Reply to Rsposta4u's Post: I am filling in a pond, I have filled the bulk of the pit with plain ballast stone, now I require to end up with an attractive finish,. I have purchased a large quantity of Highland pebbles because they were shown on display as bright and shiny. The supplier claims the stones he showed me were wet when seen,despite 1 weeks hot dry weather when i ordered them. They were delivered bagged and dull. Somehow I need to "dress" the pebbles to form approx 25mm surface on top of the ballast. best treatment so far 2 times coat in 5water:1pvA allowed to dry then 3 water :1pvA for dull shine.
