My husband would like to do our waterline tile. I'm looking for any tips. We have 6" tile picked out and have a rectangular 18 by 30 pool with raised spa. I'm trying to understand the steps. Do we need to apply a waterproofing material before thinset? Thank you for any help.

Laticrete makes very good waterproofing products for applying onto the gunite shell before tiling. The bond beam and unite surface 6"-12" below the tile should be coated with a waterproofing layer prior to the tile setting glue. If you can afford it and have the willingness to use it, epoxy grout will last much longer than standard cement grout for the tile.

Apply the mortar bed, let it dry and waterproof it well below the tile line. Use a thinset rated for submersion and preferably epoxy grout.

What brand epoxy grout do you recommend?

Spectralock Pro Premium grout (Epoxy):
(not sure if you can choose the grout color? - please advise)

Their Permacolor select grout is cement..(but you can choose the color grout)

Laticrete grout products:

Does mortar bed go before the waterproofing on the gunite shell waterline tile or after? Is the mortar bed needed if the gunite shell is uniform consistency where the glass tile is going?

Any special spec on the mortar? Spec Mix is what the contractor has onsite...

Laticrete SpectraLock epoxy grout and it comes in 40 different colors.

You need the mortar bed to create the appropriate thickness for the plaster and waterproofing installed after the bed.

Spec Mix is fine

Would you run the other way if the pool tiler said to use sand/cement grout for glass waterline because it's industry standard?

Standard grout? There's nothing wrong with it and it's lasted decades in many pools but....

If there's something better out there then why not use it?
