Heat Resistant SBR/Brick and Dust Sealer

[Strangey71]

Hi everyone

We are placing a log burner in a big hearth that is brick and mortar now as I removed all plaster and cleaned for ascetic purposes, could someone recommend a heat resistant  SBR or Brick and dust sealer thats Heat resistant or suitable for this. Is ordinary SBR any good for this?

A new burner should not emit too much heat to the sides, or through an insulated flue.

If it's an old burner then it won't meet regulations  so I will be careful not to encourage misuse.

Eg insulated flue, chimney liner, air intake.

 

I didn't know what SBR was but looked it up. Does the brickwork need coating or protecting? Is the SBR to be a coating or a mortar additive?
