Many thanks for your reply. I have been away OS for work, so have not
had a chance to get back.

It is the "veranda" along the side of the house. A covered walkway to
our front door - not a lot of traffic though. The bubbling is from the
size of a coin to 3 or 4 times that size.

some tips on the "pressure wash and start over" may be handy in time
by the looks of it.

Many thanks, Mark

Hi

I applied a new coat ofacrylicpaintonconcretea couple of days ago.

I etched theconcretewith commercial etching solution and ensured it
was clean before applying thepaint.

It is nowbubblingin the heat of the day.

Is there any way to fix the bubbles? Should I puncture them?

MarkI looked at some of the thread, and your replies. This is a deck or
patio? My guess, if thepaintwasn't defective, is that you did not
allow sufficient time in dry weather for drying - 2 or 3 days min.Concretealways has some moisture, which is why water basedpaintis
best. Some idea of the size of the job and how extensive thebubbling
is will help. Small bubbles can be poked with a pin - it allows
moisture to escape, the bubbles flatten, and if thepaintfilm is
otherwise intact and secure they won't show as much. If there is
abrasion or if you pressure wash after, then, of course, the loosepaint
would likely come off.

Another possibility is that the acid wasn't washed off thoroughly and
the reaction continued after you painted, forming gas under thepaint
film.

If you need to pressure wash and start over, I can give you tips in how
to contain all the loosepaintthat comes off ) Hubby and I invented
a method when our condo (peeling very badly) was repainted several years
ago - the contractor was impressed )
