i use a sealer called hiac. you can google it. hiac will make the concrete a little slippery so i like to add a product called sharkgrip. its like a clear sand that is invisible to the eye and keeps you off your butt. you can spray just hiac but if your using sharkgrip you have to roll it on. either way is easy. oh yeah dont get hiac plus. way more shine but very slippery. good luck
