Custom Bldg Products LQESL50 Self Leveling Underlayment

Product Description

The CUSTOM BLDG PRODUCTS LQESL50 is a self-leveling underlayment designed to flatten and smooth subfloor surfaces before tile, stone, hardwood, or resilient flooring installation. Sold as a 50-pound bag, this extended-set formula provides up to 30 minutes of working time, giving installers the flexibility to spread and adjust the material across larger areas before it begins to set. It feathers down to a zero edge and builds up to 0.5 inches thick in a single pour. Flooring contractors and tile setters rely on this product for residential and commercial subfloor prep work where a flat, level surface is required by the finish floor manufacturer.

This underlayment is suited for interior subfloor leveling applications in both residential and light commercial settings. It works over concrete, plywood, and other structurally sound substrates. The extended working time makes it a practical choice for larger pours or when working conditions require additional time for placement and gauging. Installers typically use it ahead of ceramic tile, porcelain tile, natural stone, and resilient flooring systems where substrate flatness tolerances are tight.

Installation Notes

Installation is typically performed by flooring contractors or tile setters familiar with surface preparation standards. The substrate must be clean, structurally sound, and primed per the manufacturer mixing and application guidelines before pouring. Allow full cure before installing finish flooring. Always follow applicable industry standards such as ANSI A108 for tile installation substrate requirements.
