Concrete Resurfacing - No More Ugly Concrete
When it comes to resurfacing your concrete floors, the first thing you have to make sure of, is that you can actually get the surface prepped to properly adhere a new coating. Think about this, 90% of all failures when resurfacing concrete, has to do with bad surface preparation for product adhesion. So you need to make sure your surface is super clean and dust free. A pressure washer of at least 3,000 PSI and uses 4 gallons per minute is recommended by most companies. But remember, a little bit of dust and dirt can cause the product to fail/not adhere to the concrete substructure.
This really is not a do it yourself project, you'll need to work with hand trowel tools, and be able to spend extended time on your hands and knees. Most do it yourselfers might attempt this job, and when they're done, most of them will tell you their horror story, and talk of the money and time they wasted. We suggest you spare yourself the frustration and talk to an expert before taking on such a project, this is not a simple project; even though the companies selling over the counter products make it look simple.
So here's the basics for what's involved. First as mentioned earlier, you need a clean surface; and that means the removal of all dirt, loose rocks, oil stains and any other substances that have made their way onto the top of your concrete's surface. Then we need to address any cracks/crack lines in the substructure.
Most of the cracks will be V grinded, taking that simple crack and turning it into a V or valley to prep for the next step which is filling in the crack. When the cracks are filled in and the product hardens, then the excess crack filler is removed and smoothed out to match the rest of the floor.
At this point it is typical to add a bonding agent to the surface that will help with the adhesion of the resurfacing material. This is where you'll need to throw on your knee pads and be careful not to paint yourself into a corner. The product is slowly spread evenly over the surface with a trowel and then given time to properly cure before using, aprox 48-72 hours.
It's a really good idea to talk with a contractor before even exploring the idea of resurfacing your concrete. They can tell you what to expect, and if your slab is a good candidate for concrete resurfacing. Remember, some slabs are not good candidates for resurfacing, and that can take years of experience to see the warning signs. You're your local concrete polishing contractor, they'll be happy to answer your questions and help you to get the results you want. You don't have to live with that ugly concrete floor.
