Custom Bldg Products AMA2 Mortar Admix 2.5 Gallon

Product Description

The CUSTOM BLDG PRODUCTS AMA2 is a pre-mixed liquid polymer admix designed to replace water in cement mortar beds, non-modified thin set mortars, and cement-based grouts. Each container holds 2.5 gallons and requires no diluting before use. Adding this admix to standard cementitious mixes boosts water resistance, shock resistance, and freeze-thaw performance — critical properties for tile, stone, and masonry installations in demanding environments. It is used by tile setters, masons, and flooring contractors who need to upgrade the performance of non-modified materials without switching to a pre-modified product.

The AMA2 is applied in residential and commercial settings wherever non-modified thin set mortar or cement-based grout is being mixed. It is especially useful when setting dense tile formats or working over hard-to-bond substrates where a standard water mix would yield inadequate adhesion or durability. The liquid polymer integrates directly into the dry mix at the job site, giving installers control over the final mix ratio while improving overall working characteristics and open time consistency.

Compatibility

Designed for use with non-modified thin set mortars and cement-based grouts in tile, stone, and masonry installation applications.

Installation Notes

Installation should be performed by a qualified tile setter or mason familiar with cementitious mortar systems. Power down any adjacent electrical circuits and ensure the work area is dry before mixing. Follow the mortar or grout manufacturer's recommended liquid-to-powder ratio when substituting this admix for water. Do not add additional water after the admix has been incorporated into the mix.
