Briefly hit a nail into a wall or a drilled dowel hole and then it happened: a fist-sized piece of plaster has sailed from the wall, leaving behind an ugly hole. Even when you move out, if all shelves and images are suspended, so resembles some wall a holey cheese. What now? We’ll tell you how to holes and rips fast and clean again and which fillers for what purpose are suitable – the best tips for filling and backfilling .
At the latest when the renovations are small cracks and holes in plaster and masonry must be sealed, because they not only look unsightly, but can not be too easy on paper untreated. Before perk is it happening primed, once the nature and cause of the fault must be detected.
Indoor or outdoor
Depending around the damage is, different fillers and tools are used. Basically, there are flaws in the outer region to be distinguished from the interior. Since masonry and plaster are exposed to the weather outside, only waterproof plasters may be used to here.
Hairline crack or dowel hole
In general, it is in damaged areas to hairline cracks or old nail holes and dowel. These can be painted in the ideal case and paper inside also. The paint or wallpaper then covered just the little damage. A better way is to seal the holes. For this is the best instant gypsum in the tube with spray top is touched ready to buy at the hardware store. Since Instant gypsum to lose density during drying, the handyman but must fill a second layer after some time, advises Michael Pommer of the school DIY DIY Academy in Cologne
Toothpaste closes holes in an emergency
If time is of essence – for example, in an excerpt – you can seal with a dab of toothpaste, the holes also. However Pommer does not believe in this solution. “That’s botched job, a purely visual story,” he explains. Even chewing gum as a filler warns the construction engineer: “This is unhygienic and the worst thing you can do.” Because gum is a food on the mildew and other fungi can spread over time. The material dry out and also can rip. As long as the gum is sticky, he put on dirt – then you have at some point a brown spot at the site.
If the damage too great, it can be shut indoors with gypsum plasters or preformed filler. The structural engineer recommends a so-called two-component putty. The downside: The resin in the dough could irritate the skin. When processing latex gloves should be worn. Modelling clay and plaster can be drilled later.
Of cement, however he does not recommend “cement plaster is always dark in colour and grainy, there may be problems when over-painting..” Wall colour could not cover the dark cement may and its grainy surface prick out against a smooth wall. For outdoor use cement mortar, however, is a good choice.
Fill expansion joints elastic
For joints in the interior between adjacent components, such as when connecting drywall to a timber framing, an elastic joint sealant must be used. This can for example be acrylic, that is pressed on a device in the gun column. Thus joints remain closed even with slight movements of the components. If you want to paint over the acrylic joint with the matching wall colour, should pay attention to the reported paint compatibility. However, the need wall colour show elastic properties, otherwise they later broken in the region of the joint.
