On a recent store clean I was asked to go over and have a look at two large paint spills - brand new Tarmac!!
Initial words were No chance!!!
Remembered I had some turps in the trailer and said I would give it a go. The patches were about 3 foot round, lots of splashes and the whole area was a mess. It was where the skips had been and the paint had obviously spilled out of the bottom.
In the past I have seen them use a warming plate to get the Tarmac soft, re rake it and then compact it again. Couldn't do this because it would have changed the colour of the Tarmac.
Dropped a load of Turps on it, brushed it in, with a hard brush, left it to dwell and set about it with a turbo nozzle.
Took a while but it shifted about 90%.
