If you're looking to install laminate or hardwood floors without using an underlayment, there are a few things to consider. Laminate planks that don't have it glued yet should be installed with subfloor rolls. If the laminate has a built-in underlayer, you can place it directly on the hardwood floor. If not, you'll need to spread it out and tape it to the wood before installing the laminate.
It's important to make sure the hardwood boards are in good condition and that the subfloor is sturdy. If not, you'll need to buy a thicker floor. You'll also need a Visqueen vapor barrier if you're installing on a concrete slab subfloor. Laminate flooring is an economical option that can be quickly installed with little or no work.When installing laminate or hardwood floors without an underlayment, it's important to take your time and measure twice.
Moisture problems and uneven subfloors can cause laminate flooring to fail, so it's best to invest in a subfloor if you're on a budget but don't want to compromise the visual appeal and durability of your floors. The high compressive strength of the subfloor will also ensure that it won't contribute to decoupling from the floor. However, if you have a dry climate, impeccable subfloors, and little need to control noise, then an underlayment may not be necessary.
