ᐅ Vinyl Flooring in Kitchen / Sagging Beam Ceiling / Installing Over Tiles?

Hello everyone,

We have taken over a house from my parents. We will be installing a new kitchen and want to lay a new vinyl floor with a thickness of 7.5 mm (0.3 inches). Currently, the floor in the middle of the room (from left to right) has slightly sunk by about 4 mm (0.16 inches).

We would like to install the vinyl flooring over the tiles (only up to the skirting board of the new kitchen, as otherwise we would need 8 mm (0.3 inches) thickness). However, we are concerned that the floor might sink even more. Under the tiles, there is a screed layer, beneath that OSB boards, and under those, joists.

How should we proceed?

Looking forward to your advice.

Thank you

Three options:
1. Lay over it and leave it like that – then the floor will remain uneven
2. Apply leveling compound
3. Remove the entire floor including the screed and redo it

Personally, I would choose option 1.

So, you think that would hold in terms of weight?

I would apply a leveling compound first and then install the floor, because otherwise the vinyl floor might flex without enough mass, I think.

Vinyl hardly weighs anything. And some settling of the floor is completely normal – this is stated on the instructions of every type of insulation you place under the screed.
Are you suggesting the floor has a problem with 6kg/m² (1.2 lbs/ft²)? That’s nonsense.

Since 1.6 m² (17.2 ft²) weighs 25 kg (55 lbs), plus the mass added, it will definitely be more than 6 kg/m² (1.2 lb/ft²), I think. We’re just concerned about the additional load. But we are also laypersons.

You want to install vinyl flooring. That will never weigh that much. Typically, vinyl weighs about 6kg per sqm (1.2 lbs per sq ft). Additionally, there will only be a few millimeters of leveling compound on a small area, which is practically negligible. Ceilings are designed for permanent loads of at least 150kg per sqm (31 lbs per sq ft), not including the safety margin that is also included.
