[s-cars] NAC: Garage floor

Hi,
You need to chip the area around the broken area to make sure you don't  have 
any loose concrete in it.  Then you use a material called Masterflow  713 
grout.  It is non-shrinking and hold up very well.  One added it  to add adhesion 
to this patch, is paint the chipped area with the Concresive and  while it is 
stick wet or tacky, apply the Masterflow.  Don't make it too  wet, so it will 
stand up instead of trying to level out.  Nether the  Concresive or 
Masterflow have a lot of set up time.  So you need to be  ready to work it.
 
I would do a Google search to find both these products near you.

Good  advices!

Where do I even get this Concresive 1001 LPL ?

Also, I  have a problem with garage entry. Concrete chipped badly. Is there 
any way to  fix that permanently? Or at least for 5 years or so?

Hi,
It all comes  down to prep work just like painting a car.

When you place concrete, it  forms a film on the top basically sealing the 
concrete.  You want to  remove this.

The best way to make any paint stick to concrete is to  create what they call 
a profile on the surface you are applying the epoxy to.  In creating a 
profile, you are roughing up the surface you are going to paint.  Sanding concrete 
won't work well and is time comsuming.   Profiling  the concrete creates small 
ridges in the concrete, increasing the surface  tension area to be coated.  

I would get a small chipping gun, get  a small gad, that looks like a meat 
tenderizer, and run this over the whole  are of the floor.  This will give you a 
great profile for surface tension  for the epoxy.

By the way, this is how we do the concrete floors in the  power plants for 
the Power Utility I work for.  These floors get a lot  more abuse than your 
garage ever would.  All comes down to prep.  I  will let some else advise you on 
the epoxy to use, because the stuff we use is  over 300 dollars a gallon.

As for cracks, use Concresive 1001  LPL.  This works great on cracks.  Just 
mix up as much as you want,  two parts, like in a paper cup or a grout bag.  
Just pour or squeeze it  into the cracks.  Of course, it will fill up any void 
you have under the  concrete, so you could use quite a bit if you have a large 
void under the  crack.  You could also coat your entire floor with this stuff, 
but it  would cost you your right arm.  We sometimes use it to line clay 
pipe, if  fluid seeps through,  It seals the inside of the pipe.

There are  also come concrete crack injection systems on the market you could 
 try.
