Floor Underlayment 2132

Product Description

FILL & FINISH is a trowel applied, highly polymer modified, cement-based, rapid setting underlayment. It provides an exceptionally smooth, true “feather finish” to a wide variety of substrates, including wood, concrete, ceramic and existing resilient flooring. FILL & FINISH can also be used indoors to repair damaged concrete wall surfaces and on exterior concrete walls that are to be coated.

FILL & FINISH can be used to create an exceptionally smooth underlayment prior to the installation of floor coverings such as carpet, VCT, sheet vinyl, wood and other flooring surfaces.

Directions for Use

Coverage Rate: Estimating Guide – Approximately 30 sq. ft .at 1/8 in. thickness per 10 lb pail.

Approximately 250-300 sq. ft ./10 lb. pail for skim coating, depending upon the type and porosity of the substrate.

Substrate texture and porosity will influence the actual coverage rate.

NOTE: For horizontal applications, interior use only. Exterior vertical applications must have a protective coating applied. Do not apply at temperatures below 40° F. Do not apply over gypsum-based substrates or water-based adhesives. Do not use as a wear layer.

Prepackaged material segregates while in the pail, thus when mixing less than a full pail it is recommended to first agitate the pail to assure it is blended prior to use.
