Rated 5 out of 5 by Fernox Leak Sealer This product performs excellently for jointing BSP fittings as well as sealing 'old' weaping joints. A must have for all tool boxes! It is silicone based but the fittings are watertight immediately so you do not need to allow time for the paste to cure. NOT FOR USE ON GAS FITTINGS. 12 Oct 2011

My shower trap is leaking between the rubber under seal to the bottom of the tray. If I loosen the trap and put some of this in where the rubber seal is, is this stuff suitable?

Does this act like an adhesive and make it difficult to remove in the future or can it be removed easily?

Answer: 
Yes LS-X is suitable for this use, it will act like an adhesive but can be peeled/scraped off if you need to remove it.

The leak is definitely coming from the plug/trap area but I didn't want to start putting loads of sealant on if you're not supposed to. Also, if the paste is suitable, do you use the same amount as silicon? It's a ground floor shower with a slimline trap.

Answer: 
Hello Denise. If you are just sealing a leak in the washer, LS-X would work fine as it is a high quality leak sealer. A small amount should be sufficient, but please refer to the instructions when applying to get the best results.

Hope this helps.

Answer: 
Hello Lyngst, you can use LS-X leak sealer, however the radiator needs to be drained and dry in order for LS-X to key to radiator. You may find it easier to use our F4 Leak Sealer 500ml or Express, as this can be added to the system via the radiator or header tank and will stop pinhole leaks.

I have a weeping joint where the central heating pipe connects to the radiator. I don't really want to drain the pipework down to dismantle the joint. Will this product work by wiping it over the leak?

Answer: 
Hello Ocheok. Unfortunately this will not work, as LS-X needs to key to a dry surface for half an hour before curing. Instead, try either our Leak Sealer F4 500ml or Express, as this is designed to stop weeps and pinhole leaks without needing to dismantle or drain down the system.
