  • we have a block-paved drive. after 5 years it is looking a bit mouldy/tired, with a few weeds at the edges. i was thinking about pressure washing and sealing it - but youtube says pressure washing can reduce the life of the driveway....

    thoughts? experiences? concerns? tyia

  • thoughts?

    Pressure wash.

    Of course it will reduce the it's life, but the question is how much? Are you going to become that guy who's pressure washing it every Saturday? You've gone 5yrs without gaf, so my money is on once every 5yrs being fine. There is probably a mild detergent that will help. Also once dry brush in kiln(sp?) dried sand. But make sure it's really dry and use a soft brush - it's easy work, but as soon as there is moisture it takes x10 as long.

    We decided not to seal when we had ours done due to the small area of high traffic. I'd rather have the whole thing look a bit faded than have two neat bare tyre wear lines down it.

  • Whatever you do will reduce the life. Hypochlorite is an easy option - put it on, leave it and rain will do the work.
    Pressure wash can be quicker with a big enough washer.

  • Pressure wash it. Who wants to live forever? It'll probably still be fine when tearful relatives are saying what a nice person you were.

  • I pressure wash mine then weed and rake out the blocks and brush in som kiln dried sand. Jobs a goodun

  • My neighbour next door to my parents has pressure washed his about once for 15 years and it’s still there. I’d do it and not worry about it if it annoys you that much although I feel like it never lasts that long
