Cobber,

From here it doesn't look as though the boards have been primed, the coating is too thin. I'm not sure what is meant by "pre-primed", as I haven't heard the term before, but if it means "a thin white coating" as per your post then the boards have been pre-primed and are thus to spec. If you can, visit Bunnies or another timber supplier and look for examples of unprimed, pre-primed, and primed boards so you have a better idea of what was supplied.Quote:
Priming - For all cladding where a painted finish is required, boards should be primed all round with a solvent (oil) based primer plus one coat of undercoat, colour matched to the final finishing coat.
This will ensure that lines will not be apparent due to any shrinkage or movement that may occur later. Knots may be sealed with a 2 pack polyurethane or other sealer recommended by the paint manufacturer.
When you applied the paint, did you use a primer followed by an undercoat or did you apply two top coats?
If the later this may be a bigger issue in the long term than the cupping and warping is today. I suggest you seek advice from the paint manufacturer.
You also post that "not all have gone up yet" which implies that most of the boards are useable and have been incorporated into the work.
How many boards need to be replaced?
If it's not many, my advice is to aim for a deal where the builder wears the cost of the lost productivity because the boards are harder to handle and take longer to fix than they should and you wear the cost of any replacement boards.
As I read the information provided, your contract is written on the basis that you will do the painting, the boards supplied were to spec (i.e. pre-primed), you unstacked them, painted them, restacked them and the boards warped. I'm reading all this as project risks for which you elected to be responsible.
Even if the boards are not to specification, you have used them (painted them) and therefore knowingly accepted for incorporation what was supplied. You can't return them for resale, so it's no longer the supplier's problem. (Sorry)
As I said in my earlier post, the contractors I deal with would view this as legitimate grounds to claim a major variation because of the extra work involved so if it went to arbritation, you're unlikely to get much joy.

please forgive me for not being particularly sympathetic but if you try taking this to the lawyers you're likely to get badly burnt and I'd not like to see that.
