Tonkoslojnaja plaster

About one kind of plaster - tonkoslojnoj which was widely enough applied by Muscovites in the late fifties - the beginning of 60th, but has been very soon forgotten.

The Essence of this method in the following. In the thickness no more than 10 mm put tonkoslojnuju plaster directly on brick and concrete surfaces.

At once there can be a question: how, at once? Even without beacons? After all we, as they say, "ё фх=ё=тр" we know a rule: oshtukaturivanie without surface alignment it is supposed provided that the basic designs (walls, ceilings, partitions) have deviations from correct position: no more 1:100 heights for a surface in buildings; for ceilings a deviation from a horizontal no more 1:200 the premise parties (lengths or width).

Yes, the split-hair accuracy is required. But it is achievable. It is the first masons existing then in Moscow of trust have proved in 1956 Moscow system N 10. And is not simple to flash the skill. Tonkoslojnaja plaster bears variety of sure gains. Here that representatives of Gosarhstrojkontrolja wrote then about it: "Кх§эюыюуш  undoubtedly progressive... There is a laying of 6th floor, and on the fifth preparation for colouring already approaches the end... A quality Laying, deviations - millimetres... At norm of 8 m 2 in change shtukatury give 20 m 2 . Work by means of a nozzle - and spend twice less solution. Air permeability of walls in the Zraza is less, than at usual =х§эюыюушш".

But at once opponents of a method had a following question: "+ how to be in the winter? After all more low 0°Р shvatyvanie a solution яЁхъЁрЁрх=ё ". And it have answered in trust the Moscow system № 10. Entering into a solution potash (carbonic kaly), they received the necessary plastic weight which after thawing gave a strong covering.

Here what councils were left by them to us. Concentration potasha in a solution depends on air temperature. At a minus 10...12°Р take 3%-s' solution potasha with density on areometru 1,024. The more low the temperature, the a solution potasha has the big concentration (it the laboratory defines).

Difficult cement-limy solutions with cold-resistant additives prepare on portlandtsementah and shlakoportlandtsementah marks 300... 500. Structure of cement-limy solutions 1:0,2:4. It is not recommended to apply putstsolanovye and magnezialnye shlakoportlandtsementy - they extremely slowly seize.

The Laying was conducted usually by way of freezing of a solution. For preparation of a solution sand warmed up to 20...25°Р, water took from a boiler with temperature 27...30°Р. For a day shift potash it is better to prepare since evening that its crystals were properly dissolved.

Walls before solution drawing carefully cleared from naledi and a dust. Zatirku made through 20... 40 mines after plaster coat drawing.

Tonkoslojnaja plaster was conducted with backlog on 1... 2 floors from a laying that provided the necessary front of work.

There was also a third argument at opponents of a new method: "О=ю it? Returning to becoming obsolete wet яЁючхёёрь?" Just for 50th years universal introduction "ёѕ§ющ" is necessary; plasters.

What on it to tell? First, and in forty years it is impossible to name monolithic plaster the become obsolete method. Secondly, tonkoslojnuju the coupler hardly can be carried to wet processes. And, thirdly, tonkoslojnaja plaster before "ёѕ§ющ" too has the advantages. For its manufacture are not necessary tepljaki, constant heating of premises. For "ёѕ§ющ" plasters the air temperature not more low 12...14°Р.

is necessary

Now, when again build buildings of a brick much, from concrete blocks and even from monolithic concrete, tonkoslojnaja plaster can be useful. Speech not about concrete panels of full factory readiness where really shtukaturu on a platform there is almost nothing to do. Tonkoslojnaja plaster has not found wide application mainly because of our vicious habit a little to think of quality of the work.

Tell to other mason that it observed millimetric accuracy at a laying, he only will grin. But it would be desirable to believe that similar "тхёхыіёръют" in due course becomes ever less, professional pride, the present skill will return to all working people. Then and tonkoslojnaja plaster will take the place put to it. As after the first experiences of thirty-year prescription scientists have brought the new data in method working out. Their councils I result more low.

Prepare a plastic solution on small sand. A solution filter through a sieve with apertures 1,5Х1.5 see At a thickness nameta to 7 mm it put on a plane at one time, carefully level and smooth down. At a thickness nameta 10 mm put a solution in two steps - obryzg and a ground.

Concrete and gipsobetonnye surfaces level and fray polimertsementnym a solution. At continuous alignment of a surface at first fill seams between panels polimertsementnym a solution, then put a layer of this solution in the thickness of 5 mm, level, rub clean.

Before drawing of a solution of a surface it is necessary ogruntovat 7%-s' structure polivinilatsetatnoj to a dispersion.
