Concrete Patio Resurface - Multiple Layers

[William104]

Hi All,

Homeowner here looking for some expert advice on dealing with a large 1,400sq ft concrete patio that has multiple layers peeling off of it. One layer is a brown concrete paint, a layer on top of that is the horrible Rustoleum Deckover type of concrete cover that is peeling all over the place. I've lived with this mess the previous owner of the home created for a few years now and finally want to get it cleaned up. Ive contacted multiple concrete workers and the feedback on process and costs are all over the place on how to deal with this. What is the best way to get this resurfaced and sealed as new again? Don't want a grinder to make this a slick slippery surface.

Cant attach a photo due to post count?

budget will be a consideration, as the best solution is to break it up and start over with a reputable concrete finisher. Any paint or deckover really must be removed completely - physically and chemically after the physical else anything you put on will eventually or quickly peel or slake off.

Pics will help/

I would agree with the above, if you intend on refinishing this patio in any capacity, you will need to remove all traces of the old which can be cumbersome... sometimes starting from scratch is a better option.

What about grinding down and then adding a thin pour to revive the surface? if done correctly, I would assume it should adhere and possibly be the cheapest option.

Pics would be good.

I'm afraid ripping up and starting all over just isn't in the cards for us. Ideally, grinding down and applying a sealant or new thin pour seems to be the best option? Pictures to follow.

Since demo and replace is not an option, the first thing I would do is grab your angle grinder with a cut off blade and trim off those old anchor bolts where the shed used to be.
Then I’d borrow or rent a serious pressure washer and see if most of that **** could be simply blown away.
Then patch the divots where the bolts used to be and live with that for a while until you figure out the next step. You might end up with a multi color splotchy “camouflage” look. I think anything more than that sounds like more money than you want to spend right now.

What are your planned uses for that huge patio?

If the rest of the concrete is as structurally sound as it appears to look in the upper left of the first photo, then you should be able to grind the layer of paint / Rust-Oleum Deck Restore down to bare concrete.

maybe sand blast

maybe sand blast

It’s hard to sand blast or shot blast large areas without leaving stripes where you inevitably overlap passes. That’s OK if you plan to coat the area but otherwise looks bad.

Not sure why guys are saying demo a patio just to take some paint off.

This concrete looks structurally just fine. The issue is someone put a few layers of some cheap paint down on an exterior surface and over the years it has peeled up.

Mechanically grinding the concrete will not create a slick and slippery surface. It will create an aggressive profile of exposed aggregate.

I understand if you do not want to grind, like someone else mentioned you can try to pressure wash the old coating off. You can then try to scrape the stubborn areas, or use a paint stripper. You can also try a mastic removal head on a grinder and that should not profile the concrete only remove topical coatings. The issue is that this is an exterior slab and topical coating will have a hard time adhering over time with extreme UV and moisture exposure.

I would suggest after "cleaning" all the paint off, you acid etch and use a dye/stain with a clear top coat provided by one of the suppliers on this website that's used to dealing with that.

Thanks for all of the feedback. Structurally the concrete is in great shape with nothing more than some hairline cracks in places. No lifting or breaks throughout almost the entire thing which is surprising.

Seems like the best option is to have it ground then resealed. It sounds like someone I contacted previously is able to do the work and knows what it will take. Looks to be about 2.50/ft for a total clean off grind then clear reseal. I'll look into possibly using a dye before sealing. Should I ask what sort of sealer he uses to be sure it is a quality product?

Thanks again

If you dye the concrete, then you will need a clear topical coating to seal the concrete and make the color of the dye pop. An MMA acrylic sealer would be a good choice for a patio. They are U.V. stable and extremely durable.

Yes, definitely.

He said he will use CSS Emulsion by Elite Crete for the seal.

I just briefly scrolled through the data sheet and this is a 53% solids MMA acrylic[emoji106]. So you should be good

Our suggestion...hire someone to grind it down or rent a good grinder as this disaster must be removed. Then just seal it with Ghostshield 4500/8510 or stain it first and then seal it with Ghostshield. Outdoor projects are challenging due to the UVwhich eliminates or shortens the life of many products.

For an opaque or colored look our Armortop would be a great and well priced choice.
