Waterproof Wall Panels
100% waterproof decorative wall panels with an SPC core — 147 decors across nine surface families, in 3.6–5.0 mm thicknesses up to 3200 mm long.
100% waterproof decorative wall panels
INNOMASTER waterproof wall panels are made by plasticating and extruding PVC resin with stone powder into a Stone Plastic Composite (SPC) core — no adhesives, no heavy metals, no formaldehyde, and 100% waterproof. Surfaces are sealed with electron beam curing (above 99% cure degree) and printed with 147 decors across nine surface families, from muted tones and wood grain to marble, gemstone, and artistic accents. The direct-bond installation method eliminates grout lines, mold, and demolition. Typical applications are wet areas in hotels, healthcare facilities, and commercial interiors — bathrooms, shower walls, and wet rooms installed over sound substrates without demolition.

Stone-Plastic Composite, from two simple ingredients
PVC resin and stone powder, plasticated and extruded into one stable board — no adhesives, no heavy metals, no formaldehyde.
Why choose waterproof SPC wall panels
100% waterproof — the stone-based core absorbs no moisture
Formaldehyde-free: plastication and extrusion, no adhesives, no heavy metals
Mold-resistant surface that does not absorb moisture
Cost-effective alternative to natural stone, ceramic tile, and slate
Dimensionally stable core resists expansion and contraction
EB-cured surface above 99% cure degree — stain-proof and scratch-proof

Common questions
Yes. The stone-based SPC core absorbs no moisture, so the panels are 100% waterproof and mold-resistant — specified for bathrooms, wet rooms, hotel bathrooms, and healthcare environments, with EB-cured surfaces that resist stains and scratches.
147 decors across nine surface families — muted tones, wood grain, fabric, sandstone, concrete, terrazzo, marble, gemstone, and artistic accents — in DSPC, DSPC-A, DSPC-T, ESPC, and PSPC structures. Panels run 1210 × 2450–3200 mm at 3.6–5.0 mm thick; the 5.0 mm board joins grout-free with lock splicing.
No. The SPC core is made by plasticating and extruding PVC resin with stone powder — no adhesives, no heavy metals, no formaldehyde. The panels hold French A+ VOC, ROHS, CE, and ISO 14001 certifications.
Direct-bond installation: structural adhesive bonds the panels over existing tile, plaster, concrete, or plasterboard — no demolition and no grout lines. Bathrooms and wet areas are typically completed in hours rather than days.
