Frequently Asked Questions
Concrete Resurrection Surface Prep & Etch is used to clean and etch bare concrete before applying certain stains, sealers, or coatings. It helps remove surface contaminants while opening the pores of the concrete so the next product can properly penetrate or bond.
Use Surface Prep & Etch when your project requires an acid-etched, porous concrete surface before staining, sealing, or coating.
It is especially useful on smooth or tightly finished bare concrete that needs additional porosity.
Always check the preparation instructions for the stain, sealer, or coating you plan to apply next. Some coating systems may require diamond grinding or another form of mechanical preparation instead of acid etching.
Surface Prep & Etch is intended to work on bare concrete. It will not reliably remove paint, coatings, or many existing sealers.
If water beads on the floor instead of soaking in, an existing sealer or coating may still be present. That material should be removed before proceeding with your project.
How do I apply Surface Prep & Etch?
Work in small, manageable sections and apply the properly diluted Surface Prep & Etch evenly across the concrete.
Use an acid-resistant stiff-bristle brush or broom to scrub the solution into the surface and keep the area evenly wet while the product is working.
Do not allow the etching solution to dry on the concrete.
After the concrete has been sufficiently etched, proceed with neutralizing and rinsing the surface.
Do I need to neutralize the concrete after using Surface Prep & Etch?
Yes. After using an acidic etching product, the concrete should be neutralized before applying your stain, sealer, or coating.
Use Concrete Resurrection CR-585 Surface Neutralizer to neutralize the remaining acidity. Thoroughly rinse and clean the concrete afterward to remove residue.
DIY Tip: If you used acid on the concrete, remember: Etch → Neutralize → Rinse → Dry.
How do I know when my concrete is properly etched?
Properly etched concrete should have a clean, slightly textured, porous surface rather than a smooth or polished appearance.
After the floor has been neutralized, rinsed, and dried, you can perform a simple water test. Sprinkle water in several areas of the concrete. The water should soak in and darken the concrete rather than bead on the surface.
If water continues to bead, there may still be a sealer, coating, contaminant, or area that needs additional preparation.
How thoroughly should I rinse after etching?
Rinsing is very important. After neutralizing, rinse the concrete thoroughly with clean water and remove all remaining residue.
The floor should not have a powdery, chalky, or gritty residue when it dries. Additional rinsing may be necessary if residue remains.
Allow the concrete to dry completely before moving on to the next step in your project.
Can I use Surface Prep & Etch instead of diamond grinding?
Not for every project.
Acid etching can be an effective preparation method when the product being applied allows it, but some high-performance coatings require mechanical preparation such as diamond grinding.
Always follow the surface-preparation requirements of the stain, sealer, or coating you are applying next. When that product requires diamond grinding, Surface Prep & Etch should not be used as a substitute.
Can I use Surface Prep & Etch on new concrete?
New concrete should be allowed to cure for the amount of time required by the product you plan to apply afterward.
Before etching, make sure the concrete is free of curing compounds, sealers, construction debris, oil, and other contaminants. Curing compounds and sealers may need to be mechanically removed before the etching solution can properly reach the concrete.
What is the easiest way to remember the prep process?
For a typical DIY acid-etch preparation:
Clean → Etch → Scrub → Neutralize → Rinse Thoroughly → Let Dry Completely
