I have a concrete contractor currently redoing my driveway. I had
showed him a picture from a concrete technique website which I liked.
It showed a driveway using stamped colored concrete. The driveway
consisted of different sized squares and rectangles of various
colors.

When the contractor started the project, I did not anticipate having
anything separating the various square and rectangular forms other
than grooves. The contractor used cedar wood strips to construct a
matrix of squares and rectangles. He said the reason this was
necessary was because since each form would be a different color, you
needed to individually color each form (using a sprinkle on powder).

The issue now is that alot of the cedar wood now looks black (from
water) and or stained with concrete residue or rutted (from power
washing that the contractor did to clean the driveway) and the
driveway has not even been completed yet. I have let the contractor
know that I am not happy with the project (in addition to the wood
form problem, there were other problems in that the concrete hardened
before stamps could even be done; some of the forms were not even
colored; but lets tackle one problem at a time).

The contractor has addressed how he will deal with some of the
problems, but has not suggested any solution for the discolored and
rutted wood forms.

Any thoughts on whether wood was appropriate to use in the first
place, and what can be done to help fix the problem.

Contractor here used cedar to form expansion joints on the driveway. No
black discoloration or discoloration of concrete. They used a transparent
sealer after the pour. Seems to work. Been over 2 years now.

However, in my opinion, the wood strips should have been temporary to form
the geometric patterns in your case. The patterns are all eye-candy, serve
no function. Not expansion joints.

Probably was a really bad idea.

Stamped concrete looks easy when you watch it on TV, but it requires
lots of experience and skill, and can be really expensive. Sounds
like you hired a 'handyman" when you needed an "artisan".

Sorry to hear, but not much to do besides tearing it out and starting
over.

Thanks for your input. I live in a city of 300K so not alot of choice
in contractors. I have had work done by this contractor before, and
he was the most experienced contractor I could find (including stamped
work although not with a project identical to mine involving dozens of
individual forms colors and involving stamping).
