Why blisters and wrinkles fiberglass on the ceiling

Those who prefer to see fiberglass on the ceiling probably have come across more than once such a problem as wrinkles and bubbles on it. This phenomenon has different reasons. To avoid problems, it is important to do everything right at the gluing stage.

Technology violation

First, the ceiling is leveled. If the surface is uneven, this will somehow affect the fiberglass and as a result there will be bubbles and wrinkles. But this is not enough to completely eliminate the risk of the problem.

First you need to glue the fiberglass mesh, then putty, and only then glue the fiberglass. If you only glue fiberglass or only fiberglass mesh, then the material may wrinkle. After sticking fiberglass, it must be smeared with the same glue that was used previously. To do this, coat the surface with a roller so that the pores clog.

To avoid irregularities, it is better not to stick with the method of precisely joining one layer of fiberglass to another. It is much more convenient and practical to apply the overlap method when one layer 2-3 cm comes on another. If done by the junction method, the likelihood of wrinkles and bubbles is high, even if the master is experienced. Just because it is a person who does it, not a machine.

It is important that the fiberglass sections are large, otherwise the likelihood of bumps will increase significantly. With the overlap technique, it becomes necessary to trim the remaining area. This is done with a knife, but very carefully, because the material is very moody and requires delicate handling. If you push too hard, there will be a dent, from which wrinkles and bubbles are possible. Also, do not use too much glue, otherwise this in itself can cause bubbles and wrinkles.

Substandard materials

As for glue, you should not save on it. Cheap adhesives from unknown brands are a dubious choice. However, it is important to understand that the brand largely affects the price, and therefore glue that is too expensive, although it is good, can still be found cheaper and cheaper.

Of course, the fiberglass itself must be of proper quality, otherwise wrinkles and bubbles may not be the result of illiterate gluing technology, but the reaction of the material itself to glue. And if a person does not understand in time that the problem is in the materials, he can lose a lot of time on redoing the work, believing that it was he who made a mistake somewhere.

In conclusion, it is worth noting that it is worth practicing in cutting off surplus fiberglass in advance. Most likely, for the first time it will be very unusual, and the likelihood of errors is high. It is important to correctly calculate the pressure, remember the sensations and then apply when gluing fiberglass.
