How clean should floor be before epoxy?
The floor must be thoroughly cleaned. Any grease, oil, or dirt left on the floor will prevent the epoxy resin from bonding with the concrete. Once clean, the floor must also be given enough time to dry. A damp floor, just like a dirty floor, creates a surface that the resin can’t adhere to.
How do you prepare concrete for epoxy?
To finish preparing an uncoated concrete floor, you need to etch, acid wash or grind the floor, as a smooth floor will not allow the epoxy to adhere well. You can rent a sand blaster or diamond grinder and rough up the surface. Or you can etch, or acid wash, the floor using a product designed for concrete floor prep.
Do you need to grind new concrete before epoxy?
However, for larger commercial jobs, older concrete, or worn floors we always recommend grinding before epoxy installation. The concrete floor will fail if the coating doesn’t bond mechanically to the concrete floor, so the preparation is the most important part before applying any type of epoxy!Feb 18, 2019.
How long after pressure washing concrete can you epoxy?
We highly suggest 45 or more days of curing (depending upon weather conditions). Faster curing concrete can be used, but discuss it with Stronghold Floors staff first.
What happens if you don’t etch concrete before epoxy?
In Closing. New concrete must be etched before applying the epoxy. The smooth surface of unaltered concrete won’t bind with other materials, such as epoxy or paint. As a result, epoxy will peel and lift away, failing to adhere to the surface.
What do you clean concrete with before painting?

What are the disadvantages of epoxy flooring?
Disadvantages epoxy floor Epoxy floors are hard and therefore there is contact noise during walking. Without underfloor heating an epoxy floor feels somewhat cold, similar to tiled floors. If there are unevennesses or cracks in the substrate, ripples can become visible in the floor.

Can you put epoxy on new concrete?
New concrete can restrict penetration of epoxy even more than older concrete does. The reason for this is that the surface has been freshly troweled smooth. This creates even less mechanical grip and access to the pores at the surface. Concrete surface profiles are often referred to in the industry as CSP.
Can you use vinegar to etch concrete?
Etching – Vinegar’s ability to dissolve CaCO3 will dull your marble, travertine, concrete and terrazzo surfaces. It may “clean” the surface but it is also dissolving pits into the finish and effectively dulling it. This will affect marble, travertine, concrete and concrete terrazzo surfaces.
Do you really need to etch concrete before painting?
Etching is a crucial step in preparing concrete for painting. It gives the surface tooth to adhere to, so your paint is more likely to stick for a long time. Most concrete paints require etching and if they don’t, do it anyway. Don’t skip this step if you want a long-lasting painted concrete floor.

Can I sand concrete instead of etching?
Yes, you will need to grind in order to remove the sealer at the surface and provide a proper profile for the coating. You cannot acid etch. The reason is that the sealer prevents the acid from reacting with the minerals in the concrete since the concrete is sealed.
How do I acid wash concrete?
The acid is mixed in a 5 gallon plastic pail – 3 or 4 parts water to 1 part acid. The strength of the solution is determined by the condition of the concrete. Very hard, smooth or shiny concrete will require a stronger solution. The acid solution is poured into a sprinkling can and then onto the surface.

Do I need to acid wash concrete before painting?
Acid wash is also known as etching, which is an essential process for concrete surfaces that are going to be painted. Not only does paint stick better to a porous surface, but acid washing helps to reduce the alkalinity and moisture levels of a surface, which also helps the paint adhere and stay adhered to for longer.
How do you clean a concrete basement floor before painting?
Clean the Floor After vacuuming, mop the floor with detergent and water, then rinse with clear water to remove fine dust. Dry any visible wet spots with a towel, then let the floor dry for a full 24 hours with a dehumidifier or fan running. The floor must be completely dry before painting.
