Can you remove cement?

[Alex evans]

Hey guys. So ive a concrete patio and i had a few big nasty cracks in it.

So i thought, for saftey and look id fill them with cement

So i did.

However

Ive now got a few sploges, some bigger then others of cement on the concrete

Anyway i could get rid. Been about 3 days so obvs its set.

I wash thinking jet wash?
Electric sander?
Maybe chishel or scrapper.

Any idears?

Thanks all!!!

It depends! On how thick, messy it is. Disclean will dissolve cement. Or try mechanically removing it with a cold chisel or carborundum stone.

Probbaly biggest 2mill MAYBE SOME 3mill

Just knock the lumps off with a spade, scrape it clean with a wallpaper scraper and then pre wet the surface and pour a little bit of mortar acid on them (brick acid) dilute it a little and give it a scrub and wash off after 10 mins. Repeat if needed.

This may cause slight lightening of the concrete in the immediate vicinity but unlikely if its very old. Try a test patch first if your concerned about that.
