Luxury vinyl tile (LVT) is a popular flooring choice for durability and style, but it can present several problems when installed or maintained incorrectly. This article outlines the most frequent issues, their causes, diagnostics, repairs, and preventive strategies to extend the life of an LVT floor.
| Problem | Common Causes | Quick Fix |
|---|---|---|
| Peaking/Buckling | Moisture, poor acclimation, over-tight seams | Allow expansion gap, control moisture, re-install |
| Gapping/Shrinkage | Low humidity, insufficient adhesive | Increase humidity, replace loose tiles |
| Discoloration/Fading | UV exposure, chemical reaction, staining | Use UV protection, replace affected planks |
| Surface Wear/Scuffing | Abrasion, inadequate wear layer | Use protective pads, consider refinish or replace |
| Adhesive Failure | Improper subfloor prep, wrong adhesive | Clean, re-adhere with recommended adhesive |
What Is Luxury Vinyl Tile And Why Problems Occur
Luxury vinyl tile is a multi-layered flooring product composed of a wear layer, printed design film, core (vinyl or stone-plastic composite), and backing. Problems typically arise from moisture, subfloor issues, improper installation, traffic, and environmental conditions. Understanding the product makeup clarifies why certain failures occur and what interventions are effective.

Common Problems With Luxury Vinyl Tile
Buckling, Peaking, And Lifting
Buckling appears as raised seams or tiles that do not lie flat. It is most often caused by moisture intrusion, lack of proper expansion gaps, or poor acclimation before installation. Symptoms include ridges at seams and areas where tiles separate from the subfloor.
Gapping And Shrinkage
Gaps between tiles happen when the floor contracts. This commonly results from low indoor humidity, temperature extremes, or adhesive failure in glue-down installations. Small gaps can collect debris and worsen over time.
Surface Wear, Scratching, And Loss Of Finish
Surface damage shows as dulling, scratches, scuffs, or worn-through patterns. High foot traffic, abrasive dirt, and insufficient wear-layer thickness are primary contributors. Wear-layer ratings vary; residential and commercial needs differ.
Discoloration, Staining, And Fading
Discoloration can be caused by UV exposure, chemical spills, rubber-backed mats, or reactions with certain cleaning products. Yellowing sometimes results from plasticizers migrating or from adhesives reacting with the vinyl.
Adhesive Or Click-Lock Failures
Glue-down floors may delaminate if the subfloor was not clean or primed, while click-lock LVT can come apart when under stress or poorly installed. Using the wrong adhesive or failing to follow manufacturer guidelines leads to premature failure.
Moisture-Related Issues
Excess moisture from below (concrete slab vapor) or above (plumbing leaks) causes swelling, mold growth under loose planks, and adhesive breakdown. Moisture-related failures are among the most common and costly to remedy.

Primary Causes Behind LVT Problems
Identifying root causes helps prevent reoccurrence. Key contributors include subfloor irregularities, moisture and vapor, improper acclimation, incorrect adhesive or installation method, poor product selection, and heavy abrasion. Each cause requires a tailored approach for diagnosis and repair.
How To Diagnose Problems Correctly
Accurate diagnosis starts with inspection and testing. Measure moisture in the substrate with a moisture meter, check flatness with a straightedge, and examine the wear layer and backing for defects. Photograph issues and note environmental conditions to guide repairs.
Tools And Tests For Diagnosis
- Relative Humidity (RH) Test using in-slab probes for concrete slabs.
- Calcium Chloride Or Tramex Tests to estimate vapor emission or surface moisture.
- Straightedge And Level to check subfloor flatness; most manufacturers have maximum tolerance specifications.
- Adhesive Bond Test by lifting a corner to inspect adhesive residue and adherence.
Repair Strategies For Common Issues
Fixing Buckled Or Lifted Tiles
Minor lifting can sometimes be resolved by releasing tension at seams and re-seating tiles. For glue-down LVT, remove and clean the subfloor, allow the area to dry, then reinstall with proper adhesive and maintain expansion gaps.Severe buckling often requires full replacement of affected sections.
Addressing Gaps And Shrinkage
Small gaps may be reduced by raising indoor humidity slightly during dry months. Loose or separated tiles should be re-adhered or replaced, ensuring proper acclimation and adhesive application.For click-lock floors, check perimeter gaps and refit boards if possible.
Repairing Surface Wear And Scratches
Light surface scratches can be minimized with recommended vinyl repair kits or polishing products designed for LVT. Deep wear usually requires replacing boards or tiles; using furniture pads and rugs prevents recurrence.
Dealing With Discoloration
Identify the cause before replacing flooring. UV-related fading can be reduced with window films, curtains, or UV-stable LVT selections; chemical stains may be removed with manufacturer-approved cleaners.Persistent yellowing often needs replacement.
Resolving Adhesive Failures
Remove affected tiles and scrape cured adhesive. Prepare the subfloor properly, use manufacturer-recommended adhesives, and roll the floor with a heavyweight roller during installation to ensure full contact.
Preventive Measures And Best Practices
Prevention focuses on site prep, product selection, proper installation, and maintenance. Always follow manufacturer instructions for acclimation, subfloor tolerances, moisture testing, adhesive type, and expansion gaps.These practices drastically reduce future problems.

