Hi marek thanks for the question.
Can you put vinyl flooring over carpet pad.
The most common type of floors floated over carpet are vinyl and laminate given they are budget friendly and feature a simple interlocking system of installation.
Temporary flooring can be what breathes new life into a space without breaking the bank and spending a lot of time tearing out carpet.
This is a soybean oil based polymer blend that is safe for all hardwood floors finishes and laminates.
You should not glue the pad and carpet together and then glue it to the vinyl as this would cause too much work if it ever needed to be removed.
First of all please contact your floor manufacturer because they will have specific guidelines for your floor type.
For better results you can use a carpet pad under the carpet.
For best results when dealing with a remodeling project you need to strip the carpet the padding and everything else all the way back down to the original rough flooring for the home which is probably particle board or plywood.
You can find vinyl underlayment with sound dampening qualities.
This pad should be laid down right over the vinyl but not over the carpet runners.
I would not advise going this route as the subfloor will not be properly installed or secure.
Installing over carpeting when indoor and outdoor carpeting is glued down removing the carpeting to get to the hard surface underneath can be a daunting undertaking.
As a rep for lvt products for over 30 years i m telling you that one it voids the warranty to use carpet padding under it.
I would suggest removing the carpet underlayment and use a sound rated vinyl pad that meets your lease specifications.
Installing allure flooring over plush indoor carpeting should not be attempted because as you walk on the vinyl flooring the carpeting underneath will give significantly.
