concrete etching

I have an open carport with polished concrete. Water will not absorb through it so it puddles and collects during rains. How can I 'de-polish' the concrete so it will absorb water? Tried muriatic acid with no luck.

concrete etching

If the floor is holding water [puddling],concrete supply companys will have a product of "Glaze n seal" paint and etching sample in black 1/2 pint can.these are free.Read all info. before use.Tape off 12" sq. area very well.apply the jel with stiff nylon brush. let set tell all action of jel has stoped.hose off with water. It will etch.But you still have to address the puddling.An over lay product will take care of that. If all else fails your expections, floor grinding is last costly resort . $2.50 and up per sq. ft. Good luck.

We all no alot but can only do a little,n.

its possible but unlikely the garage floor is polished,,, i'd guess its only been ' burnished ' w/helicopter ( powered concrete float ),,, you can rent a grinder & grind ( deblaze ) a dble car garage in a day - check w/your apron/vest store OR any rental shop
