A floor can be perfectly laid and the baseboards can be beautifully chosen…
but without good finishing, you see it immediately.
Gaps, crooked seams, or poorly finished corners make the whole look messy. And that’s a shame, because finishing is what makes the final result.
Why sealant and finishing are so important
In practice, baseboards almost never fit perfectly against the wall.
Especially in Spain, where walls are often not completely straight, small seams and gaps appear. Without finishing, these remain visible.
By neatly sealing baseboards:
- you seal seams tightly
- you prevent dirt buildup
- you protect the baseboard from moisture
- you create a calm and finished look
It’s a small detail, but with a big effect.
Which sealant do you use for baseboards?
Not every sealant is suitable. The right choice makes the difference between a lasting neat result and cracks after a few months.
Acrylic sealant (most used)
Ideal for baseboards along walls
- paintable
- flexible
- suitable for indoor use
Silicone sealant
Only use in damp areas like bathrooms
- water-resistant
- not paintable
In most cases, acrylic sealant is the best choice for baseboards.
Finishing: what should you watch for?
Good finishing is more than just applying a bit of sealant.
We always pay attention to:
Tight seams
No excessive sealant edges, but neatly finished
Neat corners
Both inside and outside corners must fit tightly
Treating end grains
MDF baseboards absorb moisture through the end grain, so good finishing is essential
Top coating
For a durable and neat final result
Common mistakes
This is where it often goes wrong:
- using too much sealant → sloppy result
- using the wrong sealant → cracks or discoloration
- seams not finished → gaps remain visible
- no attention to corners → cheap appearance
These are exactly the things that make a floor look “cheap,” even if it isn’t.
Sealant and finishing in Spain
Due to temperature differences and humidity, materials expand and contract more than in the Netherlands.
That’s why flexibility is important:
- use of the right sealant
- correct application
- good finishing
This is how you prevent seams from cracking over time.
The finishing touch
The difference between a floor that is “neatly laid” and a floor that is truly finished lies in the details.
Sealant and finishing may seem minor, but they ultimately determine how neat and well-maintained your home looks.
