大家以为完工了呢，其实，还有一道工序，apply joint sand。我买的是polymeric joint sand，就是为了不长杂草，是我这次改造的重点。去年在前院做了一小块，一年下来，真是没有杂草，效果不错，所以今年大面积还用这sand，牌子也一样，permacon。

Used a broom to remove surplus joint sand and clean the surface


Watering instead of washing. make it like rain. It means too much water if you can see surface run-off.





这回算是完工了。这个周六请人BBQ。谢谢大家捧场~~~
