Anyones else run into this?
I bought a couple of tins of Hammerite smooth a few weeks ago. One is fine. The other doesn't want to dry completely. One of the items in question (Panhard rod) was taken back to bare metal last Saturday and painted with the Hammerite. Nearly a week later, it has got to the stage where it can be handled, but it's still feels 'tacky'. And if it's layed down, it sticks to whatever it's on.
I've had a frost watch type heater right next to it for the last few days and it's made no difference!
It's nothing to do with the rod specifically. It's the same on several parts that were painted last weekend and early this week.
Now I've got to get the paint off so I can start again. It'll clog a sanding disc straight away, so I suspect I'll have to use thinners to try and soften it. Or maybe a hot air gun to try and blister it off.

when ive used hammerite in the past and not stirred it properly its had the same effect,
to remove the paint i would use thinners it will clean the surface at the same time,

I think I've stirred it OK. It tells you not to stir it too much!
Just had a reply on another forum that suggests using primer even though the tin says you don't need to. His experience was with a clean shotblasted item that took 2 weeks to fully harden :shock:
He then did another with 2 pack primer first and it was dry within the day.

tempreture can have a lot to do with paint drying
-
also not allowing it to dry between coats doesnt help.

I'd really like to give them a second coat....... but the first one isn't dry yet :lol:

It can be slow but a week is a long time; give Finnegan's a ring and ask them about it.
Hammerite cures rather than dries as such; really unless you put a second coat on while it is tacky you are suppposed to leave it about six weeks I think.
Like I said call them; they might just pay for the thinners if it was a bad batch.

Yes Hamerite cures, the only drying as such is to get rid of the solvents that hold the paint in suspension. IIRC you either put the secong coat on within 6 hours pr after 6 weeks once it's cured.
It wouoldn't be so bad if it was still any good but these days it's not worth the cost or the trouble.

i always use a in fa red panel heater that does it quick but the atmosphere can make it take a long time to

Petrol will take it off ..
check the batch numbers on the cans one of the batches may have been frozen before you got it , if so the store will have had other complaints.

hit it with a hammer? :lol:
not had that problem with hamerite, but i had some of that granville black paint and it took a week to go hard even then it was still sticky :|
