SPC Vinyl Flooring

What SPC flooring is made of

An SPC plank has a rigid core of stone plastic composite: mostly powdered limestone bound with vinyl, pressed into a dense, stiff board. On top sit a printed design layer, a clear wear layer that protects it and a hard top coat; underneath, many planks have an acoustic underlay bonded on. The stone-based core is what makes SPC so stable and dent-resistant compared with flexible vinyl.

How to choose SPC flooring

Wear layer

The wear layer decides how long the surface keeps its looks. Around 0.3mm suits bedrooms and living rooms; 0.5mm or more is better for kitchens, hallways, pets and children.

Thickness

Thicker SPC (including any attached underlay) feels more solid and quieter underfoot and bridges small dips better. Thinner SPC keeps the floor height down next to existing floors and under doors.

Attached underlay

Planks with underlay attached are quicker to lay and give consistent sound insulation. Planks without it need a thin, firm LVT underlay, never a thick, soft laminate underlay, which lets the click joints flex. Do not add a second underlay under planks that already have one.

Look

Choose the number of different plank designs (more means fewer obvious repeats), bevelled edges for a real-plank look, and embossed texture that follows the grain.

SPC compared with other vinyl

SPC vs WPC: both are rigid core click floors. SPC is denser, more stable and more dent-resistant; WPC has a lighter, foamed core that feels softer and warmer underfoot. SPC vs glue-down LVT: SPC floats and is quick to fit, even for a DIYer, and is forgiving of the subfloor; glue-down is thinner, very hard-wearing and best for large commercial areas, but needs a perfectly smooth subfloor and a professional fitter.

Fitting SPC flooring

1. Let the packs acclimatise flat in the room, typically 24 to 48 hours (check the instructions).
2. Make sure the subfloor is clean, dry and flat within the maker’s tolerance; fill dips and overlay old floorboards with plywood or hardboard.
3. Lay an LVT underlay unless the planks have one attached; on concrete, add a damp proof membrane if the maker requires it.
4. Click the planks together, staggering the end joints, and leave the small expansion gap the product asks for at the walls.
5. Finish edges with scotia beading or skirting, doorways with threshold strips, and seal the edges in bathrooms.

SPC cuts cleanly by scoring with a sharp knife and snapping, so it is one of the easiest floors to fit yourself. Our installation guides include straight-plank and herringbone SPC.

Looking after SPC

Sweep or vacuum regularly and mop with a damp mop and a pH-neutral cleaner. Avoid steam mops unless the maker allows them, rubber-backed mats, and dragging heavy furniture.

Common mistakes to avoid

• Adding a second underlay under planks that already have one attached, which makes the joints flex.
• Laying over an uneven subfloor: SPC hides small bumps, not large dips.

Where SPC works best

Because it is stable and water-resistant, SPC suits kitchens, bathrooms, hallways, utility rooms and homes with pets and children. In very hot, sunny conservatories, choose a product rated for heat and use blinds.
