Spex•Crete™ 350 Ultra Lightweight Underlayment

What Is Spex•Crete™ 350 Ultra Lightweight Underlayment?

Spex•Crete™ 350 ULU is a Ready-To-Mix, just add water, lightweight underlayment that is designed for deep fill flooring applications. Our new and improved system has been designed to increase your project's efficiencies, costs and labor usage. Spex•Crete™ 350 ULU also has an extremely low installed weight of only ~3.0 - 3.5 pounds per square foot at 1"!


If you are not happy with installing foam board on your sub-floors prior to installing your self-leveling overlay, or would like to potentially reduce the labor cost associated with installing your deep fill flooring system, check out Spex•Crete™ 350! 


Spex•Crete™ 350 ULU can be pumped, placed and finished very efficiently and you do not have to worry about that bothersome foam board that is hard to work with and has trouble sticking properly to your sub-floor.
