Damaged brushed concrete surface - repair ideas? - Careless whiteliners!

[Dave_L]

I've been asked to quote to restore the concrete surfacing to the brushed finish before the white lining was applied in the wrong area as seen here in the pics.......

Is slab replacement the only viable option (as this is a new industrial development) or could it be planed off and a new section laid in, rather like a tarmac overlay?

[lutonlagerlout]

has the hot paint affected the surface dave?
is there no way of removing the paint or has someone tried that?

[Dave_L]

No, they've scabbled the (incorrectly placed) white lining off the new brushed concrete and the tips of the scabbler have removed the brushed finish - the owner isn't happy with the resulting finish.........

If it had been me I think would have tried some acid-wash or something to lift the paint and not something 'mechanical'

Guess the options are use a thin resinous overlay and try to brush sure Simeon from ronacrete has something.

Cut the strips out and relay but still going to have a joint line or mill them to say 40mm use a strong mix and try rebrush

Cut strips out and lay accos

You can get special concrete cutting machines they use them on run ways etc it's a series of blades mounted next to each other in widths from like 400mm to 4000mm truck mounted ones and they grove it but bigger groves then brushing

Can't find the link but there was a bit in erthmovers about them a while back

[Dave_L]

Hmmmmm all good ideas - personally I think the bloke is being a bit of an asshat demanding it to be restored to a brushed finish.

I was thinking along the lines of dropping our cold planer into it and milling off 40mm or so and relaying it........not really sure if it is practicable or not.......

Personally i'd just live with it, it's only an industrial area by the looks of it. seen a lot worse

But I guess White liners insurance are going to be paying, I'd just live with it it'll weather in in a year or two

That's exactly what I'd advise - if any repair is carried out there will be another joint - potentially another weakness.

I think there is more to this than we are seeing, to be honest.

I would be pished off with the scabbling
why they couldnt use summat else is beyond me on such a nice brushed finish
as you say dave , i reckon someone doesnt want to pay

We repaired some new brushed concrete last year after some one set fire to a car on it we cut loads of strips in it with a stihl saw about 15mm deep I think and used a breaker to chip it out and used paveroc made by fosroc to overlay it, there was a base component to put on the bottom and then add specified amount of water to premixed bag and finish just like normal concrete, it wasn't cheap though.fosroc

Only way Ive ever seen it been removed is with a burner. That job looks brand new, suppose he got the plans upside down :laugh:

Many thanks...I will investigate that route but there's a fair bit of cutting/gunning to be done there! Bloody hard work if you ask me!

But what is the other option? Lift the whole slab and start again??

[pickwell paving]

Either that or the fosroc/paveroc route or as Giles suggested I think ronacrete do something similar, your idea with the planer would be easier than stihl saw or floor saw, just had a look on the website and paveroc can be applied from 12mm - 100mm in one go or built up in layers.

[simeonronacrete]

We certainly do have repair mortars for that. A rapid strength gain mortar suitable for minimum 6mm application depth will do the trick.

If you prefer we can produce a light grey grade to make it less visible - although it'll probably always be visible and the client must decide what is the best; repair or leave as is.

Our Ronacrete RonaFloor Repair 1 Hour 6-50mm repair mortar will be strong enough after 1 hour to traffic - foot and car.

Min/Max: 6mm/50mm per layer.
