Adam Schein doesn’t want to hear a peep from Mets president of baseball operations David Stearns during his team’s historic skid.

On Friday’s episode of “Schein Time,” The Post host ripped Stearns and the Mets, saying that it’s the exec’s fault for assembling a flawed team.

“You know what I would do?” Schein said. “I would honestly, if I’m David Stearns, not say a damn thing. Your roster, that you put together, is atrocious. It is shades of the ’62 Mets, an expansion team.

“And you spent all that money haphazardly, foolishly, on this flawed, embarrassing, pathetic, poorly put together roster.“

Schein then dug into the lack of success from the Mets’ pitching staff despite their large payroll this season.

“$350 million with two pitchers,” he added. “I mean my goodness. David Stearns should wear a bag over his head. That is awful. You signed Devin Williams, Luke Weaver. You got rid of my guy, Pete Alonso.”

Schein’s fiery remarks came after Stearns confirmed that manager Carlos Mendoza’s job is safe for at least the near future despite the Mets’ abysmal start.

“We know our record is not what we want, and we know we are capable of more,” Stearns told MLB.com on Friday. “We don’t view this as a manager problem, and we don’t intend to make a change.”

The Mets hold the worst record in all of MLB at 10-21, including a stretch where they have lost 15 of 18 games.

The ’62 Mets — which lost a then-record 120 games — started that season with a 12-19 mark.

Speculation about Mendoza’s job security sparked after the Red Sox fired Alex Cora and the Phillies axed skipper Rob Thomson earlier this month following disappointing starts from both teams.

“It’s hard for all of us,” Mendoza told reporters following Thursday’s 5-4 loss to the Nationals. “We’re in this together, it’s not easy, but we have got to keep going.”
