ᐅ Are expansion joints absolutely necessary?

We had an appointment today with a flooring installer to discuss the installation of glued vinyl. The topic of expansion joints also came up.

The installer said he could either use the expansion joints made by the screeding contractor.

In that case, install an expansion joint profile, then lay and glue the vinyl on both sides, and seal the joint with silicone?

Or cut the expansion joint made by the screeding contractor with an angle grinder, clamp it, bond it with epoxy resin, and then glue the vinyl over it?

We don't like the appearance of the first option at all. For the second option, I'm not sure if it complies with current technical standards and installation guidelines.

Are there any other possibilities or tips to avoid this silicone seam?

Please take them over. The screed installer doesn’t do this for fun.

Yes, I have now also found networking that you probably can’t avoid. So, we will likely have to live with it...

It is also possible to use mesh to bridge expansion joints.

Not really. The flooring installer offered this. He glued commercial-grade tape over the joints and then laid the parquet flooring on top.
