FREQUENTLY ASKED QUESTIONS

  Rapid Set LevelFlor is a self-leveling underlayment that can be used to fill low spots and correct unevenness prior to installing tile, carpet, or epoxy coatings.

• Does LevelFlor require a primer or bonding agent?

  Yes. When LevelFlor is placed over a porous substrate trapped air in the substrate migrates to the surface causing pinholes and bubbles. A primer seals the surface of the substrate, reducing or preventing pin holes. Primers can also reduce water loss into the substrate and increase adhesion.

  Rapid Set Acrylic Primer has been specially formulated for best results with LevelFlor and is ideal for most applications. Rapid Set TXP epoxy primers are also compatible and recommended for applications with high moisture vapor transmission up to 20 lbs.

  Rapid Set Acrylic Primer is acceptable for use on concrete substrates that have less than or equal to 5 lbs. of moisture vapor per 1000 sq. ft. in 24 hours and relative humidity less than or equal to 79%. For substrates with greater moisture vapor emission rate or relative humidity, an epoxy primer and/or moisture vapor barrier must be used.
