The toilet paper holder in the bathroom was loose because the holes in the wall were crumbling, and too big for anchor plugs. I used bigger plugs, but that only made the holes bigger. I wasn’t sure how to fix the problem, so the holder remained loose for a few years, much to the consternation of my wife and daughters.
I stumbled across a product called Wetnfix, designed to “secure wall plugs in problem surfaces.” I had my doubts it would work but I thought it would be worth a try.
It comes with 20 cotton mesh discs treated with gypsum plaster.
I dipped a disc in a glass of water and wrapped it around a wall plug (not included). Actually, I used two discs per wall plug because the holes were so large.
Then I stuck the plugs in the hole and tapped them with a hammer until they were flush with the wall. A few minutes the plaster was set and I fastened the toilet paper holder to the wall.
It worked! I suspect it’s likely to hold, at least until my nephew stands on it so he can look out the window.
