Foundry DM Red Sand

Foundry DM Red Sand

Supplied in 22 Kg approx Bags
Foundry DM Red sand in its raw mined state it will require Bentonite clay powder adding at 5 – 10%.

Due to being in a raw unblended state the Moisture content may need adjusting once clay has been added proir to use.

The sand must not be too wet or it becomes sticky, nor should it be too dry as it will not form correctly and crumble. Remember to do the hand squeeze test, it should easily mould to shape and not stick to your hand but cleanly break when snapped without crumbling.

If working with cast iron you can add 3 to 5% of coal dust which will help gases escape and produces a smoother casting.
