Various adhesives are used for working with tiles. All of them are distinguished by separate characteristics, the manufacturer and the price. But if it comes to exterior decoration of the structure, first of all you need to focus on frost resistance of the glue, resistance to low temperatures. Otherwise, the tile will literally fall off in the first cold season.
Before buying a product, you need to read all the items on the packaging. The Conscientious Manufacturer places all the information necessary for the Buyer. If it only contains general information, there is no adhesive composition, specific application, it is better to choose another product.
What to look for
- Application conditions( resistance to sudden changes in temperature and its maximum "minus" values).This indicator often causes confusion. The temperature at which the glue reliably "holds" the tile after gluing and the limiting, allowing to conduct finishing works - is not the same.
- Composition setting time. If it is minimal, this, on the one hand, will increase productivity, but on the other hand it will complicate the alignment and correction of the sample position. Therefore, only a professional who can observe the extreme accuracy of the masonry can apply this glue.
- For what type of tile adhesive is intended.
- On which surfaces can be applied( base material).
- During which time the applied frost-resistant adhesive is able to adhere the tile. On this depends on what size the surface can be pre-treated with a mixture, and then make a fixation of the samples. The more it is, the faster the styling speed.
- The "viability" period of the diluted mixture. This is determined by the time of its suitability after cooking.
- Features of use. When decorating surfaces there are various difficulties. For example, tiling in some places can only be done from the top down. Not all adhesives allow to make laying according to this procedure( depends on the degree of thixotropy of the composition), because the tiles should not "slide".
- Maximum thickness of the adhesive layer. For massive tiles, this figure should be greater.
What to take into account
- The consumption of the adhesive, declared by the manufacturer, is not the most accurate indicator. It is calculated proceeding from the fact that all the conditions for the preparation of the basis are fulfilled - leveling, preliminary impregnation. In practice, as a rule, it is required more. After all, the surfaces that are lined are from different materials. The more unevennesses on them, the more porous structure they have, the higher the consumption. Therefore, you need to buy glue with some margin, about 15 - 20%.
- Based on this, it is worth familiarizing with the period of suitability of the composition. If it is sufficient, then the surplus funds can later be used for "spot" repairs, rather than buying glue again.
-
Surfaces of porous materials( for example, cellular concrete) must be carefully primed, and in several "approaches".This will significantly reduce the absorption of the adhesive and reduce its consumption. - To use universal adhesives for outdoor applications, you need with some degree of caution. As you know, there is no cure for all diseases. Even if the Instruction for use indicates that such a compound is used anywhere, then it is worth asking - is it another regular trick of "cunning" marketers? And they took into account the peculiarities of our climate( if the products are imported)?Glue, which is successfully used, for example, in Europe, we may find it ineffective.
- It is advisable to purchase ready-made glue, not a dry mix. Firstly, the exact ratio of components can not be exactly maintained if the composition is to be diluted as necessary, in portions. Secondly, the effectiveness of the adhesive is largely determined by the quality of mixing ingredients, and this creates additional complexity in its self-preparation.
- If after finishing the surface after a while the tile will fall off, and even fall from the height and at the same time split, the repair will "pour out" in wasting time and money. From this point of view, you should not save on the adhesive.
Pin
As an example - the popular frost-resistant adhesive for tiles "Ceresite CM11", which costs about 90 rubles per 5 kg package. It is applicable in any region, since the temperature range is from -50 to +75 0С.But the finishing is carried out only in a warm time - not less than at +5 0С.This once again proves that the choice of glue is made individually, taking into account all the features of installation and climatic conditions in the place of residence.
