Do I Need A Moisture Barrier Under Vinyl Flooring?

Whether you need a moisture barrier or not depends on the subfloor you are going to install the vinyl flooring. 

If you are going to install vinyl flooring over a concrete subfloor, you will be needing a moisture barrier under vinyl flooring. As concrete subfloor can soak up moisture, a moisture barrier will reduce this risk.

Can Mold Grow Under Vinyl Flooring On Concrete? 

Vinyl flooring itself is waterproof flooring so there is very little chance that mold will grow under vinyl flooring on the concrete subfloor. 

However, despite having little chances mold can grow under vinyl flooring on concrete due to excess moisture or standing water.

Also, if any wet object is around the perimeter of the baseboards or grooves of the planks can become a great source of food for molds, therefore, mold can grow. 

Another thing is, concrete may soak up moisture but it can’t soak that much that will give birth to molds underneath vinyl flooring on concrete. 

Do You Need To Waterproof Under Vinyl?

You are required to waterproof under the vinyl flooring. Because moisture can build up underneath vinyl planks where there is negative pressure on the subfloor, that can result in coating and adherent failure. 

Therefore, when you waterproof under the vinyl flooring, it will prevent building up the condensation underneath the flooring planks. So, the flooring will not get water/moisture damaged. Also, it will last for a long time. 

Due to being made with 100% water-resistant materials, vinyl floorings are waterproof. However, you are suggested to follow all necessary methods to protect the flooring from getting water damaged.
