Readers ask: Does epoxy resin stick to concrete?
Concrete epoxy adhesives: A quick briefing When equal volumes of the resin and hardener are mixed, they react to produce a tough, rigid, high-strength bond. You can use epoxy resin for concrete to repair, fill, bond, and rebuild concrete surfaces.
Do I need to seal concrete before epoxy?
New slabs of concrete should be allowed to fully cure for 30-60 days before a coating is applied. If a sealer was previously used on the concrete (if water beads up on the surface), do not use epoxy. Any cracks or concrete spall should be filled and stabilized before a new epoxy coating is applied.
What will epoxy resin not stick to?
Epoxy resin adhesives will bond all woods, aluminum and glass well. It does not bond to Teflon, polyethylene, polypropylene, nylon, or Mylar. It bonds poorly to polyvinyl chloride, acrylic and polycarbonate plastics. The only way to tell if an epoxy will bond to a material is to try it.
Can you apply resin to concrete?
Resin bound surfacing does bond well to concrete surfaces. Concrete is capable of absorbing moisture but it is not permeable. And therefore care should be taken to install sufficient ‘falls’ and drainage when installing a concrete base, or laying over an existing concrete.

Epoxy corrects a lot of damages that occur to concrete structures. It’s a relatively fast solution to fixing concrete driveways by putting a epoxy film over the tiles that form a protective coating. On the surface, the moisture is prevented from sinking into the concrete.
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.
Can you epoxy over wet concrete?
Moisture beneath the slab will permeate to the surface of the concrete. Because coatings such as epoxy are impermeable and do not breathe, water vapor and moisture can’t pass through the coating.
Do I need mold release for resin?
Mold release is necessary when working with resin. There are many types of resins for projects, but they all require a mold release to keep the resin from sticking to the mold. Failure to use a mold release generally results in a ruined project, mold or both.

Does resin break easily?
It is water-resistant, not prone to cracking, peeling, or other damage, and it is a highly durable material that will not break easily or shrink once hardened.
