Update for 2023: Best Sealer for a Garage Floor
In this updated article, we talk about the Best Sealer for a Garage Floor. If you have encountered any issues and have any suggestions or have questions, please comment below.
Best Sealer for a Garage Floor to prevent oil stains and make cleanup easier.
Garage floors can be a pain to keep clean and looking good. Because garage floor concrete is porous, it easily absorbs moisture and stains such as automotive oil and coolant. Once these stains penetrate the concrete, they are hard to remove.
The best sealer for a garage floor will offer resistance to unwanted staining. The best sealer will also keep water and moisture from penetrating the concrete and causing damage. A garage floor sealer application will increase the appearance of the floor and make it easier to maintain. Unwanted fluids and stains can be cleaned up more easily on sealed concrete than concrete that is not protected.
Best Non-Gloss Sealer for Garage Floor
There are a variety of sealers offered that are user-friendly and easy to apply. A good penetrating sealer with no gloss is an excellent choice for sealing a garage floor. The non-gloss finish of a siloxane-based sealer will not give the floor a slippery texture but will lock out moisture and potential stains.
Clear siloxane-based garage floor sealers penetrate up to a ¼ inch or more into the surface and are not prone to peeling or flaking. In addition, the best sealer for a garage floor will contain a blend of silanes and siloxanes to create a salt barrier. This barrier gives greater protection from the deteriorating effects of salts and de-icing chemicals.
Best Penetrating Garage Floor Sealers
These are excellent garage floor sealers that are 100% breathable and provide and non-slip, no gloss finish that will keep your garage floor damage-free and protect against stains and spills.
Best Glossy Sealer for Garage Floor

Our home sets on land with a high water table. When it rains enough water comes up through the concrete garage floor. Our home is 46 years old. Will using Super Seal-M Water Repellent or Masonry Saver Heavy Duty Water Repellent (Defy) help resolve this problem? If not, is there anything else we can do? The previous owner never had a sump pump installed in the crawl space and that is on our to do list. The house inspector didn’t check out the crawl space because there was 7 or 8 inches of water in the crawl space at the… Read more »
No sealer can stop water from seeping or leaching out of concrete. They only work by preventing water from soaking into concrete.

The paint on my garage floor is coming off in patches and the concrete below is very dusty. I would like to seal it first to cure the dust problem then repaint it. Recommendations please.
That will not work. You cannot seal over a paint to control dust and you cannot apply paint over a sealer as the paint will not adhere. The only way to fix correctly is to grind off the paint: https://www.concretesealerreview.com/how-to-remove-an-epoxy-coating/
Then apply a 100% Epoxy Coating system like this: https://www.concretesealerreview.com/restore-a-garage-epoxy-coating-review/
I have a 12 year old garage floor that is in good condition. The floor has oil stains, hot tire marks, and some black paint marks on the floor. I have tried everything to clean these areas and nothing works. I live in Florida and what sealer should I use on my garage floor. Should I wash the floor with a solution of muricacid before sealing?

Have you considered and Epoxy Coating? https://www.concretesealerreview.com/what-is-the-best-epoxy-floor-coating-reviews/
How to prep will determine the type of sealer or coating you choose. Have you true a concrete cleaner and degrease?
Does it matter that the concrete has a burnt finish??
I do not think it would.
had my garage floor painted with epoxy and flakes and getting tire marks I cleaned the best I can what sealer can I use to prvent this from happening again
You cannot apply a concrete sealer over an epoxy floor coating.
Can you paint over Clear siloxane-based garage floor sealers?, thanks
Probaly not. It will repel the paint for adhering.
Does a penetrating sealing make the concrete floor easier to sweep? I mean, so cement dust doesn't keep sweeping up indefinitely?
Would a concrete admixture such as BASF MasterLife 300D provide the same protection against staining as a Siloxane Sealant?
Sorry but no idea on this one.
