strata installation & maintenance guide


  • With the Strata Linea collection you will find a polished surface rich with color variation due to the striations and diverse range of tones found in each stone.
  • We recommend ordering 15% overage.
  • Dust and residue from shipping should be cleaned prior to installing.


  • We strongly recommend having a professional with natural stone installation experience install your tile.
  • Before installing, layout your tile and blend so that variations in color and veining are where you would like them to be throughout the installation.
  • Laying out strata tile is similar to hardwood. Group by color and then mix as you go. We recommend a dry layout first to make sure you have exactly the layout you desire. Layout options could be random, or a color gradation across a floor.
  • Refer to the current edition of the TCNA Handbook for detailed installation methods for your project’s needs.


  • clé ONLY recommends the use of Miracle 511 Porous Plus for an invisible sealant finish.
  • Natural stone should be sealed before and after grouting to maintain their appearance and avoid staining. Please consult with your natural stone installer on what sealing methods are best for your installation.
  • In wet areas (backsplashes and showers) both tiles and grouted areas must be sealed as the final step of installation.
  • Always test sealers in a small area to ensure it provides the finish you prefer.
  • If water beads up on the surface of the tile after they have been sealed according to manufacturer’s instructions, your tiles are properly sealed.
  • For applications in wet areas, specific waterproofing precautions need to be taken such as using a waterproof membrane under the tile and use of miracle 511 porous plus.
  • Single coat reapplication of the penetrating sealant is required once a year in shower applications due to the continuous exposure to water.
  • If your contractor is having any issues or questions regarding this sealant, please have them reach out to Miracle tech support directly at 1-877-385-8155 as they are the best and fastest line of resolution.


  • clé ONLY recommends Mapei Flexcolor CQ grout to reduce the risk of grout haze and staining. Make sure to always follow the manufacturer’s instructions. Letting the grout sit for even a short period of time can be problematic.
  • Use of any other grout types can result in installation issues.
  • For natural stone, a wide grout joint is not recommended as it will disrupt the variation and flow of tile color, veining and patterns.
  • Recommended grout joint size – 1/16”
  • We recommend bamboo for grout color.
  • If your contractor is having any issues or questions regarding this grout, please reach out to Maipei tech support directly at 1-800-992-6273 as they are the best and fastest line of resolution.


  • Staining is only a problem when using a grout other than Mapei Flexcolor CQ grout.
  • Should your contractor choose to use another brand of grout other than Mapei Flexcolor CQ, be aware that the dyes used to pigment most grouts will stain the tile.
  • If your contractor opts to use a different grout or sealant brand we are not able to provide advice on failures.
  • Important: During grout application, immediately remove any excess grout off the face of the tile with a clean, damp cloth/sponge. If grout is allowed to cure on the face of the tile it could cause grout haze and staining due to the porous nature of the tile.


  • Over time, a natural patina will occur on floors as it is maintained and naturally wears.
  • Topical sealants will require periodic stripping and resealing - please refer to a professional for this.
  • Single coat reapplication of the penetrating sealant is required once a year in shower applications due to the continuous exposure to water. 
  • Check with the Miracle Sealant tech support directly at 1-877-385-8155 for best advice on maintaining sealants.


  • The natural stones that make up the strata collection (marble, limestone, travertine, etc.) are chemically sensitive so only mild pH neutral cleaners should be used.
  • As with any finely decorated stone product, clé discourages the use of any surface cleansers or scrubbing pads. Cleaning stone requires only mild soap, water and soft cloths.
  • Soapless cleaners are preferred because they minimize streaks and film.
  • Mild, phosphate-free, biodegradable liquid dishwashing soaps or powders or stone soaps are acceptable if rinsing is thorough.
  • Always avoid harsh chemicals and acidic or alkaline cleaning products.
  • Showers and baths: soap scum can be minimized by using a squeegee after each use and using liquid as opposed to bar soaps.
  • Vacuum or sweep regularly – abrasive dirt and materials can scratch the surface.
  • Non-slip mats or area rugs should be placed inside and outside entrance ways to remove abrasive materials that can scratch and dirty the tile surface. Sand, dirt, and grit do the most damage to natural stone surfaces due to their abrasiveness.
  • Dust mop interior floors frequently using a clean, non-treated dry dust mop.
  • Interior wall installations can be cleaned with warm water and damp microfiber cloth.
  • Grout lines can be cleaned with warm water and a nonmetal bristled cleaning brush.
