Water can damage vinyl flooring under certain circumstances. While vinyl flooring is generally water-resistant, prolonged exposure to water or excessive moisture can cause damage over time.

If water seeps into the seams or edges of vinyl planks or tiles, it can cause them to lift or peel.

If there’s moisture or water seepage from the subfloor, it can cause the vinyl flooring to warp or bubble.

Prolonged exposure to standing water, such as from leaks or spills that aren’t promptly cleaned up, can lead to water seeping into the seams and causing damage.

In cases of significant water exposure, such as floods or plumbing leaks, vinyl flooring can sustain severe damage, including warping, discoloration, and mold growth.

Is Vinyl Flooring Waterproof

Vinyl flooring is often marketed as waterproof or water-resistant, but the degree of water resistance can vary depending on the type of vinyl flooring and its construction. Here’s a breakdown:

Traditional Vinyl Sheet Flooring – Standard vinyl sheet flooring is typically water-resistant but not entirely waterproof. While it can withstand occasional spills and moisture, prolonged exposure to standing water or excessive moisture can cause damage over time.

Luxury Vinyl Plank (LVP) and Luxury Vinyl Tile (LVT) – LVP and LVT are engineered vinyl flooring options that often boast higher levels of water resistance compared to traditional vinyl sheet flooring. They are constructed with multiple layers, including a waterproof core, making them more resilient to water damage. However, it’s essential to note that while LVP and LVT are highly water-resistant, they are not completely waterproof. Prolonged exposure to standing water or flooding can still cause damage, especially if water seeps into the seams or edges.

WPC (Wood Plastic Composite) and SPC (Stone Plastic Composite) Vinyl Flooring – WPC and SPC vinyl flooring are subcategories of LVP and LVT that feature a rigid core made from either wood-plastic composite or stone-plastic composite materials. These types of vinyl flooring are known for their superior water resistance and dimensional stability. They are more resistant to water damage than traditional vinyl flooring and are suitable for areas prone to moisture, such as kitchens, bathrooms, and basements.

What Water Damage Looks Like

The effects of water damage on vinyl flooring can vary depending on the severity of the damage and how quickly it’s addressed. Here are some potential outcomes after water damage occurs:

Discoloration – Water damage can cause vinyl flooring to discolor, resulting in unsightly stains or patches.
Warping – Excessive moisture can cause vinyl planks or tiles to warp or buckle, especially along the edges or seams.
Peeling or Lifting – Water seepage can weaken the adhesive bond, causing the vinyl flooring to peel or lift away from the subfloor.
Mold and Mildew Growth – Moisture can create an environment conducive to mold and mildew growth, especially in areas where water has been allowed to accumulate for an extended period.
Odors – Water damage can lead to musty odors, particularly if mold or mildew begins to develop.
Structural Damage – In severe cases, water damage can extend beyond the vinyl flooring to the subfloor or underlying structure, requiring extensive repairs.

How to Repair Water-Damaged Vinyl Flooring

Repairing water-damaged vinyl floors depends on the extent of the damage. Here’s a general guide on how to repair water-damaged vinyl floors:
Start by assessing the extent of the water damage. Identify areas where the vinyl flooring is warped, discolored, or lifting.
If the damage is localized, you may be able to remove only the affected sections of the vinyl flooring. Use a utility knife to carefully cut around the damaged area and remove the damaged pieces.
Before installing new vinyl flooring or repairing the damaged sections, ensure that the subfloor is completely dry. Use fans, dehumidifiers, or moisture meters to determine the moisture levels in the subfloor and ensure it’s dry before proceeding.
If the subfloor has sustained significant water damage, it may need to be replaced or repaired before installing new vinyl flooring. Address any underlying issues, such as leaks or moisture intrusion, to prevent future water damage.
Once the subfloor is dry and any necessary repairs have been made, install replacement vinyl flooring. If you removed damaged sections, carefully cut replacement pieces to fit the area and secure them in place according to manufacturer instructions.
Use vinyl seam sealer to seal any seams or edges where water could potentially penetrate. This helps prevent future water damage and ensures a secure installation.
If you’re installing new vinyl flooring, allow it to acclimate to the room’s temperature and humidity levels before installation. Follow manufacturer recommendations for acclimation time.
To prevent future water damage, maintain the vinyl flooring properly by promptly cleaning up spills, using area rugs or mats in high-traffic or spill-prone areas, and maintaining proper humidity levels in the environment.
