How to spread putty for walls

Putty is a building material in the form of a paste, designed to align ceilings and walls before further finishing. It contains film-forming elements, coloring pigments and fillers that have the ability to fill and eliminate cracks, as well as smooth uneven surfaces. For a clear leveling of surfaces in the room where the repair is carried out, it is first of all important to know how to spread the putty and to observe the correct mixing proportions. In addition, you must be able to properly use putty, know the methods and technology of its preparation, features mixing (density of consistency), important rules for applying and working with this mixture, and also to understand the types putties.

Types of putty

• Putties prepared for use. Sold ready-made in plastic buckets. The peculiarity of this substance is its short storage.

• Dry mix - designed for mixing. Sold in bags and is the most common use case. The advantage of dry mixes is the low and affordable price, convenient transportation, the possibility of preparing any degree of viscosity you need, as well as a long shelf life. The disadvantage of dry types of materials is that the resulting mass must be applied to the surface as soon as possible after kneading to prevent its hardening.

Types of Binder

• Cement. Hard putty with a cement base is characterized by high water resistance, and it is intended for use in rooms with a high level of humidity. The disadvantage of this substance is precipitation after application to the surface, after which it is necessary to apply an additional layer. Also, this type hardens relatively slowly, due to which small microcracks may appear.
• Polymer. This type is the best and high-quality coating, but because of the high price, fakes are often found.
• Gypsum This species does not sag. It can be applied in a thin layer. The disadvantage of this type of substance is the fear of temperature and moisture.

The choice of putty

• Starting - is intended for primary processing of surfaces of window and door slopes, walls and elimination of irregularities. Often starting putty use instead of plaster. With proper dilution of the putty, you can achieve good adhesion of the substance to the surface, which is much better than that of plaster. The advantage of this type of solution is the drying rate. For example, the plaster becomes in 25 -28 days, and the starting putty in 3-5 days.
• Putty for applying a second layer - designed to apply a thin layer of several millimeters. It consists of fine fractions. It is sold in convenient plastic bags, and is used in the last stages of applying the material to walls and other surfaces. This type of substance is very convenient to knead.
• Special putty - designed for special needs. The purpose is indicated on the package. There are several types: acid-resistant and waterproof.

Putty preparation

Putty preparation is a very responsible process, since in order to know how to properly dilute a substance, it is necessary to understand for what stage of finishing work it is necessary.

The starting putty should have a thick consistency, for applying a very thick layer that will hide any uneven defects in the walls or other surfaces. Thickness drawing a layer on walls or the ceiling can be up to 5 cm, so the material must be applied in several layers. In order for the solution not to “float” and not to set too quickly, it must be diluted with clean river sand, observing a 1: 1 ratio. This method is used exclusively for interior finishing work on gypsum mixtures. A good, thick layer of the applied material on the walls or ceiling should not cause shrinkage, deformation or cracks.

Finishing putty has high requirements and cooking technology. For internal finishing work, mixtures prepared on the basis of gypsum are used. Experts say that the dry fraction should be very fine, so that the coating of walls or other surfaces will be perfectly smooth.

To prepare the mixture, you need to prepare

1. Capacity. For kneading you need a capacious bucket of plastic or any container of convenient shape. If there is no container made of plastic, any galvanized or enameled container can be used. But it is the plastic container that is best suited, since it is very convenient to knead in it.
2. Next, you need to prepare clean water at room temperature without debris, dust and rust.
3. In order to qualitatively dilute the mixture, the best option is to use a drill with a nozzle. The drill must have a smooth start so as not to splatter the room, and rotation in both directions. The ideal speed for mixing the mixture would be 600 rpm, which will help to mix well and saturate the mixture with air bubbles. If there is no such drill, you can rent it at a supermarket or a tool company for any period you need. If options with a drill are not possible, you can stir manually, but this is a very time-consuming process.
4. You will also need a paint brush, a container of water and a small spatula.
5. A container of water designed to wash nozzles from a drill.

How to spread putty, step-by-step instructions

1. It is necessary to fill the container for stirring with water in the quantity indicated on the package.
2. Next, you need to wet the walls of the tank, as they must be wet.
3. Pour putty into the water in quantity, according to the instructions.
4. The mixture should be in water without stirring for 5 minutes, it should turn sour.
5. Then you can start the process of stirring. If necessary, add additional mixture or water.
6. Wash off the unused putty from the edges of the bucket. This can be done with a spatula or brush. Stir further by moving the nozzle from the drill clockwise and counterclockwise, up and down.
7. Pull out the drill and dip it into a container of water, turning it on at a low speed to wash the nozzle (if this is not done on time, the nozzle will remain in putty).
8. The resulting consistency takes 15 minutes to infuse, after which you need to add a few tablespoons of PVA glue, which will strengthen the consistency, give elasticity and softness.
9. Mix again and the resulting solution can be used as directed.
