If you don’t seal a concrete patio, the surface may crack, fade, or stain. While it’s not strictly necessary to seal a concrete patio, doing so can help protect it, extend its lifespan, and enhance its beauty.

Whether or not you need reinforcements for your concrete slab depends on the thickness, what you’ll use the slab for, and the climate and soil conditions in your area. Adding reinforcements increases the strength and durability of your concrete slab, so it’s ideal for load-bearing slabs like driveways and home foundations. It can also help reduce the risk of cracking in extreme climates and areas that see excessive soil movement. Speak with your professional to determine if your project requires reinforcement.

Yes, you can seal an old concrete floor as long as you remove stains and repair damage before sealing. Remove everything from the garage and clear the floor throughout with a concrete cleaner and power washing. Fill in cracks larger than 1/8 of an inch wide and remove all grease and rust stains before sealing. Make sure your concrete is fully dried before applying sealer.

Dry pour concrete cures in the same amount of time as wet pour concrete, so you’re looking at four to six hours for it to harden, 24 to 48 hours before you can remove forms and expose the slab to foot traffic, a week before it can stand up to vehicle traffic, and about a month for it to be fully cured.
