nope
do this and it will work
I had the "Storm of the Century"(they really named it that)come in the morning we poured my garage addition slab.
Every leaf from 3 counties ended up in slab. Guys picked them out as best they could but couldnt keep up. Pine needles where the worst.Heres what I did and its still good.
First pressure wash with a good pressure washer.Next acid wash with mild solution. I also rented a power sander but thats optional.
I was able to get alot of the leaves to pop out with the 0* pressure washer nozzle,
some had to be chipped out. I bought a 2 gallon kit of DOT epoxy used for repairing bridges from Lambert products.I think spec is 10,000PSI fully cured.
I used a 50/50 mix of it and DRY clean builders sand.Mix in the cone type drinking cups
and when ready to apply snip the end off and pour the defect full . Its key to over fill
and let it attach to surrounding flat area. Do not trowel,let it stand as a mound.Only mix a cup full as it sets quickly.
Let those areas cure for 24hrs then use a cup type grinding wheel made for concrete on a 4.5 inch side grinder. My old Black and Decker Industrial grade one would get so hot I had to wear 2 pairs of gloves to hold it,but its still going strong 30 yrs later.
I painted my slab but the paint has since worn off,repaired areas showing like battle scars but I have yet to have even one pop out ,rolling items weighing several thousand pounds on steel casters over it.
You do realize that was *last* century, don't you? We have a little over 84 years to have another with that name..........
