Right, having scraped about 4 buckets full of weeds out of the patio and pressure washed it such it's no longer black and green, but a rather shocking yellow, it's time to regrout it.
Can any of you recommend any brand of ready-mix dry patio grout? Since the slabs are textured (and rather wonky, which I'm not going to fix - this is a bodge!) I don't want to use a wet system such as shown on Pavingexpert's site (I don't want to hire a cement mixer, either!)
