 Caulking Acrylic Tubs.
Author: george 7941 (Canada)

I have been using GE Advanced Silicone (neutral cure) but the bond between the silicone bead and the acrylic only lasts for about two years.

I remove all of the old caulk, sand the acrylic to roughen the surface and wipe down with rubbing alcohol.

I try to avoid caulking jobs because they are tedious and time consuming but when a customer calls me in to find out why the shower is leaking and I find the silicone has separated, I don't want to tell the customer at that point to get someone else to do the caulking.

Googling turned up recommendations to use siliconized acrylic latex caulking.
Anyone have recommendations?

whatever you use, fill the tub with water before you caulk.

Do you fill just acrylic tubs before caulking or do you fill enamelled steel tubs too?

If, repeat IF, the tub is PROPERLY set on a PROPERLY installed ledger board there will be NO separation at the caulking because of the weight of the water.
