Foundry DM Red Sand

Description

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.

We stock Bentonite clay and coal dust in 2.5kg, 5kg, 25kg or 1000kg

Please note bag weights from the supplier vary from 20 to 25kg but are never under 20kg

(Please note we can only ship 1000kg bulk to UK Mainland only)
