Review of budget options exterior finish of foam at home, the choice of materials

Construction of low-rise buildings of the "bricks" of artificial stone because of its cheapness is considered one of the best budget options to address any housing or economic problems.But this is not entirely true, since unlike many other building materials, foam concrete has significant drawbacks - unpresentable form and a porous structure.Consequently, the external decoration of the house of foam blocks - a mandatory phase of construction work, for whatever purposes it was not intended.

But how and what it do to the overall costs grew not so much?This question requires a consideration of the objective.Consider the most popular, inexpensive and proven finishes.

• staining.
• plaster (plastering).
• banding.

What to consider

Regardless of the method of the external design, care must be taken that the effective water vapor permeability of the walls has been provided.It is this that determines the choice of materials, technology and production work.In addition, it has a value and quality waterproofing, as the foam still partially absorbs the liquid, although not as intense as its closest "relative" - ​​gas silicate.

to dwell on all the technological operations on the outer wall surface does not make sense, as this is a topic for another article.But what criteria should choose wall and other materials on which the nuances of design should pay attention - this is to understand in detail.

Paints

The only valid option (unless, of course, take care about the quality and durability) - silicone compositions.Such paints for sale relatively recently, and have a wide range of applications.Their virtues can find the most comprehensive information on many websites.But what exactly are good for foam?

• hydrophobic.This means, if we talk more simply, that, no matter how much rain did not knock on the walls of the house, not a single drop of liquid through the layer of paint does not penetrate.That is, the silicone compositions at the same time make an attractive colored foam and provide adequate waterproofing of the material.
• vapor permeability.Consequently, the artificial stone can "breathe."And it is - one of the main requirements during the cladding of foam.
• resistance to aggressive chemicals.In our times, "acid" and "alkaline" rain, unfortunately, not uncommon.

Plaster compositions

All such mixtures (solutions) after hardening to form a layer which "breathes".But in order to extend its maintenance-free operation, it is necessary to make the reinforcement.For this purpose the grid, which are fixed to the aerated concrete.The cost of such a finish is low, so it is a viable option.

But we are not talking about the panels that mimic the decorative plaster.They are not vapor-permeable, so they label on foam - is clearly not the best solution.

Plastered façade

pretty quick way to trim is not particularly difficult.In the process of preparation of the solution is injected into it an appropriate dye, so the house can "decorate" somehow.Of course, this technology - for an amateur, but in terms of maintainability - a great option.

Facing materials

Whether that will be purchased, it should be noted:

• between the cladding layer and foam is necessary to leave a small gap.This compensates for the lack of natural ventilation of water vapor permeability of finishing material;
• lightweight designs.The porosity of the foam is virtually synonymous with "lack of strength" (looseness).This explains the difficulty of fixing the artificial stone of fastener elements.

With regard to the second factor to choose the most suitable materials for the walls is somewhat limited.For example, the widely advertised fiber cement wall panels mounted hardly advisable.Even if it will securely support frame, then during operation (for example, in the wind), he gradually loosened the taking into account the total weight of the lining material.Whatever spoke hired masters of high quality batten fixing, it is better not to risk it.

What to choose

• Coat wall insulation (eg mineral wool) and lined with brick in 1 row.There are some recommendations.But this method of decoration called a budget is difficult.Even without taking into account the cost of the bricks need more and additional strengthening of the foundation, which is - again costs.
• panels.The range is quite large.But if we take into account their cost, the best option - PVC products (plastic siding).The advantages are many - quick installation (can independently read like), light weight, little or no maintenance (if necessary, easy to clean), and so on.In combination with the foam - one of the cheapest combination.

Consumables

mesh for reinforcement .Plastic desirable, given the small thickness of the plaster layer.Choosing from the entire range should be preferred materials resistant to alkalis.

Reiki supporting framework .Use samples from the timber is undesirable.Such slats are heavy of themselves, and gradually plus otsyreyut that only increase their mass.For lathing with fastening on aerated concrete is better to buy an aluminum profile.

fastener elements .The fact that the frame plating need screws, clear.But as his bond with the basis, if necessary to provide a gap for ventilation, and fixing brackets can not be directly on the wall?The same applies to the masonry, if you still decided to finish to make it to her.For these purposes, use the spiral nails basalt-plastic bond.

In principle, all of the most simple and useful options for exterior finishing foam addressed.And what is to stop a choice - up to you, dear reader.
