4100 Moisture-Blocking Clear Epoxy Primer

As a concrete floor coating installer, you know the importance of protecting against moisture vapor emissions (MVE) and moisture vapor transmission (MVT). Few things can damage a concrete floor installation the way that MVE and MVT can. That’s why so many professional installers have started using the 4100 MVE-Blocking Clear Epoxy Floor Primer from Versatile.

This two-part epoxy primer is a low-odor, low-volatility solution that dramatically reduce MVE levels, improving the integrity and durability of any concrete floor.

In addition to priming concrete floors, 4100 Epoxy can also be used beneath the following flooring types to limit the effects of MVE damage:

  • Wood
  • Laminate
  • Vinyl
  • Other moisture-sensitive flooring types

Powerful MVE-Blocking Epoxy Floor Primer

The 4100 Moisture-Blocking Clear Epoxy Primer is a powerful MVE blocker that works well on almost any concrete surface. Our 4100 Epoxy  works by penetrating into concrete to create an MVE blocking barrier. This barrier is so powerful that we’ve seen cases where 15 lbs. of MVE were reduced to a mere 2 lbs., simply by using 4100 Epoxy.

Low-Odor, Low-Volatility, Easy to Install

Professional installers love using our 4100 Epoxy because it is easy to install and adaptable to different environments. The 4100 Moisture-Blocking Clear Epoxy Primer is a low-odor product with no flammable chemicals or vapors. Because of this, you can apply this sealant without disrupting nearby work areas or other parts of your installation process. It’s also adaptive to different environments and work conditions, and can even be applied to wet or damp concrete with no performance issues.

Use as Primer for Concrete

The 4100 Epoxy is an adaptable product with a range of different applications. It can be used as a primer for other epoxy coatings, such as our , our Roll On Rock® Epoxy Flake Flooring System, and our Lava Flow® Metallic Epoxy System.

Whichever way it’s used, the 4100 Epoxy will give your floor the MVE-blocking protection you need as a professional installer. Place your order today and see results on your next installation.

Here is a nice testimonial we received on our 4100 Moisture Blocking Epoxy.


Quick email to send you a pic of a recent install we did in a utility room of a 19K square foot home….stuff works great! Was wondering how this product does on exterior applications that are exposed to the elements. We have a small, 50 sq. breezeway in between two garages that was stained by previous contractors. Because this is a 100% solids product, I am afraid it will amber over time, correct? Please let me know your thoughts as I love this product, but wondering how it will do for an exterior application.”
