Waterproofing of ceiling materials and the use of

Most residents of apartment buildings and private houses think about waterproofing the ceiling is too late, that is, in fact - flooding neighbors at the top or roof leak.To avoid these troubles would allow a small range of activities that can be inscribed in the scheduled maintenance.Today, we will discuss what materials are used for waterproofing ceilings, and how you can do it with his own hands, saving on hiring construction crews.

Why do it?

easy to guess that need waterproofing the ceiling to the top in the house does not penetrate water.It can happen for various reasons - from neighbors above burst aquarium, they forgot to close the tap, or just a pipe burst.For owners of private houses waterproofing important than ever, as to complain in case of leakage will have only their own indiscretions.

In addition, waterproofing to avoid the appearance of mold and mildew due to excessive fumes in the room such as a bathroom or kitchen.It protects the insulation layer, which when wet ceases to perform its protective function.Thus, the waterproofing not only gives water to spoil the interior and trim, but also prolongs the life of the insulating material of the ceiling.

It is important to remember that flooding the neighbors from above is fraught not only property damage but can cause much more damage.The water can wet the wiring and cause a short circuit with fire as a result.Particular attention should be paid to waterproofing the ceiling in the bathroom, kitchen and other rooms with high humidity levels.Because they always or very often present of evaporation, which is known to tend upwards, the inner ceiling finish is extremely vulnerable and require protection.

But here's the paradox - to perform the waterproofing inside the ceiling in principle wrong.As the main threat - is flooding from above the water with their weight will put pressure on the protective layer, and it may tear.It is much wiser to isolate the outer surface of the ceiling, but by coincidence, this is outside of the floor in a neighbor's apartment.And it is unlikely the neighbors will be delighted if you come to them with this idea, and will need to remove or at least parquet linoleum, floor mastic to cover up for the safety of their own homes.That has wisely and select materials that would be convenient, and most importantly, effectively guard against accidental flood.

Materials for waterproofing

waterproofing materials, there are many, but the ceiling - the surface is quite specific, and work is not so easy with it.But resourceful wizard still manage to select effective ways to protect a wide variety of ceiling materials.Let us consider each of these in more detail.

lining hydraulic seals

This whole section of waterproofing materials, the most prominent representative of which is a roofing material.Okleechnaya called any waterproofing that needs to be stick or overlay on the prepared surface.Usually sold in rolls, such as plastic film, glass, polypropylene and other synthetic fabric functional analogs.

However, a significant disadvantage of this type of material is just in the process of applying them to the surface.If you've ever tried to glue the wallpaper on the ceiling, you immediately realize what is meant.Roofing felt, even the cheapest and most ordinary, much heavier than wallpaper, but because dealing with it even more difficult, and not the fact that it will hold firmly.And at the first qualitative flood of neighbors above such waterproofing can successfully fall off, along with a decorative coating.This prospect will please very few people, so the lining hydraulic seals for ceilings used infrequently.

Stretch ceilings

This method is much more popular than pasting the ceiling with polyethylene, but is much more expensive.Stretch ceilings deserved recognition not only an interesting look and high aesthetic, but also the ability to reliably protect the house from uncontrolled encroachment neighbor's water.In the case of the Flood fluid accumulates just under the ceiling and can not seep through his painting.If the water natechet enough, the ceiling will turn into an interesting spectacle, more like an avant-garde art object, as, for example, in the image below.

But even if the fabric slack right up to the floor, it does not miss a drop of moisture.The liquid then is discharged through the holes for fixtures, decanting safely in the container.The film cloth structure is able to withstand up to 100 liters of water per 1 m² - no waterproofing can boast such figures.

The disadvantages of suspended ceilings, in addition to their cost, can be attributed the fact that the installation they significantly reduce the height of the room, so are not suitable for all apartments.If such a ceiling safely rescued you from flooding from the top, and you decant from under him water, the work is not finished yet - the space between the ceiling and the concrete should be dry cloth.And to make it very high quality, otherwise there is a risk in a short time to get moldy or mushroom plantation, hidden from the eyes.To do this, probably have to shoot the whole film to dry it, and then installed on site.

