Lanko 751 or Weber dry Tex for wall render

[AJBangkok]

I need to render the walls and floor of my pool to complete the build. My builder is suggesting using Lanko. 751 additive to the render and a pool company is suggesting using Weber dry Tex that comes in a 20kg bag.

Which is better or is it neither here or there.

from what i read weber is better, thou still i think it doesnt matter too much

They are not the same.
Lanko 751 is used as bonding additive between old and new concrete.
Weber dry.tex is a waterproofer. And it works- at least for what i have seen, but i don't know long term. I used it almost everywhere.
My lanko 751 experience is not too good. After use i found everywhere plastic-like wires, but I guess that is just what it is supposed to do. Not used it a lot. Used weber.latex on other occasions.
Now I would just use weber.add (or crocodile or whatever brand) of waterproofer (naam gansuum) with the render. Cheap and sufficient.

If the walls were constructed of water proof concrete, and the render has waterproofing additive, and if special tile adhesive and grout for pools is used, it's not strictly necessary to add another skim of expensive waterproofing slurry.

Indeed, there's no big difference. I'd choose weber though and my friend uses it too to render the floor and walls.

simila to my thoughts... if you have waterproof concrete already ... i was wondering (cause i liked to have rounded corners) i just put one more water proof plaster in the color of my choice to make everything smooth and then put this TOA

or any other brand ..

anybody tried it like that
