Yes, installing underlayment underneath the laminate flooring is necessary. The underlayment has many benefits like preventing water damage to your subfloors, insulating the floor for sound, and providing an even surface for the planks to sit on.

When you skip the underlayment, you can end up with serious issues, including water damage to your subfloors, noisy planks, and an uneven floor.

Steam mops can be a better option than traditional mops because the steam can lift stubborn dirt from floors without using chemicals, and it also kills bacteria and dust mites. However, steam mops have drawbacks: they are more expensive, require an electrical outlet, and are not suitable for all flooring types, such as laminate or hardwood, which can be damaged by the steam.

Regular mopping can also sanitize floors effectively when done with the right cleaning products and techniques, though it may require more effort. The main advantage of a traditional mop is its versatility, as it can be used on any type of flooring. Ultimately, the best choice depends on your floor type, budget, and cleaning preferences.

There are a few different types of finishes to choose from for the final step of the project. 

Water-based polyurethane sealants emit fewer odors and fumes but dry quickly, which can pose a challenge when trying to get a smooth coat. Oil-based polyurethane sealants let out more odors and fumes into the air (it’s especially important to wear a respirator if you choose this type), but they take longer to dry, which can be more forgiving during the finishing step. 

Some may prefer wood oil to polyurethane because rather than creating a layer, it becomes part of the wood. Wood oil takes longer to dry, and is less resistant to wear and tear; however, it creates a natural-looking result by enhancing the grain of the wood. 

Yes, you can put rugs and carpet on heated floors. However, carpet is not the most efficient for heated floors. The carpet pad and pile can prevent the heat from penetrating into the room. Rugs may also prevent heat from reaching your feet. You will get the most from your heated floors if you use thin rugs so that a maximum amount of heat can penetrate the room. You may find you do not need rugs to warm a space, thanks to the radiant heat coming up through your feet.
