Best concrete sealer to prevent salt damage? Any virgin concrete

growingadviceNovember 1, 2013

I'm not sure which part of the forum this question is most appropriate for, so I'll ask it here:

hi,
I'm having a concrete walkway poured in the next couple of days. I live in Western MA and am worried about ice melt damaging the concrete.
not very big, about 240sq ft.
I've read that there are sealers out there that will not allow that to happen, but everyone says theirs is the best!

Can anyone recommend some? Or what I can do to melt ice without damaging the concrete?

Of course, not putting down ice melt, is just looking for someone to get seriously hurt.

Advice would be appreciated.

Call Prosoco.

They have very good products and I think some of their densifying agents will work in your application.

There are many sealing products out there that make outrageous claims. If you are not a chemist, you are right it can be hard to tell who is telling the truth. Or worse yet, many people are quick to give advice on subjects they really aren't experts in.

  1. In order to keep salt out of your concrete you want fluids to get in. Namely water carrying salt is what penetrates and damages (breaks csa bonds) your slab.

2. You want something that will last and not have recoat every year.

3. There is one category of product that will fit your needs. A siloxane/ silane modified acrylic sealer will offer protection for about 2-3 years. Depending if the slab is stamped or just brush finish will determine the gloss level of sealer you will want. Stamped is normally high gloss to enhance color variations.

4. One other category of excellent sealers is completely silicon base. These sealers bond awesome, come in satin or high gloss, hold up under UV and protect from salt extremely well.
There are only two manufacturers that I know of because they are both patented. Adsil is one brand and Heal and Seal is the other. You can find Heal and Seal at http://www.walttools.com/heal-and-seal/

5. If you put a high gloss sealer down I would use silica sand or Tru Grip as a slip resistant additive. Otherwise the slab will be slippery without ice.

Also, do not just use a densifier to try to protect against salt damage. They are just silica or silica salts that react with portland or free lime - if it is available in the slab, to make more concrete on a micro scale. While this may make the concrete a little less permeable- salt will no doubt still get in and damage it.

Hope this helps
