is vinyl flooring warp in heat?

Yes...

Reason

Warping - when there are temperature changes, your vinyl plank flooring might expand, and that’s what we call warping. You might experience it during the installation process if your floor is exposed to direct sunlight. Also, warping can happen if you use glue-down planks and there is water spillage.

Take measures

Scrape away any existing adhesive that has failed, softening it with a hairdryer if necessary. Apply new adhesive and work the vinyl tile back into place. Roll over the area to smooth out the buckled area and ensure proper adhesion of the adhesive. Place a few weights on the floor while the adhesive is drying.
