We have this job to quote, i have taken a picture to show some potential issues.
Usually when those white bits are blasted off, underneath its usually black and stained.
Can anything be added to remove the black stains, like chemicals?
Pre treat them?
We use a petrol driven pressure washer, but i dont think its the calibre of what some of you guys use. We have got this turbo dirt blaster nozzle and that eats dirt.
I dont really want todo pressure washing, so have passed it on to my dad. Had 3 calls come through this week for quotes hahaha
