DAP High Heat Fire Resistant Mortar is non-combustible silicate cement used for patching chipped firebrick in fireplaces and sealing wood-burning stoves.

It can also be used for applications in wood frame construction where an ASTM E136 non-combustible sealant is required, such as sealing around vents, pipes, ducts and chimneys at ceiling and floor level prior to the application of drywall products.

Questions & Answers

Can this be used to make a seal around a firebox door to a steel smoker.

Asked by: Corey
DAP High Heat Mortar can be used for sealing wood-burning stoves, however, because this product dries to a hard mortar like texture, care should be taken when applying it, to ensure that it does not impede the function of the door's normal operation. Example: an excessively thick application of sealant may not permit the door or its latch to close/seal properly.

Can this product be used to temporarily repair cracks on concrete roof tiles? I know replacing the tiles are the best way to go but we can't afford it right now. Thanks.
Asked by: Copper
This product is only good for repairing mortar where there's no chance of it ever getting wet. This stuff dissolves rapidly when wet. Put it near heat and it gets hard fast and stays that way.

Can this product for me?

my fire place wall was built with steel panel and bricks in 1941. Over the years the mortar between the steel panel and bricks became cracked. Can this Black High Heat Mortar Sealant is an answer to repair the cracked mortars between the bricks and between metal and bricks?
Asked by: Joondae9
DAP High Heat Mortar is designed primarily for small touch up repairs. For larger and more involved repairs, a dry mix refractory cement may be the better choice. Given the age of the fireplace, a proper inspection by a professional may also be in order.
