Ecologic™ Acrylic Latex Additive

Product Description
Ecologic™ Acrylic Latex Additive is a non-re-emulsifiable, architectural grade, acrylic latex admix for Natural Hydraulic Lime, Portland cement and gypsum-based mixes. Ecologic™ Acrylic Latex Additive has been formulated to enhance performance by improving the bond to masonry, strength, flexibility, adhesion, cohesion, and overall ‘stickiness’ of mortars along with adding more water resistance and a faster speed of curing as properties to enhance specialty mortars.

General Application
Masonry surfaces must first be clean of all traces of curing agents, form release agents, oil, grease, dirt, dust, efflorescence, mold, other biological contaminants.

Masonry surfaces must then be pre-wetted but have no standing water remaining before the application of Ecologic™ Acrylic Latex Additive which is intended to be placed directly onto the substrate. Masonry surfaces must also be pre-wetted but have no standing water remaining before the application of any mixes containing Ecologic™ Acrylic Latex Additive which will then be placed directly onto the masonry.

In all cases after mixing, promptly place Ecologic™ Acrylic Latex Additive modified material with a steel trowel. Do not over trowel. The trowel should be kept clean to avoid pulling. Very little pressure should be used when finishing. Lubricate trowel as needed with the mixing water containing Ecologic™ Acrylic Latex Additive to prevent a “wet drag.” Clean trowels frequently. For Ecologic™ LimeCrete mixes which are used to make Lime Concrete or when placing Portland cement-based concrete mixes, a metal straightedge may be used to screed the mix. A short vibratory stroke while keeping a buildup of material ahead of the screed is encouraged. Wash hands and equipment with water immediately after use.

Coverage
For a 15% dilution to 85% water, one gallon of Ecologic™ Acrylic Latex Additive will produce 6.75 gallons of modified mixing water for lime based mortars. When used as a bonding agent at full strength, one gallon of Ecologic™ Acrylic Latex Additive will cover approximately 250-300 square feet over dense concrete or masonry, or 150-200 square feet over concrete block or brick.

Curing
Ecologic™ Acrylic Latex Additive is self-curing under high dosage conditions; therefore, the need for excessive damp curing is not as necessary for Natural Hydraulic Lime and Natural cement-based mixes containing 20% of Ecologic™ Acrylic Latex Additive to water. Do not use membrane curing compounds or non-breathing blankets to shelter the work. In hot, dry, sunny, or windy conditions cover the work with damp burlap or with plastic to keep rain off the work by sheltering it so that the covers will still allow air to flow underneath the covers. Do not lay the plastic
directly on the work as mottling may occur. The surface of Ecologic™ LimeCrete Floors should be ready for light foot traffic in 48-72 hours and put into standard light-duty service after one week of curing. Portland cement based concrete can receive light foot traffic in 24-48 hours and receive heavy traffic in 96 hours. Allow to cure for 7 days in wet areas such as pools and showers for all applications.
