Acid etching is a common method for preparing concrete floors before applying epoxy coatings. It helps to clean the surface and create a profile that allows the epoxy to adhere better.
Why Acid Etch?
Acid etching is primarily used to:
Clean the concrete surface by removing dirt, grease, and efflorescence.
Create a slightly rough profile on the concrete, which improves the mechanical bond of the epoxy coating.
Open up the pores of the concrete, allowing the epoxy to penetrate and bond more effectively.
How to Acid Etch
While specific instructions may vary based on the product, a general process includes:
Preparation: Clean the floor thoroughly to remove loose debris. Protect surrounding areas that you don't want to etch.
Mixing the Acid: Always follow manufacturer instructions for mixing the acid solution (usually muriatic acid diluted with water). Always add acid to water, never water to acid, to prevent dangerous reactions.
Application: Apply the acid solution evenly over the concrete surface using a plastic watering can or sprayer. The acid will fizz and bubble as it reacts with the concrete.
Scrubbing: Use a stiff-bristle brush to scrub the surface, ensuring the acid penetrates evenly.
Rinsing: Thoroughly rinse the floor with water to remove all acid residue. Neutralize the surface with a baking soda solution if recommended by the acid manufacturer.
Drying: Allow the concrete to dry completely before applying any epoxy coating. This can take several days depending on humidity and ventilation.
Important Considerations
Safety First: Always wear appropriate personal protective equipment (PPE), including gloves, eye protection, and a respirator, when working with acids.
Ventilation: Ensure good ventilation in the work area to disperse fumes.
Disposal: Dispose of acid waste according to local regulations.
Alternative Preparations: For very smooth or previously sealed concrete, mechanical grinding or shot blasting may be more effective than acid etching.
