Polyurea on a new slab

[PNWguy]

I'm considering polyurea on a new floor for my woodshop, garage and shop (3 different spaces).

Woodshop - 480 ft
Garage - 720 ft
Shop - 1,280 fy

I'm looking at SPGX, the kit from GarageFlooring and whatever else is recommended here.

My two biggest concerns are about gloss and welding.
1) Can the finish be dulled in any way? Every photo I've seen makes the floor look reflective - with big reflections from overhead lighting. I'll have 10' and 12' ceiling with T8 LED tubes.
How is it in real life?

2) What's up with welding? Am I going to destroy the floor with welding? I weld on occasion, not all the time.

You can put an additive like our HDGrip-SoftSkid into the clearcoat, “ultra-fine”. Adding a little more than recommend really knocks it down. Remember, gloss means strength and all gloss will soften over time.

These floors are polymer, so they melt under the heat of welding debris, cover up or go outside.

Good luck.

What does welding do to the floor? Does it melt and leave black marks? Can the damaged areas peel, or do they just look bad?

Does it melt at a low enough temp that using a grinder by the floor will mess it up?

 

[LegacyIndustrial]

Grinding can actually create a hotter ember than a welder under the right conditions.
You can get small marks which over time can look less than great.

We have a more weld-friendly called HellFire Concrete Coating if this is an important consideration for your shop.

Hellfire looks interesting.
For new construction, how long of a cure time would you recommend, and what finish on the concrete?

Caution and care should be used when welding over any coating. Molten metal is well beyond what any coating can tolerate. Even coatings like Rust Bullet will fail at full temp. Usually an easy fix. Use a welding blanket.

The more anti-skid you use the more the finish is dulled. There are limits so work with the supplier on how much to add.

30 days, smooth (not burned) finish.
Prep per the instructions.

Do you have a recommendation for a product you carry?

I have problems with my polyurea discoloring around the machine tools and benches. Anywhere with a lot of oils. It's a working area and isn't offensive. But I would recommend putting down plenty of mats if possible. The gloss has definitely faded after about 1.5 years of heavy use. I definitely use mine well above the standard expectations for a garage floor coating and it has held up well.

Our Polyurea kits are a great value and calculated at a higher mil thickness. https://www.garageflooringllc.com/polyurea-garage-floor-coating-kits/

I just finished polyurea (from Legacy) in my 28x40. It hasn't dulled yet, but it is only a month or two old. I have slid quite a bit of stuff on it, and it seems pretty durable.

But, as always, YMMV.

Nice looking floor. Did you apply it yourself, or hire it out?

Is it that reflective in person? It looks like overhead lighting would be difficult in there.

The biggest oil problems I have would be next to the mill & lathe. I do try and keep the floor clean, because it's slippery. Also, at least one of the damn chainsaws always seem to seep bar oil; I should just build a sandbox under them.

In front of the mill and lathe is where my floor is discoloring, looks stained from oils. From a durability standpoint I'm fairly pleased with the product. But I would probably have been more proactive in terms of mats in high traffic areas. The chips will dull the surface if you walk on them (should be expected).

I've not personally seen an issue on the bar oil and polyurea products. Would love to take a closer look at what is being used in this area and the run some tests. PM me as there are a couple of options

SPGX is gloss only, but can be made lessglossy by adding more non skid additive.

As for welding, welding sparks don’t bother it but no coating omg snow burn marks from slag so protect the floor with metal sheets or welding mats as required.
