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?

Hiya, its just to be a coating and its a new log burner all installed to spec by heats engineer, 10kw Charnwood, its just to stabilise the bricks and mortar dust, I know they wont burn just didn't want something that was going to emit toxins, I don't think they will but double checking to see if anyone has used or knows the answer?

Styrene Butadiene Rubber, which is SBR has quite a high melting point, so should be able to handle 100°C for quite a long times.

If it is mixed in with a render, then thermal creep should not be a problem, if as a coating, then it may soften and move.

 

Why has it been suggested that SBR is added, it is usually as a waterproofing agent.

 

Always best to avoid combustion inside a building, so anyway you can ditch the burner.
