SPECIFICATION				ULTRA/FLOR
							Medium Bed Dry-Bed Mortar

**************************************************************************************
DESCRIPTION: A medium-bed dry-set mortar for interior and exterior setting of large modular tile, including high lugged tile, brick paver, and dimension stone.  Designed to be used between 3/8” (10mm) and 3/4” (19 mm) thickness to minimize leveling and back buttering and to give better support under the larger tile modules.  (See technical data sheet for additional information.).

Specify for interior and exterior floor installations.

Specify over properly prepared concrete, masonry block, cement mortars or leveling coats, cementitious backer units and gypsum wallboard.

Specify for installing large size or high lugged and heavy ribbed-back ceramic tiles, monocottura, brick paver, marble, dimension and natural stone tile.

Specify ULTRA/FLOR with KERAPLY for improved performance over concrete when installing impervious porcelain-type tiles and for interior installation over exterior grade plywood.  (See data sheets for details.)

Specify ULTRA/FLOR with KERAPLY for installation of large size impervious tiles and natural slate.  (See data sheet for details.) 

DO NOT specify for installing light colored and translucent marble and their agglomerates, specify white GRANI/RAPID or white KERAQUICK M..  (See data sheets for details.)

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

When specifying ULTRA/FLOR in the Tile Section selected – ceramic, quarry, paver, marble or dimensional stone – add appropriate articles or paragraphs under the applicable PART as indicated.

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.)
**************************************************************************************

EXAMINATION

Examine surfaces to receive tile work and conditions under which tile will be installed.  Do not proceed with tile work until surfaces and conditions comply with requirements indicated in referenced tile installation standard and manufacturer’s printed instructions.

INSTALLATION

Install tile in accordance with manufacturer’s printed instructions and ANSI A108.5.

**************************************************************************************
There are TCA methods directly specifying application of medium bed dry-set mortars.  Substitute ULTRA/FLOR where traditional dry-set mortars have been specified.

Select TCA method to be used and delete non-applicable methods.  (Select from latest edition of the TCA Handbook.)

PROTECTION

**************************************************************************************
Select appropriate statements for installation – floor, wall or both.  Delete non-applicable statements.
**************************************************************************************
[Protect floors from general traffic for at least 72 hours after installation.  Plywood or stepping boards may be used after 24 hours when occasional stepping on the floor is unavoidable.]

[Protect walls from impact, vibration and heavy hammering on adjacent and opposite walls for at least 14 days after installation.]

Protect from freezing and total water immersion for at least 21 days after installation.

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