Flooring Prep & Product Question

[Cruisinga]

My parents want to replace the 4+ coats of old peeling paint on their 60+ yr old garage floor. The goal is a stain-resistant uniform color garage floor.
The concrete itself is in great shape, 0 cracks. Since I moved out years ago the garage is only used for parking cars and oil changes.

Product Question first-
Epoxy looks great, but stain and sealer seems to be much less expensive. Could a stain and sealer make sense for them? Is old concrete like this a candidate for stain and sealer? See pictures below.

Prep Question-
I am assuming we will need to grind regardless of the product used. I am concerned the several layers of paint will "clog" the diamond brush. Will it?
There have been many oil spills on the floor over the years, is there other prep that may be necessary after grinding?

Thank you for your help!

Perfect candidate for the mastic removal tool (coating removal tool) by Diamabrush.
It will eat through it.

I would still put an epoxy down. Maybe go (2) coats of epoxy/primer with anti-skid in the last coat. Will put you in the ball-park of the sealer/stain but will give you greater protection and better mils thickness (hiding most of the grinding marks).

I used a dimabrush to prep my floor. No coating removal but I am glad the guys at legacy suggested it. Almost rented a local edco but I drove an hour to a home Depot to get a dimabrush. Worth every penny and I was amazed how well it prepped the floor. I used their 55 percent epoxy coating and two coats of that looked good. I top coated with a clear but if you're looking to save a few bucks why not go with one of their cheaper products? Still better than trying to Stai. Or paint again.

Good suggestion James.

Your best bet is if the local rental places have the diamabrush removal tool. If not we lend ours out to customers. You just would need to rent a buffer. If you want a good, affordable system, check out some of the Rust Bullet threads. Two coats of gray after discount is under .80.

If you are looking to epoxy, do it right. Primer. High solids base coat and a good top coat contingent on your part of the country.

I would degrease the floor multiple times prior to diamond grinding followed by a fresh water clean! However once your confident the floor is clean and dry!

I have to agree...start with a diamond brush prep tools/ and proceed from there!

good luck!

Great advice and completely skipped by me. We take a two step approach. Either soak up and degrease or degrease and oil block primer. What do you do there locally?

 

[Cruisinga]

To make sure I understand the prep:
1. Degrease as much as necessary with something like Simple Green or ZEP Purple
2. What do you mean by "soak up"?
3. Grind
4. Rinse with clean water
5. Coat

Justin,
For heavy soiled projects we will let it "soak up" or just degrease multiple times...however we had an issue a several yrs. back of having some reaction between our degreasing agents (sometimes we use peroxide based degreasers and cleaners) and certain primers........once we added a fresh water wash down to remove the degreaser residue the problem went away.

The key is to make sure the concrete is dry after this process!

PRO TIP!--- large air movers can expedite this drying process!

If the floor is lightly or moderately soiled.....ZEP products or simple green should be fine...I would still fresh water wash to remove residue!

Good luck!

Well said Sir. Sounds like we use similar approaches. I swear simple green is the duct tape of cleaning.

Simple green is great! We use SG on our lightly soiled projects but we use it after for all projects to lightly wipe down any light dust and etc.......customer always comment on how great it smells...

Brand new floor and fresh smell.......Happy client!!!

I want to use Epoxy for the floor, but there is a 1' strip of garage floor outside the garage door that sees direct sun. How do I prevent fade/color change/deterioration and still coat this strip of floor the same as the rest of the garage?

This is always an issue that some people need to decide upon when doing their garage. In most cases the coating is terminated at the garage door. Epoxy will amber if you go past that point.

One option is a polyaspartic coating or the newer moisture cured 1-part products such as Rust Bullet or Nohr-S. Talk to Justin from Garage Flooring LLC about the Rust Bullet and Scotty from Legacy Industrial about the polyaspartic or their new Norh-S coatings.

We sell the Rust Bullet and we have Polyaspartic and epoxy products but we do not sell Legacy Industrial products -- which means we do not sell the Nohr-S

Cruisinga: Mr Shea hit the money. Pigmented, aliphatic urethane or Nohr-S will not change color in the sun. Epoxy under a clear-coat of urethane will change color on the exterior and it will be noticeable.

I would choose the system you think will do the best job and end it under the door, cap the end point with a floor seal like tsunami or storm-seal for a nice transition and a good way to keep the weather out (mice too).

In this case, epoxy is just not the best bet for you. There are several urethane product that will work well. Feel free to give me a call or send me a PM so we can go over the best product for your specific application.
