Answer
Epoxy with two-part polyurethane varnish
Two to three coatings of epoxy also give a strong basis for transparent two-part polyurethane finishes. Applied over epoxy, they function excellently together and outlive any finish employed by itself.
Then, can you add water based polyurethane over epoxy resin?
Though the epoxy levels of its own accord, the surface isn’t exactly even. I sanded the epoxy surface with 400-grit wet/dry, and then applied a water-based polyurethane. However, I can see scratch marks on the epoxy from the wet/dry paper through the polyurethane finish.
Subsequently, issue is, can you add polyurethane over glazing coat?
You may transform any clear finish into a glaze by adding colour, or you can purchase a pre-mixed glaze. Oil-based polyurethane and epoxy resin glazes work best on cured polyurethane. Apply with caution.
People also question, can you clear coat over epoxy?
Technically, you could rough up the finish of dried floor paint and use a water based epoxy as a clear layer. Most other clear coatings are not acceptable owing to their solvent basis. They may actually soften these paints upon application and cause them to pull up from the concrete.
Will epoxy resin attach to varnish?
As a general rule, epoxy should not be put over other coatings. An exception is water-based stain (if it has been let to cure sufficiently) but anything containing solvents can cause harm to the epoxy layer, or the epoxy might weaken the varnish/stain.

Can you pour epoxy over cured epoxy?
Can I apply another layer of epoxy over cured epoxy? Yes. Since the epoxy has dried a chemical bond is not feasible , what is termed a mechanical bond is required. This simply means that the cured epoxy needs to be softly sanded before the second coat is applied: the first layer should have a matt, nearly white, surface.
Does epoxy require a top coat?
The major benefit of epoxy for a clear top coat is affordability. Epoxy is the least priced choice in most circumstances and as long as it’s not solvent based, it will be low in VOC’s as well. Epoxy may also offer for a thicker single coating of up to 10 mils depending on the solids composition.
Can I apply shellac over epoxy?
While you can apply shellac over epoxy the epoxy itself should be significantly tougher, plus it’s waterproof and not sensitive to alcohol. “There is likely more mystery in finishing than in any of the woodworking techniques, and with (maybe) less solid cause.”
Can I put polyurethane on countertops?
Polyurethane varnish is one of the greatest finishes for a countertop — it’s durable and, when done correctly, can be just as subtle as lacquer. Best of all, applying polyurethane doesn’t need spray equipment and is a task you can easily perform yourself. Oil finishes tend to sink into the grain and yellow.
What paint will attach to epoxy?
Generally, epoxy primers and LPU paints are compatible with epoxy resin coatings and may even chemically bind. However, some of the alkyd enamels and other one part paints and varnishes may not properly cure over epoxy resin coats.
Can I spray lacquer over epoxy resin?
1 Answer. Lacquer can stick to epoxy. At worst apparently the scratches remain clearly visible in the epoxy surface underneath the topcoat, they don’t get ‘wetted’ by the topcoat as they would if you were applying over a layer of the same finish.
What is an epoxy finish?
Epoxy coating uses a chemical mix of two liquid components, epoxy resin and hardener, to create a tough, solvent-resistant finish that can be applied to floors, countertops and decks. Many types of epoxy are noted for their durability and can be used to seal concrete floors, steel and other industrial materials.
Can polyurethane be used as resin?
Polyurethane resin is used in an extremely wide range of production products, such as rubbers to medicines. There are many advantages to polyurethane resins. These materials are commonly praised for their chemical, oil, and grease resistance, as well as their abrasion resistance, and as a result, they are not easily torn.
Is it possible to paint urethane over epoxy?

The last time Len posted was on March 18, 2006 at 10:59 PM. bs35j, The answer to your question is “yes,” urethane paint can be sprayed directly over epoxy primer without any problems.
What exactly is two-part polyurethane?
Polyurethane is perhaps best known as a varnish-like finish that can be purchased at paint stores and home improvement centres. The two-part polyurethane finish (used on wood and metal) is made up of two components that are mixed just before application to create a smooth finish on the surface.
Is it possible to apply polyurethane to laminate countertops?
Layers of polyurethane should be applied. Seal the kitchen countertops with three coats of polyurethane to ensure that they are completely waterproof. A satin or glossy polyurethane finish will give the kitchen laminate countertops a high-end appearance and feel. Allow each layer to dry completely between coats before applying the next.
