Stone flooring is being considered for an infusion area of a cancer center. Among the issues being decided (thickness and setting, joint thickness) is an appropriate sealer to protect against the chemicals being used. Without knowing specifically what chemicals, has anyone had experience with sealers for stone floors? There are so many products/manufacturers out there - it would be easy to just throw a virtual dart at the list, but I don't think that's a very responsible way to choose (plus, I might hurt someone - those virtual darts can be dangerous). Anybody have a favorite manufacturer? |

May I recommend the use of W. R. Meadows Sealtight VOCOMP-25 for your floor if it is interior or Sealtight Expo-Gloss for exterior. Look them up at http://www.wrmeadows.com both will work nicely for you and can be found anywhere a Sealtight distributor are. |

W.R. Meadows products are film-forming, sheen-altering products that are intended for concrete and NOT specifically intended for stone. I'd suggest ProSoCo, although some of their product formulations are not Calif-compliant. |

I have specified Miracle Sealant company's Impregnator 511 as a sealer for natural stone when I don't want to alter the appearance.

It works well with ordinary traffic soil and cleaning. I don't know if it would handle the various chemicals anticipated in your particular application. |

One thing that I forgot to mention was the need to be careful about slip-resistance. Depending on finish texture of stone, and specific type of sealer, one could possibly "enhance" slip/fall tendency. If you really want to "shift responsibility to the GC", then spec a "performance" requirement for a slip coefficient consistent with ADAAG "recommendations" (Appendix) AND a non appearance-altering sealer (if like most designers, alteration of surface appearance is not acceptable). |

Dear Anonymous: Your right about the W. R. Meadows products being film forming which is what you need for concrete. I just know from 25 years of experience that some of their sealers have been used and have preformed well certain types of stone. They have a new sealer on the market called Sealtight Decra-Seal that was formulated for decorative concrete, that is non-yellowing high solids acrylic based product that has a built in slip resistance additive, that is VOC compliant. I know it works well on stone because my exposed aggregate driveway was a test section that has been down for 1 year without any problems. They are just now introducing it to the market, and their head chemist said it would well with stone. |
