Quality repair or whether the need to wash the walls before the filler ?

primer filler walls before - the key to success

Anyone who decides to do their own painting and decorating the house, faced with the problem that at first: a primer or putty?The answer is simple - the primer.Whatever the material was not in the base surface - metal, concrete, wood, plaster, - cover all future it must be firmly.For this primer is used, which penetrates deeply into the substrate and makes adhesion better with the following coating.

primer has adhesion properties and secure, so it prevents damage to the base layer.In addition, the primer layer promotes uniform ink absorption and overlay, plaster, adhesives, fillers and so on.As a result, the quality of the final finish becomes much higher. Note!Before use the primer, it is necessary to prepare the surface.

Naturally, you can not bother with primer, but in this case the quality of the repair will be much lower, and further peeling plaster, wallpaper lag behind, but due to the effect of moisture on the surface there will be cracks and stains.Therefore, the application of a primer is recommended because it provides an additional guarantee of quality.

to handle different surfaces and using different primers.It is necessary to consider the type of coverage, conditions and characteristics of the premises, and a post-finishing.They can be divided into two groups: a primary primer compositions and surface treatment to improve the adhesion between the materials.They are produced on alkyd, mineral, acrylic and other basics.

plastering work

Even thick layer of primer follow the contours of the surface.Therefore, to make it smooth and to prepare for further work, the plane shpaklyuyut.The dried filler can be sanded easily, which allows for a perfect flatness.All modern plaster is a dry mixture, which is charged with water or ready to use paste-like mixture.They are divided into leveling and finishing.

Leveling used for "rough" surface of the pre-alignment.They have been applied in a layer of 0.5-2.5 mm at a time.Plastic solution is done, so that after drying shrinkage and not turned spreading.The finish coat is required for removal of small defects, scratches, cracks.Apply it is usually a layer no thicker than one millimeter.Very thin layers called Superfinishing.Overlap

they 0.1-0.2 millimeter in several layers with intermediate drying.Care should be taken to see to it that the total thickness of the layers does not exceed the maximum thickness, otherwise the surface can give a crack. Note!Maximum allowable thickness is different for each mixture, and it is indicated on the packaging.

Calculate and save

primer and putty material is the most expensive with the finishing work, but still worth it to calculate in advance which class mix is ​​needed and how much it will take to work.This simple calculation will allow to guard against extra costs and so is not a cheap repair.It is necessary to think over the whole course of the work, make a plan and follow it.This will avoid problems such as priming putty after.Moments that should be taken into account:

• Calculate the area of ​​the treated surface;
• From the square, to calculate the number of necessary primer and putty (you need to read the instructions on the packaging, where the flow rate is specified);
• sure to take into account the type of surface;
• take into account the necessary alignment surface;Buy
• mixture with a small margin.

Important!Each material has its degree of absorption, however should be considered when calculating the time.

drawing up the plan, taking into account these factors, it is possible to secure the most reliable and trouble-free operation.For a more accurate calculation is best to consult with a professional or a person who has experience of such work.
