What material is used for filling tile joints and gaps between walls?
When you want to renovate a room without removing old tiles or need to repair gaps between walls, you need an elastic, resistant material with strong adhesion. The recommended solution is Crack and Gap Sealant – A4, a single-component polymeric product designed for professional repairs and uniform finishes.
Why use A4 Sealant for tile joints?
When you want to install new flooring over existing tiles (e.g., carpet, SPC, or vinyl flooring), the surface must be flat and without gaps. Deep joints between tiles can create unevenness and affect the final appearance of the new flooring.
A4 Sealant is ideal for:
-
Filling joints between tiles to obtain a flat and smooth surface.
-
Leveling small gaps so that the new flooring has a solid and uniform base.
-
Preparing the substrate for a clean and professional installation.
Use for gaps between walls and buildings
In addition to interior finishes, A4 Sealant is also used for sealing gaps between walls or buildings, where elastic, movement-resistant, and weather-resistant solutions are needed.
-
High elasticity prevents cracking due to natural structural movements.
-
Water and UV resistance makes it suitable for outdoor use.
-
Durability recommends it for expansion joints, areas exposed to rain and temperature variations.
Main advantages of A4 Sealant
✔ Elastic – does not crack or peel.
✔ Resistant to UV and weather – for indoor/outdoor use.
✔ Can be painted – perfectly integrated into the finish.

✔ Durable and safe, suitable for long-term work.
Conclusion
If you want to prepare a floor for new installation or fill visible joints and gaps in walls, A4 Sealant is the right solution. Versatile, resistant, and easy to apply, it provides uniform and protected surfaces, both indoors and outdoors.
