I have an Everhard / Nugleam laundry trough with a fine crack, leaking.
The install for this was *ugly* and I reckon that would void the warranty. The plumber did their utmost, it is an old house which had some awful renovations, and no sensible maintenance. I needed a functional laundry. This was the most urgent fix I needed in my first home, and I have some regrets about how nice a basin I purchased while galvanised and cast iron pipes were coming out of the walls (that location was fashionable in the days when people also ran gutters inside eaves to downpipes). The room still has a badly done kit floor. The wall behind the trough has white corflute nailed there so I do not go insane with all the holes that just need to wait.
The fine crack in this polymarble trough - I think I did, probably dropped something, I thought it was a scratch. The 'scratch' became longer over time. Photo of that is attached. More interesting are the underside photos. The line seems to follow that crack, and it is surrounded by 'white stuff.' The stuff does not leave much trace on a black glove. What happens is that water left in the trough will slowly seep through and it becomes 'wet white stuff.' Eventually it will be enough to start dripping. If I squint and try logic, the crack lets water leech something out of polymarble once the top finish gets damaged.
An online search for "polymarble repair" leads me to epoxy paste. From there - I can't find an obvious tutorial.
As with my bathroom bench post - I can handle a repair not being pretty, so long as it is functional.
Hello @LynneWasTaken
I propose using PC-11 56g White Epoxy Paste to cover the crack. I suggest mixing the putty very well in your hand and forming a long cylindrical strip with your fingers. Place the putty over the crack and press down with your thumb. Gently feather the putty with your thumb so that it spreads out covering the crack. Do your best to keep it smooth and uniform, please note that the putty will dry to an off-white colour and will not match the existing colour of your trough. Double check that the entire crack has been covered, I then recommend using Rust-Oleum 13.3ml White Tub And Tile Touch Up Kit to touch up the surface of the putty once it has fully cured.
Please remember to wear personal protection such as disposable gloves when using the putty.
If you need further assistance, please let us know.
