Minwax High Build Polyurethane

Hi folks! I just did my first coat of Minwax High Build Polyurethane on my hardwood floor in my dining room. While I gotta say I'm very happy with the high gloss, I am shocked at how many air bubbles appeared in this application. Previously I've used Varithane on other projects and I didn't encounter this. Has anyone else encountered this in this product? I'm worried that it was my application (lambs wool) and I'm honestly dreading the sanding that will come prior to my second coat (which the can says is 8-12 hours, but it IS humid this morning, so...).

Thoughts? I'll keep everyone posted on the progress.

Welcome to the forums!

Did you use a pad or roller to apply the poly? The biggest cause for bubbles in poly is shaking the can instead of stirring it.

As Marksr stated,
the first time I used it I got all these bubbles- because I Shook the can.
