Whether you need a vapor barrier under Luxury Vinyl Plank (LVP) depends primarily on your subfloor. Always check your specific product's warranty requirements, but use these general rules of thumb:
Water vapor can cause serious damage to your home. For instance, if your flooring gets wet, it could cause mold and mildew, and even destroy your floor (source). No one wants that, so vapor barriers are there to help prevent the floor from getting wet.
Short answer: yes, mould can grow under vinyl flooring — but only when moisture gets trapped between the planks and the subfloor. Vinyl itself is non-porous, so the planks don't host mould.
Yes, you can install Luxury Vinyl Plank (LVP) directly over plywood. However, because LVP is flexible and conforms to the shape of the surface beneath it, proper preparation is essential to prevent bumps, squeaks, or separated seams.
15 Mistakes to Avoid When Installing Glue Down Vinyl Plank Flooring
Yes. Both dry and wet Swiffer mops are safe to use on vinyl plank, as long as you're using cleaning pads that don't leave behind residue. Just avoid soaking the floor.
Luxury Vinyl Plank (LVP) is a popular, waterproof flooring choice, but it has significant downsides. Its major drawbacks include vulnerability to heavy furniture dents, fading from direct sunlight, and total inability to be refinished. Furthermore, poor-quality options often suffer from brittle locking systems and emit VOCs.
What are the most popular vinyl plank flooring colors in 2026? Light oak, greige, and soft brown tones continue to be favorites. These colors feel fresh and versatile, working well with neutral palettes, natural light, and the relaxed, airy look many homeowners are going for right now.
Underlayment is the layer of material that's installed between the subfloor and the flooring. It works as a part of your overall flooring system, which consists of the joists, subfloor, underlayment, and the flooring surface.
For plywood subfloors, the best underlayment for vinyl plank flooring (LVP) is a high-density, thin underlayment (1.5mm to 3mm) made of acoustic foam, cork, or synthetic felt. Avoid thick, soft, carpet-like pads, as plywood subfloors already absorb sound, and too much cushion causes LVP locking joints to snap.
Luxury Vinyl Plank (LVP) flooring typically lasts 15 to 30 years, depending on the quality of the planks, the thickness of the wear layer, and foot traffic.
Yes, Dawn dishwashing soap can be used to clean luxury vinyl plank flooring. Just add a few drops to a bucket of warm water. This mixture is excellent for removing grease and grime, especially in kitchens. However, be cautious not to use too much soap, as it can leave a film that dulls the floor's shine.
Dust, adhesive residue, and paper-backed underlayment can all feed mold under your floor. Add trapped moisture and a warm room, and mold can start forming fast. According to FEMA, mold can begin growing on damp surfaces in as little as 24 to 48 hours. That's why what happens before your vinyl goes down is so important.
No, standard Tyvek cannot be used as a traditional vapor barrier. Tyvek is a housewrap designed as an air and moisture barrier. It keeps bulk water out but is highly vapor-permeable, allowing moisture to escape the wall to prevent rot and mold.
Yes, a vapor barrier is highly recommended—and often necessary—between concrete and vinyl flooring to prevent moisture damage, mold, and to protect your warranty. Concrete is porous and constantly releases moisture vapor, which can become trapped under vinyl, leading to cupping and joint failure.
Cleaning the concrete removes dirt, dust, and debris that can interfere with the adhesion of the underlayment and flooring. A clean surface also helps prevent the growth of mold and mildew. Concrete must be completely dry before installing laminate flooring. Moisture can cause the flooring to buckle, warp, or rot.
Preparation Mistakes That Lead to LVP Installation Failure
Any uneven spots, old adhesive, or leftover debris from an existing floor can transfer through luxury vinyl or stress the locking system. The result is a floor that moves, clicks, or separates. Moisture conditions matter as well.
No, a floor does not have to be perfectly level for luxury vinyl plank (LVP), but it must be flat. While a floor can slope, it cannot have dips or high spots that cause the planks to flex and the locking mechanisms to break.

The healthiest flooring options for your home are those that are low-emitting, hypoallergenic, and free from volatile organic compounds (VOCs) and toxic adhesives. The absolute best choices for indoor air quality and chemical sensitivity are solid hardwood, ceramic or porcelain tile, and natural linoleum.
Yes, you can place a refrigerator on top of vinyl plank flooring. Because the floor is highly durable and waterproof, it easily handles the weight and potential spills of a fridge. However, as with any heavy object on a floating floor, taking a few precautions prevents damaging the planks.
