Xtreme Hard™ is a highly reactive Colloidal Silica-based
densifying agent. The Colloidal Silica molecule has more reactive sites, so it
goes to work quickly, within 1-2 minutes. Spray it on the concrete until the
surface is saturated, then agitate with a soft bristle broom. Wait until
dry (45-60mins).
Xtreme Hard™ is a green, clean and
safe material. Its low pH formula (pH approx 8.7, only slightly higher than
baking soda) is safer for you to handle. Xtreme Hard emits no Volatile Organic
Compounds (VOCs) and eliminates the hazardous-material disposal, so it’s better
for the job site and friendlier to the planet. Xtreme Hard is shipped as
a concentrate. One gallon of concentrate makes five gallons of ready-to-use
product. Xtreme Hard is the lowest cost densifier per square foot. New Improved
Nano Technology Formula, penetrates deeper into the concrete.
Coverage: 32 ounces of concentrate makes 1 gallon of ready-to-use product which will cover 400-600 Square Feet. Just add water.
