What to do if the stretch ceiling sags from water
Stretch ceilings are a quick method to create a flat and beautiful surface. But in some cases, the owners are faced with the trouble - the ceiling sagging. If it happens in an apartment, and it is usually immediately assumed that the neighbors have flooded from above. But this is far from the only possible reason, and in this article we will tell you why the stretch ceiling sags and in which case the warranty period is valid. In addition, we will look at the methods of correction.
This problem may appear due to poor quality materials or defects at all working stages. We suggest considering all possible reasons.
Errors when measuring
Before starting installation work, it is necessary to accurately determine the width and length of the ceiling. However, the size of the opposing walls may start to differ. In case of errors in measurement, the web will be cut incorrectly.
If it is made of film or fabric with a glazing bead, the discrepancy does not affect anything, because the material will be taken with a margin and cut after installation. But the PVC canvas with a harpoon is made strictly in size, from which the sagging of the stretch ceiling canvas appears. Such a mount can be found much more often, and therefore the problem is very popular. If the canvas turns out to be very large, then the installers are able to cut off excess material on the spot and re-glue the harpoon. This is a great practice when installing a stretch ceiling.
Incorrect cutting of canvases
The film heats up and stretches during the installation process. In production, the dimensions of the canvas are made slightly smaller than the ceiling area. The stretch ratio will differ from material to material. If a lower coefficient was used in the calculation, then the film will turn out to be a lot and sagging will form during shrinkage. The problem will still be resolved on the spot by reshaping and re-harpooning the web.
Poor quality material
Please note that these are not all potential problems. Quite often, this film has an extremely pungent aroma, and this will mean that the content of harmful substances in it is exceeded.
In this case, only buying a new canvas will save you.
But it is better to immediately order stretch fabrics from popular and proven manufacturing companies. Quality certified materials will last longer and are not hazardous to human health.
Violation of installation technology
Wall moldings are most often used as a frame for a tension type canvas, which will be attached to a partition or drywall boxes.It is much less often required to choose ceiling profiles (they are located on the base floor). For the frame, it is required to choose the correct fasteners and observe the required distance between the points.
If you screw it badly (on those screws that do not fit or just very rarely), then after a while the baguette will move away from the surface. This will form a gap, the tension will weaken and the canvas will sag.
A similar situation occurs with fragile wall surfaces - loose or those made of drywall sheets without additional reinforcement. In the first case, the surface will begin to crumble at the place of fixation, and in the second, the drywall sheets will begin to crack and break. As a result, the baguette begins to move away from the wall surfaces and the fastening will weaken.
Installers must correctly identify wall materials and prepare appropriate fixings. If the frame still does not hold reliably, then the problem can be solved by screwing in additional self-tapping screws, installing spacers or replacing the fasteners.
When the stretch ceiling sags, it will be wrong to think that it can be pulled to perfect evenness. Both PVC film and fabric will have a certain weight, and they will be supported along the edges. For this reason, slight sagging is natural, and its dimensions will be influenced by the following characteristics:
According to the standards, the sagging should be no more than 1% of the length of the canvas diagonal.
In a room with a standard size (15 to 20 square meters), this deviation will be invisible even in the center of the ceiling surface.
Please note that if the room is huge (from 30 to 40 square meters), then experts advise using several canvases at once. Between them there is a special baguette for separation, into which the film will be tucked from both sides. The gap will be closed with a camouflage insert to match the shade of the canvas.
Not always the reason for sagging may lie in poor quality installation.
options can be very different.
Sagging from water
PVC film does not allow moisture to pass through, and if neighbors flooded you, then the liquid begins to accumulate in the canvas, which stretches under the weight. Due to this, when proceeding, the rest of the repair work and pieces of furniture will be saved. To distinguish such a case, you need to move your hand over the bubble. You can also feel the heaviness and rolling of the water.
It is extremely important that if such a nuisance is found, it is required to immediately de-energize the room. Otherwise, a short electrical circuit is possible.
The film is perfectly stretched, then it breaks from contact with sharp objects.The sagging ceiling is examined and anything that can spoil the canvas, for example, the edge of a cornice or a chandelier, is removed. If a lot of water has accumulated, even pencils and pens in a tabletop stand will become dangerous.
Further, it is better to call specialists who probably know what to do. In addition, if you do work on the ceiling yourself, the warranty starts to disappear. But if the warranty period has expired, and there is little water, you can try to cope with the problem yourself. You will need an assistant.
Under no circumstances should the film be punctured or cut! Under pressure, even a small hole will diverge immediately.
Instead, it is required to remove a chandelier or spot lamp. One person puts a bucket under the hole, and the second gently "rolls" it to the required place with water. Another method is to use a hose. If inserted into the hole and directed to the place of accumulation of water, and the other end is thrown into a bucket. After removing the liquid, the film will remain stretched.
To restore the surface, you will need to dry the material with a heat gun. In mild cases, you can get by with a powerful household hair dryer. The film will heat up and re-stretch.
Inflation from air
The cause may be gaps in the floor of the basic type, walls or at the joints between them. So, air will get inside, press on the canvas and stretch it.
In some cases, the effect appears constantly, in other cases it appears in a draft when the windows are open. To make sure that it is for this reason that the stretch ceiling sags, you need to slightly raise the film near another hole - the wind will start blowing from it. In order to remedy the situation, there are a couple of methods that are used together in some cases. The first is to remove the canvas, fill up all the cracks and mount it back. The second is the installation of ventilation grilles.
It is best to find secluded places for them - above the closet, in the corner or behind the cornice.
Deformation from winter cold
PVC cloth is subject to the influence of temperature - from the heat it will increase in size, and when it cools it will shrinkage. This quality is used during installation work to obtain smooth surfaces. But from the cold, the film will shrink very strongly, and it may even begin to deform and crack. For this reason, PVC canvases are mounted only in houses for year-round use, which do not begin to freeze in winter.
Plaster, which falls off
Before starting the installation of the stretch fabrics, it is necessary to prepare the base. The remnants of the old finishing material are removed from the main floor, and then primed. If this is not done, then after a while the plaster, lime and so on begin to crumble. Small pieces will start to bulge ugly, and more can stretch the canvas.Determining that the film began to sag due to falling construction debris is quite simple.
If you run your hand, you can feel the perfect and solid surface, and in certain cases, the pieces are visible visually. In order to fix everything, you need to remove the canvas. After removing all unnecessary, the overlap is cleaned and primed. Then you can pull the film back.
When the ceiling sags, the question arises as to whether the installer should fix the problem or will need to deal with it himself.
The list of warranty service includes such cases in which the manufacturer or installers are to blame:
Such errors the company is simply obliged to eliminate - to correct the minuses, to replace the material or return the money. If the ceiling surfaces have sagged for other reasons, this cannot be attributed to the warranty case. The fact is that it is not the installers of stretch ceilings or the manufacturers of paintings that are to blame. It is also possible to fix everything, but for an additional fee.
To use the warranty, the following conditions must be met:
- A contract with the manufacturer has been signed.
- Nothing was done with the ceiling surface by yourself, and if you installed cornices or lamps on your own, then you removed the canvas and so on, the circumstances disappear.
So, now you have learned what to do if your stretch ceiling has begun to sag. But an unpleasant situation is easier to prevent than to correct. So that there are no problems, or at least easily solve them, you need to take a responsible attitude to the selection of a company. The best firms work only with materials from trusted manufacturers and provide a guarantee for services.
You also need not to forget about the prepared work, as well as to close up all joints and cracks in the ceiling. Clean the base coat if the old finish may fall off and additional surface strengthening with a primer is required.
