Treadstone™ Sitemix SL is a unique proprietary formulation technology delivering an aggregate free self-leveling underlayment. Being aggregate free, Sitemix SL provides a lightweight, low-density, high flow leveling underlayment. Meeting load restrictions make Sitemix SL an economical and ideal solution. Sitemix SL achieves a smooth, flat, monolithic surface meeting/exceeding the toughest floor covering requirements. Performance characteristics allow for minimal to no surface prep, simply clean, prime, and pour. Sitemix SL is the ultimate in underlayment performance.
Treadstone™ Sitemix SL is approved for use over fully cured or existing concrete, wood, or other clean structurally sound substrates meeting L/360 deflection criteria.

|Dry Demsity||90 to 100 lb./cu. ft.|
|Recommended Thickness||1/8” to 1” in a single lift, contact Formulated Materials for recommendation|
|Yield||46 sq. ft. at 1/4” depth|
80lb Bags; 49 bags per pallet
2960/2800 lb Supersack
Clean, remove all foreign matter from surface. Surface must be dry. All loose or weak material on substrate must be mechanically removed. Use Treadstone™ recommended primer prior to pour. With new dust regulations it is important not to use oil based floor sweeps, as proper adhesion of the underlayment to the subfloor or finished floor covering to the underlayment will be unachievable.If moisture vapor conditions exist, test to ensure proper MVER limits, not to exceed 5 lbs. per sq. ft. for 24 hours per ASTM F-1869.
Treadstone™ Sitemix SL is to be installed by a trained, licensed Treadstone™ Dealer. The building must be closed in with a minimum of 50 degrees F, maintained for a period of 72 hours during and after the installation of Sitemix SL. Adequate ventilation is required to ensure proper curing, for more information regarding drying conditions contact Formulated Materials or refer to our Recommended Jobsite Conditions Document. Once Sitemix SL is installed and fully cured, use Treadstone™ Surface Sealer prior to the installation of all glue down or thin set floor coverings. Floor covering Manufacturer’s recommendations supersede all others.
Store in dry conditions.
