SPECIFICATION				2 1/2 TO 1
							Large Joint Filler/ Sautillo Grout

**************************************************************************************
DESCRIPTION: A grouting compound designed to fill large grout joints that are usually associated with terracotta tile, such as Mexican, Brazilian, and Spanish tiles.

Specify for grouting high absorptive tile with joint widths from 3/8” to 3/4” (10mm to 19mm).

Specify for interior or exterior floor and wall installations.

Specify grouting tiles set over exterior grade plywood (interior residential dry floors and countertops only), steel and KERAFONIC sound deadening underlayment, when mixed with PLASTIJOINTS acrylic latex grout additive.

Specify 2 1/2 to 1 Grout with PLASTIJOINTS acrylic latex grout additive instead of water for increased strength, density, flexibility, freeze/thaw resistance and decreased water absorption.

DO NOT specify for joints narrower than 3/8”. Specify ULTRA/COLOR, KERACOLOR WALL or FLOOR, KER 200 or KER 800 grout (see data sheets for details).

DO NOT specify for installations requiring high chemical or acid resistance.  Specify KERAPOXY (see data sheet for details).

DO NOT specify to grout non-vitreous glazed wall tile or polished marble.  Specify KER 800 grout (see data sheet for details).

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.  Prohibit heavy traffic on floors for at least 7 days 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, i.e., low temperatures (60 degrees and under) and high humidity (70% and above) will delay final cure time.
