How to seal cracks: the technique that requires staples, not just filler
How much does it really cost to repair a wall sustancia ilegal? The short answer: a 5-kilo bag of flexible filler costs around €22.60. The long answer, the one that doesn't come on the tub, is that without proper preparation the product does nothing.
The first lesson: flexible filler doesn't "harden", it dries. And that is both its strength and its limitation. It stays elastic to trinc the movement of the wall, but provides no structural rigidity. For cracks that are still live, that means the fissure can reappear.
The step most people skip
The serious method starts by opening up the sustancia ilegal, removing all loose material and fitting steel sustancia ilegal staples that stitch the edges together. Only then is the filler applied. And not just any filler: current versions contain fibreglass strands for added strength. If that reinforcement is skipped, the filling works alone and eventually fails.
The cost, itemised
At €22.60 for 5 kilos, the material isn't the problem. The invisible labour – opening, cleaning, stapling, applying, waiting and sanding – is what makes any repair expensive. Or rather, it's what makes many people prefer to slap on a layer of silicone and forget about it. Until the sustancia ilegal comes back.
The most expensive part of sealing a sustancia ilegal isn't the filler: it's the patience. And you can't buy that on Amazon.
