Epoxy primer

[boatbuilder]

Ok, so its a bit of a disaster.

Apparently the supplier of the epoxy primer (metalflake) had the wrong description of the product on their site.
They sent me the epoxy paint, hardener and thinners, but failed to tell me that the paint also needed a tinter added before it can be used. So it all has to come off the entire roof of my camper van..... I am so mad

Especially since I had this email exchange with them before ordering...

This is the first time I’ve used the epoxy primer, so could you make sure that what I’ve ordered is compatible with each other?
Thanks,
David

David it is fine i will put a data sheet in the box for you.
Thank you.

It doesn't have to come off mate, just let it dry and then rekey and put the new stuff over the top. It will be fine

I'll leave it and see if it hardens properly...

I used 500ml of epoxy, 250ml hardener, but the 500ml of epoxy didn't have any tinter so the ratio would have been out a bit?

This is what i suspected. Im lucky enought to have a lechler supplier near by with all binders and tinters

Recently I changed to using epoxy primer on my car rather than etch primer. I have been using it in light grey under white COB and been pleased with the result.

I am thinking of getting epoxy primer in black to use on suspension parts, axle and prop shaft without putting a top coat over it. My assumption is that, due to it not being porus and being out of direct sun light, this should be alright. Is that so?

Can't be sure but it did take 3 yrs of direct exposure on my trailer before it started chalking up, it was outdoors uncovered etc. So could be OK, on the other hand a quick coat of cheap topcoat black wet on wet would guarantee it from UV with minimal faff. Did this on my Landy.

The stuff i had dried exactly the same as usual, I'm still not sure of their explanation though.

It looks like its drying ok, 24 hours and I can still dent it with my nail a bit....feels just very slightly rubbery, but definately harder this evening than it was this morning.

I found a Lechsys supplier in Dublin and called into them today, I just happened to be going to the airport anyway. They added some tinter to my paint for €28.

Not sure how I should rub it down now before I apply the correctly tinted stuff? Dry/wet? Grade of paper?

Might try some Jotun Jotamastic after this stuff runs out, as its got one less component to buy than the Lechler stuff.

 

[sprayerDrew]

Its All down to what works for you. I order it tinted in 5litres and the tinting doesnt cost any extra no matter what quantity. Id scuff it with 240dry or something alike as when it cures its as hard as cement ha

Some photos of the 2nd coat of primer on the roof...... I rubbed down the first coat with 180 grit wet...tried it dry but it clogged up all the time. Then washed and panel wiped, then sprayed.

As i said above i don't believe their explanation, even without the tinter it will be hard the next day.

Hi, What fluid tip is best for spraying the lechler 29107 epoxy, would a 2.0mm tip be large enough?

 

[langy]

I use a 1.8 or 2.0, which ever is handy at the time.

[vdubz]

Cheers, i will use the 2.0 then. i thought i may have needed a bigger tip as it seems like thick stuff. guess it thins down alot once mixed with hardener and 10% thinners.

Also was thinking of ordering some POLYESTER SPRAY FILLER (polyfan rush)from metalflake.co.uk to spray straight over the epoxy, has anyone used this stuff and is it any good?

 

[Country Joe]

No, but Langy has, and he said it was fine!* - (Sorry Langy)

Yes it does mate.

[langy]

Yes its fine BUT be aware it needs overcoating asap as it sucks up moisture like a sponge, my advice would be get it on, flat quickly and then 2 coats of epoxy over the top.

I have finished prepping my engine bay and have given it 2 coats of epoxy followed by 3 coats of high build which is now sanded ready for top coat, what i would like to know is can i thin down the epoxy (lechler 29107) and use this as a sealer before i basecoat/clearcoat?
