can i put herculiner over epoxy primer? i'm going to put the herc on my cab floor (old and new sheetmetal), new fiberglass running boards and a old piece of steel that is my bedfloor. can i shoot all these with epoxy primer, give it a long cure and herc right over the primer? we learned our lesson on putting some on acrylic enamel, don't want to go through that again. i can call herculiner, but thought i would start here. thanks, dick r

 

I'd call herculiner, I think they might rather you put it over scuffed bare metal but not sure. I'm wanting to use it in my cab too, let us know what they recommend.

 

I'm thinking of doing something similar too. I'll be curious what they have to say.

 

Here's what my local paint supplier says about epoxy primer or sealer. They dry very hard, so top coats should be applied either in the first few days, or they should be scuffed. He says use scotch brite pads to scuff it, and you'll be fine. I would think that if you're applying it over cured epoxy, scuffing it and blowing the dust off should be fine. I just saw that pep boys has a $20 mail in rebatefor herculiner bringing the price from $89.99 to 69.99.
Dick, if you're doing this to quiet the cab down, there are other products that will work better. A dynamat like product is Peel and Seal. Lowes carries it in the roofing section. Don't mean to go off topic so if that's your goal, let us know and we can discuss.
Rusty

 

My "EZ Liner" (same but different!) instructions states;

1. "Loose paint/rust should be removed and primed. Bare metal areas should be primed" (Doesn’t say with what)??????

2. Scuff/sand area with 80/120 grit sandpaper. Blow and wipe clean".

So Dick what happened when you applied the herculiner over the acrylic enamel please?

Thanks, Ray.

 

Yes...not only CAN you, but you SHOULD. A good 2K DTM primer will ensure a good bond to the metal and will prevent rust. A good scuff is all you need, wipe off the dust with a prep chemical or use enamel reducer, then apply the liner.
I'll second Old F1's question...what's the story on the acrylic enamel? Bedliner products are routinely applied to painted beds...I'm sure many have acrylic enamel...this is the first I have heard of a problem. Curious.

 

Here's a pic of the Herculiner I used on the raised tread of my running boards. Brushed on over a base of 2K Epoxy primer and urethane primer. Been on for several years now and very happy with results.

 

Now that looks good!

 

I agree!

I think I'll do this as well, thanks.

 

sounds like if you give the epoxy enough time to cure, scuff it up, should be ok. story on our acrylic enamel is that we painted a cab interior with it, we painted the floor as well, thinking it can't hurt. a week or two later, started putting down a bed liner (wasn't herculiner brand: something from advance auto i think) and it softened up and crinkled the acrylic enamel. it softened it up so much, we scraped it all off with a putty nice, let it dry, sanded it and put liner down again: no problem. maybe our acrylic wasn't cured enough. i'm not doing it for sound deadening, i just like the looks of it on a floor, running board etc. will call or email herculiner just for ref. and post here. dick r.

 

What type of acrylic enamel did you use? Sounds like the "bedliner" product had some lacquer-based chemicals in it. It probably wouldn't have lifted if the acrylic enamel had been catalyzed.

 

i'll check on the brand of bed liner and the enamel when i get a chance, we did that project at my brother in laws.

 

………………..what he said !!

 

ok, we used "restoration shop acrylic enamel" from tcp global and duplicolor bed liner from advance auto. as i rem (a year ago, it had paint, reducer and hardener). don't believe i saw the word catalyst on anything.

 

hardener = catalyst

That should have set up hard overnight………………..but when you mix people and chemicals anything can happen, ……….just look at some of the guys on here. (tee hee)
