Bulk floor Knauf (Knauf)

It poured a room of 20 m2 with a layer of an average thickness of 0.5 cm, in places up to 1 cm. It was flooded quite quickly, the surface was carefully leveled. And during drying, he went cracks and bubbles. After drying, I picked up a little spatula near the door and chopped off a piece by half a square no less, so in 30 minutes I poked out half of the room, and the rest had 10 minutes of perforating.

But the fault in this is completely mine, I admit, I covered the base with a primer only once, and even then I took the cheapest of Leroy. The second time I covered the floor 2 times with Ceresite TST17 with a pause of 4 hours for complete drying. And only after that was the Knauf-tribone flooded. This time there were few bubbles in only two places around the edges. It has been already 3 weeks, without cracks and chips, I will soon lay down the laminate.

dries fairly quickly, gives an even, durable layer, easy to work

very demanding on the preparation of the base, it is impossible to save on the primer

To make the screed self-leveling floor Knauf yourself and without bumps is real only in small areas. If you fill in by markers or in separate sections, then there will be bumps in any. I have tried repeatedly. As a result, my best work from the whole apartment is a 9 m loggia. The screed on the loggia open to all winds without additional covering with ceramic tiles (it was planned so that all hands do not reach) has been standing for the third year and does not crack.

It is convenient to apply to a small area;
Blurs quite well itself;
Gives good thermal insulation;
Gives a strong layer;
Frost resistant.

quite high cost per bag and expense.

5 years ago, I poured the floor with a leveling mixture in my parents' apartment. This year he did the same in his apartment. The result was extremely dissatisfied, starting from the process itself and ending with the result.
Firstly, it is not known why the mixture began to spread poorly, it was necessary to distribute it with a spatula, and only then roll it with a needle roller;

Secondly, it dried out longer, and much more. If the first time after 3-4 hours it was possible to advance carefully, now there is not enough day;

Thirdly, now in the dry mixture there is a lot of filler of large fractions, which prevents the mixture from rolling normally on the floor.

And all this considering that the cost of one bag has increased significantly. The manufacturer is our Serpukhov Knauf factory.

The fill, when it finally froze, gave an even and fairly strong layer.

Dear, dries for a long time, is difficult to distribute.
