Plaster today is becoming the basis for many building materials. It can be glue or tile products . They will be discussed in the article. The information presented below will allow you to understand what types of gypsum glue exist today, as well as which composition for laying gypsum tiles is better to use. It is important, before starting work, to learn more about what technology is necessary to act on.
Varieties of gypsum glue
Gypsum tile adhesive is usually available as a dry powder. This type of mixture is the most successful. To increase the adhesion to the ingredients, special substances are added, in addition, they allow you to work with glue without rushing. If you wondered what to stick gypsum tiles to, it is worth paying attention to another variety of such families, which provides for the need to use quartz sand. It is added to reduce the cost of production. In expensive glues, this ingredient is either small or not at all. Depending on the amount of additives, specifications may vary.
The main task of the adhesive is strong adhesion to the surface. Another variation of the described composition has an increased volume of gypsum. This also affects adhesion. This quality is also determined by the volume of water that is used to dilute the powder. The amount of liquid is usually indicated on the package. If you learned from the instructions that for 1 kg of glue 300 ml of water will be needed, then it can be argued that gypsum in this composition is small, while there are many fillers. From this it follows that in this type of glue the adhesive ability will be reduced. In this case, the glued material may peel off during operation.
Features of choice
When choosing glue, you need to remember the ratio of water to gypsum. A rather important indicator is the setting time of the mixture. If the glue is good, then this period should be less. Depending on this indicator, the pace of work that you will need to adhere to for bonding the material is determined.
Gypsum tile adhesive usually retains its ability after dilution for an hour. This does not mean that after application to different materials the shelf life of the mixture will remain the same. Each manufacturer has its own indicator. As practice shows, the minimum period is 30 minutes, while the maximum is 70 minutes.
Reviews of gypsum adhesives from different manufacturers
If you need gypsum adhesive for a tile, then you may prefer “Volma installation”, which basically contains gypsum, chemical impurities and modified additives. In the role of the main advantages of this mixture, buyers note water-holding characteristics and optimal working hours. That is why this mixture is chosen by consumers quite often.
It can be used at temperatures ranging from +5 to +30 ° C. In this case, optimum humidity should be maintained. Customers like the adhesive to bond well with plaster, concrete, gypsum products, aerated concrete and foam concrete blocks, masonry, gypsum sheets and drywall.
According to customers, the Knauf-perlfix glue is also quite popular. It is implemented in the form of a powder, and in this case the additional binding elements and astringent gypsum act as the main binding components . Buyers emphasize that you can use this composition when conducting internal work.
Features of using Knauf Perlfix
If you decide to purchase the gypsum tile adhesive described above, you should familiarize yourself with the features of its use. Before starting work, the base is prepared, for this it is cleaned of contaminants and the protrusions are removed from the surface. If the walls absorb moisture well, as for aerated concrete, silicate, ceramic elements and plaster, then the surface should be pre-treated with a primer, you can use "Concrete contact".
These procedures can improve the adhesion quality of the surface. The base must be left to dry, only after you can proceed to further work. It is important to keep the primed surface clean.
Gypsum Glue Making
To mix the powder with water, it is necessary to use a plastic container into which pure water is poured. Adhesive should be gradually added to the liquid, mixing the composition with a construction mixer. Ultimately, you should get a creamy consistency without lumps. It is not recommended to add other components to the solution. It is important to ensure that the mixing container is clean.
Adhesive technology
After you figure out which glue for gypsum tiles to use, you can begin to work. The composition is applied to the wall, and then to the surface of the tile. Products will need to be pressed to the surface and set the level by tapping. If the base has recesses greater than 2 cm, then they must be covered with drywall using the same glue.
When gluing insulation material, it must be wiped with a Knauf-perlfix solution. After completion of work, the tools are washed under running water. Before going to the store, you must definitely calculate how much mixture will be needed. When solving this issue, it is necessary to be guided by the manufacturer's recommendations. From them you can find out that for one square meter of surface you need about 5 kg of dry powder.
Can tile be laid on gypsum plaster
Quite often, home masters ask themselves whether it is possible to glue tiles on gypsum plaster. The answer is yes, but the basis must first be prepared. This is due to the fact that surfaces need to be given quality with increased adhesion and strength, to reduce the water throughput of the material, and only after starting to lay the tiles.
It is important to take care of the alignment of defects. For the reason that a thin layer of glue should be used for laying, chips and potholes should be coated with plaster. It will be possible to work with such a surface after it has completely dried. Walls are recommended to be treated with an antifungal compound.
Do not lay tiles if the layer of plaster has not been primed. This stage is the most important to achieve a positive result. If you also faced the question of whether it is possible to glue tiles on gypsum plaster or not, then you should first familiarize yourself with the functions of the primer. It can not only reduce the porosity of the material, but also increase the margin of safety of the coating. The primer will eliminate the ingress of moisture inside and will positively affect the adhesion quality.
Gypsum tile adhesive
In the modern variety of building materials you can get lost. However, the recommendations below will help you understand which composition is best used for gypsum tiles. A powder mixture based on quartz sand and gray cement is PLUSFIX glue. Among its ingredients, cellulose is also present. This mix is great for small tiles. Work can be carried out on the following surface types:
The glue described above and the composition called LITOKOL K 17 are very similar in characteristics. The last of them consists of quartz sand and Portland cement, the first of which is presented in granular form. This mixture is used for gluing large-format tiles. A mixture of mineral aggregates, gypsum and high-quality additives is Satyn PKG-28 glue. The ingredients give the composition high ductility.
After preparation, the mixture will remain viable for 50 minutes. Another composition on a gypsum basis - "Plaster". It seizes quite quickly, and the remains can be removed from the surface with a sponge previously moistened in water. If you can’t pick up glue for gypsum tiles under a brick, then you should pay attention to the material "Monte Alba". It is used exclusively for interior work and is ideal for plaster cladding.
The process of laying gypsum tiles
Before starting work, you must also figure out how to glue gypsum tiles to the wall. On the surface you need to apply a little glue with a thin layer, the product is then pressed against the wall, within a few minutes it will be possible to adjust its position. To align the seams, you can use plastic spacers.
The solution protruding from the seams should be immediately removed with a rubber spatula. Otherwise, it will be impossible to work with the composition. Before starting repairs, it is imperative to understand how to glue gypsum tiles to the wall, tips about this are presented in the article. For example, you should not dilute too much solution, because if you do not have experience, then it will quickly harden, which will cause unjustified expenses.
