Product Details

CitrusEtch™ is a premium concrete etcher designed to expertly open the pores of concrete surfaces. This ensures optimal penetration of coatings, facilitating a strong and durable bond. Trust CitrusEtch™ for a seamless and lasting finish on all your concrete projects.

Quick Facts

Application Tools: Best applied using a pump sprayer (filter removed). Spiked shoes are highly recommended.
Location: Suitable for both interior and exterior surfaces, including garages and driveways.
Processing Time: 15 minutes, ensuring surface stays wet to avoid difficult-to-remove residue.
Neutralization: Use ProClean Neutralizer™ for effective neutralization after etching.
Coverage: Approximately 200 sq. ft. per gallon of solution. Actual coverage may vary based on surface porosity and texture.
Application Temperature: Optimal between 40°F-95°F (5°C-35°C).
Recommended Uses: Ideal for preparing smooth concrete floors for coating.

How-To Guide

Preliminary Testing

Before using the product for your entire project, try it out on a small, hidden area of the surface you'll be working on. This will let you see how it looks and if it's the right fit for your project.

Product Dilution

CitrusEtch™ must be diluted with water before application. The dilution rate varies by packet size:

3-Ounce Packet Mix with 1 quart (0.95 liters) of water
10-Ounce Packet Mix with 1 gallon (3.79 liters) of water
50-Ounce Packet Mix with 5 gallons (18.93 liters) of water

Application

Surface Preparation:

  • Cleaning: Ensure the concrete surface is free of oil, grease, contaminants, sealers, and curing compounds. A clean surface is critical for effective etching.
  • Pre-Test: Conduct a small area test to determine the appropriate concentration and dwell time, typically 15-20 minutes, adjusting for specific surface conditions.

Etching Solution Application:

  • Sprayer Setup: Remove filters from an all-plastic pump-up sprayer and fill with the CitrusEtch™ solution at the specified dilution rate. Hand showing filter removal from a pump-up sprayer
  • Application: Apply the solution evenly across the surface, avoiding pooling and ensuring the surface does not dry during the application. Maintain the solution on the surface for a dwell time of 15 minutes.
  • IMPORTANT: Wear spiked shoes to prevent shoe prints etched into concrete. Illustration of the importance of wearing spiked shoes during application to avoid leaving permanent shoe prints in wet concrete.

Neutralization and Cleanup:

  • Neutralization: Post-etching, prepare and apply ProClean Neutralizer™ using a similar sprayer setup. Ensure even coverage and maintain wetness for 15 minutes.
  • Scrubbing: Manually scrub the treated area or use a low-speed floor buffer with a brush attachment for residue removal.
  • Residue Removal: Employ a wet-dry vacuum for optimal residue removal. A cotton mop is an alternative but less effective.
  • Rinsing: Thoroughly rinse the surface multiple times to remove any lingering solution, preventing white powdery residue, which could hinder the adhesion of future coatings.
  • Texture Check: After you neutralize and rinse, the right surface should feel a bit rough, like very fine sandpaper. If it still feels smooth, doesn't soak up water in 3 to 5 minutes, or if it seems rough only because of a powdery coating, you need to do the etching, neutralizing, and rinsing steps again.

Concrete Etching Tips

  • Prevent Splashes: Cover everything you don't want etched with plastic sheets.
  • Maintain Wetness: Do not let CitrusEtch™ dry on the surface during etching. If the solution dries, it can leave behind a stubborn residue that requires extensive scrubbing to remove. Keep the area moist throughout the etching process.
  • Dry the Floor Well: The floor must be dry before you seal it. Fans can speed up drying. The surface might look dry, but moisture can still be in the concrete and affect the sealer.
  • Correcting Shoe Prints: In case shoe prints get etched into the concrete, they can be removed by renting a grinder to smooth out the affected areas. Removing shoe prints etched into concrete is challenging. We strongly advise wearing spiked shoes to avoid this issue.

Coverage

Estimated coverage is around 200 square feet per gallon of solution, varying with surface conditions and application methods.

Clean-Up

For cleaning tools and equipment use ProClean Neutralizer™ solution.

Disposal

Dispose of unused product according to local environmental or hazardous waste regulations.

Shelf Life and Storage

Store CitrusEtch™ in a cool, dry place. If unopened and stored properly, its shelf life is approximately 3 years. Avoid extreme conditions.
