We Once Saw Someone Use Toothpaste as Filler… Please Don’t Be That Person, DIY Fails
April 1, 2025by Clive SanhamUncategorized0
April Fools’ or not, we really did see someone try to patch a wall using toothpaste. White paste, smooth finish, minty fresh—what could go wrong, right? Well… pretty much everything.
In the spirit of April Fools’ Day (and some good-natured DIY roasting), let’s take a look at one of the most jaw-dropping “fixes” we’ve ever encountered. And hey, while we’re here, we’ll drop some real advice so you can avoid becoming the next #DIYFail.
The Legendary DIY Fails: Toothpaste as Wall Filler?
Okay, so here’s the scene.
We were called in to look at a “minor repair” in an older property. The homeowner sheepishly mentioned they’d “patched it up” temporarily. We walked in expecting a bit of putty work or maybe some dodgy caulk. But no… the sweet scent of mint hit us before we even saw the wall.
Toothpaste.
Thick globs of it, smeared into cracks like it was Polyfilla from a Colgate tube.
To be fair, it was neatly done. Smooth even. And white. But structurally sound? Not even close.

Why Toothpaste Is NOT a Filler (Besides the Obvious)
We get it—everyone loves a life hack. TikTok and YouTube are full of “quick fixes” that look amazing in a 30-second video. But there’s a reason professionals don’t carry toothbrushes in their toolkits.
Here’s why toothpaste is a terrible choice for wall filler:
-
It shrinks as it dries, leaving gaps.
-
It cracks and crumbles with the slightest vibration or movement.
-
It’s not paintable (unless you enjoy blotchy blue stains and fresh mint odours).
-
It attracts moisture—cue mould and mildew. Yum.
-
It’s a magnet for dirt—your walls will look like they’ve been sneezed on by a candy cane.
In short, it might look okay for a day or two, but that’s where the magic ends.
Real Advice, No Nonsense: How to Actually Fill a Wall Crack
Here’s how the pros (ahem, like us) get it done:
1. Assess the Crack or Hole
Not all wall damage is equal. Hairline cracks? Easy fix. Gaping holes from a poorly thrown dartboard? Bit more work.
2. Use the Right Tools & Materials
You’ll need:
-
Filler or joint compound (ready-mix or powder)
-
Putty knife or filler knife
-
Sandpaper (medium and fine grit)
-
Primer and matching paint
No toothpaste. Ever.
3. Apply Like a Pro
-
Clean the area to remove dust or flaking bits.
-
Apply filler in smooth, thin layers.
-
Let it dry completely—no rushing.
-
Sand until it’s smooth as glass.
-
Prime and paint.
Voila! Your wall is now guest-worthy, not giggle-worthy.
What to Use Instead of Toothpaste (Seriously)
Still tempted by the convenience of a bathroom cabinet fix? Here’s what to stock up on instead:
-
Spackle or Polyfilla – Great for small holes and cracks.
-
Joint Compound – Ideal for drywall and larger patches.
-
Caulk – Perfect for sealing gaps along trim or windows.
-
Wood Filler – If your issue is with wooden surfaces.

The Hidden Cost of DIY Fails
Look, we’re not trying to shame anyone (well… maybe just a little for laughs). We’ve seen it all—duct tape gutters, expanding foam in door hinges, even foil used as insulation.
But here’s the deal: these quick fixes usually end up costing more in the long run. What could have been a £5 repair becomes a £500 fix after the damage spreads.
So if you’re unsure, do yourself a favour—call in the pros. We’re not just builders. We’re problem-solvers with a mean sense of humour and a love for a good restoration story.
