Demo an existing floor with 1/2 inch thick underlayment
Hey Joe. I watched the video called How to Demo Vinyl and 1/4 Inch Underlayment, then took a look at my floors with vinyl sheet flooring. The underlayment is 1/2 inch thick, perhaps because the existing floor was installed over the previous floor? I prefer to install the LVP directly on the main subfloor. Is there a reason I shouldn’t remove all the underlayment?
Also, the doorjamb has been undercut 15 mm from the main subfloor (circled in red); however my planks are 7 mm thick including the attached pad. Do you have any suggestions how to fill the gap that will remain after installing the new floor?
