Putty from Knauf: start and finish of finishing work

Putties under the Knauf brand: starting, finishing and universal - are an integral part of any construction. This German company has long been engaged in the production of finishing materials and has managed to gain recognition around the world. Capital repairs in the apartment inevitably associated with the alignment of the walls. To do this, you need a starting and finishing putty. The first is necessary for the preliminary (rough) preparation of the base, the second - for the final stage. Let's see why it is worth giving preference to Knauf, because in the construction market, putties are represented by a fairly wide range.

Peculiarities

All putties from Knauf are ready-made mixtures that absolutely anyone can use. For convenience, all products are packaged in paper bags of 25-30 kilograms. Putties are divided according to the method of application and composition. The following categories can be distinguished:

Putty start. It is made on the basis of gypsum or cement. It can be used for finishing walls and ceilings in residential premises. Due to its composition, it has a good margin of safety and provides additional sound insulation.
Finishing mixes. The composition does not need additional grout after application. In fact, this is a finished surface finish.
Universal compositions. Differ in fast grasping. In order for the universal putty to grab the base, it is enough to wait only 30 minutes. It is worth noting that such a mixture fully justifies its name. It can be used to level walls and ceilings and eliminate joints. In addition, these compounds can be used on any surface. They contain astringent polymer additives that provide reliable adhesion.

Varieties of Knauf mixtures

Surely not all people are professionals in construction. Some people only try themselves as a finisher and therefore do not know which Knauf mixture should be preferred. Therefore, for beginners and professionals, we will make a brief overview of gypsum-based starting mixes. For interior decoration, it is recommended to use gypsum-containing mixtures. They are more convenient to use and less prone to shrinkage compared to cement compositions. So, let's begin.

Knauf Rotband

The best option for interior finishing. The mixture can be called universal. It is suitable for leveling concrete, brick and polystyrene substrates, and can be applied to walls and ceilings. In addition, the putty is immune to damp environments, so it is suitable for work in bathrooms and kitchens.

Knauf Goldband

In fact, this is a variation of the previous plaster, but there is a significant difference between the two mixtures. For example: Goldband is for walls only. The composition does not contain adhesive components. Therefore, after complete drying, the putty can simply crumble from the ceiling. But it is ideal for processing brick and concrete bases with deep relief. It should be noted that Goldband can be applied in a fairly thick layer - up to 50 mm. The remaining characteristics of the putty are identical to Rotband Knauf.

The main component of the building mixture is high-quality gypsum, which is an environmentally friendly and lightweight material. Packing weight — 30 kg.

The mixture is plastic and easy to apply, it is easier to work with it than with other types of plaster.
The coating provides good heat and sound insulation. The consumption of gypsum mixture is much lower compared to cement.

Mode of application

Work with dry Knauf starter mixes occurs according to the following scheme:

Preparatory stage. Before using a rough putty, it is necessary to prepare the base. To do this, remove all contaminants from the surface. By the way, the recommended temperature of the treated surface should not be lower than +5 degrees. After that, the main surface must be prime. This is especially true for surfaces that absorb moisture well. For example: aerated concrete blocks or silicate brick. As a primer, you can use Knauf products: "Betonkontakt" or "Rotband-Grund". These primers are diluted with water in a ratio of 1/3 and applied to the surface with a roller or paint brush. Further work can be carried out only after the primer has completely dried. After that, beacons are installed on the surface. These tools will make your workflow much easier.

Technological process. Consider the procedure for working with Knauf dry mixes using the example of START HP. The composition is diluted in proportion: 1 bag (25 kg) per 14 liters of water. After falling asleep, the mixture must be thoroughly stirred until a homogeneous mass is obtained. This can be done by hand or use a mixer.

The solution is applied to the base with spatula. Before setting, it is necessary to level the putty on the installed beacons. It is worth noting that prepared solution must be used within 30-40 minutes. If the putty will be applied in two layers, it is recommended to make the surface of the first wave-like. To do this, you can use a special spatula.

Helpful Hints

The putty layer should not exceed the values specified by the manufacturer. Otherwise, after drying, the composition may partially crumble.
If the composition is applied in 2 layers, it is recommended to use a reinforced mesh. A second layer is applied only after the previous one has dried.
After using each portion of the mixture, the inventory must be thoroughly washed.
It is better to dilute the Knauf starting putty with cold water. If the mixing water temperature exceeds +30 degrees, the putty may crack after drying.
If you used the Knauf composition for the rough finish of the walls, then it is recommended to use the products of this manufacturer for the finishing.

Anna

Knauf putties were used during the first repair 5 years ago. Not the slightest crack or shedding was noticed. It was easy and pleasant to work with them. Now I recommend Knauf to all my friends when the question of high-quality putty arises.

Answer

Ivan

Perhaps now something has changed, I now take cheaper local mixtures. But earlier, the cheap putty of this company was called "Finish", and "Start" was plaster, as it is actually written on the bag in the photo.

Alexander

I had to work with a mixture from Knauf HP Start. All in all, a good starter mix. When properly mixed and applied, it does not crack. After drying forms a reliable layer. It has good adhesion to all types of surfaces (concrete, brick, gypsum). True, do not forget that this is the starting mixture and it will still be necessary to apply finishing putty on top.
