Dayton Superior LeveLayer Self-Leveling Underlayment

Dayton Superior LeveLayer is a cement-based, nonshrink, self-leveling interior underlayment. Mix with water, pour or pump, and it seeks its own level to a smooth, hard subfloor. Floor coverings typically go down in 14-16 hours. Place from a feathered edge up to 2 in neat; deeper pours take clean pea gravel. Prime first with J42. 50-55 sq ft per 50 lb bag at 1/8 in. Not a wearing surface.

Key Features

  • Cement-based, not gypsum, for interior subfloors.
  • Pour or pump; it seeks its own level.

  • Featheredge to 2 in neat; extend deeper with pea gravel.

Frequently Asked Questions

Is LeveLayer a wear surface?
No. It is an underlayment. Cover it with the specified floor covering.

Do I have to prime?
Yes. Use Level Primer J42 (or J42RTU) so the pour bonds and pinholes stay down.

How thick can I go?
Featheredge to 2 in neat. Over 2 in, Dayton calls for clean pea gravel per the TDS.

When can I cover it?
Typically 14-16 hours, depending on thickness and site conditions. Confirm moisture for the covering manufacturer.
