Pool Grout - info/recommendation

Hi

In the near future I will be regrouting my pool. Having researched the various types of grout available (porcelain, ceramic, epoxy and silicon based) I'm still very confused which one to use. Has anyone got any info or recommendations on the type of grout to use.

Not the cheapest but does the job. Normal grouts don't last long. I did my pool 10 years ago and it's still OK.

Get all the old grout out first (acid from Mercadonna, black bottle) spray it on and wear ppe.

If you can afford it I would recommend a pool liner.
