Is SPC vinyl flooring waterproof?

When choosing new flooring for areas like kitchens and bathrooms that see a lot of moisture, waterproofness is a key concern. Solid polymer core (SPC) vinyl flooring has exploded in popularity in recent years as an affordable waterproof option. But is SPC vinyl truly waterproof? Let’s take a closer look at how it’s constructed and its water-resistance capabilities.

What is SPC vinyl flooring?

SPC vinyl flooring gets its name from its solid polymer core construction. It’s composed of four layers:

  • Top vinyl wear layer
  • Printed design layer
  • Solid polymer core (SPC)
  • Bottom vinyl backing

The solid polymer core is made from limestone powder combined with polyvinyl chloride (PVC) and stabilizers. It makes up the thickest layer of the flooring, contributing to its durability, structure, and waterproof properties.

Is the SPC core waterproof?

The SPC core is inherently waterproof. PVC is a waterproof material, and limestone powder is impervious to water. During manufacturing, the SPC core is also made 100% waterproof by being thermally fused under high heat and pressure. This eliminates any gaps where moisture could penetrate.

SPC plank cores are extruded as one solid piece. The lack of seams, gaps, or spaces also prevents moisture from getting in. So the SPC core itself is completely waterproof.

Do the other layers make it waterproof?

Along with the waterproof SPC core, the other layers of SPC vinyl flooring also contribute to its water-resistance:

  • Top wear layer: This thin, clear vinyl layer adds wear protection. The vinyl is waterproof.
  • Printed design layer: Underneath is a thin layer that creates the visible color/pattern. It’s also vinyl, so waterproof.
  • Bottom backing: More vinyl on the bottom side makes the flooring stable and strong. The vinyl backing is waterproof as well.

So all four layers of SPC vinyl are made from waterproof PVC vinyl materials. When bonded together under heat and pressure, they create flooring that’s waterproof from top to bottom.

Is SPC vinyl 100% waterproof?

SPC vinyl flooring itself is 100% waterproof. However, installation can affect its water-resistance:

  • Seams between planks could allow moisture in if not properly sealed.
  • Incorrect installation or gaps can compromise the waterproofing abilities.
  • Water overflowing the edges for prolonged periods can still damage the flooring or subfloor.

So while SPC vinyl planks are inherently waterproof, they must be installed properly according to the manufacturer’s instructions to get the full waterproof performance.

SPC vinyl vs. other vinyl flooring

Not all vinyl flooring has solid polymer core (SPC) construction. Here’s how SPC vinyl compares to other types:

Vinyl Flooring Type Waterproof? Reason
Sheet vinyl No Backing and seams can absorb water
Luxury vinyl plank (LVP) No Fibrous backing isn’t waterproof
Vinyl tile No Groutable joints allow water penetration
SPC vinyl plank Yes 100% waterproof construction

The unique SPC core and vinyl layers make SPC vinyl plank flooring fully waterproof, while other vinyl flooring has limitations.

SPC vinyl flooring waterproof tests

In addition to the waterproof materials used, SPC vinyl flooring undergoes a series of waterproof tests by independent labs:

  • Dry floor exposure: Planks are placed over dry concrete and weighted down. This checks for water absorption from underneath.
  • Wet floor exposure: Planks are put over ponded water on concrete. This confirms no water penetration from below.
  • Water impermeability: The edges of planks are sealed and weighted in water overnight. No leakage indicates a completely waterproof barrier.
  • Static load: Weight is applied evenly to simulate normal use conditions. No moisture gets through, demonstrating waterproof stability.

By passing these and other wet/dry tests, SPC vinyl verifies its waterproof performance for real-world use.

Chemical resistance

In addition to waterproofing, the SPC vinyl structure offers chemical resistance from substances like hand soap, ammonia, bleach, alkaline, acids, etc. This prevents discoloration and damage over time.

SPC vinyl flooring care

While waterproof, SPC vinyl still requires some care to look its best:

  • Dry spills quickly – Don’t leave wet spills sitting for long periods.
  • Don’t flood floor – While waterproof, excessive standing water can still damage the structure.
  • Sweep and mop regularly – Normal mopping is fine, just don’t oversaturate.
  • Use non-abrasive cleaners – Avoid harsh cleaners that could scratch the protective vinyl layer.
  • Add felt pads to furniture – Prevents scratches from heavy sliding.

Following the manufacturer’s maintenance guidelines will keep your SPC vinyl flooring looking like new.

SPC vinyl cost

On average, SPC vinyl flooring costs $2-5 per square foot installed. This is very affordable compared to other waterproof floors like ceramic tile. And it offers a more advanced DIY-friendly click-locking system than laminate flooring.

SPC vinyl is cheaper than WPC vinyl, which has a wood-plastic composite core. However, WPC vinyl can have a more natural wood look.

Pros of SPC vinyl flooring:

  • Completely waterproof
  • Durable and scratch-resistant
  • Comfortable and quiet underfoot
  • Wide range of colors and styles
  • Easy DIY click-together installation
  • Affordable
  • Easy maintenance

Cons of SPC vinyl flooring:

  • Can show indentations from heavy furniture
  • Not as natural looking as wood floors
  • Plastic odor during initial installation
  • Not environmentally friendly

SPC vinyl flooring reviews

SPC vinyl flooring gets overwhelmingly positive homeowner reviews. It earns an average 4+ star rating for its combinations of waterproof durability, comfort, and attractive designs.

Many reviews praise the easy DIY click-locking installation. People are impressed it offers a great modern look comparable to hardwood or tile, but for a fraction of the price without professional installation required.

Negative reviews focus on the occasional hollow sounds or plastic odor during initial installation. A few people mention slight indentations from furniture, which is typical for softer vinyl flooring.

But overall, most customers are very satisfied with SPC vinyl flooring’s waterproof performance, aesthetics, and cost-effectiveness.

Pros recommend SPC vinyl

With its durable 100% waterproof construction and affordable pricing, it’s no surprise professional flooring contractors recommend SPC vinyl:

  • For basements, laundry rooms, kitchens, and bathrooms – Areas prone to spills, splashes, and high moisture.
  • For family homes with kids and pets – Its scratch-resistance and stain proofing ability make it ideal for active families.
  • For rental units or investment properties – Provides a beautiful and affordable floor covering with minimal maintenance required.
  • For homeowners doing DIY installation – The click-locking planks make self-installation straightforward even for beginners.

Installers say SPC vinyl stands up to water better than almost any other floor for a moderate price point.

SPC vinyl flooring manufacturers

There are dozens of quality SPC vinyl flooring brands to choose from. Some of the top manufacturers include:

  • Shaw Floors
  • Mohawk
  • Armstrong Flooring
  • USFloors
  • Provenza
  • Congoleum

When researching brands, look for options certified as 100% waterproof through third-party testing. This ensures each layer uses waterproof materials and components.

Higher wear layer thickness (14 mil+) also indicates better durability. And opt for reputable brands that offer at least 10 year waterproof warranties on their SPC vinyl flooring.

Conclusion

Thanks to its solid polymer core and multiple vinyl layers that are fused together into a tight, seamless unit, SPC vinyl plank flooring provides complete waterproof protection.

While 100% waterproof, SPC vinyl still requires proper installation to perform to its full abilities. Minimal care is also needed to prevent scratches and extend the flooring’s lifespan.

Overall, SPC vinyl scores top marks for water-resistance. Combined with easy DIY installation and affordability, it’s an excellent choice for wet areas like kitchens and bathrooms that need floors with superb moisture defenses.
