We carry out the walls before the filler primer

We carry out the walls before the filler primer

primer filler walls in front of absolutely necessarily have to perform, because it will provide a reliable contact with the wall decoration materials and allow a repair will last as long as possible.

soil application serves more than one purpose:

  • improves paint adhesion and fillings with fine surface;
  • strengthens the base;
  • smoothes the surface;
  • improves (reduces) the absorbent properties of the surface;
  • protects against mold and mildew.

For priming use special mixture, the concrete has a concrete, metal, wood, stone, brick.

primer may be in the form of a concentrate, as a ready to spray composition.It should be said about the kinds of primers separately.

primer Types

Primer walls before applying the putty - a collective concept, the essence of which is disclosed to use athe specific type of surface composition.

Today, there are 7 kinds of primers:

  • Acrylic - as well as paint, this primer is applied by all surfaces, including old or new plaster, concrete, cement, wood, brick, chipboard and fiberboard.Acrylic primer does not smell chemically and dries very quickly - for 3-4 hours.Acrylic primer does not protect the metal surface, but on the contrary, due to the moisture and alkalis promotes rust;
  • Alkyd - the best choice for wood.When applied, it swells, creating a surface receptive to many surface finishes.Primer 10-12 hours for drying varies depending on the main component - zinc phosphate or zinc chromate.Primer should not be closed and plastered plaster surface;
  • Gliphtal - used especially in dry conditions.Dries for the whole day, can be applied as a primary coating on the front of the main metal surface;
  • perhlorvinil - the best choice for metal surfaces as concrete and brick.Drying at room temperature for 1 hour, but in an unventilated room, and the more residential, categorically not used;
  • Polyvinyl acetate - the record for speed of drying - only 30 minutes!But its use is very narrowly focused - strictly under the paint and only polyvinyl acetate;
  • Polystyrene - very toxic undercoat, which is not used indoors.Suitable for the most part as a sub-layer wooden and plaster surfaces;
  • Phenolic - primary coating for metal and wood, dries in 12 hours.

errors priming

Before we describe you really simple guide (with videos) for priming the walls, read with errors that often make the householders while attempting priming their own hands.

If the wall intended for painting, the paint without priming lasts 5 times less than the due date: 1-2 years it will crack, sometimes bulges to, begin to fall off.

Video:

always better to once again cover the primer, because no matter what surface you nor treated filler, gypsum or alabaster, rather than miss a preventive measure.

primer used on all surfaces - before and after leveling walls.So, if you ignore the priming and immediately shpatlyuete all the irregularities, there is a risk that the coating will be unreliable.

not be confused at first sight identical compositions from different manufacturers!

Their properties may vary as the mixing, in one mixture, and after - if one portion of a structure to be covered and the other part - other.If gruntuete, only one brand!

Rare tip: add a few drops of bright pigment in the composition prior to the application, and you will see where the dyed through, and where not.All the same primer in the end will be closed topcoat.

Breeding ground all at once in the water - a luxury, not a different way: in the best case, you will spend half of the mixture on the wall, and the rest can still be useful in the future.

Use addition roller and brush still: the joints of the walls and all corners must also be primed.

Primer walls with latex paint and polymer formulations unacceptable: such compositions easily absorb water, that will manifest itself in six months or a year in the same bathroom, toilet.

Let's say you chose acrylic, water-dispersion paint for coating.That means that the soil should be similar to the acrylic.

unspoken rules of soil choice: ground selected primarily based on surface features and spaces, and only after several kinds of targets selected the one that best fit the desired surface finish.

And remember the main thing - a primer is not a fad, but an important security element of future coverage, because in any case it should be applied.And sometimes two and three times in a row for a reliable result.

Besides soil price does not necessarily mean its "super" part of: the simplest domestic cope better than any European.

And the price for the most part - payment for the brand, although there are among import truly unique compositions.

But they are mostly needed for piece work with expensive materials that are not used in the normal repair.

soil deposited on the surface

Before we proceed to the application of the soil, to learn the basic rules.Use rubber gloves: primer - aggressive environment.Wear gloves and goggles.

If you are using a spray gun, be sure to wear a dust mask.Take the time to read the instructions in the package and gained ground - there was not a way of preparation.

surface before priming should always be free of dust and debris.If the surface of the wood, it removes all the burrs.Shake the ground before use.

Pour it into the tray with a ribbed edge, dip the roller into the tray, walk a couple of times in the ribs and then can be rolled along the wall.

Apply primer by roller strictly vertical movements - so the surface will be covered uniformly.

Using the airbrush, pay attention to whether all areas are equally sprayed with primer or not.Treat the wall in parts: charted at eye square meter, processed, moved on.

treated walls first layer - let it dry completely.After re-coat the entire wall of the ground again, so get completely uniformly impregnated surface.

Spread the composition in a plastic bucket according to the instructions.

not pour more water, despite the fact that the composition may seem thick - primer will be diluted and generally will not stay on the wall.

Mix in a bucket with an electric beater-mixer until uniform composition: note, after mixing the composition thickens slightly - as it should be.Apply primer evenly.

Argued that the brush can be easily applied primer - this is not true!

Firstly, you spend a lot of time, causing the soil shallow brush, secondly, the brush will begin to lose and have to nap after another to carry out an audit of the whole surface for the pile.

Do not let the appearance of puddles on the wall - use a better roll (as in video): it is wide and easy to use, and if also with a telescopic tube, you can even be primed ceiling.

good primer - always double: after drying, apply a second layer, and then the ground is entirely fulfill its properties.

Conclusion

Priming as an important procedure that her care and the fact that implementation of all determine the quality of the subsequent finishing.

Primer - a bonding agent between the wall and the subsequent coating, because it can not be neglected in any way.

In addition, taking into account all the above, it turns out the conclusion that the priming of the walls with his own hands to perform under the force of each.The main thing - to choose the right soil and well clean the walls.

A roller wield a lot of experience is not necessary: ​​moknul-unrolled-moknul.That's the technology.It should be said about the cost of the ground separately.

Price primer generally small - about 150-200 rubles per liter, but the price of concrete-contact above, moreover, it is sold in cans and the most precious thing you can find on the market today - imported soil into the canister 20 litersat the price of a maximum of 2,500 rubles.

These 20 liters is more than enough for dozens of square meters of walls.Price, of course, vary depending on the composition, manufacturing country, but is available to all.
