Removal of grout from tarmac

The best way to remove grout from tarmac is to use water with high pressure and a wire brush. I believe this will give the best result.

Best solution is to use a concentration of Grout Stain remover and apply to effected areas as per instructions on the container. Ideally a wire brush or yard broom whichever is indicated for removing the stains. perhaps hose down after with a hosepipe or bucket (s) of water or jet wash ( if to hand but not necessary). Note. Stain remover is available online to purchase.. various brands available.

If the water & wire brush does not work then try grout residue remover, which you can by at any tile shop.

I don't believe tradesmen pay the ridiculous shortlist fees to give advice. They do it for a job. If people want advice they should pay a tradesman for advice.
