IFB brick repair

On clayart Steve Mills posted this:

"I usually repair damaged brick with Sodium Silicate 75TW (the liquid variety) and a high proportion of brick dust (same type as the subject for repair), with perhaps a little Kaolin to help the SS bind it together. The balance of the components is crucial or you get (as you know) too much shrinkage".
