Benefits of Multiple Polyaspartic Coats

[Maximum404]

I have read about floors from various pros and DIY guys that have various coats of polyaspartic on top of a epoxy base w/broadcast to rejection flakes. What are the benefits to 1, 2, or 3 layers of this product? Most of the quotes I have had from pros only do one layer. Thanks!

One coat over flakes will be a dirt trap. Two coats is good and three is really nice.

There are voids between the flakes which eat up the first coat. Leaving it still very textured and prone to filth collection.

Thanks Legacy! After talking to the team I like the most this is what he gave me for details. Thoughts?

final coating thicknesses:
base epoxy, 10 mil, 0.25 mm
polyaspartic, 11 mil, 0.28 mm
urethane, 2 mil, 0.05 mm

Any reason why not using a standard 2 part urethane? Polyaspartics generally cost more and are thinner than urethanes, and are harder to work with. We find that the best finish for a full broadcast is a thick coat of non yellowing clear epoxy and then a coat of urethane.

Full broadcasts are like sponges and really **** up the topcoat. Also make sure to lightly sand a full broadcast first to knock off 'high spot's and vacuum well prior to applying anything, otherwise the surface can be very rough, especially if using flecks that are more than 1/8" thick

Hmm, they use national polymers as a supplier. I'm not sure about the two part epoxy. I do want something chemical resistant and UV resistant which is why I wanted a poly aspartic. They do a pretty large volume and I've seen positive reviews on here, but I'll see what they say about the 2-part urethane.

There is no right or wrong way to do many of these projects. We like to recommend what we know works and what our Install Division installs and sells so we know it works and thousands of clients are happy.

Our top system for long life if doing a full broadcast is to encapsulate with a 100% solids clear and a single coat of urethane protective topcoat or our SPGX topcoat. It's the epoxy top layer that makes it really great since its thicker to encapsulate the sponge-like full broadcast. Many people don't like the roughness and irregularity of full broadcasts if not done using this method. Just our opinion based on experience. Thanks!

Its a good system. He is adding the last coat of urethane as the urethane will lay nicer than the PAP on it's own. PAP dries so fast it can leave a slightly uneven finish.

Should look tremendous when complete, post a pic.

Concur with Scotty, PAP are not easy to work with, they cure so fast. We only recommend 2 part PAP when cure times are super tight such as in commercial applications that need to reopen fast.
