SPECIFICATION				GRANI/RAPID
Rapid-Curing, Latex Hydraulic Mortar System

**************************************************************************************
DESCRIPTION:  A particularly fast-setting, fast-curing, two component, latex hydraulic mortar for interior and exterior thin-set and medium-bed installation of natural and agglomerated marbles and granite and all kinds of ceramic floor and wall tiles, from impervious porcelain to non-vitreous terracotta, over all types of approved substrates generally encountered in building.  Because of its extraordinarily low shrinkage and quick hydration characteristics, this two- part system allows tiled surfaces to be ready for light traffic after about 3 hours and is completely cured after only 24 hours.  Its excellent bonding and mechanical properties make it resistance to impact, vibration, temperature changes, aging and mild cleaning chemicals (see data sheet for additional information).

	Specify for interior and exterior floor, wall, and ceiling installations.

Specify for rapid retiling of floors and walls that have to be ready for use within a very short time such as supermarkets, factories, hospitals, airports, shopping malls, etc.

Specify for rapid setting of some moisture sensitive dimension stones that specify for rapid setting that is classified as CLASS B by Gabbrielli testing.

Specify for use as a rapid-set, medium-bed mortar for setting large size or high lugged and heavy ribbed-back ceramic tiles and stone.

Specify for installing all types of natural stone, natural marble, (except Rosso Levanto and Negro Marquina marble; or green marble and green granite or heir agglomerates), natural granite, impervious porcelain tile and all other ceramic tile.  For installing white, light colored or translucent marble, specify White GRANI/RAPID.

DO NOT specify for installation of Rosso Levanto and Negro Marquina marble or green marble or granite or their agglomerates.  Specify PLANICRETE W or KERAPOXY.

Warning: marble, granite, and slate are products of nature made from a vast combination of minerals and chemicals which may cause the material to behave or react in a manner beyond our control.  Neither do we have control over any of the materials and processes used in the manufacturing of agglomerates.  Therefore, determine the suitability of all materials before proceeding with the installation.

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

When specifying GRANI/RAPID in the Tile Selection selected – ceramic, mosaic, quarry, paver, slate, marble or granite – add appropriate articles or paragraphs under the applicable PART as indicated

PROTECTION

**************************************************************************************
Select appropriate statements for installation – floor, wall or both.  Delete non-applicable statements.
**************************************************************************************
[Protect floors from general traffic for at least 24  hours after installation.]

[Protect walls from impact, vibration and heavy hammering on adjacent and opposite walls for at least 2 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, i.e., low temperatures (60 degrees and under) and high humidity (70% and above) will delay final cure time.
