What do users say? AI-generated summary

Users rate the sealant very highly, praising its strong adhesion and flexibility in particular. It is often used to fill cracks and joints in walls, floors, and outdoor areas, with reviewers noting its durable results and good value for money. However, some say it yellows in the sun, doesn’t adhere well to painted surfaces, or may have dried out inside the packaging.

  • It’s easy to work with (especially if, before applying it, you leave the cartridge in the sun in summer and in the sink with lukewarm water in winter for the appropriate amount of time), and it seems to adhere well if the surface is properly prepared and a backer rod is used to reduce the depth of the crack. Remove any loose material and wipe the bonding surfaces with industrial acetone for paint (not the kind used for nails!). I applied it to areas that aren’t stable due to minor settling/movement, e.g. outdoor steps, to keep moisture from getting through, since conventional grout cracks.

  • Excellent adhesion! I filled some gaps between an accordion-type aluminum system and the wall. The color matched perfectly with the RAL7038 aluminum color.

  • Very good price!
    Elastic as it should be.
    It yellows within 1.5 months when in direct contact with the sun and peels off if applied on a painted surface.

  • Either the packaging was old or the company is worthless! It was so dried out inside, it was useless, I struggled for nothing! I went and bought one from a paint store and got my job done! Money wasted

  • One of the best I have ever tried, strong adhesion and elastic... I don't know about durability over time
