Tuckpointing pool coping-Question

TRUEPRO

I have a large pool coping project where i have to grind out about 125 joints on round nose brick and i was wondering is there a special additive (latex) r anything that should be added to the colored mortar i will be replacing the current with? Or will the type N be just fine? Wasnt sure because of the pool chemicals that could speed up the process of decay on the current mortar.

Thanks for reading.

You should use a water proof epoxy grout,made for swimming pools,and a sealer made for swimming pools after grouting.

So using a colored TYPE N with Planicrete UA, a latex addictive for mortar repairs, and sealing that wont do the trick?

Heres the link to the product site.

Most of the brick I've fixed on pool coping hasn't failed from the chemicals of the water, but from "sloppy", loose filling of the joints. Most of them that I've worked on were set in the bedding material (usually mortar) and filled with a bag afterward, but were never pushed completely tight. If you consolidate the Type N mud with a filler/tuckpointing trowel, I think you'll be fine. Banding agent certainly won't hurt either. Also, don't forget to treat the control joints in the surrounding slab (only assuming the brick are bearing partially on the slab) as control joints where they intersect the brick..........

Is the pool a fresh water,or salt water??

Well,jomama says he's had no problems,but if the PH get's out of wack it could cause problems with the grout,personally i'd go with the epoxy but it's your call.
