Is etching concrete necessary?
If the concrete is new or does not have heavy oil contamination it still needs to be etched. The rougher the better. Thin build systems (waterborne epoxy) are best prepped by using a acid etching or diamond grinding. The key here is to open up the pores of the concrete so the epoxy has something to sink into.
What happens if you don’t etch concrete before epoxy?
Acid etching removes laitance, but cannot remove curing compounds or many of the contaminants found in industrial settings, such as oily deposits and water-insoluble materials, any of which can interfere with the adhesion of a coating. Improper surface preparation can result in poor bond and lack of coating adhesion.
Can you seal concrete without etching?
But etching products work only if the concrete is clean and not already coated. You could easily spot paint if the concrete were coated with that, but sealer, which would also keep paint from sticking, might be invisible. One way to test for sealer is to pour on some water.
Should new concrete be etched before sealing?
The short answer is: Yes, even new concrete needs to be etched before applying epoxy or a similar type of garage floor coating. Etching is part of the concrete preparation process. And what many people are not aware, is that proper preparation of the concrete before a coating is applied is the most important part.
Can I just paint my concrete floor?
You can refresh the entire space by painting your concrete floors. In combination with the right tools and techniques, today’s masonry paints, designed specifically for concrete, make it easy to turn a drab concrete floor into an attractive surface that can complement a variety of spaces, both indoors and out.
Does vinegar 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.
Is it worth it to epoxy garage floor?
Is It Worth It To Epoxy Your Garage Floor? Epoxy is durable, easy to clean, and protects the concrete substrate of your garage floor. It is also a highly affordable flooring solution. If you are looking to renovate and protect your garage floor, epoxy is worth it.
Do I need to acid wash concrete before painting?
In most cases, special cleaning and/or etching of the concrete surface will be required before painting, and the appropriate cleaner (often TSP, trisodium phosphate) and etcher (usually a solution of muriatic acid) can be obtained. These chemicals, especially the etcher, must be used with care.
Can you put a second coat of epoxy on garage floor?
Only one coat of EpoxyShield is needed on most concrete floors. If a second coat is needed / desired, it can be applied once the initial coat has dried. For the best adhesion, apply the second coat within 4 days of the first coat.
How long after sealing concrete can you walk on it?
Allow the sealant to fully cure and dry.
It is equally important to allow the sealant to fully cure and dry for at least 24 hours before walking on, driving over, or parking vehicles on the driveway. After the sealant has dried, you will want to inspect the entire driveway to verify there were no spots missed.
How long after etching concrete Can you paint?
Using a mop to apply the acid* does not give a consistent etch. Concrete floors should not be painted for at least 60 days after installation. It takes 30 days for the concrete to cure and a further 30 days for the balance of the moisture to leave the concrete.
How long does concrete need to dry after etching?
After all the water has been removed, the pad should have at least 48 hours of drying time before you apply any etching to the surface. If the weather is particularly humid, wait up to 72 hours for best results.
How many coats of sealer can you put on concrete?
Concrete sealers are best applied in two thin coats. The first coat of sealer acts like a primer. Most of it will disappear into the concrete surface, and the concrete will probably look fairly unattractive after the first coat. The second thin coat will provide an even finish, color enhancement and gloss.
How long does concrete sealer last?
Epoxy and urethane systems last between 5-10 years, closer to 5 if the surface experiences heavy traffic. Reactive penetrating sealers are the longest lasting concrete sealers, wearing away only if the substrate surface itself wears away.
Can I put epoxy over sealed concrete?
Do not attempt to apply epoxy over existing concrete sealers. These need to be removed first as epoxy will not adhere to them. Also, floor paint is not a good base for epoxy and needs to be removed as well.
