Indoor use only. Nroro wall panels are for interior walls and ceilings — not for outdoor use or areas exposed to weather.

1. Before you start

Store the boxes flat, indoors, in the room where the panels will go. Do not stand boxes on end.
Check every panel for color and surface defects before you fix it. Installed panels with visible defects are not covered.
Panels from different boxes can vary slightly — mix boxes across the wall.
Order a few extra panels for cuts and corners.

2. Tools

Tape measure or laser measure, level, pencil, fine-tooth saw or miter saw, utility knife, drill/driver with screws, nail gun (brad or staple) for the clips, construction adhesive for trims, safety glasses and gloves.

3. Prepare the wall

Plaster or drywall: the wall must be solid, dry and flat. Fix the panels and clips directly to the wall or into studs.
Brick, block or concrete that is not plastered or not flat: fix horizontal furring strips (wood battens) or a light steel frame to the wall first, level and in one plane, then fix the panels to the strips.
Ceilings: fix the panels to a level frame (battens or steel channel) and finish the edge against the wall with a cornice or edge trim.
Mark any outlets, switches and fixtures before you start.

4. Install

Measure the wall and plan the layout so the cut panels at both ends are similar in width.
Mark the position of the first panel and check it is plumb (vertical) with a level. Every following panel takes its line from this one.
Fix the first panel to the wall or frame with a screw at its starting edge.
Hook a fixing clip onto the panel edge and fasten the clip to the wall or frame with the nail gun or a screw. Repeat along the full length of the panel.
Slide the tongue of the next panel fully into the groove of the fixed panel, then clip and fasten its free edge the same way.
Repeat until the wall is covered. Cut the last panel to width with a fine-tooth saw.
Finish outside corners, inside corners and panel ends with the matching Nroro trims, bonded with construction adhesive.

5. Slat panels — matching trims

Outside (positive) corner trim for external corners.
Inside (negative) corner trim for internal corners.
Railing trim for exposed top or side edges.

Each trim is made in the panel color. Order trims with the panels.

6. Care

Wipe with a soft damp cloth. For marks, use a mild neutral cleaner, then wipe with clean water.
Do not use abrasive pads, solvents or strong chemical cleaners.
Keep panels away from direct heat sources such as heaters, stoves and fireplaces.
