Rated 5 out of 5 by from Good bit of kit Does the job, easy to use, would buy again worth the money

Rated 5 out of 5 by from Flue sealant, the best I have used this product on a wood burner flue of which an average temperature of 200•c. After trying other compounds like pastes etc, where these products set hard which make them brittle and easy to break the seal as there inflexible. However when the silicone is applied, like any other type of sealant, it remains flexible. Adhesion is good with no discolouration. The seal has worked perfectly for the first time since installing the burner some years ago.

Rated 5 out of 5 by from Flue sealant I was rather sceptical as to how this could/would work. However, I am very impressed with the product and the ease of use in applying it. In my opinion beats the traditional cement solution. Great product.

Flue Pipe at twin wall joint

Will this seal the flue pipe at the joint to the twin flue pipe collar appox 1.5 m from the top of the wood burner. The space is only a few mm but as the pipe expands when hot , fire cement cracks,
Asked by: tenerifesurfer
Thanks for your question. Geocel Trade Mate Plumba Flue may be used in an application such as this, providing the temperature it is subjected to does not exceed the service temperature of the silicone; which is specified as up to 300 deg C for short term exposure and 250 deg C for long term exposure. However it is worth noting that the movement accommodation factor of this product is ±20% and so a joint with a width of 3 mm would accommodate up to 0.6 mm movement.

does it work on brickwork?

i want to use this to seal the gap between a register plate and my brickwork. So does it work on brickwork?
Asked by: HarveyofLeeds
Thanks for your question. As with all high temperature silicones, Plumba Flue is an acetoxy silicone and as such adhesion to brickwork can be limited. High temperature cements generally have excellent adhesion to brickwork and are resistant to temperatures in excess of 1000°C, however, fire cements are hard and inflexible and could crack if there is sufficient movement (eg thermal expansion). A good quality neutral cure silicone such as Dow Corning 791 has excellent adhesion to brickwork, whilst remaining highly flexible, however, the neutral cure mechanism limits the high temperature resistance and so Dow Corning 791 is only suitable up to a maximum temperature of 150°C. These points should be considered in order to select the best product for your application.

Flue to Register Plate

Hi I was wondering if this is suitable for sealing the gap around the flue where it meets the register plate. Thanks
Asked by: GPD2
Thanks for your question. Plumba Flue can be used to seal the register plates on flues, however, please note that Plumba Flue is resistant to temperatures up to a maximum of 300°C short term and and 250°C long term so you should consider how hot the register plate will get before sealing it.
