Hairline Cracks on Concrete Deck

[lilhall]

HI All,

I have numerous hairline cracks on my concrete pool deck. The deck paint does not fill them in so I am looking for a product I can use. They are too small for caulking does anyone know a product I could use to fill them in before I re-paint.

Thank you in advance

Epoxy concrete crack filler.

Show us some pics of the cracks.

This is not my area of expertise but I don't think you will be able to fill them as is. You have to either cut them with a saw or chisel them out to make them wider. Then add a crack filler. If they are small and not growing, you might be best to just leave as they are.

my concrete guy used an angle grinder to make them V shaped, then filled with epoxy

I used https://www.lowes.com/pd/QUIKRETE-Concrete-Crack-Seal/3006115 and just let it sit on top of the crack. I figure it is going to keep the water out and that is the point. I am not too fussed about it looking perfect. I poured it on then used a small brush to smooth it out a bit or else it makes a kind of hump.

I think it you want it to look nice though you will have to make it a bit wider so you can put in something that will fill in, instead of sit on top

I've used that before with disappointing results. But granted, I did zero prep. Had I cleaned the jagged edges of the crack a little, it might have worked better.

Yes, it is not a good long term repair, but it is easy and cheap. It also isnt too strong so if your concrete shifts again it will crack, but it does keep the water out and keep the elements from wearing away the edges.
Also, Mine has only been on for about 4 months, we will see what the winter does to it. If shirker has used it and it didn't hold up , I will probably have to end up using something else myself.

I just found this video

Look at the 1:42 mark. looks like they definitely used some tool to widen the crack a bit so the material can get in there.

The cracks are all small but seem to get worse every year. see attached picture shows the cracks in the white area

is that cracking in the concrete, or just the cooldeck?

'Into the concrete and there is a lot of them. I plan on patching and then repainting.
