Custom Building Products Lq50 Levelquik Self-leveling Underlayment, Cement-based, 50 Lb.

LevelQuik LQ50 is a cement-based, self-leveling underlayment designed to create a smooth, even foundation before installing ceramic tile, natural stone, resilient flooring, carpet, wood, parquet, or other floor coverings. This pour-and-flow formula transforms uneven subfloors into a professional-grade base without extensive troweling or manual labor, making it ideal for both residential and commercial flooring projects.

Whether you're preparing concrete, cement backer board, sheet vinyl, PVC, concrete terrazzo, or stone surfaces, LevelQuik LQ50 eliminates the time-consuming process of leveling by hand. Simply mix with water, pour over low spots, and let it self-level to create a crack-resistant, durable substrate. The product's rapid-dry chemistry and controlled-cure technology prevent common installation problems such as bond failure, crumbling, mildew, and staining of resilient flooring caused by free moisture.
