Custom Bldg Products LQ50 Self-leveling Underlayment 50 Lb

Product Description

The CUSTOM BLDG PRODUCTS LQ50 is a cement-based, self-leveling floor underlayment designed for fast, accurate surface preparation before finish flooring installation. Mixed with water only, this pourable formula eliminates the need for troweling, allowing installers to achieve a flat, smooth substrate efficiently. At 50 pounds per bag, it is suited for projects requiring consistent coverage across uneven concrete or wood subfloor surfaces. Flooring contractors, tile setters, and general construction trades rely on this type of product to correct minor surface irregularities before installing tile, hardwood, LVP, or other finish materials.

This underlayment is used in residential and light commercial flooring applications where a level substrate is required prior to finish floor installation. It is appropriate for interior use over concrete slabs and prepared wood subfloors. The product is mixed with water only on-site, making it practical for a wide range of job conditions. Prior to application, the manufacturer recommends using Level Quik Concentrated Latex Primer to ensure proper adhesion and performance of the underlayment.

Installation Notes

Installation is typically performed by flooring contractors or tile setters working under applicable building codes. The subfloor must be clean, structurally sound, and properly primed before the underlayment is poured. Mix only with water per the manufacturer instructions and allow full cure time before installing finish flooring materials. Do not apply over surfaces with active moisture intrusion or to exterior areas.
