Sunday. Got friends to lunch here today, so I'll be off a bit early. If it's warm enough we might be able to dine outside, but I doubt it! A few bits of last minute shoplifting to do.
Have a happy day everyone.
Ok Smow brush it all away, get you down to builders supply or your local shed, mix will be 1 part cement, 3 parts building sand and 2 of sharp sand. Mix it together, not necessarily at all time, and just brush it into joints. Just keep your cement dry.
Moisture from ground will make it set, you might want to finish joints with a piece of 15mm copper pipe, if not then you could use a piece of normal hose pipe.
