concrete porch finish too smooth

I have a concrete porch, was finished way to smooth, when rains is very slippery
How can I rough it up , refinish or paint over?

Most paint reviews seem prettu bad?

Would just an strong acid etch (like Rustoleam) and stiff brush work?

Any ideas appreciated

Muratic acid is used on fine finished concrete to open up the 'pores' of the concrete where it will accept paint/stain ..... but I'm not sure that will help with the slippery when wet issue.

Etch the surface first, to clean and provide a good bond for paint. Then use a "quality" (brand-name) quality paint, onto which you broadcast some carborundum grit or a hard quartz/silica or even garnet sand, while the paint is still wet. With a paint topcoat to lock the abrasives into place.

While only observing its use instead of using it personally, I'm familiar with carborundum grit often used as a surfacing additive in concrete floor finishes, to make the finished surface "not slippery." It's the usual additive for industrial (factory) floor finishes. I have used quartz/silica sand with oil-based enamels, most recently on steel motorcycle lift surfaces (very successfully), where good tire-traction was extremely important.

I'm not fond of the 'sand' type grit they sell at the paint store to add to floor paint. It does a good job initially but it doesn't take too much time for the traffic areas to wear back smooth I don't know if there are different types of grit that can be added to paint or if one type fares better than another
