1000 Grams (1kg) OO gauge Ballast chippings

OO are 2mm grey chippings. Crushed grey granite that is passed through a 2mm sieve.

Scattered over the exposed adhesive on the Tracklay underlay to quickly ballast your trackwork. Add a small bead of (preferably) rubber based glue to the edges and again scatter ballast to finish the sides off.

our new N/Z  chippings are 0.7mm to 1.2mmmm coloured quartz chippings passed through a 1mm sieve. ( These are a replacement for the old n/z granite which is discontinued at the manufacturer)

It is recomended to rinse and dry before use to remove any dust. ( n.b. the new N/Z chippings are a lot cleaner than the old granite ones)

400g is usually enough to cover 10m of Tracklay Underlay