Yet benefits have suspended ceilings are much larger, and therefore installation completely justifies any sacrifice.This coating not only protects against moisture from the outside, but also creates a perfectly flat and smooth surface - no whitewash and plaster will not achieve this.Installation of a stretch ceiling, though specific, but it is fast and does not leave behind the dust and dirt.It is an ideal solution for the above rooms with high humidity - the film does not miss evaporation and keeps the dry concrete floor.

surface waterproofing

With surface waterproofing all much easier than with back-lining.It includes a number of liquid mixtures which are applied to the surface of a roller or brush.Mastics are usually rubber or bitumen-polymer base, therefore creating a sufficiently reliable and durable waterproof film.

to part well behaved on the ceiling and does not peel off the water pressure from the top, the surface should be carefully prepared.Often the preparatory work takes much more time than applying the most protection.This is the disadvantage of these materials.The ceiling should be first cleaned of old coating and primed several times.The primer should be chosen not anyhow how, and deep penetration - such formulations penetrate the concrete slab, brick or other porous material, which safely freeze, increasing the strength and water resistance of the overlap.Outside primer leaves a film adhesive, which adheres well to any surface waterproofing.

important point: As a part of practically all waterproofing mastic contains organic solvents in the process of working with them need to open all the windows and doors to provide proper ventilation.Based on this requirement, it can be concluded that the deal with the processing of the ceiling in the winter cold is not a good idea.

K of coating and waterproofing materials include liquid rubber, a relatively recently appeared in the construction market.This substance, which is based on two-component mastic asphalt.In it there is not a toxic substance, and drying time is almost instantaneous compared with one-component formulations.However, if you do not want the liquid rubber has fallen off from the ceiling in six months, you must choose a trusted manufacturer of quality products, most likely to pay a round sum.

Penetrating waterproofing

This method is the most common, and not only because the cheapest, but also because of the good quality indicators.The operating principle of penetrating waterproofing is a bit like a primer of deep penetration: substance seeps through the pores of the concrete to the maximum possible depth, which crystallizes and firmly fixed.Therefore, micro cracks and openings in the ceiling are sealed, preventing moisture to seep inside.

An important point: often the depth of penetration into the concrete structure depends not only on its quality and the manufacturer, but also the temperature at which the work is carried out and the degree of surface moisture - warmer and wetter the concrete is, the more deeply penetrate the waterproofing.There are compounds that can be impregnated concrete by 60-80 cm They cost quite expensive, but fortunately, for concrete floors in apartment buildings, they do not need -. Quite suitable cheap compositions that penetrate only 15-20 cm

Waterproofing the ceiling inside.in most cases carried out in the domestic market of the popular CT mixture of "Tron-1."We propose to consider in stages, how to handle it:

1. surface of the concrete slab must be properly wet.To do this, simply wipe it with a damp cloth several times, sprinkle with water from a spray or a wet walk with a wide brush.
2. When the water soaks the concrete can be applied penetrating structure.Doing this the best general construction brush with synthetic bristles.
3. hand movement should be carried out in one direction - you should not carry a few times on the same site.
4. Apply a thin layer of waterproofing is better.When the first layer is a little grab, but not harden completely, you can proceed to the next application.Total sufficiently 2-3 layers.Before again plastered ceiling, it is necessary to moisten it again - the water is conveying means for the composition of the microparticles into the ceiling.
5. Each subsequent layer must be applied perpendicularly to the previous.

On 1 m² covered in 2 layers, will require about 0.8 kg of "Tron-1" on the condition that the surface is smooth.On the rough ceiling will take about 1 kg / m².

