Garage floor painting

[PFlorenzano]

Hello,

This is my first post and hoping I can both gain and share some knowledge here.

I have a generally new construction home with a three car garage that I'd like to paint the concrete floor. I accidentally dropped some oil on the concrete and have some rust stains from an ATV plow.

From what I've been reading, shot blasting is the way to go to prep the floor before painting it. With that being said, will shot blasting remove oil, fuel and rust stains from the concrete?

Also, I was thinking about using Sherwin-Williams Armor Seal 1000 HS Epoxy Does this product work and hold up good?

Thanks again.

What you want to do is apply a floor coating, not paint. Shot blasting is going to be too aggressive for the type of epoxy you want to apply. That type of concrete prep is generally used for commercial operations requiring multiple coat high solids systems. Grinding the surface for your garage would be the best prep. The Armor Seal is a thinner mil epoxy that would not fill all the voids left from shot blasting.

Subscribing, I am thinking about using this same product in my shop.

with the vendors and sure fire products available here, I don't understand why people want to buy products that are risky and prone to failure, barely enough product supplied and finished goods that are documented to have problems.

We have available at a few minutes notice, some of the best flooring products and support, some even after hours and holidays, should we have questions.

There are plenty of pictures and descriptions of large, beautiful, and small and successful - DIY installations here to see.

Why take the chance???

THAT is a great question!!!
Thank you for asking.....

I did Rust Bullet and am very happy with it.

Hi
We carry an Oil Stop Primer that will adhere to floors with residual petroleum products in them. We would suggest a good cleaning/scrubbing/degreasing and light sanding, etch, then prime with the Oil Stop Primer. The entire floor should be primed with this, as if you don't then the primed areas will look different when epoxy coated then the rest of the floor. Cost runs in the $1.00/sq ft range with discount for 3 layer 100% solids system with flecks and topcoat.

When you mention 'grinding the surface' vs shot blasting, do you mean diamond grinding?

Hi,
Here is a helpful link from our commercial Prep-Crete Division's website to see the differences in surface prep. Feel free to contact us directly with any particular prep questions, especially on mechanical prep methods, types of diamond tooling, etc.

Yes. It's a much better surface prep for the typical floor coating materials used on a garage floor.

Shot blasting will leave "corn rows" that require a very thick coating or slurry to fill in the rows and smooth things out. Check out the link that ArmorPoxy left. One of the pictures shows a concrete surface with the rows. That is from shot blasting.

Thank you for the information,

Would you be able to send me a color chart? I'll send you a private message with my address.

Thank you Shea, it's much appreciated.

Second question, will Diamond Blasting remove light rust and oil stains from the concrete surface, or do I need to purchase a solvent or other product for this?

 

[Armorpoxy]

Shea is 100% correct. Shot blasting leaves rows or 'lawnmower lines' as we call them so if a thin mil coating system without aggregate is being applied the floor usually needs to be grinded after shot blasting prior to coating.

We always disclose this to our clients before we start. Shot blasting though is VERY effective at removing old **** from the floor since it is a 'top down' method and gets into the low spots. Grinding being a horizontal prep method cant get into low spots.

So..each job is different and we recommend what is needed for each job taking into account desired end results, budget, surface conditions, etc.

 

[Armorpoxy]

To clarify, there is 'shot blasting' and 'diamond grinding'. For most applications in garages diamond grinding will work fine and will remove light surface issues including oil stains and such. If the floor is pockmarked and beat up, then grinding wont work well.

Shot blasting for small areas is usually not suitable since the machines are large, don't get close to the edges, and the commercial machines require 3 phase power.

It sounds like diamond grinding is the way to go. The house is only 18 months young so I'm going to look into renting a diamond grinder to prep my garage. Thank you again for your prompt response.

So which kit do you recommend for a 450 sq ft space? I'm looking to purchase a kit within a week or so.

Thank you

We recommend the Armorclad Master Kit with primer and upgraded topcoat. Thank you.

Hi,

Does the Armorclad Master Kit come with an etcher? If so, is it necessary to diamond grind the floor of a fairly new house with no previous coatings with light oil stains on the concrete?

Sorry for all the questions, just want to be sure I'm getting the right kit.

Also, would you be able to send me a sample of both the (dark gray with whisper gray flake) and (medium gray with maui blue flake)

Thank you,
Pete

 

[Armorpoxy]

Hi,
The kits come with etch which is normally sufficient for most surfaces. Grinding is always best, but we have tens of thousands of installs done with etch with no issues. We do though recommend using the optional primer which is available in an 'Oil Stop' version for surfaces with residual oil. Please call to order as that combo is not sold online.

Our records show that fleck samples were sent previously via regular mail. If they did not arrive, please contact us directly, not via GJ to reorder.

Unfortunately the only sample chips we have made up are our standard seven color combos, we don't make up custom base/fleck samples.

Thank you very much.

 

[PFlorenzano]

Excellent, thank you for the advice. I'll be sure to call sometime this week once I decide on color.

What's the best floor, and wall, coating that will reduce moisture? This is for a garage built into a hill do one full wall and half of two walls is under ground and there seems to be a high moisture level. I plan on parking my classic car there and installing a dehumidifier.

Looking at you pool coating, does that adhere to only plaster? Will it work on steel?

 

[mcbassin]

PFlorenzano,
What did you decide on for a floor coating? Did anyone ever reply about the Sherwin Williams product? I'm still considering it for my garage.
