Tradeline Sandstone Grey Matte MDF Wet Wall Panel – Tongue & Groove, 2420 x 580 x 11mm

Bring a soft grey sandstone effect to your bathroom with the Tradeline Sandstone Grey wet wall panel. This half-width 580mm tongue & groove panel is the piece that finishes a job properly — sized for window reveals, pillars, narrow alcoves and completing a run where a full panel would need cutting down and wasting most of the board.

Why panels instead of tiles

• No grout. Nothing to discolour, crack or scrub — the single biggest maintenance complaint in a tiled bathroom simply doesn't exist
• Far quicker to fit. A shower enclosure is typically a single day rather than several
• Goes over existing tiles. No hacking off, no skip, no re-plastering, provided the existing tiles are sound and firmly bonded
• Hygienic. The non-porous laminate surface gives mould and bacteria nothing to hold on to
• Wipes clean with a damp cloth and mild detergent

Product Details

Tongue & groove – what that means for fitting

Tongue & groove panels slot directly into one another, giving a near-invisible joint with no trim needed between panels. That is the main reason to choose T&G over square edge. You will still need end caps and corner trims where the run starts, stops or turns a corner — but no H-sections, which are for square edge panels only.

How many do I need?

At 580mm wide this is a filler and detail panel rather than a main wall covering. Most installations use one or two alongside full-width panels — measure the reveal, pillar or leftover width you need to cover and order accordingly.

Fitting notes

• The wall must be sound, dry, flat and free of dust, grease and loose material
• Panels can be fitted directly over existing tiles provided the tiles are firmly bonded and degreased
• Apply panel adhesive in vertical beads, so any moisture behind the panel can drain rather than pool
• Seal every cut edge. The MDF core is exposed wherever you cut, and that is where water gets in. This is the single most common cause of panel failure
• Cut with a fine-tooth blade, face up, to avoid chipping the laminate surface
• Allow the panel to acclimatise in the room for 24 hours before fitting
• Finish visible junctions with Topseal colour-match sealant rather than a standard white silicone
