Edge Tiles on Acrylic Pool not sticking Hi Guys,
Just wondering if I could get some advice.
Over the last 10 years we have had several unsuccessful attempts at securing some bull nose edge tiles to the top lip of an in ground acrylic pool. The original builder had two attempts over 7 years, and then 3 years ago we sourced a "specialist" who tried again (at some considerable expense). As of today, about 70% of the tiles have lost adhesion to the acrylic pool lip which they sit on.
The decking around the pool is timber, so the tiles sit alone on the lip of the pool. Being bull-nose style tiles, I suspect that when people stand on the edge of them, there is a massive force levering on the tile which eventually breaks the adhesion to the acrylic pool lip. From what I can see, the "glue" is one of those flexible cements - white in colour. I can't remember the name, I just remember seeing it being mixed.
Having spoken to a few other people, I'm coming to the following conclusion:
(a) I should be using a adhesive like Sikaflex 291 or similar, not a cement based product.
(b) I should use something to score/scratch the surface of the acrylic pool to help the adhesive key into it.
I'm going to give Sika a call to get some advice, but your comments would be appreciated as I feel we should be getting more than 3 years out of the adhesive.
Cheers,
Luke
Update:
After speaking to the SIKA technical specialist, he believes our problems have been due to the previous adhesives being attacked by the Chlorine from the pool water.
His advice was to use Chlorine tolerant adhesive like the Sikadur-33 epoxy.

Almost any epoxy glue should do the trick, hower it will have to be keyed into the lip of the pool.
A 40 grit disc on an angle grinder will short of this.
Good luck.
PS. A tile glue called Optima can be used underwater, but it's not cheap.
Growing old is compulsory, growing up is not.

I have just read your advice on what to use to correctly glue bullnose tiles around a pool and I'd like to say thankyou very much.
My husband and I are just putting a pool in and we were discussing this very topic today and we both agreed that we needed to find out how to do the job correctly.
Our pool is completely indoors and so we need to direct the water runoff towards the pool unlike an outdoor pool where the runoff is directed away from the pool.
I could just about write a book on all the regulations that we need to follow like concrete piers1500mm apart with a concrete bond beam on these piers, heaps and heaps of concrete!!!!
Anyway thanks again,
Baretta
I thought I would provide an update.
After lots and lots of advice, some that was incorrect, we settled on a product (and advice) from Tilers Express in South Melbourne. Mapei Keralastic. It is a two-part polyurethane product.
These guys were really helpful so I suggest you call them and discuss your specific application.
Luke
