Did I ruin my saw blade?

I used my circular saw to cut PVC pipe, and then it wouldn't cut wood, kept getting bound up. It even had a hard time getting through 1/2" drywall.

Did two 18" runs through PVC pipe ruin the blade?

Is it carbide? If so, cutting pvc won't dull it but cutting drywall with it sure will. Pvc can coat a blade with melted plastic, making it drag in wood. Cleaning the blade in solvent or a blade cleaner often solves that problem. But if you tried to cut drywall, it's likely toast.

If I'm in/near my shop I use my miter saw to cut PVC - never had any issues from doing so.

Got to ask, why did you use a skil saw to cut drywall? Besides the blade, all that dust isn't good for the motor.

Yrs ago I was painting some condos and the carpenters forgot to frame up kitchen soffits. To lessen their backcharge they also hung the drywall after they framed up the soffit. The dust cloud was so great I thought the bldg was on fire.

Not carbide, just the standard, general use blade that came with the Ryobi battery-powered saw, part of a basic set of drill & saw. After cutting the pipe and failing to get through whatever wood I was cutting (don't remember but nothing very thick or hard) I thought maybe the battery was dying. I only had about a 15" to 20" cut to make on the piece of drywall so I gave it a shot and it seemed to struggle. After a full charge it was still binding up on wood.

Just buy a new blade.
Never cut drywall with a saw. Score it and break it.

It is Ryobi so not the best quality to begin with and blades that come with saws are not the best even when new.
