Installation Guideline

Substrate preparation

In order to achieve good adhesive bond, be sure to identify any surface contaminants that may be present and remove. Island Stone Stacked pebble is app 35kgs per sq m installed and in some instances may require structural angle support depending on the height of structure total weight loading etc, discuss with engineer.


Synthetic resin based waterproofing in water dispersion.


As required for interior or exterior applications.


Use a tile adhesive with no vertical slump.


Island stone recommends silica sand and cement with a grout additive for flexibility and improved adhesion. We’ve found that natural grey colour gives the best results.

Grout Coverage

Apply approximately 4 kilograms of silica sand and cement per square meter.

Installing the Stone

  • Tiles should be brick stacked to give maximum effect 
  • Ensure pebbles lines run even and parallel by marking the substrate or running a chalk line every 300mm 
  • Press tile firmly into tile set by hand and then with rubber backed grouting tool ensuring full contact adhesive and that the pebble is vertical to the substrate.

Pre Grout Sealing

To ensure the best possible installation an appropriate penetrating sealer should be applied as a grout release prior to grouting.


First, apply silica sand and cement grout with rubber backed grouting tool 

  • Allow grout to dry to a granulated stage.
  • Brush grout out to required depth with a firm bristled broom or brush (Note: bristle firmness will be determined by grout setting time.) 
  • Final brushing with a soft broom and water if required. 
  • Remove cement film after setting with firm brush or chemical grout film remover.

Final Sealing (if required)

  • Penetrating stone sealer. Ensuring compatibility with the pre grout sealer. 
  • Stone enhancement sealer. Ensuring compatibility with pre grout sealer
