ᐅ How do I secure IKEA Metod kitchen cabinets to rough wall surfaces?

Hello everyone,

I am currently planning to install an IKEA Metod kitchen, but I have the problem that my wall is not a smooth plaster, but rather a rough, uneven surface (it is old clay plaster with sand content). My question is very specific: How can I securely and permanently fasten the Metod kitchen cabinets to such uneven, rough wall materials?

I am mainly looking for advice on choosing the right wall anchors or fastening materials, any necessary wall preparation, and load distribution. I am also interested in whether there are special techniques to consider with inconsistent wall textures to prevent the cabinets from becoming loose or, worse, falling down over time.

I appreciate any detailed help or shared experiences, as this is my first time doing this and the structural safety of the wall cabinets is very important to me. Thank you!

Hi codyle,

I’ve also mounted IKEA kitchen cabinets on an old wall with a rough surface before. My secret tip: don’t skimp on the fasteners! It’s better to use a few extra anchors to ensure a very strong hold.

Of course, chemical anchors always work well, but especially with a rough surface, adding a small wooden batten as a base, which you screw horizontally onto the wall, can help. This creates a level surface for the mounting rails—a sort of base board.

It might sound like more work at first, but it makes installation easier and provides better stability.

Important: Choose heavy-duty anchors for the weight and drill with the correct drill bit, otherwise you might run into problems with the cabinets holding or staying mounted 🙂

Good luck!

That is indeed a very good tip. Mounting wooden battens as a support frame on the wall can effectively even out irregularities and also stabilizes the installation.

A small technical note: When using wooden battens, pre-drill them and use sufficiently long wood screws with appropriate wall plugs to ensure the substructure remains stable. This also allows you to screw the metal rails directly onto the wooden base, reducing the need to drill through plaster and rough clay plaster.

However, be careful with damp walls – wood can expand or warp, so the material needs to be properly treated (e.g., pre-impregnated or painted).

That sounds very interesting, especially the part about easier installation. My goal is for the cabinets to hang as straight and secure as possible.

I’m curious about that. I’m considering attaching the battens specifically where the wall cabinets will be installed.

How long should the screws and wall plugs ideally be if I have a lime plaster wall 3-4cm (1–1.5 inches) thick with solid brick behind it? I don’t want the screws to be too short, but I also want to avoid the risk of screws penetrating too deep and tearing out.

Hello codyle,

for about 3-4 cm (1¼-1½ inches) of clay plaster on solid brick, I would recommend the following guidelines:

- Anchors with a minimum embedment depth of 8-10 cm (3-4 inches) into the brick
- Screws into the battens should be chosen so that at least 4-5 cm (1½-2 inches) grip in the batten, with the rest in the wall

In practice, this usually means: 8 mm (5⁄16 inch) anchors with a length of 80 mm (3¼ inches) and screws about 60 mm (2¼ inches) long.

This provides sufficient load-bearing capacity and prevents cracking caused by too short fasteners.

Generally, it's better to allow a few millimeters more if the material thickness permits.

It is also important that the holes in the clay plaster are drilled and cleaned thoroughly, as there are often loose particles and debris. Otherwise, nothing will hold well.

Hello,

for the Metod rails, precise installation is important. Use a spirit level and a long straightedge to ensure everything is perfectly aligned. Otherwise, the parts may click or shift over time.

If the plaster is too crumbly, it can help to stabilize the holes with epoxy adhesive or expanding foam before inserting the wall plugs.

What always helps: Tighten the screws several times and check again after about 2 days to ensure everything is still secure. This is especially important with rough walls.
