Penntek floor coating experience? Outdoors?

[ndfastang]

Hello all, After 22 years of moving every 3 years for the military, I'm retired and finally having my own 30x48 shop built, starting tomorrow. Looking at the concrete cost to pour and what floor coating to consider, The wife and I realized, we need to address the concrete walk way, drive approach and inside the garage since it will no longer be my shop space. In Wyoming, we have a fair share of snow, dirt and sand that drop off the vehicles as we park. Replacing the concrete is expensive and the gray looks "normal" against our Almond painted house. Looking at Penntek thru a local vendor to coat the 3 car garage floor, the 32x20 approach to the garage and the walkway and front porch that leads to the door in their coating. The color looks great against our house and trim but I worry about the durability of it out in the elements and with vehicle turning on it. It's a Polyurea coating with 1/4 flakes full coated and a Polyaspartic clear over that. They give a 15 year warranty and said it covers everything aside from hammering on it intentionally. They will clean and fill our current weathered concrete top. THis will be cheaper than a full re-pour and we believe it'll look much more appealing.

My question is, has anyone used this or a similar product in the areas I am looking at having coated and how has it lasted?

Thanks all for any insight. I've followed a lot of the posts here and learned a lot about what I'm doing with my shop. Once I figure out a photo hosting site, I'll be able to post pics again and start my own shop build thread. Exciting!

Thanks
Dave

I would surely want references from more than a handful of current customers. Especially on the "15 year warranty". I would be surprised if the color holds up outside beyond a year or two and you are right to be concerned about wear outside as well.

Prep...? Especially "clean and fill" your current pour...seldom does patch and fill hold up.

I would spend an hour on the phone with the folks that do epoxy here, as they have very competitive product that may go up against PennTek and behave better. For longer.

This is what I see quite often:

Thanks for responding!!
I have read that thread. His floor under the coating looks smooth as if it were not cut and prepped right. I'm no pro, but I used what I've read and heard here in lots of posts from the sellers and used here to ask the questions I need. They say it will hold up and not peel with turning wheels on it and will not succumb to hot tire pickup. I'd love the tile in the garage but the slab in front of the garage and the front porch walk need the attention too and I like a uniform look rather than jumping from one material, color style, to another. I'm reading up all over the net and see parking garages (top open floor even), pool pads, walk ways and lots of other exterior pads coated. Even interior of garages and shops but they are all from other installers in all areas of the country so it's a biased opinion. If this stuff works and will last, I'll do the floor in my shop with it as well. Then everything color matches on the property, I've used a local company. I know their other work. They painted one of my newer rental homes exteriors in their cheapest stuff and they did amazing sealing, repair and the paint was awesome. They do good work. This time it's the product I'm wondering about.

I install similar systems for exterior concrete here in the Rocky Mtns of Colorado. The town I live and work in see's about 200 inches of snow per year and these type of systems hold up great outside in my experience.

Instead of flake, I prefer quartz personally, especially for exterior concrete that will see a lot of abuse.

My exterior sidewalk and driveway system is as follows:

Prepare concrete to ICRI-CSP 3-5 surface profile.

1st coat: Apply 85% solids clear Polyurea @ 15-20 mils wet, broadcast quartz to refusal.

2nd coat: Apply 85% solids clear Polyurea @ 15-20 mils wet, broadcast quartz to refusal.

3rd coat: Apply 85% solids clear Polyurea @ 10-15 mils as a grout coat.

**If your installer is not grinding on exterior concrete walk away now.**
