a duck's back). The droplets run down my driveway and (surprisingly) filling up and pooling in my horizontal control joints. Not necessarily a bad thing, since it is visual evidence that this sealer is doing its job (I'm just surprised that its even preventing water from going down into the pretty sizable cracks of the control joint).

However, the curb area that only got 1-coat does not look like it had any sealer. Moral of the story: per directions, ALWAYS put down 2-coats for the best results.

Time will tell as to how long this sealer lasts…..

After you apply this , will the driveway feel slicky due to coating n not safe to walk especially during the winter?

I just put down 2 coats last week. It doesn't make the concrete slippery at all even when wet.

Another good thing to do is is to fill your relief cuts with self leveling caulk. Water will keep getting under your concrete that way and with the freeze and thaw effect will eventually cause quite a bit of damage. After having a house with a horrible driveway I did the concrete seal and the caulking before our first winter in our new house.

Thanks for the heads up!

I'm on the fence on if the weather will allow for me to fill the control or expansion joints.

Also, I'm not sure if the joint sealer will stick, now that I've put down this Rain Guard.

I'll try to report back on this post if I end up sealing the joints.

I sealed the concrete before filling my joints. 3 years later and I haven't lost an inch of the caulking. It's definitely worth the time and money.

Appreciate the info! Any recommendations on the joint sealer? I've used Sikaflex brand in the past, but would like to hear your thoughts.

That's what I used, the self leveling Sika. My only complaint is that it's lighter than my actual concrete in color. But after one season it's not noticeable until you power wash the driveway. Then it gets dirty again and it's not noticeable.

I don't know if this brand makes it but search asphalt sealer. A lot of improvements stores sell it in 5 gal buckets. I just resealed my driveway.
