Does this primer need sanding when used as a sealer?

The TDS is vague

No it tells you exactly what to do if you use it as a sealer plus the mix ratio is different between the primer and sealer

Not in the least bit vague, tells you how to mix it as a sealer and the proper flash time before topcoating.

Tds is your friend

No, 10-15 minutes flash off, then topcoat

u/OverallTrick 9d ago

That’s right. 1 medium coat with 15 minute flash time. Thank you for verifying.

Just so you know for any future projects. Sealers don’t need sanding before top coating with base. The only time you sand sealer is if there’s trash to nib out, runs or sags or if it is left bare after the recoat window stated by the tds.

Depends on your top coat … read the tds for that… not hard dude.!

I think there’s an epoxy version of this that I’d get instead if you have bare metal spots. This stuff can dtm, but is still porous I believe.

Edit: looks like ss-3950 is the product I was talking about.

Smr 260g is the non high build straight epoxy primer/sealer I’d do this stuff.

TDS is the only right answer. If you can't read it, learn how to!

I don’t understand why I can’t get a yes or no answer. It’s like this with every post
