Level IT Base: Heavy Duty, Deep Fill Smoothing Underlayment

Application

  • When mixed with clean cold water, Level IT BASE is a product that can be trowel or pump applied, to smooth and level, sound and strong internal subfloors prior to applications of Level IT TOP (see relevant technical datasheet sheet) where a wearing surface is required, and prior to applications of Ultra Floor smoothing underlayments when a finished decorative floor covering is being installed.
  • In some applications Level IT BASE can be used as the finished floor prior to application of high build resin coating (consult Ultra Floor technical department).
  • It is a protein free formulation so maybe used in biologically sensitive areas and can be applied to most cementitious subfloors including those incorporating fully commissioned warm water underfloor heating systems.
  • It may also be used over fully cured and dry calcium sulphate screeds.
  • Level IT BASE should be applied at a minimum application thickness of 5 mm and can be applied up to a maximum of 50 mm.
