Madewell Permaseal Platinum is a heavy duty, moisture-tolerant epoxy coating product. The installed material resists permeation by water vapor and controls alkalinity to levels acceptable for most coatings, adhesives, and floor covering systems. Permaseal Platinum is designed for use on concrete floors in industrial and commercial construction.

Advantages of Permaseal Platinum:

  • Reduces moisture emission from 25 pounds per 1,000 square feet (or 100% relative humidity) to less than 3 pounds per 1,000 square feet overnight
  • Eliminates issues associated with alkalinity
  • Produces phenomenal adhesion strength
  • May be installed in as soon as three days after placement of the concrete
