Remove cement/mortar from tarred driveway ?
Hi,
I recently had a boundary wall replaced, and the builders were a bit messy with the mortar, and the short driveway is looking very messy. I was intending to get it off while it was fresh with a power jet, but a couple of days of hard frost later and the morter is well hard. I know from experiece that using a high-presurre with a "pulsing"? nozzle is great at cleaning /removing but this is too vicious and breaks up the surface of the tarred driveway. I will eventually be replacing it but is there a quick/easy way to remove the mortar off without affecting the softish tarred surface ? I recall reading that dilute Hydorcloric acid eats cement - but what would it do to tar ? ... and can this simply be washed down and diluted flowing into the street/drains. -- Ham |

I wonder if it would be easier to apply a second coat of tar-paint of
somekind and camouflage the cement droplets into the tarmac background? |

If theres any residue, HCl aka brick acid removes the remaining stain. The important thing is not to leave them, as over several days they will harden in a big way. Freshly dry mortar is weak, but not for long. Tarmac is very slighty flexible, cement isnt, so if you get no other ideas I'd try tapping them with a hammer, they may break off or break up. NT |
