ᐅ How can I close the gaps between Ikea PLATSA furniture units?

Hello everyone, I recently assembled some Ikea Platsa furniture units and noticed that unsightly gaps appear between individual modules, even though they are supposed to fit flush together according to the assembly instructions. I am therefore very interested in how to best close or conceal such gaps so that the overall appearance looks more harmonious. Are there any common tricks or specific materials suitable for filling or covering these spaces? I am particularly interested in a solution that is both visually appealing and stable, since the furniture will be used daily. I look forward to your experiences and tips!

Gaps between IKEA PLATSA modules usually occur due to slight manufacturing tolerances or uneven floors/walls. To close these gaps, the following solutions are recommended:

- Use of foam or self-adhesive sealing strips that adapt well and conceal the gaps.
- Insertion of spacers or precisely sized wooden strips fixed between the modules.
- If visual concealment of the gap is desired, plastic or wooden panels can be used, which can be painted or covered to match the surface.

It is important that the stability of the units is not compromised. I recommend installing additional screws or corner brackets between the modules to prevent movement. Proper alignment before final fastening is also essential.

Simply cut spacer blocks from wood or plastic and glue them in place. Then seal the gaps with clear acrylic or silicone. This method is durable, stable, and looks neat.

I completely understand how frustrating gaps like these can be, especially when you’ve put a lot of effort into building something and want the result to look flawless. What helped me was not just filling the gaps with material, but also realigning the furniture entirely. Sometimes the problem starts with the floor or the wall not being perfectly straight. In addition, I bought small MDF trims and painted them to match—this not only cleverly concealed the gaps but also gave a very professional finish. It takes a bit of patience, but the result is really satisfying.

Absolutely! I enhanced my PLATSA corners with self-adhesive edge strips, commonly used in kitchens – minimal effort, and the outcome is worth it. The small gaps just disappear, and you instantly feel like a furniture designer. 😉 If the gaps are larger, just cut narrow strips and apply them as if giving the furniture a little “trim.” It’s really fun to customize things yourself like that!

I can confirm this. Silicone is recommended because it remains flexible and compensates for slight movements between the modules without cracking. For visible areas, clear silicone should be used to preserve the appearance. Those wanting a more professional approach can also use color-matched acrylic sealants, which are easier to paint over once dry. A combination of mechanical fastening and this type of sealing provides the most stable and visually appealing solution overall.
