What is Vinyl Plank Cupping?
Cupping is the most common problem of vinyl planks. After a certain period, the sides start to rise, making the board look like a cup or concave. This mainly occurs because of the temperature difference between the top and bottom of the board.
It occurs because the material expands and shrinks with the change in moisture content.
Sometimes the cupped floor problem is solved automatically when the temperature becomes normal as before. However, sometimes it becomes permanent and requires expert inspection.
5 Reasons for Vinyl Plank Flooring Cupping
Vinyl plank flooring cupping is the most common issue reported by most homeowners. Although the concern is severe, many are still unsure about the root causes. We’ve researched and pointed out the 5 most common reasons and proven ways to fix them.
1. Change of Seasons
One of the primary causes of cupping is the seasonal change. For example, summer produces more moisture in the environment. Floor beds get affected by the change in humidity. Moistures get accumulated under the plank floors, which results in cupping.
2. Faulty Plumbing and Leaks
Sometimes faulty plumbing can cause cupping issues. The floor usually fits tightly to each other like jigsaw puzzle pieces during fitting. If there is a leak or gap between floors, moisture can easily seep under the plank beds.
3. Wet Subfloor
When the moisture content is high in your room, there is a good chance of water seeping under the floor beds. Check your floors occasionally if you reside in a high humid area.
4. Liquid Spills
These floors are water-resistant, sometimes waterproof too. Yet, water can leak through the grout. If you leave the spilled liquid, it can seep and accumulate underneath the tiles. Thus cupping occurs.
5. Moisture Content
The right amount of moisture content is a must for installing the vinyl floors. Experts will take the moisture reading of your environment before installing the flooring. Low moisture content causes swelling of the boards. The boards turn into a concave shape if the moisture level is wrong when installed.
Solution to the Cupping Problem
Change in moisture, temperature, or leaking water can reportedly cause cupping. A proper diagnosis is necessary to understand the correct origin. Let’s learn the best methods to prevent or cure the cupped floors:
- Inspection of basements and subfloors before installing the planks.
- Turning off the AC fans to avoid condensation.
- Using dehumidifiers to control the humidity in humid areas.
- Avoiding venting in the crawl spaces to prevent mold.
If you’re finding it difficult to get into the heart of the problem, get an expert opinion. Industry experts have years of experience to solve the issues.
What causes vinyl plank to Cup?
Heat, sunlight, and moisture are the primary causes of cupping. Variation in the temperature and moisture prompts expansion and contraction of the material. Thus, the plank floors start to cup.
How do you fix vinyl plank buckling?

- First, remove the buckled pieces gently.
- Soften the adhesive with mineral spirit, and remove the residual glue.
