What are the advantages of CMC wallpaper glue, its varieties and manufacturing standards: Tips + Video … pay attention to the color of the dry matter.

If all the GOST standards were observed during the manufacture of the adhesive, the powder will be white. In this case, you do not have to worry that during the preparation of the solution, an inhomogeneous mixture with lumps or sediment is formed.

Do not purchase yellowish glue. Often, the composition acquires such a color if the manufacturer saves on manufacturing technology, does not adhere to standards and specifications. It is strongly not recommended to use such glue, as it can lead to unpleasant consequences.

For example, yellow stains may appear, which cannot be eliminated; over the pasted wallpaper and repairs will have to be redone.

! Important. The process of creating CMC glue is regulated by the technical conditions TU 2231-034-07507908-2001 and TU 6-55-40-90.

If we evaluate CMC by its ability to glue wallpaper to the surface, we can distinguish three main types: for light, heavy and medium wallpapers. The main active substance, sodium carboxymethyl cellulose, gives the solution its thickness and stickiness.

The more it is in the composition, the thicker and more sticky mixture that will hold on the wall, including heavy vinyl wallpaper, can be prepared.

Advantages of CMC glue

How does CMC differ favorably from other wallpaper adhesives?

  1. This universal glue.It will not be difficult to dilute the dry substance to a ready-made solution, and additional antiseptic additives will save your repair from the formation of mold.
  2. Ready-made mortar is easy to use for wallpaper installation.
  3. The glue does not have harsh, unpleasant odors.

  4. Due to its composition, the probability that spots or streaks appear on freshly pasted wallpaper is reduced to zero.

Today, many manufacturers present their products on the market of adhesives. Both domestic and foreign. The advantages of the Russian-made CMC glue, undoubtedly, include a low cost. On the other hand, the time that the mixture is ready for a ready-to-use solution is about two hours, which does not contradict GOST standards.

As for wallpaper glue from foreign manufacturers, the disadvantages include the high cost compared to Russian counterparts, but you will overpay in time, since less than a quarter of an hour after the dry matter is diluted, you can already start gluing wallpaper.

! Important. The most famous manufacturers of CMC glue in the Russian Federation are OOO TC Vympel, OOO Zavod Karbocel, OOO Omega and others.

Application

Even if you will dilute the glue solution for the first time, this will not cause you any difficulties. Prepare in advance the dishes in which you will prepare the glue, preferably enameled.

Carefully read the instructions on the package. Please note that each pack must indicate how much water is needed. Often, for thin wallpapers for 0.5 kg of powder, about 8 liters of water are needed, and for heavy ones - about 7 liters.

Slowly pour the powder into water at room temperature, stirring constantly.

After everything has been thoroughly mixed, leave the solution for swelling (the waiting time for readiness is also indicated on the package).

! Important: Select CMC for the type of wallpaper that you will glue. 0.5 kg of dry matter is enough to wallpaper a surface of 50 sq. m .
