im tackling a project that involves two massive exterior walls with paint peeling everywhere and i want to make sure the prep work is topnotch. ive been looking into the best oil based primer options especially something that works well with spraying and backrolling techniques. right now zinsser oil based exterior primer is my go to because of its reliable adhesion and coverage but w/ the condition of these walls i wonder if theres an even better primer for this kind of challenge. any suggestions on alternatives that meet or exceed zinssers specs? im also curious about how different oil based primers handle extreme wear over time especially on heavily damaged surfaces. is it worth looking into higher grade options even if they cost a bit more or do you think sticking to under $20 products is the way to go? any insights or experiences with other primers would help make this decision.

peeling paint and massive walls sound like a battlefield, but if Zinsser's working, why change generals? however, for extreme damage, consider primers geared for industrial settings. they're pricier but tough as nails, and sometimes the extra dollars pay off in longevity and wear resistance.

Kilz and Benjamin Moore are both great if you want something that will last long. The latter is better I think if your surface is already weathered or something. Both are just slow to dry than Zinsser tho, if you get it. Zinsser is still at the top if its correctly applied.
 
Thanks for the insights! Zinsser is reliable but do you think industrial grade primers are worth extra cost for heavily damaged surfaces? Kilz and benjamin moore seem solid but would their slower drying times be a drawback for large scale projects like this?

Industrial-grade primers are absolutely worth the extra pennies

Kilz and Benjamin Moore are solid choices but you also might want to check out XIM Peel Bond

Thanks for the reco! XIM Peel Bond sounds promising, I'll look into it alongside Kilz and Benjamin Moore. Have you found Peel Bond to outperform Zinsser for adhesion or durability on tough surfaces?
 
I just wanted to circle back on my peeling wall saga, thanks to those who recommended XIM Peel Bond. I gave it a shot on those beat-up walls, and it worked like a charm.
