It is no secret that a significant part of the reinforcing mesh on the market is from anonymous and unknown manufacturers. Can you trust them? It is clear that all of them as one assure that their product meets all the necessary standards, but is this so?
We are a Ukrainian factory for the production of facade mesh. Our products are certified and are constantly sold to the countries of the European Union. This is a consequence of the fact that we constantly control the quality of our fiberglass mesh. We know everything about this control and will share with you.
First tip: You exist just as long as your papers do
The surest way to check the quality of the reinforcing fiberglass mesh is to examine its quality for a month in a special laboratory. It is clear that everyone does not have such a laboratory. But there are those who have it! And the specialists working in them issue certificates of conformity. If a manufacturer gives you such a certificate, it means that mesh has already been checked for quality. Moreover, with the most picky methods. We have such certificates. Moreover, not only Ukrainian, but also European.
Second tip: bend-break!
The facade mesh must be very strong. As it will have to maintain an alkaline pH in the drying plaster. The easiest way to test its strength is to bend and unbend it several times in the same place along twisted yarns. If it starts to shaggy or break, strength is not enough. Also try to break it with a sharp movement. If you are not a terminator then a quality mesh should hold up.
Third tip: visual inspection
Fiberglass mesh is rolled up. Take a closer look at this roll. A bad plaster mesh is often immediately visible: a roll is uneven. The contours of the cell can be displaced by light effort. The edges are tousled. If the roll is even, well packed, and the manufacturer is indicated on the label, then there is a high probability that the mesh will be normal.
Fourth tip: check for persistence
Unwind some of the plaster mesh and crumple it. If it straights up immediately, regains perfect shape, so it is good. If it remains crumpled for a while, it is bad.
Fifth tip: crash test
Make an experiment: “insulate” a piece of the wall, for example, meter by meter. Do everything well, let the plaster dry to the end. And then have some fun: knock on it with a hammer, throw heavy things at it, play baseball at last. Examples of such checks you can find in various videos on our Youtube channel. If it makes the plaster crack and fall off, there is no need to talk about any monolithic structure. You have a low-quality mesh, or maybe plaster too.
