What should be putty and what kind of tool to cook?
For preparatory work on leveling the surfaces before the final( finishing) stages of finishing work, special compositions called stoppers are often used. These compounds are used to seal small irregularities, cracks and other defects in the finish, and are very important for a quality appearance. In fact, they represent a layer on which the face coating is applied: wallpaper, paint, varnish and so on.
Depending on the purpose and types of putties are divided into compositions for internal work and for external use. Fillers can be purchased as a dry mix or a set of components. To prepare the working composition, it is necessary to add water or to mix the ingredients according to the manufacturer's instructions how to use the putty. Very often manufacturers offer different fillers in the form of ready-to-use paste-like mixture.
In addition, many types of fillers can be easily prepared by prescription using different types of glues, varnishes, polyester resins, cements, gypsum, chalk, soap and other ingredients.
We put the putty correctly
As it is already clear, gypsum or cement can be used as the basis of putty, widely applied fillers based on polymer compositions. On this depends on how to apply the putty. So, according to the manufacturer's recommendations, it is better to use cement-containing fillers to prepare surfaces for subsequent wallpapering, and for better coloring the surface is better to be filled with gypsum or polymer compounds.
High-quality fillers have high adhesion, are easy to use, can be used on a fairly wide range of materials. Since the main purpose of the formulations is leveling, their deposition is carried out in a sufficiently thin layer, which ensures a high profitability of their application.
Depending on the composition, the puttying technique may involve the use of various spatulas( metal, plastic) or allow the use of special sprayers.
So, how to use the putty? Its application is carried out in various ways, a thicker layer in places of damaged damage and thin at the edges, taking into account the obligatory subsequent grinding. The first layer is superimposed along the long side of the surface by parallel strips. The next layer lies necessarily perpendicular to the leveling movements.
It is necessary to carefully level out any incrustations and irregularities on the embedded surface. So the consumption of putty is reduced, and after drying it is easier to achieve ideal smoothness by grinding for subsequent painting, pasting, etc.
Accompanying operations for
putty When performing surface finishing works, putty represents an important but still preparatory operation. If you imagine a master class on putty, its precedence is preceded by preparatory work for thorough cleaning of the surface and its degreasing with different compositions, depending on the material of the substrate.
By the way, degreasing can be carried out, for example, with the help of a solution of copper sulfate( when preparing for painting with aqueous compounds) or acetone( when preparing a car wing), depends on what the surface material is.
Further - cutting of cracks and defects, primary priming and partial shpatlevanie. If necessary, the next step is again applying a primer layer, this operation can be carried out repeatedly, including on the already applied layer of putty.
After the formulations dry, grinding is carried out to eliminate minor defects, and in a complex case and, if necessary, a new cycle of finer work on priming and puttying is carried out. So gradually the surface is removed to the required level of "cleanliness" for final processing.
