Polyurethane garage floor paint problems

Anyone any experience or suggestions?

Around a month ago I put two coats of sealer/ primer on my garage floor. I was running short of time so when I put the final [Hi Build] coat on, after noticing a lot of consensation on the new primer, I wiped it dry and put the top coat on.

I have returned to the property and the top coat is lifting in places.

I don't really want to sand the whole floor, so a nice helpul easy solution like whop a load more paint on top would be greatly appreciated :-)

I don't think you have any option but to remove loose stuff and at least abrade the surface to key the new coats.

This paint, from what I recall is like the stuff people spray on their walls but it has to be done on a dry surface or the effect looks like dandruff in a few months. The first coat is there to bond to, so if its not bonded, as it was on a wall here the guys had to remove it all and redo a coat of the underneath stuff then respray its top coat again.

You have effectively trapped water between the layers so my guess is that it will never bond now. Brian

Yes!

As I suspected there isn't a quick way out.

The base coat was put onto dry concrete, when I came to do the top coat the floor was wet, I assumed condensation, gave it a quick wipe and top coated.

Another "time saving" short cut!

Just off to town to buy a Bosch combii drill. My Aldi 55 Euro "bargain" conked.

I really should learn, no shortcuts and no cut price tools.

Many thanks
