COLOUR VARIATIONS

Because of its cementitious composition the colour of GRC panels may have different textures and tones within the same panel and / or in comparison to other panels in the same batch. Our colour selection chart is for reference use only and the colours are as close as possible to the original colours.

VERIFICATION OF THE AESTHETIC APPEARANCE

Please check and ensure that you are happy with the delivered product and there are no apparent visible defects. If any issues are detected do not start the installation and contact supplier immediately. No claims will be accepted after tiles have been installed.

DELIVERY AND PACKAGING

• Secure packaging for each tile
• Palletised delivery
• Installation data sheet

CLEANING & MAINTENANCE

• Clean with fresh water and a neutral pH detergent
• Do not use any aggressive cleaning agents or any other chemicals that are reactive to concrete or sealant
• To clean specific stains do not use abrasive materials
• Do not leave standing water on the surface
• Do not leave stains to dry, as they may permanently stain the surface
• For outdoor apply sealant periodically depending on usage
• Sweep or vacuum the surface regularly to remove all dirt and dust

CONSIDERATIONS BEFORE INSTALLING GRC PANELS

• Keep packaged until installation
• Do not force the panels over uneven surfaces
• Always store horizontally
• Do not place loads on the panels
• Level the sub-wall correctly before starting the installation (+/- 2 mm in 3 m)
• GRC panels are not rectified, they can have variations of 0.6%.

INSTALLATION GUIDE – WALLS

• Base: solid flat surface
• There can be no rising or negative humidity
• Verify that the base wall is levelled (+/-2 mm in 3 meters)
• Allow for the perimeter joints and joints against objects from the base

STORAGE

• Panels should be kept in a horizontal way
• Do not leave the panels in a vertical or inclined position or leaning against any surface
• Keep in a dry, clean space in the original packaging

(1) DIRECT WALL INSTALLATION WITH ADHESIVE

TOOLS AND MATERIALS NEEDED

• Spirit Level
• Primer, sealer and Polyurethane / Epoxy adhesive
• Screws and anchors
• Tape measure
• Cradle Caulking Gun
• Ladder /Scaffold tower/ Access platform
• Tile Spacers
• Angle grinder
• Sandpaper
• Paint Tray

STEP BY STEP MANUAL INSTALLATION

• The wall should be levelled (+/-2 mm in 3 meters)
• Sand the wall to remove any loose elements
• Apply primer if needed
• The base has to be firm. Verify with a sharp tool
• Define the way of installation according to the aesthetic wanted
• Begin the installation of the panels from the bottom up
• Apply adhesive as per manufacturer’s recommendations
• Install panels applying pressure until initial grab
• If necessary use T screws on the panels joint to fix them. Once the adhesive is dry remove the screws
• Panels joints can be butted, left with shadow gaps or filled with flexible tile grout
• Seal the panels with Water Based Sealer, POLIFAN PU K14 or acrylic WAX
