When it comes to the permanent joining of elements, there was a long time on the construction only nailing or screwing. Both damage the components to be connected. If a connection is to be made without drilling holes or nails, gluing is a new alternative. Read in this text everything you need to know about fixing with mounting adhesive on the construction.
In your own home, drilling is still relatively easy. Except that you should pay attention to electricity, gas, and water pipes, you do not have to pay much attention here. For leased apartments but it looks very different: Each hole must be filled again on the move and painted over, otherwise threatening to sensitive deductions on the deposit. That is why in rental housing should always as little as possible, the drill is used. Of course, there are places where their use is inevitable: When hanging kitchen cabinets, bathroom mirrors and ceiling lamps, it is not without the drill. However, you should always look for existing holes. These are not only easier to drill, you do not damage the wall again by reusing them.
In many cases, but instead of the drill, the adhesive can be used. The funds available today are so strong that they are also suitable for demanding tasks.
Advantages and disadvantages of glue
Adhesive connections are easier to handle and cleaner than drilling and nail connections. They cause no dirt and no destruction of the components to be connected.
However, adhesive bonds have only a limited carrying capacity. They are usually quite sensitive to shock loads. Even adhesive joints must be removed when moving out. This can be a big challenge, depending on the terrain.
Pictures, hooks, mirrors and more
Gluing installations in a home is today in many cases an interesting alternative to drilling. Especially in the field of repairs, the adhesives of today are capable of astonishing performance: Splintering in window sills, detached tiles or even fallen pieces of plaster can be repaired with the right glue again. It is important to first get an overview of the different types of glue.
Repair and assembly adhesive
Assembly adhesives are:
- hybrid polymer
- Dispersion and water based adhesive
- Polyurethane structural adhesives
Hybrid polymer adhesive
The hybrid polymer mounting adhesives are plastic adhesives that have been enriched by another component. Plastics, the so-called polymers, form particularly long-chain molecules. By internal knotting and by penetration into the surfaces of the elements to be connected, they can produce particularly stable connections. However, they are not necessarily dependent on absorbent surfaces. A typical example of a hybrid polymer mounting adhesive is the plasticine-like silane.
Hybrid polymer assembly adhesives have the following properties:
- They do not need absorbent surfaces
- They do not disappear on curing
- They form a waterproof surface, so they can be used for inside and outside
- They can be used as adhesives and fillers for columns up to 20 mm wide
- They can even be used on damp surfaces
- You even have some flexibility in the splice
However, the hybrid polymer assembly needs sufficient contact with the outside air. If this is not given then they will never cure properly. The splice will sooner or later fail.
Adhesive based on dispersion and water
Dispersion is a term that is known above all for the wall paint for interiors. The bulky term, however, means nothing more than a "broad and fine distribution". A well-known dispersion adhesive is for example the wallpaper paste. He is very well suited for light but flat liability. But he needs to have certain conditions.
- Sufficient air for setting
- Sucking surfaces on both materials
For this, the dispersion adhesive offers the following advantages:
- Washable with water
The disadvantages of dispersion adhesive are:
- Heavy loss
- Very rigid connections
- Not suitable for outdoor use (dissolves immediately upon contact with water)
PU materials or PUR are all hard foam boards such as Styrofoam or Styrodur. They are light, easy to work with and practical - but extremely demanding in terms of adhesives. Most of the adhesives do not last on them. Some may even etch deep holes in the plates. Therefore, only the special PU adhesives are allowed for the bonding of rigid foam elements.
First of all, PU foam in turn sticks very hard before curing. The mounting foam, with which the frames of windows and frames of doors are sealed is therefore even suitable for adhesive joints. In addition, there is also the special PU adhesive. He is usually offered in the spray can. PU adhesive is suitable for all foamy and foamy materials. These include mattresses, floorboards, ceiling panels and much more.
PU mounting adhesive
PU adhesive develops its adhesive power only over time. Therefore, the elements to be connected must be fixed for the duration of curing. In addition, its adhesive force depends on the contact pressure. This is always a special challenge with foam and rigid foam, because you should not damage the elements by pressing.
However, he cures quite fast. Efficient work is thus well possible. PU adhesive is also resistant to water and weathering after curing. He can also be used well in the outdoor area. The only problem is direct irradiation by sunlight. Unfortunately, UV radiation can not tolerate PU adhesive well. He dissolves.
PU glue also foams something. Although he does not disappear, but he expands for it. As a rule, this is harmless for processing.
Other assembly adhesives
For the chimney inner pipes of chimneys, a special stone glue is used. He cures extremely strong. This adhesive is also ideal for all other mineral compounds. Wherever stone is to be glued on stone, the fireclay glue is the means of choice. With it, both inside and outside tiles, clinker and natural stones in a great way permanently reconnect. However, he is really only useful for this one purpose. You can not glue metal or plastic with it.
Application of assembly adhesive
The most important thing when gluing elements is that the splices are clean and dry. Dust, moisture and grease greatly reduce the adhesiveness. Therefore, a lot of time and care should be used in the preparation. Whether the surfaces have to be roughened depends on the adhesive used. Finally, the elements must be fixed during bonding. The gluing is a critical moment, since the adhesive effect sets only gradually.
It is particularly important to adhere strictly to the processing regulations. You can, depending on the adhesive, very different from each other.
With mounting adhesive you should pay attention to brand quality. The prices can be a bit higher. But one has but the performance, which one hoped for.
Usual prices for quality assembly adhesives are:
- PATTEX mounting power glue: Prices from 5-7 euros per cartridge with 370 grams of for use inside and outside. The prices may have a surcharge for shipping costs when buying in online trading.
- Metylan wall & ceiling mounting adhesive: Prices from 2 euros per cartridge with 370 grams for the application indoor.
- Bostik GmbH Bostik Stone Adhesive CEM Cement Mortar: Prices from 25 Euro per 2.5 kg bucket. Application for all stone and tile repairs inside and outside.
- Zwaluw PU stone glue: Prices from 11 Euro in the 750ml spray bottle.
At least on the day of the excerpt you have to worry about removing the glue. This is not so easy, after all, the glue was applied for the purpose of permanent bonding. There are two options:
- Mechanical detachment of the old adhesive
- Chemical-thermal detachment of the old adhesive
In the mechanical removal of the old adhesive scrapers have proven. Very effective tools here are, for example, the Ceranfeld scraper, which is used for cleaning ceramic and induction hobs. They are particularly suitable for removing residues on smooth surfaces such as tiles, tiles or painted metal surfaces. In the glazed surfaces of tiles or tiles you get with a little skill the old adhesive residue-free. For painted surfaces, it is usually necessary to repair the paint.
Sprayed PU adhesive can be cleaned well chemically with adhesive remover. A commercial remedy is "Dr. Protection PU cleaner ". Prices start from 7.50 for the 750 ml bottle. When applying, wear gloves and a light mask. After all, it is an aggressive chemical.
Dispersion glue is the easiest to remove: It is water-soluble and can easily be washed off.
If cement-based adhesive is used during stone repairs, the dreaded cement streaks can occur. These are treated with cement stain remover. When using it, acid-resistant gloves must be worn. The prices start from about 7 euros for a 5 liter canister.
Connecting with reason saves trouble and costs
With some expertise and predictive planning you can keep the damage caused by connections very small. For example, in the bathroom you should always follow a rule: Always drill into the joint, never into the tile. Ideal are the crossing points between four tiles. There, the drill has the most space. Otherwise always make sure that the drill is narrower than the joint. When pulling out, you can simply fill the hole again - done.
