Historic Restoration


KEIM’s unique mineral silicate finish systems are 100% natural and fully compatible with historic interior and exterior stone, plaster, stucco and masonry. Their special properties help extend the life and splendor of historic structures around the world including iconic skyscrapers, venerable churches and castles, landmark university and school buildings and many U.S. Park Service monuments and historic sites. KEIM systems are frequently part of restorations that are guided by the U.S. Secretary of the Interior’s guidelines for historic restoration.

  • Impervious to sun and weather extremes, won’t ever fade
  • Penetrating, chemically bonds to protect masonry, won’t peel or blister
  • Mineral surfaces “breathe”, won’t trap moisture

Restoration of the Juliette Gordon Low Birthplace, Savannah, GA



Finishes that Last for Decades

Using a combination of potassium and sol silicate, 100% inorganic, mineral pigments and fillers, KEIM offers superior bond strength while maintaining the highest levels of vapor permeability and color stability. Innovation is also part of our history. In 2002, what is now the third generation of mineral silicate paints, revolutionized exterior historic coatings by using a sol-silicate binder. This combination of silica sol and potassium silicate not only provides bonding by silicification to mineral surfaces, but builds strong adhesive forces to previously painted, organic paints. This nanoparticle technology penetrates latex paint films to bond deep within the existing paint system and is the ideal repaint system when existing coatings cannot be removed.
