Product Information

After curing any fine cracks that may appear in the cement should be filled with the same material to ensure an air tight seal. And if worst comes to worst and you think you need to claim (v rare) then your invoice should probably suffice with them, but as you are trying to do it is best to cross the T's etc. If no gap to non-combustibles recommended then we suggest 50-100mm air gap left and right of stove, 50mm behind and 100mm above. As time passes, you will note that the cement seal at the base of your flue pipe, where it blends into the outlet collar of the stove flue, has broken or crumbled, probably because of the slight shift in the stove balance when you open and close the door over many months.

Let's take a look at how fire cement may be used to your advantage, its drawbacks, and how to use it for long-lasting relief from any cracks.No wood-burning stove installation is complete with a trusty tube of high temperature silicone sealant.

Flomasta Fire Cement 2kg - Screwfix

Forget CO poisoning my friend - unless you get your several tonnes of (dry) wood sourced and stacked (under cover), and learn to use your stove in good clean-burn mode (can't tell the make from pics, but it looks like Dovre styling), then it's sounding to me like you are in more danger of having a chimney fire within a few months, destroying the integrity of your expensive new liner in the process. As you tip the insulation into the stack, tap and shake the flexible flue liner a little to make sure the vermiculite travels all the way to the bottom of the stack. It depends on a brand to brand, but the generally accepted curing time is 12 hours from the initial application around the cracks.

The kW output is completely dependant on the amount of logs burning at any one time - more logs burning equals more heat. Especially since it does not come in contact with the stove, but only gets heat from the pipe, any amount of heat from medium to high setting should do the job in around four to six hours. Most products will list specific appliances that they can be used for, such as furnaces, boilers, stoves, chimneys, and combustion chambers. Pull the hook back after you're done, otherwise the cement will continue to come out of the gun's nozzle.
