AT repair work oh putty is one of the most common building materials. Before the advent of drywall, it was used to level walls, and after that it was used to finish sealing joints in gypsum board structures. For this purpose, the Knauf brand offers Uniflot putty, in the manufacture of which the manufacturer selected specifications for drywall work.
Knauf putty is made from finely dispersed gypsum, to which polymer additives and impurities are added to change color. Mixture characteristics:
- Layer thickness: minimum 0.1 cm, maximum 0.5 cm;
- Solution consumption: 0.3 kg is spent on processing the ceiling, and 0.5 kg on partitions.
- 15 mm maximum fraction size;
- Strength: 5.2 MPa for compression, 2.7 MPa for bending.
- Shelf life: 8 months in the package without damage.
Preparation of putty
Preparation is important, because due to the use of the mixture not according to the rules, damage occurs, technical characteristics are reduced. We process the surface, without fail, clean it from dust and dry it. It will not be superfluous to pre-priming. Before carrying out work, the surface must be thoroughly cleaned, otherwise there is a possibility of deterioration in the quality of adhesion of the putty to the sheet. Characteristics of the place of application - strength and hardness. This guarantees the quality.
On the proper cooking solution draw Special attention. 1 liter of water is used per 2 kg of dry mix, mixed until a homogeneous mass is created. It is not recommended to exceed the amount of putty for this volume of liquid; if the mixture is too fluid, it will flow down the wall.
Only clean equipment should be used for mixing, since only in this way there will be no unnecessary impurities in the composition. Tools that come into contact with putty are made of stainless steel.
There is 50 minutes to apply the resulting mixture, since after this time the material will set and harden in the vessel. It will be impossible to use it.
Putty mixture Knauf Uniflot is intended for use in internal works. Reinforced tape is not required.
Applying putty Application
Application takes 1.5 hours and occurs in two stages. In the first, cracks and holes are filled. Then, after an hour, the surface is covered with a second layer. It is advised to work with a wide spatula. If there are any irregularities, they should be cleaned. Do this with fine-grained sandpaper. Coarse-grained should not be taken, since it is intended only for primary processing, and not for polishing the surface. Exactly according to the same principle, the fasteners that you want to hide are puttied.
After all the prepared mixture has been used, it is necessary to immediately rinse the containers and tools that were used. If the plaster remains in the package, then it is carefully closed so that it does not pick up moisture from the air and does not harden.
Result of work The benefits of putty

The purpose of Uniflot Knauf putty and its characteristics
The technical characteristics of Uniflot (Knauf) putty, its purpose are determined by the composition of the material. The basis of the building mixture is gypsum. It provides the putty with ideal plasticity, which allows you to create an even layer, qualitatively close up irregularities, roughness, and depressions. The material is environmentally friendly, so it can be freely used in living quarters. Gypsum base does not provide a mixture of high moisture resistance. Therefore, the data Construction Materials used for interior work.
Uniflot Knauf putty is used in finishing:
- Ceilings
- Partitions
- sexes
The material is ideal for sealing joints between sheets and Knauf boards. In this case, reinforcing tape does not need to be used. Ready putty can be applied in layers of 1-5 mm. Consumption Knauf Uniflot per 1 m 2 when finishing partitions, walls is 500 g, when finishing ceilings - 300 g. The strength of the layer for bending is 2.7 MPa, for compression - 5.2 MPa. The material dries quickly, so the amount of the prepared mixture is calculated for 20 minutes of work. Due to the high rate of hardening of the solution, one hour after applying the first layer, you can proceed to the finishing putty.
Benefits of Knauf UNIFLOT, material reviews

Advantages and disadvantages
Among the analogues of putties, Knauf Uniflot is confidently in the lead. Due to its properties, this material is not only safe and easy to use - it has a number of undeniable advantages that make it one of the most purchased and sought-after compositions. In particular:
- does not shrink (which means it will not crack after drying, which is especially important for seams and joints);
- relatively easy to use (although it requires some experience);
- allows you to form a flat, uniform surface;
- is cheap;
- can be applied to almost all modern building materials (including heat-insulating ones).
The material still has drawbacks, but they are not related to quality. This material requires a certain amount of experience, both when mixing and when applying.
How to apply?
Apply the material only on a dry and even surface, without oils and other substances complicating bonding. If you are renovating and not building from scratch, then paint or wallpaper should be removed from the walls and partitions. Although textured plaster is still used for this.
The mixture is diluted as follows: 2 kg of dry mixture is poured into a liter pure water and stir until smooth. The “recipe” is general informational and does not encourage action - The right way cooking must be read on the packaging!
Remember that the mixture will begin to harden after 20 minutes - so you have a limited amount of time at your disposal.
This makes the application process less convenient if you want to cover large area(and this is usually the case with repairs). You simply will not have time to apply the solution to the surface of all the walls of the room (for example), and you will have to prepare it again.
However, this drawback is not too significant, and it takes a minimum of extra time. And in fact, almost all solutions from other manufacturers have the same properties, so you should not focus on this.
Now we will describe in stages how exactly the application of Knauf Uniflot will look like (and, in fact, any other putty):
- The surface is cleaned from the old coating, dust and dirt.
- Ideally, the surface is primed to improve the adhesion of the putty.
- The solution is prepared in the required amount.
- The application is carried out with a spatula (metal or plastic) - the solution is smeared with it over the surface, after which it is leveled with a plumb line.
- The first layer of putty is recommended to be no thicker than 5-7 mm (again, read the instructions on the package).
- Cracks, joints and chips should be treated several times.
- After the layer has dried, it should ideally be cleaned with sandpaper.
The second layer (and subsequent ones, if any) is applied only after the previous one has completely dried. Then you can putty on the walls under the wallpaper and apply plaster on the wall.

Knauf UNIFLOT special putty for joints is designed for sealing joints of gypsum boards and panels based on them (panel finishing elements, perforated and slotted panels). When using UNIFLOT putty, butt joints are sealed without the use of reinforcing tapes. Particularly recommended for sealing transverse joints of gypsum boards (edges with chamfered).
Surface preparation:
Sub-base surfaces must be sound, firm, load-bearing, clean and dry.
Cooking:
Pour a maximum of 2 kg of dry material into 1 liter of clean water and stir with a trowel until the consistency of sour cream. It is not necessary to leave to swell. Use clean containers and tools for mixing. Working time before the start of setting is about 20 minutes.
Knauf Uniflot consumption:
The consumption of putty depends on the shape of the processed edges in the seams between the plasterboard panels.
Operating procedure:
Work with a spatula with a screwdriver and a wide (20 cm) spatula. Longitudinal joints of construction gypsum boards with a semi-circular edge (HRAK) and other joints (chamfered edges) can be puttied with UNIFLOT in two passes within about 1 hour without the use of reinforcing tapes. UNIFLOT dries and hardens very quickly.
Fill the seams by pressing the material with a spatula. After a short exposure (after about 30 minutes), remove excess material in places where thickenings appear. Possible minor irregularities should be lightly sanded with grout.
Fastener details are also puttied in 2 passes.
Seized material must not be recycled due to the risk of cracking!
Rinse tools and containers immediately after use with water (gypsum residues reduce the time of work with the material of subsequent batches).
