• Made from rapidly renewable resources: bio-based soy compounds and modified acrylics
• Safe, non hazardous, non-flammable, low odor, easy to apply
• Provides enhanced porosity on green and mature concrete surfaces.
• Ecologically responsible
• Consistent and uniform etching is achieved for the highest quality decorative stain or specialty coating application
• Effectively cleans and removes sealers, efflorescence, mortar deposits and stains
• Depth of etching is the same as hydrochloric or muriatic acid but with a more uniform etch and much less odor than those volatile acids.
• The unique high-viscous gelled formulation allows maximum flexibility for vertical, horizontal or overhead applications
• The gel consistency also provides better coverage with slower evaporation rate as compared to liquid acid. Liquid acid will naturally flow to the lowest point and will evaporate much more quickly. Inconsistent coverage and dwell time will naturally affect overall uniformity or even the potential of having inadequate porosity that will affect the quality of installation.

Applications

Horizontal and Vertical Surfaces, Green and Mature Concrete, Factory and Warehouse Floors, Concrete Stairways, Aircraft Hanger Floors, Tile Up Concrete, Exposed Vertical or Overhead Concrete, Masonry, Removal of Most Sealers

Surface temperatures should be at 40°F to 100°F (20°C to 32°C). Eco-Etch tm performs effectively at lower temperatures, but the dwell time must be increased.

Preparation:
Ensure that all adjacent surfaces are suitably protected.  Ensure that all areas to be etched are clean, dry and free of oil and grease. DO NOT DILUTE. Pre-wet or protect all areas not be etched which may come in contact with product or rinse water. Apply a thick, even layer of Eco-Etch as determined from your test patch, by brush or decorative/texture roller and fully cover the concrete surface. Etching will begin immediately. Allow 10-15 minutes contact time, then agitate with stiff broom, nylon brush, or back roll surface, to introduce unreacted Eco-Etchtm to the surface. Allow an additional 10-15 minutes contact time. Additional backrolling will increase the depth of the etch. Pressure wash or rinse with water while scrubbing with a stiff brush to neutralize and expose etched concrete surface. Pressure washing is the recommended method of removal.

Dwell Time: The time required to etch concrete depends on the type and age of the concrete. Most concrete will be etched within 30-40 minutes. Rinse the product off as soon as an adequate etch has been achieved.  Longer contact times and additional agitation may be required for removal of sealers. Additional applications and contact time may be required for high strength concrete (above 4000 psi).

Recoating: As with any etching compound, it is advisable to check the pH of the substrate before recoating to ensure that it is compatible with the new coating system to be applied. After sufficient drying time, ensure that the surface is sufficiently dry and dust free prior to recoating in accordance with good painting practice and the coating manufacturer’s instructions.

Removal: For small areas, wiping with a dry cotton cloth, followed by a warm or soapy water rinse can remove residue. For larger surfaces, the majority of the removal can be accomplished by using a nylon bristled push broom or a floor squeegee, then washing the rest with running water through a regular hose.

Eco-Etch can be removed with a mop, however low pressure rinse or mopping does not remove laitance or dust, and therefore scrubbing or dry vacuuming may be required to remove dust prior to recoating.  For best results through a 1500-3000 PSI pressure washer.
