Silicone sealant?
David Jenkins - 6/10/19 at 02:39 PM

Right... here's a random question for the locostbuilders posse...

I have to replace the seal around the bottom of my shower tray - not a hard job, just a bit of a faff, but I can't work out the best sealant to buy. I've looked at a few products, but some of the negative reviews are a bit grim. I have never had much success with acrylic sealants, so it probably has to be silicone.

So - can anyone recommend a good brand of white silicone sealant? I don't mind paying the price if it really is good stuff, as I don't want to be going back and doing it again in 6 months time.

Should do all you need.

Polyurethane based sealer?
Good excuse to buy (and use) a tube...
Whatever is left on the tube will go off sooner than later, so itīs better to have several jobs ready before opening.

That is so true - I buy this stuff, use what I need, and try my best to seal the tube... and next time I look I have a cylinder of solid sealant.

I might have a go at making some of these on my 3D printer - but I bet they still won't help.

We use this one at work everyday of the week and wouldn't use anything else (NHS Maintenance)

I've previously used a product called CT1, but think they've recently released a new version called BT1 that is similar in terms of mould/fungus resistance. Not there cheapest, but I've never had any issues with it.

CT1, everything else is poop in comparison.

I fit bathrooms for a living and highly recommend the Dow 785 silicone. Most others will go mouldy fairly quickly.
However all silicones will tarnish over time so best to use a good mould and mildew spray regularly in the shower area. This will
extend the life of any silicone you use.
