Per pound, concrete is an inexpensive building product that can be easily installed, so when you have an aging or crumbling concrete installation around your home, you may be tempted to remove it and start from scratch. But when you factor in the time, effort, and disposal fees required to remove an old installation before you start anew, you're talking a major renovation project that gets costly fast.
Instead of starting over, you should consider restoring your old concrete. Restoring your old concrete installation to its glory will not only improve it for utility purposes, but it will improve the curb appeal of your home as well. So if you're ready to make changes to your concrete that matter, there are a few things you need to do to make the old look just like new.
Before you do anything major to your concrete, you need to make repairs and remove stains. Repairs can be made with polymers or mortars that are specially-designed to fill in the gaps. If there is lifting or sinking in concrete slabs, you should hire a professional to restore the structural integrity of the installation, so that restoring it will not end in eventual cracks or gaps. Lastly, if you have grease, oil, or chemical stains that are set on your concrete, you'll need to scrub the surface and apply a professional concrete cleaner.
Grind It Smooth
Industrial grinders are the best way to make your concrete floor, walkway, or installation blemish-free and ready to restore. Grinders remove surface imperfections with rotating discs that include various types of grits used in succession. You can rent disc grinders, but if you aren't familiar with the process of grinding, it's advisable to hire a pro. Choosing an appropriate grit, as well as using multiple discs to remove imperfections can be difficult if you aren't skilled in concrete grinding.
Finish With Resurfacing
Resurfacing mediums are products that have been designed to properly adhere to old concrete installations. A combination of mortar, polymer, and concrete bases, resurfacing mediums will stick to old installation where standard concrete won't.
Resurfacing mediums cost around $40 for a bag, in comparison to a $2 bag of concrete, but because you only need a thin layer to overlay an old installation, it's a bargain when the job's said and done. You'll also save a fortune in removing and re-installing over an old concrete installation.
Resurfacing mediums are thinner than concrete and don't need to be worked over to achieve a smooth result. You simply apply the medium in a thin layer over an old installation with a squeegee, then let it level over the entire surface by itself.
If you're resurfacing an old concrete installation, it's better to use a layer of resurfacing medium across the entire installation, rather than on only damaged areas though, so the look and integrity is continuous.
