Tip 1: How to plaster the exterior walls

Due to the simplicity of implementation, the use of readily available materials and cost-plastering work is very often used in the treatment of the facades of buildings.Penetrating moisture in the raw wall reduces its thermal insulation.You have to spend additional energy for heating homes.And emerging from the damp mold harmful to health of family members.Stucco exterior walls to prevent the negative impact of weather conditions.
you need
  • - watering can or sprayer;
  • - large brush;
  • - metal brush;
  • - cement, sand, water;
  • - bucket (1 liter);
  • - building level;
  • - float, trowel;
  • - rules and beacons (aluminum rails).
To obtain a satisfactory result start treatment of the facade with the preparatory work.New brick house with moisten a sprayer or watering can.It can plaster without primer.And if you have an old brick house with walls over dried before plastering works sweep up the dust from them.For this it is useful to a large brush having stiff bristles.After wetting the walls pro
ceed to the primer.
plaster exterior walls can be carried out using a special grid.To do this, fix it on the wall and apply the mortar on top of the grid.
And you can set the brand - small areas of the proposed solution is the thickness of the plaster, which, strictly on the level, are fixed beacons (aluminum rails).The interval between the beacons - 1 m from the corner stand back, please, 20-30 cm. To be safe, secure beacons bottom plugs.After installing beacons allow the solution to 4-5 hours for hardening.
for spraying a mixture of plaster, use rule (aluminum rail), a bucket or a falcon (a special plate).A spreadable solution spreader, moving it from the bottom up.Leveling plaster solution using established beacons, moving slowly upwards.The surface is further align rule.
Plastering follow with a solution of 1 part of cement, water, and 3 parts of the sifted sand.Apply a thin layer of soil in several stages, thereby decreasing the occurrence of shrinkage cracks.The thickness of about 5 mm, apply a first liquid layer (scratch coat) so that it penetrated into all the pores.This will provide strong adhesion primer to the surface of the wall.
Wait until dry and harden one layer, and only then apply another layer (ground).To do this, take a thick solution.From this basic layer depends on the thickness of the plaster (3-10 mm).
To better keep the top layer of plaster layers dried out walk with a wire brush.This will increase the roughness and therefore the reliability of coupling of a plaster layer.Upper extremity alignment layer (finish coat) having a thickness of 2 mm.
plaster exterior walls come to its final stage - the grout.Firmly press a grater to the wall, making it (anti-clockwise) circular motion.
plaster exterior walls completed.Then proceed to the whitewashed walls.

Tip 2: How to plaster the house

Outside plastering buildings serves two purposes: protecting walls of the house from the elements and to give them the decorative properties.In some cases, it is necessary - if the material of the stacked wall requires protection from direct contact with water (cellular concrete blocks, for example).In other - made solely to improve the appearance of the house.Decorative plaster can transform the look of your house, giving it a unique charm and originality.
How to plaster the house
you need
  • - plaster;
  • - set of tools for stone and plaster works (trowel, kirochka, poluterok, trowel, brush and so on.);
  • - a plumb;
  • - cord;
  • - nails.
Clean the wall from dust and dirt, remove nodules solution.If the material is a smooth wall (brick, for example) make the wall notch a chisel with a hammer, ax or a grinder with a special range.The depth of the notches must be about 5 mm, the distance between neighboring strokes - about 50 mm.During this work, use goggles and a respirator.
Set beacons simultaneous reconciliation of the wall (the term "reconciliation" means to check the verticality).
Hammer a nail into the top right corner of the wall so that the length of its protruding portion is equal to the thickness of the plaster layer (15-20 mm).Hammer a nail into the bottom right corner, adjust the position of the tip of the plumb line, attached to the top of the nail head.Do the same with the left side wall.Thus, the heads of nails hammered in the corners of the wall will be in the same vertical plane, which is to become the surface of the plaster layer.
Set over the entire surface of the thick walls of lighthouses solution or nails, correct their height on the cord, stretched between nails, installed in the corners.Number of beacons depends on the degree of your professionalism, the lower it is, the more it should be.Normally, the distance between the beacons taken 100-150 cm.
Mix the plaster or purchase ready.The best is a lime-cement mortar.Lime present therein gives it ductility and contributes to maintaining the technological properties over a relatively long time.You can prepare a solution and one cement, but it will be less malleable and will lose the ability to laying.The ratio of components in the lime-cement mortar 1: 1: 6 (lime - cement M400 - sand), cement - 1: 4 (cement M400 - sand).
Apply a preliminary layer of plaster.If the wall is dry, moisten it with water.Spreads mortar trowel wall, maintaining the desired thickness (height beacons).Throwing by wrist movement is easy, not too strong and not too weak.We must adapt himself to perform such movements to the solution comes at the right place and firmly stuck to the wall.Sketched an area of ​​about 1 m² aligned plaster surface poluterkom beacons.If necessary, add a solution in places where it was not enough, and put them in those with a surplus.
Repeat cycle "impingement-alignment" as long until the whole wall will be plastered.Making the angles of the house is made by planed boards pressed against a wall so that its edge is on the level of other beacons wall.
When plastering the wall is finished, cut with a trowel on the surface of the wavy lines depth of about 5 mm and the distance from each other 40-50 mm.They need for tight adhesion to the surface finishing layer, which is to be put later.

During the week, several times a day moisten with water wall and cover it with sackcloth, vellum, or something similar to protect it from sun and wind.
1-1.5 weeks later apply the finishing (decorative) layer of plaster.Its thickness should be 5-15 mm.Composition
plaster content of sand and binders must be approximately the same as the pre-mixture.In addition, it added color pigments and various components (marble chips, broken glass, gravel certain faction, etc..) To obtain the necessary external effect.

plaster surface can be smooth (after smoothing) or relief (the spray, pressed, cut, rolled, etc.).You can make imitation of decorative stones.For each case has its own special technology.We must decide that you need and follow its requirements.
  • outdoor and decorative plaster
  • plastering homes
Front assembly in any case should not be carried out without prior preparationsurface, as in this case the plaster mixture adheres poorly to the wall.Forming "Quilted" plaster falls off in large chunks.
Too thin layer of plaster does not hide wall irregularities, and a very thick layer can crack during solidification.
Helpful Hint
If you do not spend plastering works quickly, add a solution of water or a solution of 10% bone glue.In this case, the curing process is slowed down.
