Kitchen Glass: Splashbacks, Cabinet Doors and Back-Painted Panels

Why Glass Beats Tile Behind a Cooktop

A glass splashback is one continuous, grout-free surface: nothing to scrub between tiles, no grout to discolor, and a face that wipes clean in seconds. It reflects light around small kitchens and takes any color — which is why it displaced tile in most modern renovations.

The Right Glass: Painted Tempered, 6 mm

The industry-standard splashback is 6 mm tempered glass, back-painted. Paint glass uses low-iron or clear float back-coated with two layers of lacquer, fired for adhesion. The substrate choice matters more than most buyers realize: clear float's iron content mutes and greens light colors behind it, so whites, creams and pastes are specified on low-iron to stay true — deep colors can sit on either.

Tempering is non-negotiable near heat and for breakage safety — and it means all cutouts happen first: socket cutouts, window reveals and rangehood clearances are CNC-cut before the tempering furnace, from template-accurate site measurements.

Heat Zones: What Glass Can and Cannot Touch

• Behind induction and electric cooktops: fine — splashbacks are designed for exactly this, typically 50-75 mm above the benchline.
• Direct gas-flame contact: never — open flames need a stainless or tiled zone directly behind burners.
• Behind ovens: acceptable with the oven's own heat shroud intact; check the appliance manufacturer's clearance.
• Above rangehoods and near wall ovens: standard practice; tempered glass handles the radiant heat comfortably.

Cabinet Doors: Fluted, Frosted and Painted

Kitchen cabinet glass has its own logic: 4 mm is the workhorse thickness for framed doors, with fluted patterned glass leading the design trend for upper cabinets, acid-etched glass for a soft uniform frost, and clear glass for display cabinets. Painted panels in the splashback color turn cabinet fronts into a continuous color block — a signature of contemporary European kitchens.

Ordering Without Surprises

• Measure with templates around sockets and windows — glass hides nothing behind it.
• Order color samples on the actual substrate (low-iron vs clear) — paint chips and photos both lie.
• Specify polished edges everywhere; splashback edges sit at eye level.
• Plan the mounting: neutral-cure adhesive on a painted, dust-free wall, with mechanical support for panels above cooktops.
• Batch all kitchen glass — splashback, cabinet doors and mirrors — from one production run for exact color match.

Inside a Quality Back-Painted Panel

The paint system

Two separate coats are the minimum for a durable panel: a primer or first color coat for adhesion, then a top color coat for opacity and finish, roller-applied and oven-cured between coats. A single thick coat hides cheaper, but cures unevenly and scratches off at edges within a few years. For commercial kitchens and high-wear projects, ceramic enamel fused into the surface at around 700 degrees C is the heavy-duty option — it cannot be scratched off at all, but costs noticeably more and suits a narrower color range.

Edges before paint

Edges are polished before coating, not after. A raw cut edge under paint shows as a dark seam at eye level and is the point where moisture eventually attacks the lacquer. Good production also lightly arrises corners so the coating wraps cleanly instead of thinning out over a sharp arris.

Substrate and color truth

The same lacquer reads differently on clear float and low-iron: through a white paint, clear substrate pulls the color mint-green. Manufacturers control this with a color tolerance target — ask what delta-E range your color is matched within, and always approve a sample sprayed on the exact substrate and thickness you will receive. A chip approved on cardboard tells you nothing.

Installing a Splashback: Step by Step

1. Let the panels acclimate to room temperature for 24 hours so adhesive and lacquer cure under stable conditions.
2. Confirm the wall is fully finished, sealed and dust-free; prime porous or chalky plasterboard before any adhesive touches it.
3. Dry-fit every panel with its cutouts over the sockets and check 2-3 mm gaps at benchtops, corners and window reveals.
4. Run vertical beads of neutral-cure panel adhesive every 150-200 mm — never a solvent-based adhesive, which attacks the lacquer from behind.
5. Press the panel home, hold it 1-2 mm clear of the benchtop line, and secure with tape or mechanical clips while the adhesive cures.
6. Tool the perimeter joint with neutral-cure silicone and keep the splashback out of steam and standing water for 24-48 hours.

Common Mistakes We See Every Week

• Measuring before the benchtop is installed — glass cut to a benchtop that later finishes 5 mm higher will not drop in.
• Cutouts sized exactly to the socket plate instead of socket plus clearance, so electricians lever plates against glass edges.
• Ordering white or pastel paint on clear substrate and discovering the green cast only after installation.
• Splitting the order across suppliers or production batches — lacquer batches shift subtly and a butt joint shows it instantly.
• Asking a tradesperson to trim or drill a tempered panel on site; it will shatter, and no manufacturer can rework it.

A Note From the Paint Line

A splashback is the most looked-at panel in a house. We run paint like a color factory: same substrate, same lacquer batch, same oven curve for every panel in one kitchen — or we remake the panel.

Printed and Textured Alternatives to Paint

Back-painting is not the only way to make a splashback a feature. Digital printed glass prints photographic or graphic artwork directly onto the glass face before tempering, opening full-bleed images, marble effects and abstract patterns that paint cannot produce; screen printed glass suits flat solid colors and repeating patterns in volume, with ceramic ink fused into the surface. Both protect the image behind the glass exactly like paint does. For cabinet fronts and open shelving backs, fluted patterned glass remains the fastest-growing choice — texture instead of color.
