When repairing cracks and other damage to your concrete you have two basic options: epoxy-based repair kits and polymerized concrete. Both of these solutions work well but please realize that neither of these will match the color of your current garage floor. If you are concerned about appearance you will need to paint, cover or resurface the floor after you repair it. There are a vast number of professional grade products out there that require a lot more knowledge and experience than the average person possesses.
One professional brand has almost a dozen concrete mixes alone all for different purposes. This article is focused mainly on consumer level advice. Just a quick interruption to ask you: are you sure you want to epoxy that floor? Just be aware of the prep work involved before starting.
A word of caution: as epoxy cures to a hard material, it gives off heat. If you mixed a pint of epoxy in a container and left it the temperature could get up to deg. It also binds to skin quite well and can give you a nasty burn. Do not perform this kind of repair without wearing protective gear. Epoxy has two components, a resin and a hardener. These components are mixed, either in a self mixing nozzle or on a piece of cardboard or other disposable surface.
The mixture then cures into a hard, sand-able and paintable material. Unlike concrete epoxy is not porous and resists oils and road salts. It can be mixed with aggregate material dehydrated sand and other materials to give it a more concrete-like appearance. Also note that the product may become difficult to work with before it is fully cured. Polymerized concrete is cement mixed with special aggregate material that allows it to adhere to existing concrete. Just like epoxy, concrete hardens by a curing process.
Hydration is an active reaction that gives off a lot of heat. So much so that when they built the Hoover Dam they needed to install a network of cooling pipes to facilitate the curing process.
Polymerized concrete comes in powder form that you mix with water. It takes longer to cure than epoxy giving you more time to work and giving you a chance to mix enough for a larger area. Follow the instructions and use the proper ratio for best results.

For concrete spalling, the damage occurs on a microscopic level. The water freezes and subsequently expands into its surroundings, causing the surface to weaken, separate, and finally crumble.
This depends on how big the size of the repair is, how deep it is, and sometimes, how you wanna look at it. Even for the most novice DIY users, we can confidently say that following our guide will make you repair that concrete garage floor entrance in no time! So, the first thing to do to prepare the concrete is to clean.

Heard a hollow sound? For one-day garage floors, call us at The 2 young guys that did my floor did an outstanding job. They were on time and worked almost non stop for 6 hours. They explained every step of the process and were very knowledgeable. The floor exceeds my expectation.
I highly recommend Guardian. I did a lot of research The entire team at Guardian Garage Floors was great to work with from start to finish. The area manager Jeremy Lundy was extremely knowledgeable and follow up was great throughout the entire process.
Moving to a new home is never an easy task, but Guardian made at least a portion of it better. They accommodated several last-minute schedule changes graciously and completed the application in less than a whole day. Incredible transformation!!
