I was wondering if I really need to seal my garage floor? If I don't seal it will it get destroyed. I dont' want to do any permanent damage. I don't really care about the looks though. I put the garage up to be functional. I really just want to get everything moved into it.
It keeps the dust down, unsealed concrete will always create dust.
If your using it strictly for shop I'd seal it. If your using it for a bit of shop use and everyday car use, get a sealer with grit in it so you don't fall on your *** when it's wet. It's worse than a slip 'n slide.
I epoxy sealed mine and added the fine grit (both available at Lowe's Home Centers and Home Depot). I've spilled oil, gas, etc on it and it still looks good. If you live where they put salt on the roads in the winter, I would recommend the epoxy sealer. I think you have to wait, like 1 or 2 months, on new floors for the concrete to fully cure and for the floor/ambient air to be above a certain temp.
if your going to have autos in there that drip winter road spray seal it. the salts will eat the top off the concrete surface, then you have a very difficult problem to fix.
Spalling(salt holes) in the concrete can be a problem. But it really isn't that big of a deal to fix. You just have to shop at a contractor supplier rather than a Home Despot-type of place.
Get a high quality sealer intended for garage floors. A high-end sealer like Dayton Superior J-35 Tuf Sealer is intended for exactly the use you are talking about. It originally was formulated for Auto Plants and Dealership Service Depts. Another good one is Conspec Crystal Seal(IRC almost the same thing) Burke-Edoco calls theirs the same thing (Crystal Seal). They are both made by the same people.
White Cap Industries sells all three of these sealers, and they are owned by the Home Despot now. So coming to a neighborhood near you.
Do they make something to fill/hide the cracks, before you epoxy the floor?
Yes, there are several kinds of crack fillers out there. For most users you can get a good product from your local hardware or lumberyard. I have to admit that I personally am very-anti HD, or Lowe's. I much prefer a local person or a contractor supply type of establishment.
Be aware though that different crack fillers have different resistance to freeze-thaw cycles. Make sure to get one appropriate to your local climate and usage. Also make sure that the product is outdoor use specified if you are using it for that. There is a line of crack fillers out that is re-emulsifiable. That means that it will turn back into a liquid when exposed to water.
