Concrete Sealer

[mark2457]

Hi Guys

My slab is being poured today and the concrete guy said I should seal it to prevent salt water from car in winter staining it. Any recommendations for a good sealer. Ideally, something that can be picked up at a local Menards/HD/Lowes.

Regards
Mark

I have seen a lot of contractors spray on the sealer just after laying down the last trowel job. I don't know whether putting it on while the concrete is green or waiting until it is is cured ...is best. No one has proved to me either method is better.

Siloxane is what I used on my drive and all the commercial drives/brick chimneys at work for the passed 15 years. Each to their own though. JMO ....

It was pouring rain in the pic below of my probably 5 y.o. drive and had been raining for an hour. I put siloxane sealer on it two weeks prior and only had enough to do the white shaded areas of the concrete. Which shows to me at least, the water was not penetrating the concrete in the sealed areas.

Yes, there are several different types of sealers and it depends on what you want to protect it from. We offer TL39 which is a densifier and silane / siloxane sealer but we do not sell through box stores.

If you go to home depot website and search http://www.homedepot.com/s/silane?NCNI-5 ypu should be able to narrow it down based on what is stocked in your area

Generally when a mason pours a slab and then sprays something on it, it is a curing compound to help slow the evaporation of moisture out of the slab. A slow cure helps promote strength in the concrete. In summer months when concrete dries out on the top surface really fast the slab edges can actually curl upwards. By spraying a film forming curing compound the water in the concrete mix slowly evaporates and will tend to cure evenly. They make just curing compounds, just sealers for application after the slabs have cured and combination sealer/curing compounds. Most folks on this site talk about wanting to apply a sealer well after their concrete slab has cured. There are tons of different sealers on the market.... I highly recommend finding a local construction materials or mason supply house to get your selected sealer and/or curing compound. There are several makers to choose from. BUT these places will help you make a choice and offer a couple options. Folks on this site are all like minded and want to understand why, what, how and $$....these supply houses can do that also, they are there to help.

How long after the concrete is poured do I have to wait to apply it?
