Plaster the dowels

It often happens that dowels do not hold as they should. Quick then a supposed solution is found: the plastering of the dowel. Basically, this is quite a correct approach. But still the idea could be implemented better and above all safer.

If the dowel does not hold...

Who wants to put dowels in the old building, knows the problem depending on the building fabric only too well. But even with brick and stone walls can cause problems and fail a dowel hole too large or not hold the dowel.

... that can also be due to the structure of the building

However, this does not necessarily have to be due to the structure of the building. You may also be using a wrong dowel or disregarding other factors such as dowel sizes, dimensions and other features such as the proper dowel types.

Errors while drilling are also possible

But if it is the building substance, there are also different effects:

  • Dowel hole drilled too big
  • Building substance not drilled, but knocked out by pressure, impact and / or wrong drill
  • Building substance sandy

Now, if you take a closer look at a pack of gypsum, you may notice that it may also read "suitable for dowels" or something similar on the package. In fact, you can attach a dowel reasonably well in the wall. But the plastering of a dowel is rather a makeshift or not suitable for every challenge.

Plaster is pretty sensitive

If you just want to hang a simple, not heavy picture, the casting is likely to be relatively straightforward. But even here we have to restrict. To such a situation it comes most likely in an old building. And here is the high probability that the building substance has a relatively high humidity.

However, as you may know, gypsum draws moisture. Thus, the strength of a plastered dowel under the prevailing humidity in an old building can be significantly limited. If you really want to be sure that the dowel really stays in the wall, ceiling or floor, you should use modern products.

Instead of plastering the anchor in concrete with synthetic resin

For this purpose, it is recommended to embed a dowel. For this purpose, you can purchase in the specialist trade liquid, chemical or injection anchors mentioned products. For this purpose, a special synthetic resin mortar is injected into the dowel hole, which hardens within an hour and then holds securely in any case. Because it is not a conventional dowel so that it is cast in concrete, but an anchor sleeve or the associated threaded anchor.
