SPECIFICATION				ULTRA/PLAN
							Self-leveling underlayment

**************************************************************************************
DESCRIPTION: A specially formulated, cementitious self-smoothing, rapidly hardening compound, to be mixed only with water, to level and repair interior floors up to 1/2” (13 mm) thickness per pour.  ULTRA/PLAN can be used over concrete and exterior grade plywood (interior residential dry areas only). May be used over old cutback adhesive when primed with U.P. PRIMER/RAPID (see technical data sheet for additional information.)

Specify for interior use only. 

Specify for leveling and repairing concrete and properly prepared exterior grade plywood sub-floors (interior residential floor and countertop applications in dry areas only) prior to the installation of carpet, resilient flooring, wood parquet, ceramic tile, slate, marble, granite or stone veneer floors.

Specify for leveling and repairing subfloors, up to 1/2” (13mm) thickness in a single lift.  May be feather edged to allow for smooth transitions from one surface to another.

When specifying for leveling over existing ceramic tile, terrazzo and old cutback adhesive-coated floor surfaces, specify U.P. PRIMER/RAPID as a primer to be used in conjunction with the leveling compound (see data sheet for details).

Specify when requiring compatible bonds with resilient or ceramic tile adhesives, dry-set mortars, expoxies and polyurethane adhesives when these materials are subsequently used for the final installation of the floor covering material.

Specify for high traffic areas, including special use situations where wheelchair traffic exists or other point loading exists.

DO NOT specify for exterior applications.  Specify PLANICRETE 50 with a sand/cement-leveling coat (See data sheet for details).

DO NOT specify where hydrostatic conditions exist.

DO NOT specify for spot patching.  Specify LEVEL/PATCH (see data sheet for details).

DO NOT specify over presswood, particleboard, masonite, chipboard, Lauan, gypsum floor patching compounds, metal or similar dimensionally unstable substrates.

When specifying ULTRA/PLAN in the Self-Leveling Underlayment Section selected, add appropriate articles or paragraphs under the PART as indicated.

Provide heated and dry storage facilities on site.

PROJECT CONDITIONS

Maintain environmental conditions and protect work during and after installation to comply with manufacturer’s printed recommendations.

Maintain temperatures at not less than 50 degrees F (10 degrees C) during installation and for 7 days after completions unless higher installation standards are required by referenced installation standards or manufacturer’s written instructions.

PART 2 PRODUCTS

MATERIALS

**************************************************************************************
When specifying ULTRA/PLAN over existing ceramic tile, terrazzo and old cutback adhesive-coated floor surfaces select PRIMER: U.P. PRIMER/RAPID with the UNDERLAYMENT: ULTRA/PLAN.
**************************************************************************************

UNDERLAYMENT: ULTRA/PLAN cement-based self-leveling underlayment, as manufactured by MAPEI CORPORATION.

**************************************************************************************

MIXES

Site mix self-leveling underlayment with water in accordance with manufacturer’s printed instructions.

PART 3 EXECUTION

**************************************************************************************
Specifications for surface conditions are listed in the beginning of the specification of MAPEI’s Architectural Binder.  These specifications should be called out with the related work sections.  Delete non-applicable conditions.  (Refer to ANSI EXPLANATION AND NOTES section: AN-3 RELATED WORK SPECIFIED IN OTHER SECTIONS.)
**************************************************************************************

INSPECTIONS

Verify substrate surface is ready to receive work of this Section.  Do not proceed with work until surfaces and conditions comply with manufacturer’s requirements.

PREPARATION

**************************************************************************************
Select prime statement when adding U.P. Primer/RAPID under PART 2, MATERIALS.
**************************************************************************************
*Prepare substrate in accordance with manufacturer’s printed instructions.

	[Prime substrate in accordance with manufacturer’s printed instructions.]

	INSTALLATION

Install underlayment in accordance with manufacturer’s printed instructions.

**************************************************************************************
No TCA installation method for self-leveling underlayment exists at this time.
**************************************************************************************

Install expansion and control joints in accordance with TCA method EJ171.

PROTECTION

Protect from foot traffic for at least 2 to 3 hours after installation.

Protect from general traffic, dirt and dust from other trades until final floor covering surface has been completely installed.

**************************************************************************************
When dealing with cement-based products, it should be noted that temperature and humidity during and after installation of tile affect final curing time, i.e., low temperatures (60 degrees and under) and high humidity (70% and above) will delay final cure time.
