Fitting bath today. -what sealants/hybrids to use??

[bilabonic]

Hi all.

Ripping out knackered bath today. It's up against cheap cladding/leaking from shower, not supported.

I intend to fit new on on 2x1 roofing battens or even 4x2 (I have plenty of both).

All videos I have seen they are not using standard silicone anymore.
It's all BT1 or CT1, OB1 etc.

What do u recommend for first fix seal onto the battens? A suitable clear hybrid??

Then once that has cured what shall I use as final seal that is visible?
I have always used Dow Corning white or have things moved on?

I can see the advantage of using a hybrid on battens as it's will also act as a 'grip'.

Also will be using a smear of LSX on overflow waste.

All iitems need to be Screwfix stock.

Cheers

Yes CT1 then Dow Corning to finish off.

Screwfix do not sell CT1.
They sell this that is an adhesive/sealant.
I presume this will suffice, OB1.

Good reviews etc and comes as as replacement as CT1 when googled.

I think that everyone uses polymer adhesives now just because they are there and available. Me, I think it's a bit of an overkill, I've used silicone sealant for as long as, without any issues, it's a little more flexible and has a bit more give when it comes to acrylic baths so I don't see any need to change.

Silicone adhesives cure to a much harder rubber and are a bit less forgiving, great as a wet grab or semi permanent jointing medium. Though I have seen them pull the top off of plasterboard when flexed to much. Just my personal preference tho.