Subfloor Preparation
Ensure subfloors are clean, dry, flat, and structurally sound. Concrete slabs require patching of cracks and leveling compounds where necessary; wood subfloors must be rigid and free of movement.
Moisture Control
Test for moisture before installation and install appropriate vapor barriers or primers if required. Address plumbing leaks and maintain indoor relative humidity between 35%–55% to reduce expansion and contraction.
Proper Acclimation And Installation
Store boxes of LVT in the installation space for 48–72 hours per manufacturer recommendations. Installers should maintain specified expansion gaps and follow layout plans to minimize waste and stress on the planks.
Choosing LVT To Minimize Future Problems
Not all LVT is created equal. Select products with thicker wear layers for high-traffic areas, a stable SPC or WPC core for dimensional stability, and proven manufacturer warranties.Verify UV resistance and compatibility with underfloor heating if applicable.
Comparing Core Types
Stone Plastic Composite (SPC) cores are very rigid and less prone to indentation, while Wood Plastic Composite (WPC) cores offer more cushioning. SPC tends to perform better in moisture-prone areas, whereas WPC may be more comfortable underfoot.
Maintenance Tips To Extend LVT Life
Regular cleaning and sensible use preserve appearance and performance. Use a soft broom or vacuum, damp mop with pH-neutral cleaners, avoid steam mops, and place mats at entrances to reduce grit.
- Prevent Scratches: Use furniture pads and trim pet nails.
- Clean Spills Quickly: Remove stains before they set.
- Use Compatible Cleaners: Avoid abrasive or solvent-based products.
When To Call A Professional
For large-scale moisture issues, widespread adhesive failure, structural subfloor problems, or when warranty claims are involved, professional assessment is recommended. Certified installers can perform moisture mitigation, full replacement, and warranty-compliant repairs.
Costs And Timeline For Typical Repairs
Repair costs vary by scope. Small repairs like replacing a few tiles may be inexpensive, while moisture mitigation or full replacement can be substantial due to demolition, subfloor repair, and new materials.Timelines range from a few hours for patch repairs to several days for moisture remediation and reinstallations.
Frequently Asked Questions
Can Luxury Vinyl Tile Be Installed Over Existing Flooring?
LVT can be installed over many existing floors if the surface is flat, secure, dry, and compatible with the adhesive or click system. Removing problematic substrates like worn vinyl or soft wood often prevents future failures.
Is LVT Waterproof?
Many LVT products are water-resistant or waterproof at the plank level, but installation can allow moisture to reach the subfloor. Proper perimeter sealing, underlayment choices, and substrate moisture control are essential for wet areas.
How Long Should Luxury Vinyl Tile Last?
Quality LVT properly installed and maintained can last 10–25 years depending on traffic, wear layer thickness, and environmental factors. Commercial-grade products with thicker wear layers will last longer in high-traffic settings.
Key Takeaways For Homeowners And Specifiers
