How long does concrete need to cure before coating?

A normal concrete mix must cure for at least 28 days before coating. 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. Radiant floor heat is NOT an issue for coatings.

What happens if you don’t etch concrete before epoxy?

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 are the disadvantages of epoxy flooring?

  • Temporary flooring solution.

  • Tedious installation process.
  • Complex Removal Procedure.
  • Costly Maintenance.

Can you put resin over 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.

How can you tell if concrete is cured?

The most direct way to measure curing effectiveness is to evaluate a surface property that is influenced directly by curing, such as abrasion resistance (ASTM C 779), surface hardness (rebound hammer ASTM C 803), rate of absorption (ASTM C 1585), or deicer salt scaling (ASTM C 672).

How long should concrete cure before putting weight on it?

Your concrete should be solid enough to walk on, without leaving footprints, after anything from 24 to 48 hours. By seven days, your concrete should be cured to at least 70 percent of its full strength..