During operation, pay special attention to the joints of the walls and ceiling, as it is the most vulnerable point.During the construction of apartment buildings often walls and floors combine conventional concrete, which eventually gives a strong shrinkage rassyhaetsya and begins to crumble.Water seep through this place a piece of cake, and to prevent this from all the angles and joints should be carefully promazyvat penetrating waterproofing or sealant, even if you are then going to install the suspended ceiling.

important point: After you have made the waterproofing of the ceiling in the house with several layers of a mixture of penetration, maintain the relative humidity of the surface for 3 days.This will allow the composition to penetrate as deeply as possible into the concrete.

Waterproofing wooden ceiling

If you have a wooden cottage or country house, which has heating, and you are going to use this good civilization in the winter, insulation and waterproofing ceiling required.Summer moisture evaporation occurs by itself, but in the winter a lot more evaporation, and they linger inside longer, because the temperature is lower, and the windows and doors are permanently closed.Also, if you plan to live in a wooden house in the cold season, non-insulated ceiling will give you a constant cool and huge heating bills.As you know, the hot air is actively seeking up, and if it does not create a barrier in the form of protective layers of the ceiling, there is nothing to prevent him from leaving the room, you're trying so hard to heat.

If insulate the ceiling with mineral wool (the most popular and inexpensive material), the evaporation from the bottom, passing through it will create condensation heater fed with them, and cease to keep warm.If you just stick to the ceiling waterproof film, heat will also leave, because the film is, unfortunately, only protects from moisture.Thus, the insulation work with a ceiling in a wooden house must be done in conjunction with insulation, hydro-and vapor barrier.The latter is not only a barrier to vapor, but also protection from dust and small litter, which can be showered through the wooden roof elements when walking on the top floor.

The most simple and inexpensive polyethylene film vapor barrier is considered, for which the attachment can be used an ordinary stapler.This material should be mounted overlapped by 15 cm and fasten the strip between a wide adhesive tape.Vapor barrier is placed on the heater, and it - on top of the waterproofing.

How do you waterproof ceiling:

1. By wooden beams of the ceiling, attach the waterproof film - building 200 m thick polyethylene, polypropylene fabric or other for fixing to wooden surfaces, use a stapler, and between a wide cuts of material connect the tape..Lay the waterproofing overlap by 20 cm.
2. top of waterproofing insulation film attach.This can be a mineral wool plates or rolls, foam or other material nesypuchy.By the way, if you do waterproofing ceiling baths, the heater should be selected non-flammable and the most impervious to moisture.Mineral wool in this case loses - as soggy, completely loses its protective abilities.But as in a dry form, it retains heat very well, many continue to use it by adding an additional layer of waterproofing - on both sides of the insulation.
3. insulation lay on vapor barrier membrane that does not allow condensation to penetrate.In the case of waterproofing the ceiling with his hands in the bathroom, bath or kitchen instead of the vapor barrier (or with it), you can put another layer of waterproof film.Cuts membrane should also be laid overlap by sticking to a tree by a stapler, and to each other - wide tape.
4. top of the vapor barrier or additional waterproofing is necessary to beat wooden slats - a kind of crate for fixation of finishing material.Racks tightly hold not only the ceiling trim, and a ventilation gap is left which is necessary for the evaporation of the condensate.
   

Good to know: In wet areas the use of a vapor barrier is necessary.Membranes are different: one-sided and two-sided.If you bought a one-way, it is necessary to lay down a rough and smooth - up (for insulation), two-way can be fixed arbitrarily.Bilateral steam expensive, but allows you to not leave the ventilation gap.In the bath, steam room of many experienced owners placed a vapor barrier of kraft paper coated with a foiled - it evaporates condensate and reflects heat back into the room.

If on the top floor has a rough floor, it is best to lay the waterproofing on it - it's easier, faster and more reliable.As for the ceiling waterproofing on the balcony in a wooden house, it is also better to carry out, attach the rear of the additional insulation and a vapor barrier.

We hope the above information will help you in time to take care of the protection of their own homes and avoid trouble with leaks and floods.
