Yes there are certain kinds of epoxies that can be applied over SOME sealed floors. It depends on what type of sealer was used first. They tend to not bond well with some solvent sealers, but water based ones will work. You just have to use the right epoxy primer so it will bond
Generally no. Most stains must absorb into the concrete. If the stain just sits on top of the sealer then it will likely wear away.
You must remove the old epoxy coating before pouring the new floor, for otherwise there will be no bonding. If the epoxy coating is thin (e.g, paint) then it may be possible to remove it by hand sanding. If it is a thick coating, then sandblasting is probably the best method. In either case, appropriate dustmasks and other safety precautions are essential. Good luck
If the crack is large, you'll have to get some more concrete and use it to fill the crack. If the crack is small, you may be able to simply patch it. If you plan on coating the floor with some type of epoxy floor coating, you may be able to simply leave the cracks alone before application, simply allowing the epoxy material to fill the cracks. The work will still come out evenly and the epoxy will actually hide the spot where the crack was once located.
I spoke to the one paint dealer I have confidence in and was told yes I can do exactly that i.e. put a latex (not sure about alkyd) two part epoxy coating over my concrete latex floor paint. First I sanded the surface to get a better bond and my next move is to clean the floor. As a suggestion be sure you have a concrete paint on the floor. If not you could have other problems which I encountered originally i.e. paint not adherring to the concrete in the presence of water. USE ARMORGUARD EPOXY FLOOR COATING, It will last forever, its 100% Solid, No fillers, ODORLESS and NON TOXIC, Its also made with MICROBAN to prevent mold, mildew or algae, look on www.ecosmartepoxysystems.com for more information
If you understand that concrete is a porous material that absorbs and has moisture in it, you then should also understand that this moisture will move toward the top surface of a concrete floor. This moisture will promote mold growth and will also destroy the bond of of most adhesives. Membrane coatings are prone to failure when this moisture carries alkali in concrete to the surface. You are much better off using a penetrating sealer such as "StableCrete" to waterproof the concrete. This product penetrates to form a solid in the capillary/gel-pore system of a concrete. This stops moisture migration and provides for a superior bond to the concrete.
The best moisture barrier for a concrete floor is a high-quality epoxy coating or a polyurethane sealer. These products create a protective layer that prevents moisture from seeping into the concrete, helping to maintain the integrity and longevity of the floor.
You don't normally need sealer over epoxy, but the colour chips may be a reason to. I would check the can for comments on this.
Using epoxy on a concrete floor provides benefits such as increased durability, resistance to stains and chemicals, easy maintenance, and improved aesthetics.
The most popular options for concrete floor finishes are epoxy coatings, polished concrete, and stained concrete.
To refinish your garage floor for a better look and durability, start by cleaning the surface thoroughly. Then, apply a concrete sealer or epoxy coating to protect and enhance the appearance of the floor. Make sure to follow the manufacturer's instructions for the best results.
A high-quality epoxy-based concrete patch is often recommended for repairing damaged areas in a concrete floor. Epoxy fillers are durable, strong, and can effectively bond with the existing concrete surface, providing a long-lasting repair solution.
Epoxy concrete floor paint provides increased durability and aesthetics to concrete floors. It creates a strong, protective layer that resists stains, chemicals, and wear. Additionally, it enhances the appearance of the floor with a glossy finish and can be customized with various colors and patterns.
To refinish a concrete floor effectively, follow these steps: Clean the floor thoroughly to remove dirt and debris. Repair any cracks or damage in the concrete. Etch the surface with a concrete etching solution to ensure proper adhesion of the new finish. Apply a concrete sealer or primer to create a smooth base for the new finish. Apply the desired finish, such as epoxy or stain, following the manufacturer's instructions. Allow the finish to dry completely before using the floor.
To effectively seal a basement floor and prevent moisture and water damage, you can use a concrete sealer or epoxy coating. First, clean the floor thoroughly and repair any cracks or holes. Then, apply the sealer or coating according to the manufacturer's instructions, making sure to cover the entire surface. This will create a barrier that helps prevent moisture from seeping through the concrete and causing damage.
To effectively refinish a concrete floor for improved appearance and durability, follow these steps: Clean the floor thoroughly to remove dirt and debris. Repair any cracks or damage with a concrete patching compound. Etch the surface with an acid solution to promote adhesion. Apply a concrete sealer or stain to enhance the appearance and protect the surface. Finish with a topcoat of epoxy or polyurethane for added durability.
Some popular interior concrete floor finishes used in modern design include polished concrete, stained concrete, and epoxy coatings.
The best floor covering for a concrete floor is typically a durable and moisture-resistant option like epoxy coating, vinyl flooring, or rubber mats. These materials provide protection and can enhance the appearance of the concrete surface.
