How to use Laticrete NXT Level Flow Self-Leveling Underlayment
- 1Clean the subfloor of dust and loose debris first.
- 2Prime if the product calls for it — most self-levelers and patch compounds need a compatible primer on concrete.
- 3Mix with water to the consistency the bag specifies, using a drill and paddle mixer for a lump-free batch.
- 4Pour or trowel it on, feathering patch compounds to a true zero edge, or spreading self-levelers with a gauge rake.
- 5Let it cure fully per the bag’s schedule before installing your new floor — cure time varies by floor covering type.

FAQ
How do I know if I need a patch compound or a full self-leveling pour?
Small gouges, seams, and low spots (under about 1/4") are a job for a patch/skimcoat compound. A subfloor that’s sloped, or has low spots across a large area, needs a self-leveling underlayment that pours and finds its own level. Ask us if you’re not sure which your floor needs.
How long before I can install flooring over it?
Cure time depends on the product and your new floor covering — check Laticrete NXT Level Flow Self-Leveling Cement-Based Underlayment Grey 50 lb’s bag for the exact window, and always confirm before laying flooring over a fresh pour.
