Sandstone

A clastic sedimentary stone, comprised mainly of silica.

All sandstones have high absorption ratings and medium abrasion resistance ratings; it will stain when exposed to oil and highly-pigmented liquids. Due to its absorbency and mineral make-up, sandstone has a tendency to warp during installation.

Maintenance:

  • Always seal sandstone prior to grouting or use.
  • Always use a grout that is similar in color to the stone to avoid a picture-frame effect.
  • To reduce the appearance of staining, always wipe up spills immediately. Oil and highly-pigmented liquids can penetrate and stain the stone and may need poultice to remove the stain.
  • To prevent warpage, use a rapid setting adhesive such as GraniRapid from Mapei or similar.
